Commercial solar in North West
Sunseam ranks every suitable commercial roof in North West by solar opportunity, so installers find qualified sites and owners see what their roof is worth.
Together these roofs represent an estimated £732,017,386 in potential annual electricity savings from on-site solar. The biggest electricity bills sit under the biggest roofs, exactly the sites Sunseam surfaces first.
Why now in North West
The economics lead: rising electricity and grid charges against a typical rooftop-solar payback of about 4–9 years mean the value is there to capture now. On top of that, the 5,464 buildings at EPC Band D–G in North Westhave a future-proofing reason too, the minimum to let is Band E today, and the government's long-term MEES target is EPC B for large non-domestic buildings (over 1,000 m²), expected ~2031. Solar cuts bills and lifts a building's rating. See the MEES & commercial EPC guide.

The minimum to let commercial property is Band E today; the government's long-term MEES target is EPC B for large non-domestic buildings (over 1,000 m²), expected around 2031, so the biggest, lowest-rated roofs have the clearest future-proofing reason to act, on top of the bill savings.
Figures are estimates modelled using standard assumptions, indicative, not quotes.
Our capacity estimates are under revision. Where several adjoining units share one mapped roof outline, or where no outline could be matched and we size from floor area instead, an individual estimate can be too high or too low. We are rebuilding how roof size is measured and will restate the affected figures once that work is complete. Roof counts, energy ratings and ownership figures are unaffected.
