Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council Appeal Decision Inquiry held on 17 and 18 June 2025 Site visit made on 17 June 2025 by J Woolcock BNatRes (Hons) MURP DipLaw MRTPI an Inspector appointed by the Secretary of State Decision date: 23rd July 2025 Appeal Ref: APP/G2245/W/25/3359260 Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent DA3 8NX • The appeal is made under section 78 of the Town and Country Planning Act 1990 (as amended) against a refusal to grant planning permission. • The appeal is made by RES Ltd against the decision of Sevenoaks District Council (SDC). • The application Ref is 23/03181/FUL. • The development proposed is “Construction and operation of a solar farm with all associated works, equipment, necessary infrastructure and biodiversity net gains. New access track.” Decision 1. The appeal is allowed and planning permission is granted for: Construction and operation of a solar farm with all associated works, equipment, necessary infrastructure and biodiversity net gains. New access track. At Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, DA3 8NX in accordance with the terms of the application, Ref 23/03181/FUL, and the plans submitted with it, as amended, subject to the conditions in the attached schedule.

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council Preliminary matters Battery storage 2. After the planning application was validated, batteries were added to the proposed development. These are referred to in this decision as a Battery Energy Storage System (BESS). No details were submitted about the BESS other than a drawing showing a Typical Battery Storage Enclosure.1 However, areas were shown on the Infrastructure Layout for ‘Inverter & Battery Storage Area’.2 The scheme proposes direct current (dc) connected batteries sited adjacent to inverters, so the BESS would be dispersed across the site. SDC’s Application Report referred to the batteries, but the description of the development was not amended to include the BESS. I queried at the Inquiry whether it would be necessary to include the BESS in the description of the proposed development, but the parties were content to rely on the submitted plans and the reference in the description to “all associated works”. 1 CD1.30. 2 CD1.20. https://www.gov.uk/planning-inspectorate

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council Appeal Decision APP/G2245/W/25/3359260 Reasons for refusal 3. SDC refused the application in July 2024 for four reasons, which are in summary, inappropriate development in the Green Belt, adverse effect on the setting of heritage assets, negative effect on landscape character and visual amenity, and because the loss of Best and Most Versatile (BMV) agricultural land had not been adequately justified. 4. SDC Members resolved at an extraordinary meeting on 8 April 2025 not to contest two of the Reasons for Refusal. Its Statement of Case provides that the Council exercised its duty to reconsider the case in light of recent policy changes and planning appeal decisions. SDC determined that although harm would be caused by the proposed development, the Green Belt and loss of agricultural land reasons could not be sustained and were withdrawn. The Council added that the remaining reasons were insufficient to outweigh the benefits of the proposed development.3 5. In its opening statement to the Inquiry SDC cited new policy and guidance about grey belt land, and how other appeals had dealt with agricultural land, as reasons for not defending these grounds.

Page 2 · Chunk 3

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council Regarding the remaining reasons for refusal, SDC accepted that landscape harm was limited and that the effects of the proposed development on landscape accords with national and local policy and so is acceptable. SDC noted that some less than substantial harm to heritage remained in respect of harm to the setting of listed and non-designated Mussenden buildings. However, given the planning benefits of the proposal, particularly the need for renewable energy generation, SDC concluded that the benefits of the appeal scheme significantly and demonstrably outweigh the harm to landscape and heritage, and so did not defend the appeal.4 Amended appeal scheme 6. Proposed amendments to the scheme were submitted with the appeal in January 2025. The design changes comprised: • Removal of panel arrays and infrastructure from Field 9. • Addition of a low-level timber post and rail fence either side of the Public Right of Way (PRoW) Route SD333 in Field 9. • Provision of one additional skylark plot within Field 9 and associated planting to increase biodiversity net gains. 7.

Page 2 · Chunk 4

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council I concur with the parties that these are minor changes that would not significantly alter the proposal from that considered by SDC in refusing the application.5 The proposed amendments were included on the appellant’s and SDC’s websites. A newspaper advertisement was published on 16 January 2025. Site notices were placed at the main access to the site and on Footpath SD333. Letters of notification were sent to Ward Members and Parish Councillors, as well as Parish Councils and 202 local residents and businesses. The consultation period ran to 25 March 2025.6 Local residents referred to the amended scheme in written representations and at the Inquiry. I am satisfied that no one would be prejudiced 3 CD10.7 paragraph 1.3. 4 ID1. 5 SoCG1 CD10.8 paragraph 4.12. 6 SoCG2 CD10.9 section 2. https://www.gov.uk/planning-inspectorate 2

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council Appeal Decision APP/G2245/W/25/3359260 by considering the amended scheme and I have dealt with the appeal on this basis. Proposed development 8. It was clarified at the Inquiry what details were to be determined as part of the appeal and what other details would be subject to further approval were the appeal to succeed.7 The Infrastructure Layout Plan would secure the siting of the following; • access tracks, • inverter and battery storage areas and associated hardstanding, • temporary construction compounds, • substation compound, • fence lines, gates and CCTV, • drainage infiltration trench, • site entrance visibility splays, • two connection cable route options into the substation, • indicative solar PV array. 9. The fence line around the indicative solar PV array would define the extent of the panels within the site, with a solar PV buildable area of 65.96 ha. The scheme proposes that the substation, occupying 0.37 ha, would be permanent, and that the grid connection would be provided separately by the District Network Operator. The scheme proposes a maximum export capacity of 49.9 MW.

