Ducted air conditioning in Heston
Ducted systems suit Heston loft conversions and new extensions where ceilings are being boarded anyway. 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.
In an older house in Heston, the loft and any existing bulkheads decide whether a ducted layout will work. Heston is about 11 miles from central London and falls within our London coverage. Coverage includes TW5.

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.

We book surveys in Heston at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. 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.
