typical commercial rooftop payback
Commercial electricity and grid charges keep climbing, and the biggest bills sit under the biggest roofs. Owners are moving to capture that value now, which is exactly the set of sites the ranking surfaces first.
The minimum rating to let is Band E today. The long-term target is EPC B for large non-domestic buildings, expected around 2031, and that captures most warehouses and sheds. Solar lifts a building's band, so owners de-risk ahead of it.
Sunseam estimates.
Every qualifying commercial roof in it, scored and ranked against each other.
Installable capacity, the estimated annual benefit, and what the building is up against.
Save a roof to your pipeline, with stages, notes and an outreach log per site.
The avoided-bill saving is capped at your own electricity bill. Export income is shown separately rather than folded in to make the total look bigger. Self-consumption is modelled per building, not assumed.
No invented owners and no fake numbers. A local installer confirms the exact figures for your roof before you commit to anything.
Sunseam helps commercial building owners cut their energy bills with rooftop solar. Enter your building's address to see an instant estimate of what solar could save you, then we connect you with a local installer for firm quotes.
It depends on your roof size and how much electricity you use by day. Commercial rooftop solar commonly delivers a total benefit of low tens of thousands to six figures a year. That's split between the avoided electricity bill (capped at your own bill) and export income on the surplus. Payback is usually ~4–9 years, faster the more you use on-site. Use the calculator to get an estimate for your building.
Yes, the savings estimate is free with no sign-up. Getting connected with a local installer for firm quotes is free too, with no obligation.
Often, yes. On-site solar reduces your building's assessed energy use, which can lift its EPC band. The minimum rating to let commercial property is currently EPC E; the government's long-term goal is EPC B for large non-domestic buildings (over 1,000 m²), expected around 2031, so lifting your band future-proofs a big warehouse or shed. (The earlier 2027 'Band C' step for commercial property was dropped in 2026.)
Estimates are modelled from official UK building and energy data using standard industry assumptions, then a local installer confirms the exact figures for your building. The avoided-bill saving is capped at your building's own electricity bill, with export income shown separately on top, and self-consumption is modelled per building.
We review your building and match you with a local installer who covers your area. If it's a fit. They get in touch to confirm the figures and arrange quotes. There's no obligation, and if we're still expanding in your area we'll tell you rather than leave you waiting.