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council The landscape assessment was based on the top of all PV modules and racks not exceeding 3.6m above the existing ground level, security fencing limited to 2.4m high, deer fencing 2m and security CCTV 3.5m. 10. SDC issued a screening opinion that the proposed development was not Environmental Impact Assessment development for the purposes of the EIA Regulations.8 Having considered all the evidence and seen the site and surrounds, I concur that the proposal is not EIA development. Statements of Common Ground 11. The appellant and SDC submitted a Statement of Common Ground (SoCG) dated 14 April 2025, which was amended on 28 April to include reference to non- designated heritage assets (SoCG1).9 At the Case Management Conference held on 12 May 2025 I requested an addendum to this statement to provide more details about consultation for the proposed amendments to the scheme, the appropriate planning balance in this case, and how National Planning Policy Framework (NPPF) paragraphs 160 and 155 should apply (SoCG2).10 Local and national policy 12. The development plan for the locality comprises the Sevenoaks Core Strategy Development Plan 2011 (CS), and the Sevenoaks Allocation and Development Management Plan 2015 (ADMP).

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council Appeal Decision APP/G2245/W/25/3359260 13. I have had regard to the NPPF and the Planning Practice Guidance (PPG). The NPPF states that the planning system should support the transition to net zero by 2050 and help to support renewable and low carbon energy and associated infrastructure. It also provides that planning decisions should contribute to and enhance the natural and local environment by, amongst other things, recognising the intrinsic character and beauty of the countryside. The PPG includes guidance about renewable and low carbon energy.11 14. Given that the capacity of the proposed solar farm in this appeal would be so close to the 50 MW threshold for a Nationally Significant Infrastructure Project (NSIP), I consider that Overarching National Policy Statement for Energy (EN-1) and National Policy Statement for Renewable Energy Infrastructure (EN-3) are material considerations in determining this appeal.12 The site and surrounds 15. The 99 ha appeal site lies to the south of Horton Kirby, which is designated as a service village in the CS. Field 3A separates the proposed solar arrays from residential development at Saxon Place, which comprises 74 dwellings.

Page 4 · Chunk 10

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council This field is outside the red line boundary for the appeal site but within the control of the appellant.13 The site is bounded to the north-east by Mussenden Lane and the M20 motorway lies to its south-west. Ancient Woodland is located to the south of the site on three sides of Field 5B. Footpath SD333 traverses Field 9 and joins Footpath SD169, which crosses over the M20 via a footbridge. SD333 also connects with Footpath SD156, which passes close to the western boundary of the appeal site and extends to Saxon Place. Listed buildings 16. Mussenden Farm Complex adjoins part of Field F3A. This comprises four grade II listed buildings; Mussenden Farmhouse, two barns and a granary. I am required by Section 66(1) of the Planning (Listed Buildings and Conservation Areas) Act 1990 to have special regard to the desirability of preserving the setting of a listed building. There is also a non-designated Oast House to the south-east of the farm complex. All these historic buildings have been converted to residential dwellings. Inquiry proceedings 17.

Page 4 · Chunk 11

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council I decided at the Inquiry that cross-examination would not be necessary for me to obtain all the information necessary to determine the appeal and so the event proceeded as focussed round table discussions. These dealt with the following matters that were identified in my Post-Case Management Conference Note: • Further information submitted by the appellant at the appeal stage • Green Belt • Character and appearance including cumulative effects • Agricultural land • Biodiversity • Renewable energy 11 The PPG includes reference to a speech by the Minister for Energy and Climate Change, the Rt Hon Gregory Barker MP, to the solar PV industry on 25 April 2013 and written ministerial statement (WMS) on Solar energy: protecting the local and global environment made on 25 March 2015. The latter notes that the use of BMV land would need to be justified by the most compelling evidence, but adds that proposals would need to be considered in the light of relevant material considerations. 12 EN-1 paragraphs 1.2.1 and 1.2.2. 13 CD2.1.15 and CD3.3. https://www.gov.uk/planning-inspectorate 4

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council Appeal Decision APP/G2245/W/25/3359260 • Planning balance and planning policy • Suggested planning conditions The parties were given time to comment on suggested planning conditions. The Inquiry was closed in writing on 27 June 2025. 18. The Department for Energy Security and Net Zero subsequently published the Solar Roadmap United Kingdom Powered by Solar, June 2025 (the Roadmap). The Ministerial Forward states that the Roadmap presents the final conclusions of the Solar Taskforce, setting out the steps Government and industry will take. It adds that “Publishing this Roadmap is just the beginning of our journey – and we will establish a joint Government and industry Solar Council to drive progress towards our ambitions”. The parties were given time to comment on the relevance of the Roadmap to this appeal.14 Main issues 19. The main issues in this appeal are: (a) The application of Green Belt policy. (b) The effect of the proposed development on the character and appearance of the area, including cumulative impact. (c) The effect on heritage assets. (d) The effect on agricultural land and food production. (e) The effect on biodiversity. (f) Renewable energy considerations.

