Bedroom and loft air conditioning in Wimbledon
Loft conversions and top-floor bedrooms in Wimbledon gain heat through the roof all day and give it back at night. The urban heat island effect means London bedrooms can stay uncomfortably warm on summer nights.
Top-floor flats in Wimbledon feel the heat most, because the roof sits right above the bedroom. We cover Wimbledon as part of London, roughly 6 miles from central London. That includes the SW19 postcode district.

Guide prices show VAT at 20%.

Planning and permissions
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.
The survey
A survey in Wimbledon usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes. We book surveys in Wimbledon at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
