Do I need planning permission for air conditioning in Rotherham?
For most houses in Rotherham a reversible air-to-air unit is permitted development if it's under 1.5 m³, meets 37 dB at the neighbour's window and isn't on a wall facing the road in a conservation area; flats are limited to one unit per building up to 0.6 m³ (Class G as amended 29 May 2025, checked 25 Sep 2026). Rotherham has 28 conservation-area records on file (status on-record, snapshot 25 Sep 2026).