Page 5 · Chunk 13

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council (g) Local and national planning policy and whether the benefits of the proposal would outweigh any harm. Reasons Green Belt 20. The appeal site is not near to a large built-up area. It does not contribute strongly to Green Belt purpose a), which is to check the unrestricted sprawl of large built-up areas. Green Belt purpose b) to prevent neighbouring towns merging into one another, and purpose d) concerning the preservation of the setting and special character of historic towns, are not relevant in the circumstances that apply in this case. The appeal site does not strongly contribute to any of Green Belt purposes a), b) or d). For the reasons set out later in this decision none of the policies relating to the areas or assets in NPPF footnote 7 provide a strong reason for refusing or restricting development.15 I find that the appeal site is grey belt land for the purposes of applying NPPF paragraph 155. 21. The proposed development would have a moderate adverse impact on Green Belt purpose c) regarding assisting in safeguarding the countryside from encroachment. However, no harm would arise to purpose e) regarding regeneration. Some 93% of the district is Green Belt.

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council The development of the part of the Green Belt land that comprises the appeal site would not affect the ability of all the remaining Green Belt across the area of the plan from serving all five of the Green Belt purposes in a meaningful way. I find that the proposed development would not fundamentally undermine the purposes (taken together) of the remaining Green Belt across the area of the plan. 14 ID13, ID14 and ID15. 15 Paragraph 4.3 SoCG2 at CD10.9. https://www.gov.uk/planning-inspectorate 5

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council Appeal Decision APP/G2245/W/25/3359260 22. As set out in paragraph 56 of this decision the proposed development would assist in meeting the need for renewable energy. There is a demonstrable unmet need for the type of development proposed. 23. The specific locational requirement for the proposed solar farm, in terms of an available grid connection, has implications for the accessibility of the site in this rural area. Access would be via rural lanes. But with the exception of construction and decommissioning periods the facility would not generate much traffic. Safe and suitable access could be secured by the imposition of appropriate planning conditions. Overall, I consider that the proposed solar farm would be in a sustainable location having regard to paragraphs 110 and 115 of the NPPF. 24. The Golden Rules as set out in NPPF paragraphs 156 - 157 do not apply in this case. I concur with the appellant and SDC that the appeal site is grey belt land. The proposal is not, therefore, inappropriate development in the Green Belt.

Page 6 · Chunk 17

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council The appeal scheme would result in no harm to the Green Belt.16 There is no conflict with CS Policy LO8 because the policy refers to development compatible with policies for protecting the Green Belt. NPPF paragraph 160 states that when located in the Green Belt, elements of many renewable energy projects will comprise inappropriate development. However, I agree with the appellant and SDC that paragraph 160 is not triggered in this case. The development is not regarded as inappropriate because parts a. b. and c. of NPPF paragraph 155 apply.17 Character and appearance 25. At the national level the site lies within National Character Area 119:North Downs, and at the County level in the North West Kent Landscape Character Area (LCA). The northern part of the appeal site lies within the Darenth Downs Landscape Character Type (LCT), which is characterised as a smooth, open arable landscape on chalk that is crossed by major transport routes. Its condition is assessed as poor, with moderate sensitivity and guidelines to restore ecological interest in arable areas and create new ecologically rich vegetative cover/woodland adjacent to the motorway corridor.

Page 6 · Chunk 18

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council The southern part of the site is within the Ash Downs LCT, a mix of grassland with extensive arable farmland, in good condition, with high sensitivity and guidelines to conserve the LCT. In the more recent Sevenoaks Landscape Character Assessment (2017) the site is identified within LCT 2:Downs and at a finer level within LCA 2b Eynsford and Horton Kirby Downs. Key characteristics of the latter include a gently undulating chalk landscape with a medium-large scale field pattern, and narrow winding lanes juxtaposed with the busy A20/M20. Guidelines include restoring the integrity of field boundaries and enhancing hedgerows. 26. The proposed solar panels, substation, inverters, batteries and access tracks would occupy 65.96 ha of land, rendering the appeal scheme a large-scale development that would, in terms of overall scale, be reasonably commensurate with the medium to large-scale arable landscape within which it would be sited. The field pattern would be maintained. However, the metal and glass panels of the solar arrays, along with their regular arrangement in long rows, together with inverters/batteries, would be out of keeping with the character of the area.

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council Appeal Decision APP/G2245/W/25/3359260 rural settlement context, and so the proposed development would introduce a discordant element into the local landscape. Mitigation planting would accord with ADMP Policy G1 concerning green infrastructure but would not ameliorate this harm to landscape receptors. 27. Turning to the visual effects of the proposal, the appellant acknowledges that the appeal scheme would have a major adverse effect for users of the PRoW at Viewpoint 5, and a moderate adverse effect at Viewpoint 4.18 The appeal scheme would have a negligible visual effect from other public vantage points. Some of the proposed hedgerow planting would obscure existing attractive views across the open countryside, such as along part of Footpath SD156 adjacent to the motorway. Planting here would also screen distant views towards the Mussenden Farm Complex.19 28. The appellant’s assessment does not consider the view from residential properties in Saxon Place. Some 22 of the dwellings in Saxon Place directly face the appeal site, at a distance that varies between 220m and 380m to the closest proposed PV arrays.

