Wall-mounted air conditioning in Derby
A single wall-mounted unit is often all a bedroom or sunny living room in Derby needs. East Midlands summers bring dry, sunny spells, so glazing and orientation matter most when sizing a unit.
In a semi or terrace in Derby, the indoor unit often goes on a back bedroom wall with the outdoor unit on a bracket below. We cover Derby and the rest of Derbyshire, including Chesterfield and Long Eaton. Coverage includes DE1.
Prices in Derby
Wall-mounted air conditioning in Derby typically comes in at £1,095–£2,845 per room including VAT, based on East Midlands rates.

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
The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote. Surveys in Derby cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
