Why installer choice matters more for churches than other buildings
For a warehouse or office solar install, choosing the cheapest MCS-certified installer is usually fine. The consent route is standard planning permission. The grant landscape is straightforward. The technical challenge is modest. Price is the dominant variable.
Church solar is different in almost every dimension:
- The consent route is specialist. For CofE churches, faculty jurisdiction applies — a legal process entirely separate from the planning system. The installer's knowledge of the Care of Churches Measure 2018, the DAC process, Statement of Significance conventions, and the Consistory Court hierarchy directly determines how long and how expensive your project takes.
- The building fabric is irreplaceable. A Victorian slate roof, a medieval stone parapet, a Georgian chancel — these cannot be repaired cheaply if damaged. The fixings, the access logistics, the installation method all require heritage-appropriate engineering that generalist installers haven't developed.
- Grant funding is complex, denomination-specific and it moves. Buildings for Mission, the Demonstrator Churches Project, diocesan capital programmes, the National Lottery Heritage Fund, Methodist Net Zero and Catholic diocesan funds all have their own criteria — and the Listed Places of Worship VAT scheme closed on 31 March 2026. An installer working from a two-year-old funding list will point your PCC at a scheme that no longer exists.
- The client relationship is long. Faculty applications take months; grant applications run concurrently; completion reporting follows installation; the parish will want ongoing monitoring support. The installer you choose will be in your life for 12–24 months, not just for installation week.
These differences mean that the evaluation criteria for church solar are almost entirely different from standard commercial solar procurement. Below is the framework we recommend PCCs, treasurers, and churchwardens use.

The real cost of choosing the wrong installer
The scenario we see most often: a PCC takes a quote from a generalist commercial solar firm — often at a headline price 10–15% below our quote. The installer has done school and warehouse work. The PCC is persuaded by the lower number. The contract is signed.
What follows is predictable:
- Faculty application submitted without proper heritage input. The Statement of Significance is thin — it describes the building's architecture but doesn't engage with the impact of the proposed installation. The Statement of Needs doesn't cite the diocesan Net Zero strategy. The application drawings are CAD exports rather than heritage-quality visuals.
- DAC sends it back. Typical first-round DAC response: request for revised Statements, heritage impact visualisations from agreed viewpoints, and structural engineer's sign-off on the reversibility of proposed fixings. Timeline lost: 6–12 weeks per round.
- Second round submitted, possibly with heritage consultant added. This costs the PCC £1,500–£3,500 for the consultant they now need on top of the installer fee. Another 8 weeks.
- Faculty granted — but with conditions. The chancellor specifies that panels must not be visible from the north elevation, which wasn't modelled in the original design. The installer now needs to redesign the layout. Additional engineering cost.
- Variations start arriving. The original quote didn't include reversible fixings for the listed chancel roof — those are extra. The crane access logistics weren't properly modelled — extra. The electrical supply from the vestry isn't big enough — upgrade cost not included.
- Total outcome: Project 10–16 months behind original timeline. Total cost 20–35% above original quote. PCC goodwill significantly damaged. Relationship with diocesan architect strained.
The 10–15% saving on installation cost has been eliminated many times over. The specialist premium — typically £1,000–£3,000 — now looks like the best investment the PCC could have made.
This is not a hypothetical. It is a composite of cases we have been asked to take over mid-project after generalist installers ran into difficulty. We see several of these every year.
Already mid-project with the wrong installer?
We take over stalled church solar projects. If your DAC has sent back the faculty application, if variations are arriving on a quote you thought was fixed-price, or if your installer has gone quiet — call us. We assess whether rescue is viable and will tell you honestly if it isn't.

When a solar installer is presenting to your PCC, these are the warning signs that suggest they lack the heritage church experience to deliver reliably:
- "We've done churches before" without being able to name three specific CofE projects with faculty granted — ask for names, contact details, and the chancellor's approval date.
- No mention of faculty in their initial presentation — generalist installers often don't know it's required for CofE consecrated buildings.
- Standard blue-cell panels specified — heritage DACs require black-on-black (black frame, black backsheet) for listed buildings in almost all cases. Standard blue-cell panels will almost certainly be rejected.
- No mention of Buildings for Mission or the Demonstrator Churches Project — an installer who does not know the current programmes cannot help you reach them. Equally, an installer still promising an LPW VAT claim is quoting a scheme that closed on 31 March 2026.
- No structural engineer mentioned — every heritage church solar application requires a structural engineer's report confirming the roof can bear the panels. If the installer hasn't mentioned this, they haven't planned the project properly.
- Very low headline price with "TBC" items — a fixed-price proposal should include all professional fees, engineering, permitting, installation, and commissioning. "Additional costs TBC" in a heritage church context is a red flag.
- Unusually short lead times — a realistic faculty-to-commissioning timeline for a listed CofE church is 16–28 weeks. An installer quoting 8 weeks either doesn't understand the process or is being dishonest.
How to verify installer credentials
Before shortlisting any installer for church solar work:
- MCS commercial certification — check via the MCS installer search (mcscertified.com). Domestic-only MCS certification is not sufficient for commercial-scale church systems (typically above 4 kW).
