Air conditioning for extensions and kitchen-diners in Thatcham
Hot spells reach the South East early, which makes spring the easiest time to arrange an installation. For a kitchen-diner in Thatcham, we place the indoor unit clear of the hob and plan the outdoor unit at the rear.
An extension in Thatcham with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Thatcham is about 13 miles from Reading and falls within our Berkshire coverage. Coverage includes RG18.

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