Wall-mounted air conditioning across Devon
A single wall-mounted unit is often all a bedroom or sunny living room in Plymouth needs. Where a home in Plymouth faces the street, the outdoor unit usually goes at the rear, out of sight. In the South West, a system that heats well through damp winters is often as valuable as summer cooling.
Prices in Devon
Wall-mounted air conditioning in Devon typically comes in at £1,150–£2,950 per room including VAT, based on South West England rates. That is close to the UK middle for this kind of work. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. Typical Popular work (quieter mid-range unit with Wi-Fi control and better seasonal efficiency for a living room) lands around £1,550–£2,150 in this area.

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
On a survey in Devon 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. A survey in Devon 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.
