Ducted air conditioning in Coulsdon
Many London homes are flats or tall terraces, where heat rises to the top floor and the bedrooms bear the brunt of a hot spell. For a renovation in Coulsdon, the best time to plan ducted cooling is before the plasterers arrive.
Ducted systems suit Coulsdon loft conversions and new extensions where ceilings are being boarded anyway. Coulsdon lies roughly 12 miles from central London, and we cover it as part of London. We cover CR5 and the streets around them.

Guide prices around Coulsdon run from £7,195 to £19,745 per system including VAT. That is above the UK middle, mainly because labour and access cost more in London. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs.

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
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.

At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote. We book surveys in Coulsdon at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
