Air conditioning for extensions and kitchen-diners in Stranraer
Long Scottish heating seasons make efficiency in cold, damp weather the thing to design around. In Stranraer, a side wall of a single-storey extension is usually the neatest place for the indoor unit.
An extension in Stranraer with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Stranraer sits around 57 miles from Dumfries, inside our Dumfries and Galloway area. We cover DG9 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
Outdoor units on Scottish homes can often be installed without a planning application, but the conditions differ from England's, so we confirm the rules for your property at survey.
