Air conditioning for extensions and kitchen-diners in Reading
In Reading, a side wall of a single-storey extension is usually the neatest place for the indoor unit. The South East sees some of the UK's warmest summer days, and south-facing rooms and conservatories feel it first.
For a kitchen-diner in Reading, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. We cover Reading and the rest of Berkshire, including Slough and Bracknell. Coverage includes RG1, RG6 and RG30.

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
Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.
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 Reading cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
