About this site: independent guides to paying for commercial solar
Reviewed by the Commercial Solar Finance editorial team (we take no installer or lender commissions). Last reviewed: 14 October 2026.
Commercial Solar Finance publishes guides, calculators and a route checker that compare the ways a UK business, charity or public body can pay for a commercial solar array. It is an editorial site. It does not install solar, lend money, broker finance or operate an installer panel.
Explains the routes (cash, hire purchase, loan, lease, PPA), the tax relief that goes with each, and the funding that is still open, with the source for every figure.
It does not install, lend, arrange finance, take commission, or pass enquiries to installers or lenders.
What this site is
Most commercial solar conversations start with the system: an installer surveys the roof, proposes a size and quotes a price, and the finance question is attached afterwards. This site starts the other way round, with the tax position, the premises and the budget, because those decide which route is cheapest. The finance route checker ranks the five routes from six answers; the six routes compared page sets out the trade-offs; and the capital allowances guide covers the tax relief.
How the guides are written
- Every figure has a source. The money pages end with a claims table naming where each number comes from and the date it was checked. If a number is not in the table, it should not be on the page.
- Modelled examples are labelled. Case studies and worked examples are illustrative, built from published scheme rules and typical prices. They are not client engagements.
- Dates are shown. Pages carry a last-reviewed date. Schemes close and rates change; where a scheme has closed, such as the Public Sector Decarbonisation Scheme in November 2024, the page says so.
- Corrections are welcome. If a figure is wrong, email us and we will check it against the source.
Independence
We take no commission from manufacturers, installers, lenders or developers, and we do not accept payment to rank or recommend a provider. We are not a lender, an installer, a broker or an advisor. Where a page names lenders or providers, it does so to explain who writes which route, not to recommend one. See pricing for what is free.
What happens to an enquiry
Enquiries sent through the forms on this site are read and answered by email. No installer or lender receives them, and we do not pass your details to installers or lenders without your permission. If that ever changes, this page will say who receives enquiries and on what terms. The privacy notice sets out how your details are handled.
Scope
UK only: UK tax allowances, regional funding schemes, accounting standards and DNO rules. Commercial and public-sector projects, typically systems above 50–80 kWp. Household solar and consumer loans are outside scope. If you cannot tell which route fits, start with the finance route checker.
