Air conditioning for extensions and kitchen-diners in Yeovil
In Yeovil, a side wall of a single-storey extension is usually the neatest place for the indoor unit. In the South West, a system that heats well through damp winters is often as valuable as summer cooling.
An extension in Yeovil with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. We cover Yeovil as part of Somerset, roughly 21 miles from Taunton. Homes in BA20 are all within our coverage.

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
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. A survey in Yeovil 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.
