Air conditioning for extensions and kitchen-diners in Falmouth
Damp South West winters make the dehumidifying side of a heat pump almost as useful as its cooling. In Falmouth, a side wall of a single-storey extension is usually the neatest place for the indoor unit.
For a kitchen-diner in Falmouth, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Falmouth lies roughly 8 miles from Truro, and we cover it as part of Cornwall. Postcode districts we cover here include TR11.
Prices in Falmouth
Air conditioning for extensions and kitchen-diners in Falmouth typically comes in at £1,450–£4,450 per space including VAT, based on South West England rates. That is close to the UK middle for this kind of work. 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. As an example, the Large single option (one 5–7 kW unit for a large glazed space) would typically be £2,050–£2,850 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
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.
The survey
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. On a survey in Falmouth 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.
