Frequently asked questions
How many commercial roofs suit solar in Westminster?
Sunseam ranks 2,517 large commercial roofs in Westminster, with a combined rooftop-solar potential of about 873.3 MWp.
Which buildings in Westminster face MEES pressure?
Around 731 of the ranked buildings in Westminster sit at EPC Band D–G. The minimum to let 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.
