Grants and funding for solar canopy installers

How solar canopies and carports are actually funded in 2026

A solar canopy costs more per kilowatt than a rooftop array because you are also buying a steel structure and its foundations — roughly 45% of the total. That extra capital is exactly why the funding question decides most canopy projects: get the route right and a scheme that looks like a 9–12 year payback on paper becomes cash-positive from year one. There is no single "solar canopy grant"; instead a handful of tax reliefs, export payments, EV-charging grants and finance structures stack together, and which ones apply depends on whether you are a business, a school, an NHS trust or a homeowner. Below is the honest, current picture — including the schemes that have closed, so you don't waste time chasing funding that no longer exists.

For businesses: capital allowances do the heavy lifting

The biggest lever for a commercial canopy is tax, not a grant. Solar PV is classed by HMRC as a special-rate ("integral features") asset, which means one important thing: it is excluded from 100% full expensing. Anyone telling you a solar carport qualifies for full expensing is mistaken. What it does qualify for is the Annual Investment Allowance — 100% relief on up to £1m of qualifying investment a year, available to companies, sole traders and partnerships — which is the practical route to writing off the PV plant against profit for almost every single-site canopy. Companies can also use the 50% first-year allowance on expenditure above the AIA cap, with the balance going into the special-rate pool. On top of that, on-site solar and battery plant is exempt from business rates in England until 31 March 2035, so a canopy will not push up your rateable value. Always confirm the split between the PV (special rate) and the structural steel with your accountant, because they can be treated differently.

Export income: the Smart Export Guarantee

The Feed-in Tariff closed to new applicants back in 2019, so today the mechanism that pays you for surplus generation is the Smart Export Guarantee (SEG). Licensed suppliers with 150,000+ domestic customers must offer a rate above zero on systems up to 5MW; in practice rates run from around 1p to 15p per kWh depending on supplier and tariff. To claim it you need an MCS-certified installation, an export MPAN and a smart meter recording half-hourly export. The important point for a canopy is that self-consumed solar is worth roughly twice exported solar — you avoid buying grid power at 30–47p rather than selling it at a few pence — so we always size and orient a canopy to maximise on-site use first, and treat SEG as the safety net for the surplus.

EV charging: the Workplace Charging Scheme

If you are putting chargers under the canopy — and most commercial clients are — the Workplace Charging Scheme is open until 31 March 2027. From 1 April 2026 it covers up to 75% of the cost of a socket, capped at £500 per socket (£2,000 for state-funded education), for up to 40 sockets, claimed through an OZEV-authorised installer. It only funds the charge points, not the canopy or the PV, but it meaningfully offsets the EV layer that makes canopy economics work. Note that the separate EV infrastructure grant for staff and fleets closed to new applicants on 31 March 2026 — it is no longer available, so ignore any guidance that still lists it.

Schools, the NHS and the public sector

Public-sector funding shifted in 2024–25 and it is easy to be caught out by out-of-date advice. The Public Sector Decarbonisation Scheme (PSDS/Salix) is closed to new applicants (Phase 4 closed in November 2024; only already-awarded projects run to 2028). The live route is now Great British Energy, which committed up to £30m to 34 NHS trusts in October 2025 for solar including car-park canopies, within a wider public-sector programme worth up to £255m across the NHS and schools. Schools can also use Salix interest-free loans repaid from the energy savings, which — combined with GB Energy capital — can make a school canopy close to net-cashflow-neutral. A real reference point: Princess Royal Hospital in Telford is installing a 200kW solar car-park canopy with £445,000 of GB Energy funding, saving about £35,000 a year. We prepare the applications and evidence for these routes as part of the project.

Homeowners: 0% VAT and the export tariff

Domestic solar installations in Great Britain are zero-rated for VAT until 31 March 2027 (reverting to 5% after), which is worth several thousand pounds on a residential carport. One honest caveat: HMRC's guidance zero-rates solar installed "in, or in the curtilage of" a dwelling, but it does not explicitly confirm a standalone carport in the garden, so we advise homeowners to check their specific case. Beyond VAT, domestic carports earn SEG on their surplus, and there is no residential grant scheme comparable to the public-sector routes — the case for a home carport rests on independence from the grid, EV charging and property value rather than subsidy.

No upfront cost: the zero-capital PPA

Where the capital simply isn't available, a Power Purchase Agreement removes the barrier entirely. A funder designs, pays for, installs and maintains the canopy; you host it and buy the electricity it generates at a fixed rate below grid price over a 10–25 year term. It keeps the asset off your balance sheet and is the private-sector equivalent of a public grant — increasingly the default for retail chains and multi-site operators.

A note on the "solar car park mandate"

You may have read that solar canopies are about to become mandatory on large car parks. The Government ran a call for evidence on exactly that between May and June 2025, but as of late 2025 the core solar-canopy mandate had not been taken forward — only the EV-charging elements progressed. So it is not law, and you should treat it as a reason to future-proof ahead of a likely direction of travel, not as an existing requirement. The individual routes below are the ones that are real and claimable today.
