Air conditioning for extensions and kitchen-diners in Dumfries
An extension in Dumfries with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Mild Scottish summers mean cooling matters most in conservatories, lofts and rooms with large windows.
For a kitchen-diner in Dumfries, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. As well as Dumfries itself, our Dumfries and Galloway coverage takes in Annan, Castle Douglas and the towns around them. That includes the DG1 postcode district.
Prices in Dumfries
Budget around £1,345–£4,095 per space including VAT for air conditioning for extensions and kitchen-diners in and around Dumfries. It is a touch below the UK middle, as trade rates in Central and Southern Scotland tend to be. The biggest variables are the pipe route, access for the outdoor unit and the state of the consumer unit, all of which the survey settles. On our Central and Southern Scotland figures, the Large single option (one 5–7 kW unit for a large glazed space) is about £1,895–£2,595.
Single unit
One 3.5–5 kW unit for a medium extension.
Large single
One 5–7 kW unit for a large glazed space.
Twin units
Two indoor units on a multi-split for long or L-shaped spaces.
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.
The survey
On a survey in Dumfries the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows. We book surveys in Dumfries at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
