18 kW Solar on Grade II Cheshire Parish Church

The parish

A 1860s Anglican parish church in rural Cheshire, Grade II listed, serving an active rural congregation of 60–80 Sunday worshippers plus a busy weekday hall programme. The church sits adjacent to an unlisted post-war parish hall used by the local primary school for assemblies, a Tuesday playgroup, weekly fitness classes, and weekend hires. The parish is part of a multi-church benefice in the Diocese of Chester.

The PCC had committed to working toward the diocesan Net Zero pathway and had already implemented LED lighting and a renewable electricity tariff switch in 2022. By 2023 the next intervention on the parish’s pathway was clearly going to be on-site generation, and the PCC began conversations about solar.

The scoping conversation

Initial PCC enquiry came via the churchwarden in February 2024 following a diocesan environment meeting. The PCC’s primary concerns at first conversation:

• Faculty jurisdiction — they had heard the process was complex
• Heritage impact — Grade II listed, with a prominent location at the village centre
• Capital cost — the parish operated a £4,500 annual deficit and had limited reserves
• Grant funding — they had heard Buildings for Mission existed but didn’t know how to access it
• Self-consumption — the church was Sunday-only and the PCC was worried about wasted generation

Initial desk feasibility (completed in 7 working days, free) addressed all five concerns:

• Faculty experience reassurance — we’d delivered nine successful faculty applications in the Diocese of Chester since 2018
• Heritage design — proposed black-on-black panels on chancel south slope (less visible than nave south slope from the village centre)
• Capital cost — indicative £20,000–£25,000 for an 18 kW system covering both the church and the hall
• Grant strategy — Buildings for Mission targeted at 65–75% of capex, plus Listed Places of Worship VAT scheme
• Self-consumption — combined church + hall design lifted self-consumption to 65–70% versus 30–35% for church-only

The faculty pathway

PCC voted in April 2024 to proceed. We commissioned a structural survey in May, confirming the church chancel south slope had adequate load capacity for a 6 kW array (10 panels) with reversible non-penetrative clamp fixings on the existing slate roof, and the hall main roof had capacity for the remaining 12 kW (18 panels) with standard commercial fixings.

Faculty application package prepared June 2024:

• Statement of Significance (1,200 words, drawing on the 2022 quinquennial)
• Statement of Needs (900 words, emphasising the diocesan Net Zero alignment and the parish’s hall outreach programme)
• Detailed drawings showing panel locations on chancel south slope (lych-gate elevation hidden) and hall main roof
• Conservation impact assessment, with black-on-black panel specification and in-roof flush mounting on the chancel
• Engagement with the diocesan architect at design stage; her supportive letter included with submission

DAC consultation July 2024 — recommended with conditions (specifying black-on-black panels, non-penetrative fixings, and removal plan kept with church inventory). Public notice period August 2024 — no objections received. Faculty granted by the Chancellor of the Diocese of Chester on 11 September 2024, eleven weeks after submission.

The grant funding

Buildings for Mission application drafted in parallel with the faculty application. The diocesan Net Zero Officer was supportive and provided the diocesan endorsement letter. Application submitted to the national Buildings for Mission fund August 2024.

Award notified November 2024: £14,000 (covering 64% of capex).

Listed Places of Worship VAT scheme: claimed in March 2025 after invoicing, reimbursed £3,667 to the parish in April 2025.

Total funding stack:

Source	Amount	% of capex
Buildings for Mission grant	£14,000	64%
Listed Places of Worship VAT scheme	£3,667	17%
Parish reserves	£2,500	11%
Local foundation grant (Cheshire-area Christian heritage trust)	£1,800	8%
Total funding	£21,967	100%
Total capex	£22,000	—

Net cost to parish: £33 (effectively zero).

The install

Install scheduled for January 2025 to avoid disruption to school assemblies and weekend hires. Total install time: 9 working days. Crew of three engineers plus a heritage specialist for the chancel works.

System specification:

• 33 panels total (10 on chancel south slope, 23 on hall main roof)
• 5 kW + 10 kW string inverters (Fronius) with online monitoring
• Black-on-black monocrystalline panels (Project Solar 405W)
• Non-penetrative clamp fixings on chancel; standard commercial fixings on hall
• All cabling in roof void; no visible cables on elevations
• Inverters in modern church boiler room (no impact on listed fabric)
• 5kWh battery added on hall for evening community-use absorption

DNO connection: single-phase G98 approved in week 3. Final commissioning 24 January 2025.

First-year results

The system was commissioned on 24 January 2025. First-year monitoring data (through January 2026):

• Annual generation: 16,520 kWh (versus modelled 16,500 — within 0.1%)
• Self-consumption: 67% (versus modelled 65%)
• Cost avoidance: £3,150
• SEG export income: £640 (5,450 kWh exported at average 11.7p/kWh tariff)
• Total first-year benefit: £3,790

Simple payback on net cost: 0.01 years (net cost was effectively zero). Simple payback on gross capex: 5.8 years. 25-year lifetime savings (modelled): £95,500.

The parish response

The first Sunday after commissioning, the vicar dedicated the sermon to creation care and announced the install in parish notices. The parish magazine ran a four-page feature in March 2025 covering the technical install, the faculty pathway, the Buildings for Mission grant story, and the projected lifetime impact. The local primary school visited the church in June 2025 for a STEM session on solar with the church’s environment champion presenting the monitoring data.

Eco Church survey completed April 2025 — parish moved from Bronze (achieved 2023) to Silver, with the Buildings category jumping from 47% to 81% credit. The parish is now targeting Gold by 2027 with planned heat pump retrofit on the hall and tree-planting in the churchyard.

The parish was featured in the Diocese of Chester’s 2025 Net Zero annual report as one of three exemplar parish solar projects of the year, and the vicar has spoken at two subsequent diocesan deanery synods on the project pathway.

What we learned

A few things from this project that we now apply to every Cheshire-area parish enquiry:

• The combined church-plus-hall model is the right default for most rural Cheshire parishes. Self-consumption economics work much better than church-only.
• The Diocese of Chester DAC is well-organised and supportive of properly-prepared solar applications. Eleven-week faculty grant is achievable for non-controversial parish applications.
• Buildings for Mission grants in the diocese have a strong success rate when the application is properly drafted and the diocesan endorsement is secured.
• Local Christian heritage trusts (Cheshire has several) are an underused funding source. Most parishes don’t apply because they don’t know the trusts exist.
• The school engagement was unexpectedly powerful — the church’s relationship with the local primary school deepened materially as a result of the visible installation.
