Which buildings in Lancaster face MEES pressure?

Around 111 of the ranked buildings in Lancaster 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.
