A smarter way to power your business
Electricity you generate on your own roof costs a fraction of what you buy from the grid. With UK business electricity averaging around 24p per kWh, every unit you generate and use yourself is a unit you never have to buy. Our guide on whether commercial solar panels are worth it for UK businesses works through the case in detail.
Cut your electricity bills
Self-generated power covers the bulk of daytime demand, and every self-consumed unit avoids the full grid rate you would otherwise pay.
Hedge against price rises
Every kilowatt you produce is one you do not have to buy, so solar steadies your cost base while wholesale markets keep moving.
Generous tax relief
The Annual Investment Allowance lets you deduct 100% of the cost against pre-tax profits, worth roughly 25p in the pound at the main corporation tax rate.
No business rates increase
Eligible rooftop solar is exempt from business rates through to 2035, so adding generation does not raise your rateable value.
Earn from exported power
Surplus generation is paid for under the Smart Export Guarantee. Export rates sit below what you pay to buy a unit, which is why self-consumption matters most.
Evidence for ESG reporting
On-site generation is measurable, auditable carbon reduction that strengthens tenders, reporting and your green credentials.

Indicative cost bands by system size
Commercial solar is quoted per kilowatt-peak (kWp), and the rate per kWp falls as the system grows. Roof type, access and whether you add battery storage move the figure most. These are the bands we see across UK installs. Our guide to what commercial solar panels cost in the UK explains what sits behind them.
| System size | Typical UK cost band | Indicative payback | Suited to |
|---|---|---|---|
| 10 to 20kWp | Low tens of thousands | 5 to 8 years | Small office, shop or unit |
| 20 to 50kWp | Mid tens of thousands | 4 to 8 years | Larger retail or small industrial |
| 50 to 150kWp | High tens of thousands | 4 to 7 years | Mid-sized industrial site |
| 150kWp+ | Six figures upwards | 4 to 7 years | Large warehouse or estate |
The numbers work harder than you think
Government incentives cut the net cost of a system sharply and can take a year or more off payback. Here is what a UK business can claim.
100% Annual Investment Allowance
Deduct the full qualifying cost from pre-tax profits in year one, up to £1m. At the 25% main rate that is worth roughly 25p in every pound you spend.
50% first-year allowance
Solar is special rate plant, so spend above the AIA cap can attract a 50% first-year allowance for limited companies, with the balance written down at 6% a year.
Business rates exemption
Eligible rooftop solar is exempt from business rates through to 2035, so the investment will not push up your property rateable value.
Smart Export Guarantee income
You are paid for the surplus you send to the grid. Suppliers set their own SEG rates rather than government, so they are worth comparing. How the Smart Export Guarantee works.
Store the sunshine, use it after dark
On its own, solar covers your daytime demand and exports the rest. A battery captures that surplus so you can use it in the evening, on dull days and at peak-price times. Because an exported unit earns less than a bought unit costs, lifting self-consumption from around half to 70-80% is where the extra return comes from.
