Air conditioning for extensions and kitchen-diners in Preston
In Preston, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Damp North West weather makes the dehumidifying mode of a modern split system genuinely useful for much of the year.
For a kitchen-diner in Preston, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Preston is one of the main towns we cover in Lancashire, alongside Burnley and Blackburn. We cover PR0, PR1 and PR11 and the streets around them.

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.