Page 7 · Chunk 22

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council The Landscape Institute’s Guidelines for Landscape and Visual Impact Assessment notes that visual receptors include people living in the area, and that residents at home are particularly susceptible to changes in visual amenity.20 I saw the view from the rear of some Saxon Place dwellings at my accompanied site visit. At the Inquiry I requested cross-sections through Field F3A to the proposed arrays/batteries so as to better appreciate the effect of the local topography on views and the likely effectiveness of screening.21 29. Views from these properties are private, not public views, but if included as a Viewpoint in a visual assessment, I consider that with high sensitivity and medium magnitude of effect the appeal scheme would have a major adverse effect for the following reasons. The cross-sections indicate the likelihood that solar panels would be visible in Fields F3C and F5A. Mitigation planting would help to soften this impact in time, as is evident from the year 15 predictions in the cross-sections, but would not eliminate the harm to the visual amenity of the area.

Page 7 · Chunk 23

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council It was also evident at my site visit that solar panels would be apparent on the upper slopes of Fields F5A and F5B in views towards the woodland on the horizon. I consider that the effect on the visual amenity of the area from properties in Saxon Place would be comparable to that which the appellant assessed for Viewpoint 5. 30. Local residents consider that the appellant should have undertaken a residential visual amenity assessment.22 The outlook from Saxon Place properties would be across a shallow valley that contains Field 3A, which is proposed Skylark Area 2. I was able to assess the relationship between residential properties in Saxon Place and the proposed development at my site visit. Some dwellings in Saxon Place would have a view of the proposed development from rear gardens and windows. It was also evident from visiting the lane outside the Mussenden Farm Complex that private views of some solar panels would also be likely from these dwellings. 31. However, given the separation distance, undulating topography and proposed landscaping, I consider that the solar farm would not have an overbearing or dominating effect on the outlook from nearby residential dwellings. The outlook 18 CD10.13C Appendix 14.

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council Appeal Decision APP/G2245/W/25/3359260 would not be so affected by the proposed solar farm as to give rise to an unacceptable adverse impact on the residential amenity of occupiers that would need to be avoided in the public interest. Noise is a matter that could be reasonably controlled by a planning condition to ensure that the scheme did not have an unacceptable impact. The proposal would comply with ADMP Policy EN7 concerning noise pollution. I am satisfied that the development would reasonably safeguard the amenities of the occupants of nearby properties and so would accord with ADMP Policy EN2. 32. Local residents are concerned about the cumulative impact of several solar farms in the locality.23 Gabrielspring Wood Solar Park, Horton Wood Solar Farm and the appeal site lie within LCA 2b. However, taken together these schemes would result in a low magnitude of change for the character of LCA 2b, which covers an extensive area of the North Downs. I concur with the appellant’s assessment that adverse cumulative effects on the landscape character of the area would be minor. 33.

Page 8 · Chunk 27

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council Gabrielspring Wood Solar Park, which is located on the opposite side of the M20 to the appeal site, was granted planning permission in April 2025. At its closest this solar park would be about 49m from the appeal site, but there is no intervisibility because of dense vegetation along both sides of the motorway. Some sequential views of the appeal scheme with Gabrielspring Wood Solar Park might be possible for those entering or leaving the appeal site via Footpath SD169 and the motorway footbridge, especially when trees were not in leaf. But these would be occasional given the distances between vantage points, as Viewpoint 9 indicates. 34. There is no network of PRoW between the appeal site and Horton Wood Solar Farm (476m from the appeal site and as yet unbuilt) and the lack of connectivity would limit any opportunities for sequential views for those travelling in the locality. Potential exists for some in combination views, for example from Viewpoint 10, but any views that took in parts of Horton Wood Solar Farm and parts of the appeal scheme would be at considerable distance and unlikely to be intrusive in the wide view of the rural landscape.

Page 8 · Chunk 28

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council I concur with the appellant’s assessment that adverse cumulative visual effects would be minor. A larger scheme is proposed some 1,154m from the appeal site (New Ash Green Solar). At the time of the Inquiry permission had not been granted for this scheme and so not much weight can be given to it. 35. I understand local anxiety about the likelihood of cumulative impacts from several solar farms in the wider locality. However, it was apparent at my site visits that the combination of separation distance, local topography and intervening vegetation are such that any adverse cumulative landscape or visual effects attributable to the appeal scheme would only have a minor effect. 36. The permanent substation and its access would, with appropriate landscaping, have a negligible effect on the character and appearance of the area. The level of landscape and visual harm from the remainder of the proposed development would not be permanent but would persist for 40 years and exceed what is regarded as long term.24 23 ID5. 24 GLVIA3 paragraph 5.51 refers to long term as ten to twenty-five years. https://www.gov.uk/planning-inspectorate 8

Page 9 · Chunk 29

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council Appeal Decision APP/G2245/W/25/3359260 37. The proposal would have an adverse effect on the landscape resource of moderate significance, and an initial adverse visual impact of major significance that would reduce with maturing landscaping to an adverse effect of moderate significance for the remainder of the duration of the solar farm. SDC’s opening statement to the Inquiry recorded that the landscape harm would be limited and that the effects of the proposed development on landscape accords with national and local policy and so is acceptable. Nevertheless, the harm to the character and appearance of the area that I have identified weighs against the proposal and should be given moderate weight in the planning balance. Heritage assets 38. Mussenden Farmhouse is listed as a 17th / 18th Century two-storey painted brick building. However, there is evidence that some parts of the building are older.25 The 18th Century barn to the north of the farmhouse, which is now known as The Stables, is adjacent to the lane. The 18th Century barn to south-east of the farmhouse is wrongly labelled as it lies to the west of the farmhouse and is now known as The Barn.

