Air conditioning in PH43: what works for a typical home

In PH43 last summer (2026) there were ≈0 nights that stayed above 18 °C — the 1991–2020 average is 0.0 (ERA5 reanalysis, grid ≈30 km, lower than street temperatures in cities). An air-conditioning unit used for cooling is outside Class 6H, which covers heating and hot water only, so a planning application may be needed; a heat pump used only for heating can be permitted if it meets the noise and siting rules (checked 25 Sep 2026).
