Air conditioning for extensions and kitchen-diners in Blackburn
In the North West, heating efficiency is often the main benefit, with summer cooling a welcome bonus. For a kitchen-diner in Blackburn, we place the indoor unit clear of the hob and plan the outdoor unit at the rear.
In Blackburn, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Blackburn is about 9 miles from Preston and falls within our Lancashire coverage. Homes in BB1 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.

Planning and permissions
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.