Page 9 · Chunk 30

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council The listed description for the 18th Century Granary is also misleading as it is located to the south-west of the farmhouse. The non-listed Oast House, with two roundels, lies to the south-east of the farmhouse. 39. As residential buildings these heritage assets now appear within individual residential plots. However, the grouping of the buildings provides for some understanding of the hierarchy of the buildings within the layout of the farm complex in views from the lane. The significance of these assets derives primarily from their physical fabric and grouping. The functional association between the buildings and the adjoining agricultural land has been severed. Nevertheless, the agricultural surrounds, of which the appeal site forms part, provide local context and an historical association that aids appreciation and understanding of the former functions of the buildings. In this respect the setting of the heritage assets contributes to their significance. 40. The nearest proposed solar panel arrays in Fields F3C and F3B would be about 180m from the Oast House, with the listed buildings further from the proposed development. The intervening Field F3A would remain in agricultural use with plots for skylarks.

Page 9 · Chunk 31

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council Solar panels in the wider context would cause a slight reduction in the ability to appreciate the role these historic buildings played in the agricultural history of the locality. This change in the local character, and the resultant harm, would be temporary and reversible. I find that the appeal scheme would result in a low level of less than substantial harm to the significance of the four listed buildings through a temporary change in the wider agricultural surroundings. 41. The unlisted Oast House is thought to date from the early 19th Century. There is evidence that it was owned and tenanted by the same people as the Mussenden Farm Complex. It now sits within a garden plot, but the roundels with cowls are a distinctive feature. The physical fabric of the building best demonstrates its architectural and historic interest. The agricultural surrounds hold some historic association, with the Oast House providing tangible evidence of hop-farming’s importance in the past to the local economy. Some of the fields within the appeal site may have contributed hops for the Oast House. However, the appeal site makes a minor contribution to the significance of the asset.

The housing estate at Saxon Place covers the site of an Anglo-Saxon burial ground that was excavated in the 1930s. An archaeological evaluation has determined that the burial ground does not extend into the appeal site. Kent County Council Archaeology reviewed this evaluation and considers that the impact of the development on the archaeological potential of the site could be adequately mitigated in accordance with ADMP Policy EN4.26 43. I have taken into account the group value of the heritage assets at the Mussenden Farm Complex and find that the overall less than substantial harm I have identified to the significance of each of the designated heritage assets should be weighed against the public benefits of the proposal in accordance with NPPF paragraph 215, and a balanced judgement made for the Oast House having regard to the scale of harm and the significance of the non-designated asset (NPPF paragraph 216). Agricultural land 44.

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council The appeal site comprises 76 ha of grade 2 agricultural land, 17 ha is classified as grade 3a, with 3 ha of grade 3b land. Therefore, 96.9% of the site is classified as BMV agricultural land. NPPF paragraph 187 b) provides that planning decisions should contribute to and enhance the natural and local environment by, amongst other things, recognising the economic and other benefits of BMV agricultural land. Footnote 65, albeit in a reference to plans, states that where significant development of agricultural land is demonstrated to be necessary, areas of poorer quality land should be preferred to those of a higher quality. EN-3 has similar provisions.27 The Written Ministerial Statement Solar and protecting our Food Security and Best and Most Versatile (BMV) Land, which was made on 15 May 2024, reflects current policy and guidance and does not introduce any new policy tests.28 45. Policy and guidance for BMV agricultural land do not mandate the consideration of alternatives or require a sequential test.

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council The appellant submitted evidence about land quality in the locality.29 I am satisfied that reasonable consideration has been given to using poorer quality land having regard to other constraints, such as fragmented landholdings, small fields and small woods in the locality. Given the requirements for a solar farm of this scale, including an available grid connection, I consider that it would be necessary to use agricultural land, and that land of poorer quality is not available. 46. The appellant’s intention is to graze sheep within the solar farm.30 There is local concern about the practicalities of grazing. However, the Roadmap provides that solar and farming in combination can provide further financial opportunities, food 26 CD8.16. 27 EN-3 paragraph 2.10.29 states that while land type should not be a predominating factor in determining the suitability of the site location applicants should, where possible, utilise suitable previously developed land, brownfield land, contaminated land and industrial land.

It adds that many solar projects are designed to enable continued livestock grazing. Notwithstanding the intention to graze livestock the proposal would result in a reduction in agricultural productivity from the appeal site for a period of 40 years. However, there is no convincing evidence that this loss of productivity, either solely or cumulatively with other solar farms, would have significant implications for food security.31 47. Subject to the imposition of appropriate planning conditions the solar farm could be decommissioned and restored with no permanent loss of agricultural land quality within the appeal site, except for the land required for the substation. Again, depending upon appropriate management, which could be the subject of a condition, soil quality and biodiversity could be enhanced by less intensive agricultural use over a 40-year period. 48. Taking all these matters into account, I consider that using 93 ha of BMV agricultural land for renewable energy generation would be justified in the circumstances that apply here.

