Air conditioning for extensions and kitchen-diners in Kilmarnock
An extension in Kilmarnock with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. In central and southern Scotland, heat pump heating is usually the main reason to install, especially in homes on electric heating.
For a kitchen-diner in Kilmarnock, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. As well as Kilmarnock itself, our Ayrshire coverage takes in Ayr, Irvine and the towns around them. Homes in KA3 are all within our coverage.
Prices in Kilmarnock
For Kilmarnock, expect roughly £1,345 to £4,095 per space, VAT included, adjusted for typical Central and Southern Scotland rates. Labour rates in Central and Southern Scotland keep this slightly under the national middle. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. As an example, the Large single option (one 5–7 kW unit for a large glazed space) would typically be £1,895–£2,595 here.
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 Kilmarnock 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. At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote.
