Commercial solar is fundamentally a local trade. The roof survey, structural calculation, DNO liaison, council planning conversation and post-commissioning site visits all benefit from an installer who can be on site quickly. This page lists independently operated installer and contractor businesses across the UK, grouped by region, as a starting point for your own research. Solar Panels For Businesses is published by SEO Dons Ltd. We are not an installer, we do not supply or fit solar, and we have not vetted the firms below.
How to check any installer
Before you appoint anyone, check three things yourself: trading history (Companies House record and a customer base you can contact), current accreditations (MCS for solar PV, NICEIC for electrical work, RECC for consumer-facing work, each checked on the scheme's own register), and a credible delivery model (their own engineers and electricians rather than a chain of subcontractors). Ask for an insurance-backed workmanship warranty and for references from projects of your size.
Why local matters for commercial solar
The DNO process alone makes local delivery a major advantage. UK Power Networks, Northern Powergrid, SSEN, NGED, SP Energy Networks and NIE each have different application timelines and pre-application processes. An installer who has filed many G99 applications with your DNO in the last two years will usually move faster than one who has not.
The same logic applies to council planning. The conservation officer, the planning team and the listed-buildings consultant are people with patterns of decision-making that experienced local installers know. National installers can be excellent at the technical work but slower at the soft sign-offs.
Site visits are the third axis. A 50 kW office rooftop install might need three site visits during the design phase: structural survey, electrical infrastructure review and a final walk-through. With a local installer those are short visits; with a national installer they can be day-long trips with travel costs that show up in the quote.
Regions covered
The firms listed cover ten core UK regions. Where a region has more than one firm, they often specialise differently within it (commercial electrical, combined heat-pump-plus-solar and so on), so compare what each says on its own site.