Page 11 · Chunk 39

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council Nevertheless, taking the appeal site out of arable production for 40 years and replacing agricultural land with a substation would have some effect on agricultural productivity in the locality, albeit with negligible impact on food resilience and security considerations. Overall, I consider that the appeal scheme would result in an adverse effect of minor significance insofar as it would impact on agriculture but find no policy conflict in this regard. Biodiversity 49. The statutory 10% biodiversity net gain (BNG) requirement does not apply in this case. However, the appellant submits that the biodiversity net gain of 50.22% for habitat units and 39.93% for hedgerow units should be accorded substantial beneficial weight in the planning balance.32 Given that the benefits of the appeal scheme claimed by the appellant include this level of BNG, I consider that it would be necessary to impose a condition setting these levels of gain rather than the 10% proposed in the agreed suggested conditions. Biodiversity enhancements would include wildflower meadows and species rich grassland planting, along with bird and bat boxes.

Page 11 · Chunk 40

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council The imposition of conditions could also safeguard woodland, trees and hedgerows during construction and decommissioning. No works would be undertaken within 20m of the edge of woodland. Access for construction vehicles and any horizontal directional drilling could be strictly controlled to protect the Ancient Woodland. 50. SDC takes no issue with the appellant’s evidence about biodiversity, but local residents challenged some of these findings, particularly with respect to the effects on skylark territories. Kent County Council Ecological Advice Service does not dispute that the proposed enhancements of the solar farm would be likely to benefit nesting skylarks in the wider area. The Service also stressed the importance of monitoring the use of the solar farm by skylarks. However, it does not consider that the proposal would fully mitigate the loss of breeding skylark territories.33 The appeal scheme would result in an overall loss of between 6-8 skylark territories, which would be an adverse impact at the local level. However, Field 9 would be positively managed for conservation, with enhanced grassland, 31 CD10.11C Appendix 2 section 8. 32 CD3.5 and CD10.11B paragraphs 11.36 and 11.37.

The Roadmap cites a study by the Royal Society for the Protection of Birds and the University of Cambridge, which found that hectare for hectare solar farms in East Anglia contained nearly three times as many birds compared to surrounding arable land. 51. Notwithstanding the biodiversity benefits of the scheme, the net loss of skylark territories would be an adverse impact that weighs against the proposal. However, I concur with the appellant and SDC that the proposal would accord with national and local policy in respect of biodiversity.34 Overall, I consider that the biodiversity benefits of the scheme warrant moderate weight in favour of the proposal in the planning balance. Renewable energy 52. Appendix A to Mr Urbani’s Installed Capacity Note sets out indicative parameters for 117,442 solar panels for the buildable area of 65.96 ha (163 acres), with a density of 2.29 acres/MWdc. This scale of development would be consistent with the guidance in EN-3.35 However, it would result in some overplanting.36 The ratio for the indicative scheme is 1.52 MWdc/MEC (maximum export capacity).

Page 12 · Chunk 44

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council I have taken into account the justification for this degree of overplanting set out in section 6 of CD10.11C Appendix 3A. This provides that the 52% increase above the 49.9 MW MEC would comprise 13% for the difference between the output power defined under the Standard Test Conditions and actual meteorological conditions at the site, 27% for module degradation, and 12% for maximisation of the time the solar farm would export at the MEC. 53. A condition could ensure that the scheme did not breach the NSIP threshold of 50 MW. The overplanting would enable additional MW hours of renewable energy to be produced. The full extent of the development, including the likely degree of overplanting, has been assessed on a worst-case basis in determining this appeal. I am satisfied that the likely level of overplanting would be reasonable in the circumstances that apply to this site, having taken into account the Ross judgment about interpreting and applying EN-3.37 On the basis of the indicative scheme the proposed development would power 22,945 homes.38 The appellant has a grid connection offer with a date of 31 October 2030 and so the scheme could form part of the Clean Power 2030 Action Plan for solar capacity.39 54.

Page 12 · Chunk 45

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council There is local concern about the absence of any provision for community benefits. The Government published a working paper on 21 May 2025 seeking views on introducing a mandatory community benefit fund scheme for low carbon energy infrastructure including solar. A voluntary community benefits protocol and guidance for solar is to be published later this year.40 In the absence at this stage of a specific policy requirement for the provision of community benefits, the fact that the appeal scheme makes no such provision does not weigh against the proposal. The appellant is negotiating a voluntary scheme with the local 34 CD4.1 paragraph 99. 35 Paragraph 2.10.17 of EN-3 provides that for a 50 MW scheme the site would range from 125 to 200 acres, contain 100,000 to 150,000 solar panels, and have a density of 2 to 4 acre/MWdc. 36 Where the ratio of MWdc from the panels to the MWac of inverters is greater than 1. 37 Ross v SSHCLG [2025] EWHC 1183 (Admin) at CD7.45. 38 CD10.11C Appendix 3A page 10. 39 CD5.25 and CD10.11C Appendix 3B.

