Church Solar in Wiltshire — Salisbury Diocese 2026 Guide

The Salisbury Diocese context

The Diocese of Salisbury covers Wiltshire (excluding Swindon, which falls under Bristol Diocese), most of Dorset and a small part of Hampshire. Salisbury Cathedral is one of the architectural treasures of medieval England and the diocese maintains a strong heritage tradition — many of its parishes are Grade I or Grade II* listed medieval foundations.

Salisbury Diocese has also been one of England’s more progressive on environmental matters: the diocese committed early to the Church of England’s net zero by 2030 target, and the diocesan environmental officer has been nationally influential in developing the CofE’s approach to parish sustainability.

Salisbury DAC route

The Salisbury DAC has been constructively engaged with parish solar since 2019 — among the earlier southern English DACs to develop a consistent positive framework. The DAC has approved a steady stream of well-designed parish solar applications across both Wiltshire and Dorset.

Common Salisbury DAC conditions on listed-building solar applications:

• Black-on-black panel specification
• Reversible fixings with detailed documentation
• For Grade I and II* parishes: detailed visual impact assessment from agreed viewpoints, often including key approach roads, footpaths, and long-distance views from downland
• Less-visible roof slopes preferred over principal elevations
• For Cranborne Chase AONB, North Wessex Downs AONB and Stonehenge World Heritage Setting locations: enhanced landscape and heritage assessment

For unlisted parish halls and vicarages, faculty is typically a faculty-not-required confirmation — a straightforward route.

Salisbury as a pioneer diocese

Salisbury Diocese’s early commitment to parish-level solar has created meaningful practical advantages for PCCs:

Established precedent: The DAC has now processed several hundred solar applications across the diocese’s 540+ parishes. This institutional familiarity means that well-prepared applications from heritage specialists are processed efficiently — the architectural advisor has deep experience with all the building types the diocese contains.

Developed diocesan grant programme: The Salisbury Diocesan Board of Finance has run a dedicated environmental grant programme longer than most comparable dioceses. This means the application process is well-defined, the criteria are clear, and PCCs can plan grant applications with confidence in the funding cycle.

Environmental officer network: The diocesan environmental officer is well-networked nationally — Salisbury has contributed to the development of the CofE’s national guidance on parish solar, which means the local officer is attuned to emerging best practice.

The Cranborne Chase and North Wessex Downs AONBs

Wiltshire contains two Areas of Outstanding Natural Beauty that create enhanced landscape sensitivity for solar applications:

Cranborne Chase and West Wiltshire Downs AONB: Covers the chalk downland of south Wiltshire and north Dorset, including many ancient settlements with Saxon and Norman church foundations. AONB planning policy requires that development conserves and enhances natural beauty — roof-mounted solar on community buildings is generally supportable where the visual impact is managed. The AONB partnership planning guidance is a useful reference document for faculty applications in the Chase.

North Wessex Downs AONB: Covers the northern Wiltshire downland including Avebury, Marlborough and the Savernake Forest fringe. Similar to Cranborne Chase, AONB policy supports community-building solar where heritage and landscape conditions are met.

For parishes in either AONB, allow 4–6 additional weeks in the consent timeline for AONB authority consultation. The Salisbury DAC is experienced in managing this consultation and typically runs it concurrently with Historic England notification where applicable.

The Stonehenge World Heritage Setting

Stonehenge and Avebury World Heritage Site is one of only four UNESCO designations in England. The WHS buffer zone covers a significant area of north Wiltshire, including parishes around Amesbury, Shrewton, Pewsey and the Vale of Pewsey.

For parishes within the WHS buffer zone, solar applications require:

• A Heritage Impact Assessment referencing the WHS Outstanding Universal Value Statement
• Pre-application consultation with Wiltshire Council’s WHS conservation team
• Assessment of visual impact from WHS viewpoints (including the WHS Management Plan’s key viewpoints list)

This is not a prohibition on solar — WHS buffer zone applications have succeeded elsewhere in England. But the documentation requirement is more substantial than for a standard AONB or Conservation Area application. We include WHS setting guidance in our feasibility for any parish within the buffer zone boundary.

The yield context

Wiltshire and Dorset benefit from strong south-of-England solar yields:

• South Wiltshire / Salisbury / Wilton: ~950–1,000 kWh/kWp
• Central Wiltshire (Melksham, Devizes, Marlborough): ~940–990 kWh/kWp
• North Wiltshire / Cotswolds fringe (Malmesbury, Chippenham): ~930–980 kWh/kWp
• Dorset coast (Bournemouth area, Weymouth, Swanage): ~970–1,020 kWh/kWp
• Dorset AONB rural: ~950–990 kWh/kWp

For a typical 15 kW parish system, annual yield of 14,500–15,500 kWh is realistic across the diocese — among the strongest rural UK figures.

