An independent UK commercial solar funding guide — not a solar installer.
We started this firm because too many UK businesses were being walked into the wrong grant by installers who only had one product to sell.
Why "independent" matters in commercial solar funding
Most UK installers offer some form of "we'll help with grants" service. The structural problem is that they only get paid if you build — so the incentive is to find any grant that will get you over the line, even if a different funding stack would be better. We have no installation revenue. We charge a fixed fee for the funding work, plus an optional project management fee on the build. That keeps us honest: if the right answer is "don't build this", we say so, because our P&L doesn't depend on the project happening.
Always check any installer you use is MCS-certified. We project-manage the build, hold one set of contracts on your behalf, and stay on the line until handover sign-off.
Is it free?
This site is free to use. If you send an enquiry through one of our forms, we reply by email.
What we don't do
We don't sell solar panels. We don't sign you up to retainers.
How to start
The fastest route is the free funding review form. It takes four minutes and gives us enough to come back by email with a grant shortlist and ballpark numbers.

Tell us your sector, roof size and energy spend. We reply by email with a shortlist of grants and the realistic capex you can expect to recover.
No obligation. We don't charge for grant scoping.
Funding by asset class
The allowance depends on the asset, and most pages on this topic get it the wrong way round. Solar PV is special-rate expenditure (HMRC Capital Allowances Manual CA22335), so the 100% year-one route is the Annual Investment Allowance — Full Expensing is a main-rate measure and does not reach it. Battery storage, EV charging and heat pumps are Heat pumps for space or water heating are special-rate: AIA, then the 50% FYA. Standalone batteries are probably main-rate (full expensing for companies), but HMRC has no specific guidance; confirm with your adviser.
- commercial heat pump prices by system size
Special-rate integral feature: AIA up to £1m, then the 50% special-rate first-year allowance for companies; full expensing does not apply.
- battery storage economics for commercial sites
Probably main-rate plant (HMRC has no specific guidance, so confirm with your adviser). Stacks with solar for self-consumption.
- commercial solar capex bands for 2026
Capex bands per kWp before any relief.
- solar panels for industrial buildings
Large roofs, high daytime load — the strongest case.
- AIA on a commercial solar installation
Solar is special-rate, so AIA is the 100% year-one route.
Find out which 2026 schemes your site actually qualifies for
- 1. A short written funding note naming every scheme your site qualifies for in 2026 — and the ones it does not.
- 2. Indicative system size and a capex band for your roof.
- 3. Year-one tax treatment per asset in £ — solar is special-rate expenditure, so the route is the Annual Investment Allowance; heat pumps for building heating are also special-rate integral features, and standalone battery storage is probably main-rate plant (HMRC has no specific guidance, so confirm with your adviser). Most pages get this the wrong way round.
- 4. Projected SEG export revenue at current rates.
- 5. Any red-flag eligibility or DNO issues we can see up front.
Covers solar PV, battery storage, EV charging and commercial heat pumps — separately or as one bundled project. If your project is a heat pump or a battery rather than a roof, say so in the message box and the note is written against that asset instead.
