Bedroom and loft air conditioning in Hanworth
Loft conversions and top-floor bedrooms in Hanworth 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.
For bedrooms in Hanworth, we place the outdoor unit at the back of the house, away from neighbours' windows. Hanworth is about 12 miles from central London and falls within our London coverage. We cover TW13 and the streets around them.

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
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 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 Hanworth cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
