Why commercial solar

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.

What it costs

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.

Indicative commercial solar cost bands

Why the payback range Payback assumes typical daytime self-consumption. Sites that use most of what they generate sit at the shorter end; sites exporting a large share sit at the longer end. We model your own figures at the free assessment.
Tax and incentives

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.

Solar and battery storage

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.

Use stored solar in the evening instead of buying from the grid
Lift self-consumption to roughly 70-80% of what you generate
Charge cheaply off-peak and discharge at peak rates
Keep essential equipment running through short outages
In four steps

From first call to first kilowatt

Comparing and installing commercial solar is more straightforward than most people expect. How commercial solar works explains the system itself end to end.

We review your bills, roof and usage pattern, then model the right system size and the savings you can realistically expect.

Design and quote

You get a clear proposal with costs, expected output, payback and the tax relief your business can claim.

Installation

Accredited installers fit the panels and any battery with minimal disruption, usually inside a few days.

Generate and save

Your system switches on, your bills drop, and you start earning on any power you export.

Is your site suitable?

What makes a good solar candidate

Most commercial premises are a strong fit, and the assessment confirms the detail. These are the signs solar will pay back quickly for you.

A sizeable roof or yard. Warehouses, factories, offices and retail units usually have room for a worthwhile array.
Daytime energy use. The more power you use while the sun is up, the more of your own generation you consume directly.
High electricity bills. Larger bills mean bigger savings and faster payback on the same system.
A sound, unshaded roof. South or east-west facing roofs in good condition give the best return, though most orientations work.
Plans to stay put. Owning your premises, or holding a long lease, makes the long-term return easy to capture.
An eye on net zero. If carbon reporting or green tenders matter, on-site generation is a clear, measurable win.
