South Wales Church Solar — Church in Wales, Llandaff & Governance 2026

The Church in Wales context

The Church in Wales is the autonomous Anglican province covering the historic dioceses of Wales — disestablished from the Church of England in 1920. It operates under its own constitution, with its own Bench of Bishops, governing body and faculty jurisdiction framework.

For PCCs in South Wales considering solar, the constitutional and procedural framework is different from English practice. The Church in Wales does not use the Care of Churches Measure 2018 (English legislation) — instead, the Church in Wales Constitution governs faculty applications, and the Diocesan Advisory Committees operate under that constitution.

South Wales is covered by three Church in Wales dioceses:

• Diocese of Llandaff — most of Glamorgan including Cardiff, Bridgend, Vale of Glamorgan, Rhondda Cynon Taf
• Diocese of Monmouth — Newport, Monmouthshire, Caerphilly, Blaenau Gwent
• Diocese of Swansea and Brecon — Swansea, Neath Port Talbot, Powys

Church in Wales versus Church of England: what changes for solar?

The headline answer for most parishes: the practical process is functionally similar to England, but the legal framework is different and some specific elements diverge in important ways.

Aspect	Church of England	Church in Wales
Governing legislation	Care of Churches Measure 2018	Church in Wales Constitution
Faculty authority	Chancellor of the Diocese	Chancellor of the Diocese
National heritage body	Historic England	Cadw (Welsh Government)
Listed building category	Grade I / Grade II* / Grade II	Grade I / Grade II* / Grade II (same categories, different authority)
Listed building consent	Part of faculty process	Cadw involvement for higher-listed buildings
National amenity societies	SPAB, Victorian Society, etc.	Same societies operate in Wales
Net zero framework	Church of England Net Zero 2030	Church in Wales Net Zero 2030 (separate, aligned)

The most important practical difference is Cadw. In Wales, Cadw is the Welsh Government historic environment service — the equivalent of Historic England, but operating under Welsh Government authority and Welsh legislative framework (Planning (Listed Buildings and Conservation Areas) Act 1990 as amended by Welsh legislation). For Grade I and Grade II* Church in Wales buildings, Cadw consultation follows a similar path to Historic England consultation in England.

Welsh Planning Policy differs in one key way: Technical Advice Note 8 (TAN 8) covering renewable energy in Wales has a generally supportive policy framework for community renewable energy. Wales has ambitious renewable energy targets under Future Wales (the National Plan 2040), and the planning framework for community building solar is broadly enabling.

Llandaff DAC route

The Llandaff DAC has been progressively constructive on parish solar since 2020. The diocese has visible environmental officer support and the DAC has approved a steady stream of well-designed parish solar applications.

Common Llandaff DAC conditions on listed-building solar applications:

• Black-on-black panel specification on listed buildings
• Reversible fixings with detailed documentation
• For coastal Vale of Glamorgan parishes: corrosion-resistant specification
• Less-visible roof slopes preferred over principal elevations
• Detailed visual impact assessment for Grade I and II* parishes

The Church in Wales faculty process is functionally similar to English practice. Engagement timelines are typically comparable: allow 12–18 weeks for a straightforward Grade II application and 20–28 weeks for a Grade I building requiring Cadw consultation.

The Church in Wales Representative Body

The Church in Wales Representative Body is the holding body for the property, investments and assets of the Church in Wales — the equivalent of the Church Commissioners in England. The Representative Body runs capital grant programmes for parish buildings, and environmental improvement grants are an active part of the programme since 2022.

For Llandaff, Monmouth and Swansea & Brecon parishes, the Representative Body grant programme is the closest Welsh equivalent to Buildings for Mission. The programme operates on a quarterly application cycle; contact the provincial environmental officer for current eligibility criteria and amounts.

The South Wales context

South Wales parishes face a particular pattern of opportunities and constraints:

Strong: Excellent solar yields by UK standards, particularly along the coastal strip. Active diocesan environmental commitment across all three South Wales dioceses. Strong Welsh Government policy support for community energy. Mature industrial electrical contractor base from the region’s steel and energy heritage.

Constrained: Valley parishes face some winter cloud and terrain shading from surrounding hills. Listed-building constraints are significant — South Wales has a high concentration of medieval and Victorian parishes under Cadw protection. Some former coal and steel communities face capital-raising constraints relative to wealthier commuter-belt areas.

The yield context

South Wales yields:

• Cardiff / Vale of Glamorgan: ~940–990 kWh/kWp
• Bridgend / Llanelli coastal: ~950–1,000 kWh/kWp
• Swansea / Gower: ~960–1,010 kWh/kWp (open coastal exposure, outstanding yield)
• South Wales Valleys (Rhondda, Cynon, Taff): ~880–940 kWh/kWp (some valley shading reduces yield vs coastal)
• Brecon / Powys: ~900–950 kWh/kWp

The South Wales coastal strip — Cardiff Bay, the Vale of Glamorgan, Gower — has some of the better UK solar yields outside southern England. Swansea’s south-facing coastal position produces yields comparable to Hampshire and Dorset.

