Air conditioning for extensions and kitchen-diners in Matlock
East Midlands summers bring dry, sunny spells, so glazing and orientation matter most when sizing a unit. In Matlock, a side wall of a single-storey extension is usually the neatest place for the indoor unit.
An extension in Matlock with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Matlock is about 15 miles from Derby and falls within our Derbyshire coverage. We cover DE4 and the streets around them.
Prices in Matlock
Guide prices around Matlock run from £1,395 to £4,245 per space including VAT. It is a touch below the UK middle, as trade rates in the East Midlands tend to be.

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
Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.
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. A survey in Matlock 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.
