Air conditioning for extensions and kitchen-diners in Cinderford
For a kitchen-diner in Cinderford, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. In the South West, a system that heats well through damp winters is often as valuable as summer cooling.
An extension in Cinderford with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. We cover Cinderford as part of Gloucestershire, roughly 11 miles from Gloucester. Postcode districts we cover here include GL14.

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.

Surveys in Cinderford cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. We book surveys in Cinderford at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