Capital schemes

• Salisbury Diocesan Board of Finance — one of the more developed diocesan environmental grant programmes; active since 2019 with clear application criteria
• Buildings for Mission — Church of England national programme; Salisbury Diocese has a strong BfM award track record reflecting early engagement with the programme
• Wiltshire Council — climate emergency response community building grants
• Dorset Council — periodic community building grant rounds
• Listed Places of Worship VAT Grant Scheme — UK-wide; applies to the high proportion of Grade I and II* Wiltshire and Dorset medieval churches

Grant stacking for Salisbury Diocese parishes

For a 15 kW installation on a Grade II medieval Wiltshire village church and unlisted parish hall:

Grant source	Amount	Basis
Buildings for Mission	£10,000	National programme grant
Salisbury Diocesan capital	£6,000	Environmental programme grant
Listed Places of Worship VAT	£3,333	20% VAT on listed building works
Parish reserves	£2,167	Balance from PCC capital fund
Total project cost	£21,500	15 kW, church + hall
Net to PCC	£2,167	10% of capex

Salisbury Diocese parishes often have significant historic endowments from wealthy medieval wool merchants and later agricultural benefactors. This means parish reserves are frequently available for the balance, making 90–95% grant coverage achievable in well-endowed rural parishes.

Worked example — a Cranborne Chase AONB parish

The building: A 12th-century Grade II listed flint-and-stone parish church on the Cranborne Chase in south Wiltshire, with a 1980s unlisted village hall. Sunday congregation of 35. Hall used twice weekly. Annual electricity bill: £3,400.

The system: 10 kW — 5 kW black-on-black in-roof on the chancel south slope (listed church, facing away from the public approach road and Chase downland viewpoints) and 5 kW on the hall south slope.

AONB process: Salisbury DAC consultation ran concurrently with the Cranborne Chase AONB partnership letter exchange. AONB response: “supportive — slope selection avoids principal open-downland views, black-on-black specification appropriate.” Faculty granted in 16 weeks.

Grant stack: Salisbury Diocesan capital £4,500 + Buildings for Mission £6,500 + LPW VAT £2,000 = £13,000 grants. Gross capex: £15,000. Net to PCC: £2,000.

Year 1 performance: Generation 9,700 kWh, self-consumption 48%, annual saving: £2,100. Simple payback on net cost: 1.0 year. Payback on gross capex: 7.1 years.

Typical Salisbury Diocese parish profiles

• Adjacent unlisted hall (often 1970s–90s build)
• Vicarage on adjacent site
• Typical project: 20–30 kW parish-wide, ~£30,000–£45,000 gross, £5,000–£10,000 net after grants, £4,500–£6,500 annual saving, 7–10 years payback

Frequently asked questions — Salisbury Diocese parishes

Does the Stonehenge World Heritage Setting affect solar applications for parishes near Amesbury? Yes — parishes within the WHS buffer zone require a Heritage Impact Assessment and pre-application consultation with Wiltshire Council’s WHS heritage team. This typically adds 6–8 weeks to the consent timeline. However, the WHS setting does not prohibit solar. The key is demonstrating that the proposed installation has no adverse impact on the Outstanding Universal Value of the WHS — for a roof-mounted system on a Grade II church well within an existing settlement, this can typically be demonstrated. The Salisbury DAC is experienced in WHS buffer zone applications and has approved well-prepared projects in this setting.

Is Salisbury Diocese’s diocesan grant programme open on a rolling basis? The Salisbury Diocesan Board of Finance environmental grant programme operates on a quarterly application cycle. Applications for the strongest combined outcome should be timed so that the diocesan application and the Buildings for Mission application are submitted in the same quarter. The diocesan environmental officer can advise on current cycle timing and eligibility criteria when you make initial contact.

Our rural Dorset parish is in the Cranborne Chase AONB — does this make consent significantly harder? No — but it makes preparation more important. The AONB planning authority is a statutory consultee, and their response carries weight with the faculty authority. An application that has anticipated and addressed the AONB’s landscape character concerns — through slope selection, panel specification, and referencing the AONB Management Plan — typically receives a positive or neutral AONB response. An application that hasn’t thought through the landscape impact may face an adverse AONB comment that complicates the faculty decision. We address AONB sensitivity as a core element of our design process for all Chase parishes.
