Frequently asked questions
How many commercial roofs suit solar in Cardiff?
Sunseam ranks 1,021 large commercial roofs in Cardiff, with a combined rooftop-solar potential of about 277.9 MWp.
Which buildings in Cardiff face MEES pressure?
Around 298 of the ranked buildings in Cardiff 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.
