Bedroom and loft air conditioning in Westminster
In London, heat soaks into brick and concrete during the day and comes back out at night, which is when it is hardest to sleep. For bedrooms in Westminster, we place the outdoor unit at the back of the house, away from neighbours' windows.
Top-floor flats in Westminster feel the heat most, because the roof sits right above the bedroom. Westminster is part of our London coverage. That includes the SW1A, SW1E, SW1H, SW1P, SW1V and SW1W postcode districts.

Guide prices show VAT at 20%. HMRC treats most fixed air conditioners and air-to-air heat pumps installed in homes as energy-saving materials, zero-rated until 31 March 2027 when we supply and fit them. If your installation qualifies, your quote shows 0% VAT and a lower price. Servicing, repairs, cleaning and controls are charged at 20%.
Planning and permissions
For most houses in Westminster, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.
The survey
The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote. Surveys in Westminster cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
