The major grants closed. The maths still works.
IETF and PSDS closed to new applications in 2024. Full Expensing, SEG, REPF, 0% VAT and PPAs are still active — and stacked properly, still pay back commercial solar in 4–6 years. We're the independent funding consultants who know what's actually open.

2026 Grant & Incentive Status
The definitive UK commercial solar funding picture — confirmed against gov.uk, Salix Finance and DESNZ announcements.
UK commercial solar funding looks very different in 2026 than it did 12 months ago.
Three of the four major commercial solar grant schemes — IETF Phase 3, PSDS Phase 4 and UKSPF — closed to new applications during 2024–2026. Most online guides still describe them as live. Our job is to give you the honest 2026 picture: which schemes are actually open, which closed, and how to assemble a funding stack that pays back without depending on grants that no longer exist. The combination of Full Expensing, SEG, 0% VAT, PPAs and (for rural businesses) REPF still delivers 4–6 year payback on most commercial solar projects.
What's actually still open in 2026
The active UK commercial solar funding stack in May 2026 has five legs. First, tax allowances — Annual Investment Allowance and Full Expensing — which are guaranteed for any UK incorporated company paying corporation tax and effectively reduce net solar capex by 25%. Second, 0% VAT on solar, recently extended from domestic to commercial, which is a 20% reduction in VAT-inclusive cost with no application required. Third, private finance via Power Purchase Agreements — third-party investors own the asset, you buy electricity at a fixed pence/kWh below grid prices, zero capex from you. Fourth, export revenue through the Smart Export Guarantee, with dynamic tariffs paying 25–40p/kWh during system peaks. Fifth, residual targeted grants — REPF for rural businesses, the new Local Growth Fund in 11 Mayoral Authority areas, Salix interest-free loans for public sector, GBE Community Fund for community-led projects, and the still-active Scottish IETF for Scottish manufacturers.
Most businesses we speak to assume they need a grant. In 2026 — with IETF and PSDS closed — the honest answer is that for the majority of SMEs the combination of Full Expensing + 0% VAT + a competitive PPA beats any active grant on net cash, with none of the application risk. See current commercial solar costs by system size.
Why an independent funding partner matters
We are not a solar installer. We don't sell panels. Our revenue comes from delivering successful applications and from project management on grant-funded builds — which means we have no incentive to push you into a £400,000 system when £180,000 would pay back faster. With the major grants now closed, our value is even sharper: keeping you out of fantasy projections about schemes that don't accept new applications, and steering you to the active routes that genuinely move payback. More about how we work.
Different schemes apply to different sectors. Pick yours for the funding stack that actually fits.
Each sector page has the live grant deadlines, eligibility rules, typical project sizing and one or two case studies. If your business doesn't fit cleanly into one of these, ring us — half our work is for businesses that no installer's "sector page" covers.
Manufacturing & Industrial
English IETF closed; the working stack is Full Expensing + PPA + SEG. Scottish manufacturers still have SIETF.
See sector fundingAgriculture & Farms
On-farm PV with REPF (council-administered), Annual Investment Allowance and SEG export. Typical payback under 7 years.
See sector fundingSchools, Academies & FE
PSDS Phase 4 closed November 2024. Salix BAU loans and LCSF (HDP funding) remain. Stay ready for any Phase 5.
See sector fundingNHS & Healthcare
PSDS new applications closed; existing awards delivering through 2028. Salix interest-free loans still available.
See sector fundingHotels & Hospitality
Hotel groups using PPAs and Full Expensing reduce fixed-cost electricity by 40–60% with zero upfront capex.
See sector fundingWarehouses & Logistics
Large rooftops + half-hourly demand make logistics one of the strongest commercial PV ROIs in the UK today.

Nine active routes — layered to replace what closed.
A typical commercial solar project doesn't use just one route. The right answer is normally a stack — for example, Full Expensing (25% effective tax saving) + 0% VAT (20% off VAT-inclusive cost) + a PPA (zero capex on operating expenses) + SEG (export revenue) — that lands a 4–6 year payback. See the full guide to commercial solar grants and incentives — every active vs closed scheme for 2026.

Energy audit + design
We pull half-hourly meter data, build an MCS-compliant PV design, and a fully costed financial model — capex, payback, IRR, NPV.
Application drafting
We write the funder-specific narrative — IETF needs decarbonisation pathways, PSDS needs Heat Decarbonisation Plans, REPF needs rural growth metrics.
Decision + delivery
On grant approval, we project-manage the build through one of our MCS-certified installer partners. You sign one set of contracts.
Commercial solar funding is regional. We track every UK programme.
National grants like IETF and PSDS apply UK-wide, but devolved nations have their own programmes — Scotland's Energy Transition Fund, Welsh Government's industrial decarbonisation budget, Invest NI capital grants. Then there are LEP and freeport allocations, mayoral combined authority funds, and council-led schemes. We track all of them.

"Daniel and the team rebuilt our solar project as an integrated decarbonisation package and walked us through the IETF scoring before we wrote a line. The £142k grant award was the difference between an internal hurdle miss and a board-approved capex. Honest, technical, and zero fluff."
"Priya understood public sector procurement better than our framework consultants. We secured 100% PSDS funding across six schools with no trust capex contribution — exactly what the bursary team needed to see. They came in early enough to do the HDP properly, and that bought the award."
"The REPF productivity narrative they wrote was a different category from anything I'd seen from other consultants. They turned a generic decarbonisation pitch into a jobs-and-contract-drying story that the council's economic development team scored top of pile. £62k of grant on a project I assumed wasn't fundable."
