Air conditioning for extensions and kitchen-diners in Croydon
London's dense streets hold heat overnight, so top-floor flats and loft rooms often stay warm long after sunset. For a kitchen-diner in Croydon, we place the indoor unit clear of the hob and plan the outdoor unit at the rear.
In Croydon, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Croydon is about 8 miles from central London and falls within our London coverage. We cover CR0, CR7 and CR9 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
For most houses in Croydon, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.
The survey
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. We book surveys in Croydon at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