- Faculty references — ask for three named CofE parish references where faculty was granted, including the diocese, the approximate grant date, and the parish churchwarden's contact. Call at least one. Ask specifically: was it granted first time or were there revisions? Were there any cost variations from the original proposal?
- EASA membership or EASA-aligned design — the Ecclesiastical Architects and Surveyors Association represents the professionals who advise DACs. An installer working in EASA-aligned practice understands what DACs expect.
- Grant writing track record — ask for examples of successful Buildings for Mission applications. BfM application narratives can be anonymised and shared; a specialist who has written forty of them will have examples. An installer who has never written one cannot credibly claim grant application capability.
- Diocese spread — an installer who has worked in 15+ dioceses has encountered a wide range of DAC practices and chancellor expectations. An installer with one or two diocese references may have been lucky with a cooperative DAC rather than genuinely experienced in the process.
How to compare quotes properly
When comparing two or more quotes for your church solar project, the headline £/kW figure is the least useful comparison point. Build a like-for-like scope before comparing prices:
- Faculty writing included? If not, add £2,000–£5,000 for a heritage consultant.
- Grant application writing included? If not, add £1,500–£3,500 for a grants writer.
- DAC engagement (pre-application and formal) included? If not, plan for additional professional time cost.
- Structural engineer's report included? If not, add £500–£1,500.
- Heritage panel specification (black-on-black)? Some cheaper quotes specify standard panels. Switching to heritage panels later adds cost and delay.
- Reversible fixings for listed-fabric elements? Standard clamp fixings are not appropriate for listed stone, slate, or tile roofs.
- Is the installer charging the right VAT rate? Energy-saving materials in a building used solely for a relevant charitable purpose are zero-rated until 31 March 2027. A quote showing 20% VAT on a church install is a question worth asking before you sign.
- Workmanship warranty period and backing? 10 years insurance-backed is the industry standard for heritage church work.
In our experience, when a like-for-like scope is assembled, the apparent price difference between a specialist and a generalist narrows significantly — and in many cases the specialist quote is lower on a full-scope basis.
What we won't do
Three commitments that should be standard for any reputable specialist installer:
- We won't recommend solar where it doesn't make sense. Approximately 15% of parishes that enquire with us receive a recommendation to wait, to scope down to hall-only, or to prioritise other energy improvements first. We'd rather lose work than oversell a project that underperforms.
- We won't issue cost variations without your written approval. Our fixed-price proposal includes all professional fees, engineering, permitting, installation, and commissioning. The number we quote is the number you pay unless you request changes to scope.
- We don't take a percentage of grant awards. Grant application writing is included in our standard project fee. We have no incentive to inflate grant applications — the grant you receive belongs to your parish.
Frequently asked questions about choosing an installer
Do I need a specialist installer for a CofE parish church?
Not legally — any MCS-certified commercial installer can quote for church solar. But faculty applications require specific knowledge of the Care of Churches Measure 2018, DAC requirements, and Statement of Significance conventions. Installers without this experience routinely produce applications that DACs send back, adding months and cost. If your building is listed Grade II, II* or I, or if you need Buildings for Mission grant writing, a specialist is strongly advisable.
How much more does a specialist installer charge?
Typically 5–15% more on the installation element, which is usually £1,000–£3,000 on a standard parish project. But specialist installers include faculty writing, grant application drafting, and DAC engagement in their fee — services that would cost £2,000–£8,000 separately from a heritage consultant. On a like-for-like scope basis, specialists are frequently cheaper.
What happens if a faculty application is rejected?
A DAC objection is not a rejection — it triggers a revision cycle. Most objections are resolved at the DAC stage; formal refusals require appeal to the Consistory Court. A poorly written faculty from an inexperienced installer typically requires 1–3 revision rounds, adding 3–8 months to the timeline. Each revision round adds project management and professional time cost.
How do I verify an installer's faculty experience?
Ask for the names of at least three CofE parishes where they have delivered faculty-approved solar installations, with the chancellor's name and approximate grant date. Call those parishes directly. Ask specifically: was the faculty granted first time, or did it require revisions? Were there any variations from the fixed-price proposal?
Can a generalist installer write a Buildings for Mission application?
Yes, but the quality is typically poor. BfM applications require: a credible stewardship narrative, accurate self-consumption modelling, diocesan Net Zero plan citation, and a relationship with the Diocesan Net Zero Officer. Installers without church experience consistently produce thin mission sections and over-optimistic financial modelling — both of which assessors notice and discount.
What happened to the Listed Places of Worship VAT Grant Scheme?
It closed. DCMS stopped accepting applications from new and returning applicants on 31 March 2026, the £23 million 2025-26 budget was fully allocated, outstanding decisions were issued by 15 April 2026 and the government confirmed there would be no further funding rounds. In England it is replaced by the Places of Worship Renewal Fund — £92 million over four years, delivered by Historic England — but that is aimed at repair and maintenance of buildings most at need and its published criteria do not mention solar, so do not assume a PV project qualifies. For solar specifically the closure matters less than it sounds: the installation is zero-rated for VAT until 31 March 2027 in a building used solely for a relevant charitable purpose, so there is no 20% to reclaim in the first place. Treat any installer still offering to handle your LPW claim as a warning sign about how current their funding knowledge is.
