Ducted air conditioning in Hornchurch
London's dense streets hold heat overnight, so top-floor flats and loft rooms often stay warm long after sunset. For a renovation in Hornchurch, the best time to plan ducted cooling is before the plasterers arrive.
Ducted systems suit Hornchurch loft conversions and new extensions where ceilings are being boarded anyway. Hornchurch lies roughly 15 miles from central London, and we cover it as part of London. Homes in RM11 and RM12 are all within our coverage.

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.