NPPF paragraph 168 does not require the overall need for renewable energy to be demonstrated and requires that significant weight is given to the benefits associated with renewable energy generation and the proposal’s contribution to a net zero future. EN-3 provides that the Government is committed to sustained growth in solar capacity as a key part of its strategy for low-cost decarbonisation of the energy sector. It adds that solar also has an important role in delivering the Government’s goals for greater energy independence and refers to Powering Up Britain: Energy Security Plan.42 The proposal would make a cumulative contribution to meeting the target set out in the Climate Change Act 2008.43 It also gains support from the UK Government Solar Strategy 2014 44, the Net Zero Strategy 45 and the British Energy Security Strategy 46. The Solar Roadmap refers to the Clean Power Action Plan call for the rapid acceleration of solar deployment, from over 18 GW at present to 45-47 GW by 2030. 56.

Page 13 · Chunk 47

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council Given the benefits of the appeal scheme to the reduction of carbon emissions and towards energy security considerations, along with national support for the generation of renewable energy, as outlined in the preceding paragraph, I consider that these benefits of the proposed solar farm attract substantial weight in the planning balance. The scheme would also have economic benefits in providing employment and contributing to the local and wider economy, which should attract some slight weight. Other issues raised by third parties 57. Access to the site would use some narrow rural lanes. However, the highways evidence indicates that the imposition of conditions could mitigate adverse travel impacts, and I find no conflict with ADMP Policy T1. The appeal scheme includes siting for a drainage infiltration trench and a detailed sustainable surface water drainage scheme could be required by a planning condition. 58. I am satisfied that the technical evidence submitted is sufficient to assess the likely effects of glint and glare from solar panels. With the proposed landscaping the solar farm would have a low impact on drivers using the local road network and those living in the area.

Page 13 · Chunk 48

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council The likelihood of unacceptable glint and glare does not weigh against the proposal. 59.

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council Appeal Decision APP/G2245/W/25/3359260 greater the weight should be). I have taken this into account in awarding weight to the harm I have identified to the designated assets. This harm must be given considerable importance and weight in the balancing exercise required by NPPF paragraph 215. Taking all the above into account, I consider that the overall less than substantial harm to the significance of designated heritage assets is outweighed by the public benefits of the proposed development that are attributable to the generation of renewable energy, biodiversity net gain and economic benefits. In the balanced judgement required by NPPF paragraph 216 for the non-designated Oast House, I consider that the low level of harm to this heritage asset would not weigh much against the proposal. 61. Turning to the overall balancing exercise, I consider that the harm to the character and appearance of the area, harm to heritage assets, along with minor harm to agriculture, would be outweighed by the benefits of renewable energy generation, biodiversity net gain and the economic benefits that would result from the appeal scheme. 62. CS Policy SP1 requires that heritage assets and their settings will be protected and enhanced.

Page 14 · Chunk 51

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council The appeal scheme would be at odds with this policy because the less than substantial harm I have identified would not protect the assets. However, this policy does not fully accord with the provisions for balancing harm and benefits in the NPPF. The proposal would also conflict with ADMP Policy EN5 because it would not conserve the character of the landscape, but it would secure some landscape enhancements in accordance with the policy. The weight given to this policy conflict should also reflect the fact that EN-3 states that development of this scale will inevitably have impacts, particularly if sited in rural areas, and that potential solar farm sites are largely in rural areas.47 I find no conflict with provisions in Policy LO8 that seek to ensure that all development conserves and enhances local landscape character because the policy adds provision for appropriate mitigation where damage to local character cannot be avoided. 63. Other development plan policies pull strongly in favour of the proposal. The scheme accords with the underlying aims of CS Policy SP2 because it would contribute to the goal of achieving zero carbon development as soon as possible.

Page 14 · Chunk 52

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council It also benefits from CS Policy SP11 because of the BNG gain and because it takes advantage of opportunities for the enhancement of biodiversity. I consider that the appeal scheme complies with the development plan taken as a whole. 64. SDC considers that NPPF paragraph 11.d)ii is in play here. The basis for this view appears to be an alleged inconsistency of ADMP heritage Policy EN4 with the NPPF.48 However, I read Policy EN4 as a positive policy. It states that proposals that affect a heritage asset, or its setting, will be permitted where the development conserves or enhances the character, appearance and setting of the asset. The policy does not rule out proposals that would result in some harm to heritage assets, but where that harm would be outweighed by other benefits. On this reading there would be no conflict with the provisions of the NPPF. 65. I find that the proposal is in accordance with an up-to-date development plan, that paragraph 11(c) of the NPPF applies, and that the proposal should be approved without delay. 47 EN-3 paragraphs 2.10.17 and 2.10.36. 48 Paragraph 4.2 SoCG2 at CD10.9 and paragraphs 7.32-7.34 CD10.7. https://www.gov.uk/planning-inspectorate 14

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council Appeal Decision APP/G2245/W/25/3359260 66. However, if I am wrong about the consistency of ADMP Policy EN4 with the NPPF, and if this is sufficient to render the policies that are most important for determining the appeal out-of-date, then NPPF paragraph 11.d) would apply. In those circumstances, I find that the application of NPPF policies do not provide a strong reason for refusal, and that the adverse impacts of the appeal scheme would not significantly and demonstrably outweigh the benefits, when assessed against the policies in the NPPF taken as a whole, and so planning permission should be granted. Other matters 67. I have taken into account all other matters raised in evidence, but have found nothing to outweigh the main considerations that lead to my conclusion. Conditions 68. I have given careful consideration to the thoughtful representations about suggested planning conditions.49 The wording of some of the suggested conditions would need to be amended to ensure that they are necessary, relevant to planning and to the proposed development, enforceable, precise and reasonable in all other respects. The following condition numbers refer to the numbering in the attached Schedule of Conditions. 69.

