Air conditioning for extensions and kitchen-diners in Rosyth
Long Scottish heating seasons make efficiency in cold, damp weather the thing to design around. An extension in Rosyth with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon.
In Rosyth, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Our Fife coverage takes in Rosyth, about 3 miles from Dunfermline. Postcode districts we cover here include KY11.
Prices in Rosyth
Our Central and Southern Scotland guide price for air conditioning for extensions and kitchen-diners is £1,345–£4,095 per space, VAT included. It is a touch below the UK middle, as trade rates in Central and Southern Scotland tend to be. Longer or hidden pipe runs, high-level brackets and electrical upgrades are the usual reasons a quote lands at the top of the range. For reference, the Large single option in Rosyth (one 5–7 kW unit for a large glazed space) usually comes to 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
A survey in Rosyth usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes. We book surveys in Rosyth at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
