Air conditioning for extensions and kitchen-diners in Crowthorne
In Crowthorne, a side wall of a single-storey extension is usually the neatest place for the indoor unit. In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon.
For a kitchen-diner in Crowthorne, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Crowthorne sits around 10 miles from Reading, inside our Berkshire area. Coverage includes RG45.

What moves a quote in Crowthorne up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. As an example, the Large single option (one 5–7 kW unit for a large glazed space) would typically be £2,495–£3,495 here.

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.
The survey
A survey in Crowthorne 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. 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.