Page 15 · Chunk 54

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council The standard commencement condition would apply (Condition 1). Conditions would need to specify the duration for the Development and require restoration on decommissioning, for the Site and for any parts of the Site where export of electricity ceased before the end of the 40-year period (Conditions 2, 3, 4 and 5). Approval of a decommissioning statement before development commenced would not be necessary because decommissioning plans should have regard to relevant policy and practice at that time. Site restoration could then take advantage of up- to-date evidence about the decommissioning of other solar farms. 70. A Construction Management Plan would be required to safeguard the amenity of the area, but this should include provision for liaison with the local community, provision of contact details for the construction site manager, and a scheme to control traffic routing to and from the Site (Condition 6). A highway condition survey and provision for any remediation works would be necessary (Condition 7). However, this would not need to include Scratchers Lane, which is about 6.5m wide, whereas Three Gates Road and Gabriel Spring Road East are much narrower.

Page 15 · Chunk 55

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council Access details would need to be approved for highway safety reasons (Conditions 31 and 32). 71. A landscape scheme, provision for planting and controls for lighting would be necessary in the interests of the appearance of the area (Conditions 8, 15 and 19). There is a discrepancy in the suggested conditions for replacement planting with references to both a 5 year and 10 year period.50 I am satisfied that 5 years would be appropriate here to secure the establishment of planting. Provisions for archaeological interest in the Site and interpretation of heritage assets would provide historical context for the Development (Conditions 9, 10 and 11). For safety reasons pipelines in the locality would need to be protected (Condition 12), and any land contamination resolved (Condition 13).

Management of PRoW for the duration of the Development would provide for safe public access (Condition 16). 72. A landscape and ecological management plan (Condition 17), biodiversity net gain plan (Condition 23), biodiversity enhancement plan (Condition 27) and ecological decommissioning plan (Condition 26), would all be necessary in the interests of nature conservation and wildlife management. In accordance with ADMP Policy EN1 a strategy would assist in designing out crime (Condition 18). There is no evidence to indicate that more restrictive hours for construction and deliveries than the normal hours agreed by SDC and the appellant should apply in this case (Condition 20). 73. It would be necessary to define the permission and ensure that the development was carried out in accordance with the approved plans (Condition 21). Given that much of the detail about the scheme is illustrative, a Condition would be required to enable approval to be granted for relevant details of the Development (Condition 22).

Page 16 · Chunk 57

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council The installed export capacity for the Development would need to be specified to ensure that the Development did not exceed the threshold for a NSIP (Condition 24). The scheme proposes grazing and doing so would require a management plan (Condition 25). 74. NPPF paragraph 198 provides that potential adverse impacts resulting from noise from new development should be mitigated and reduced to a minimum. This accords with a policy aim of the Noise Policy Statement for England, which is to mitigate and minimise adverse impacts on health and the quality of life. I queried at the Inquiry how imposing a noise limit of background plus 5dB would square with this policy given the relatively high background levels that were attributed at the Inquiry to the proximity of the M20 motorway. Alternative versions for the suggested noise condition were subsequently included in ID7. I consider that it would be reasonable in the circumstances that apply here to set a noise limit for the solar farm that did not significantly add to the already high background levels.

Page 16 · Chunk 58

Chimmens Solar Farm, Land at Mussenden Lane, Horton Kirby, Kent , DA3 8NX — Sevenoaks District Council The predicted levels in Table 8 of CD1.15 show that the predicted rating level of noise from the development would not exceed the background sound levels at any of the residential properties, at any time.51 It would not be unduly onerous for the scheme to mitigate noise levels so as not to exceed background levels, rather than the background plus 5 dB advocated by the appellant (Condition 28). 75. Given the risk of fire, a management plan would be necessary for the BESS. This would need to include details of battery units design and testing, a fire water management plan and vegetation control (Condition 29). A soil management plan would assist in the effective restoration for agricultural use on decommissioning (Condition 30). 76. There is clear justification for the imposition of the conditions that are required to be discharged before commencement of development. The appellant has agreed to these in the suggested conditions submitted to the Inquiry. 77.

Main issues and findings

Living conditions
Against appellant
¶22

The proposed development would introduce a discordant element into the local landscape, and the metal and glass panels of the solar arrays would be out of keeping with the character of the area.

Heritage impact
Against appellant
¶40

The proposed solar farm would result in a low level of less than substantial harm to the significance of the four listed buildings through a temporary change in the wider agricultural surroundings.

Agricultural land
For appellant
¶45

Using 93 ha of BMV agricultural land for renewable energy generation would be justified in the circumstances that apply here, and the proposal would result in an adverse effect of minor significance insofar as it would impact on agriculture.

Other
Against appellant
¶50

The appeal scheme would result in an overall loss of between 6-8 skylark territories, which would be an adverse impact at the local level, but the biodiversity benefits of the scheme warrant moderate weight in favour of the proposal in the planning balance.