Capital schemes

• Church in Wales Representative Body — capital grants programme with environmental allocations for all three South Wales dioceses
• Llandaff Diocesan Board of Finance — diocesan capital scheme for Llandaff parishes
• Welsh Government — Local Energy Schemes — grants for community energy projects including parish buildings; administered through Natural Resources Wales (NRW) and Welsh Local Energy Service (WLES)
• Welsh Government — Community Investment Fund — capital funding for community buildings with energy improvement elements; Valleys communities have historically had good access to this route
• Buildings for Mission — available only to Church in Wales parishes with specific approval; the Church in Wales and Church of England maintain reciprocal access to national programmes; confirm eligibility with the provincial environmental officer
• Listed Places of Worship VAT Grant Scheme — UK-wide including Wales; applies to all Cadw-listed Grade II, II* and Grade I Church in Wales churches

Grant stacking for South Wales parishes

For a 20 kW installation on a Llandaff Diocese Grade II Victorian parish church and unlisted hall in Cardiff’s western suburbs:

Grant source	Amount	Basis
Church in Wales Rep Body	£9,000	Provincial environmental grant
Llandaff Diocesan capital	£5,500	Diocesan environmental allocation
Welsh Government Local Energy	£4,000	Community energy grant
Listed Places of Worship VAT	£3,333	20% VAT on listed church portion
Parish reserves	£3,167	Balance from PCC capital fund
Total project cost	£25,000	20 kW, church + hall
Net to PCC	£3,167	13% of capex

The Welsh Government Local Energy Scheme adds a distinctive layer to the South Wales grant stack that has no direct equivalent in England. Parishes in the Valleys and coastal communities — particularly those in communities designated as priority areas under Welsh Government regeneration programmes — may access additional Welsh-specific funding beyond what is listed above. We map all applicable routes as part of our standard feasibility assessment.

Worked example — a Cardiff Vale of Glamorgan parish

The building: An 1890s Grade II listed Victorian church in Penarth (Vale of Glamorgan) with a 1990s unlisted community hall. Sunday congregation of 65. Hall used five days per week as a community hub. Annual electricity bill: £8,200.

The system: 22 kW — 10 kW black-on-black on the chancel south slope (listed church, Llandaff DAC faculty, Cadw notified: “no objection”) and 12 kW standard commercial panels on the hall flat roof.

Coastal specification: Penarth is within 500m of the Bristol Channel — full C4 coastal specification applied to all metal components.

Consent: Llandaff DAC faculty granted in 18 weeks (Cadw notification added 4 weeks to the standard timeline; their response was supportive).

Grant stack: Church in Wales Rep Body £8,000 + Llandaff Diocesan £5,000 + Welsh Government Local Energy £3,500 + LPW VAT £3,500 = £20,000 grants. Gross capex: £24,000. Net to PCC: £4,000.

Year 1 performance: Generation 21,600 kWh, self-consumption 73% (active daily hall use), annual saving: £5,200. Simple payback on net cost: 0.8 years. Payback on gross capex: 4.6 years.

What makes South Wales church solar distinctive

The Gower Peninsula — Gower is an Area of Outstanding Natural Beauty with enhanced landscape sensitivity. Solar applications for Gower parishes require additional planning authority consultation with the City and County of Swansea’s AONB planning team. Roof-mounted installations on church buildings within the AONB are generally supported where heritage design conditions are met, but the consultation adds 4–6 weeks to the timeline.

Former industrial communities — Parishes in former coal and steel communities (Rhondda, Merthyr Tydfil, Blaenau Gwent, Port Talbot adjacent) sometimes have buildings with complex ownership and condition issues — asbestos roofing, structural concerns from subsidence, or deferred maintenance. A structural survey of the roof before committing to solar is standard practice in these communities. We include this as part of our feasibility process.

Welsh language engagement — Llandaff and Swansea & Brecon dioceses have Welsh-language congregations. The Church in Wales produces faculty guidance in both languages. Where a parish community is predominantly Welsh-speaking, engagement with the diocesan environmental officer in Welsh is supported.

Frequently asked questions — South Wales parishes

Is Buildings for Mission available to Church in Wales parishes? The Church in Wales and Church of England maintain reciprocal programme access arrangements, but eligibility for specific programmes varies. Buildings for Mission in its standard CofE form is primarily for Church of England parishes. The Church in Wales Representative Body capital programme is the primary equivalent. We confirm current access to BfM as part of every South Wales feasibility — in some recent rounds, Church in Wales parishes have successfully applied via a joint CofE/CiW route.

How does Cadw consultation differ from Historic England consultation? Cadw operates under Welsh Government authority and Welsh legislative framework, but in practice the consultation process for solar applications is similar to Historic England in England. Cadw will assess the same core questions: heritage impact on the listed building, reversibility, impact on the setting. The key operational difference is response timelines — Cadw’s statutory consultation window is 21 days for listed building matters, though complex applications can take longer. Pre-application contact with Cadw’s regional inspector is strongly advised for Grade I applications.

Can a Valleys parish access Welsh regeneration funding as well as church grants? Yes. South Wales Valleys parishes sit within areas designated for Welsh Government regeneration support, and this creates access to funding routes that don’t exist in most English regions. The Community Investment Fund, Shared Prosperity Fund Wales allocations, and specific Valleys Task Force programmes have all supported community building energy projects. Eligibility depends on the specific programme criteria in the year of application — we check all current Welsh funding routes as part of our feasibility.
