Frequently asked questions
How much do commercial solar panels cost in the UK?+
Commercial solar costs roughly £800–£1,300 per kWp installed in 2026, falling to £700–£1,000 per kWp on large warehouse-scale roofs as the fixed costs spread further. A 50 kWp system runs about £64,000–£70,000. Most suitable roofs pay back in 4–7 years. Our cost guide breaks the prices down by system size.
Do you need planning permission for commercial solar panels?+
Usually not. Rooftop solar on commercial buildings has been permitted development at any size in England since December 2023, so most installs need no planning application. The main exceptions are listed buildings, conservation areas, and panels projecting more than 200mm above a pitched roof. Our planning guide covers the detail.
Are solar panels worth it for a business?+
For most businesses with a suitable roof and daytime electricity use, yes. With grid power at 25–30p per kWh and rooftop solar generating at an effective 5–8p, typical payback is 4–7 years, followed by a 10–20% return over a 25-year-plus life. Daytime-heavy operations such as warehouses and factories do best.
Is the assessment really free?+
Yes — completely free, with no obligation. We're independent and don't install solar, so there is nothing for us to sell you. If we introduce you to an installer, the installer pays us when that becomes a site survey you asked for, not you. That is how the service stays free for businesses.
What happens after I submit my details?+
You see your indicative system size, savings and payback on screen straight away. If the numbers stack up and you want to go further, we'll tell you whether we can introduce you to an installer who covers your area for a free, no-obligation site survey. The installer confirms the roof and grid connection on site, then give you a costed proposal. You decide.
Do you cover my area?+
The assessment works for any UK commercial roof from your postcode, including England, Scotland and Wales. We are still signing up installers, so we can't promise a site survey everywhere yet: we'll tell you whether we can introduce you to one who covers your area.
