Air conditioning for extensions and kitchen-diners across Cambridgeshire
For a kitchen-diner in Peterborough, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. An extension in Peterborough with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Low rainfall and long summer days in the East of England make south-facing rooms the first to overheat.

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
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. A survey in Cambridgeshire usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes.
