Air conditioning for extensions and kitchen-diners in Newbury
An extension in Newbury with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. The South East sees some of the UK's warmest summer days, and south-facing rooms and conservatories feel it first.
In Newbury, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Newbury lies roughly 16 miles from Reading, and we cover it as part of Berkshire. Postcode districts we cover here include RG14.

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
A survey in Newbury 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.
