The position in libraries, museums & galleries

This category sits within the non-domestic MEES regime in England and Wales. The E minimum applies now, and buildings over 1,000 m² are expected to need EPC B by 2031.

The pattern across most categories is the same: lighting, controls and air-tightness deliver the first points cheaply, and the expensive measures are fabric and plant.

This category accounts for 0.2% of all commercial certificates on the register. 138 properties are rated F or G – below the minimum that has applied to lettings since April 2023 – and 74 have an expired certificate that was rated F or G when issued.

The largest concentrations are in Westminster, Cornwall, North Yorkshire, Camden, Southwark, Dorset.
