Deduct 100% of qualifying spend, up to £1 million a year, from your taxable profits in the year you buy the system. For a company paying the 25% main rate of corporation tax, that’s up to 25p back for every £1 invested. Companies, sole traders and partnerships can all claim it.

For solar spend above the £1 million AIA limit, companies can claim 50% of the cost in year one. The rest is written down at 6% a year. Solar panels are “special rate” assets, so they don’t qualify for 100% full expensing. This allowance was due to end in March 2026, but it has since been made permanent.

Eligible onsite solar panels and battery storage in England are exempt from business rates from 1 April 2022 until 31 March 2035. Adding solar won’t raise your property’s rateable value during that period, so none of your savings go to a higher rates bill. Scotland, Wales and Northern Ireland set their own rules.

Get paid for the surplus electricity your system exports to the grid. The SEG covers eligible installations up to 5MW in Great Britain. Rates vary by supplier, and you don’t have to use your electricity supplier, so it pays to compare tariffs. Battery storage can help you decide when to use your power and when to export it.

Commercial solar installations are charged at the standard 20% rate of VAT. VAT-registered businesses can normally reclaim it through their VAT return, and capital allowances are then claimed on the cost excluding VAT. Organisations that aren’t VAT-registered can’t reclaim it, so we build it into their budget from the start.

There’s no single national solar grant for businesses, but some councils and regional programmes part-fund energy-saving projects. Availability changes often, and many grants pay out only after installation. Some also limit how the rest of the project can be funded. We’ll check which schemes are open in your area and whether they combine with your chosen route.

Send us your site address and at least 12 months of electricity bills. Half-hourly consumption data is even better, because it shows exactly when your site uses power. We’ll also ask about your roof or land, how long you plan to stay on the site and any upcoming changes to your energy use.

Our engineers design a system sized to your demand and model its annual generation for your location. We then compare CAPEX, PPA, Lease to Own and Green Loan side by side, showing the upfront cost, payback period, 25-year savings and carbon reduction for each, with the relevant tax reliefs included.

Once you’ve chosen your finance option, we handle the next steps. For a PPA, we arrange the funding. For a Green Loan or Lease to Own, we give your lender the technical and financial data they need. We also manage the grid connection application with your local network operator (DNO).

Our in-house accredited teams install and commission your system, then hand over full documentation. From that point, we monitor its performance and carry out maintenance, so it keeps delivering the savings in your business case for the whole finance term and beyond.
