Air conditioning for extensions and kitchen-diners across the Highlands
In Inverness, a side wall of a single-storey extension is usually the neatest place for the indoor unit. An extension in Inverness with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Here, heat pumps are sized for low winter temperatures and exposed sites.
Prices in the Highlands
Our Highlands, Islands and North East Scotland guide price for air conditioning for extensions and kitchen-diners is £1,295–£3,945 per space, VAT included. It is a touch below the UK middle, as trade rates in the Highlands, Islands and North East Scotland tend to be. What moves a quote in the Highlands up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. On our Highlands, Islands and North East Scotland figures, the Large single option (one 5–7 kW unit for a large glazed space) is about £1,795–£2,545.

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
We book surveys in the Highlands at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. On a survey in the Highlands 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.
