Air conditioning for extensions and kitchen-diners in Cambridge
An extension in Cambridge with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. The East of England is one of the sunniest and driest parts of the UK, which makes glazed rooms and lofts hard to keep cool.
For a kitchen-diner in Cambridge, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Cambridge sits around 30 miles from Peterborough, inside our Cambridgeshire area. Coverage includes CB5, CB21, CB22, CB23 and CB24.

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