Wall-mounted air conditioning in County Durham

Wall-mounted air conditioning across County Durham

Where a home in Durham faces the street, the outdoor unit usually goes at the rear, out of sight. A single wall-mounted unit is often all a bedroom or sunny living room in Durham needs. In the North East, sizing for winter heating and then checking summer cooling usually gives the right system.

Prices in County Durham

In North East England, our guide range for wall-mounted air conditioning is £1,045–£2,695 per room, including VAT. It is a touch below the UK middle, as trade rates in North East England tend to be. What moves a quote in County Durham up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. On our North East England figures, the Popular option (quieter mid-range unit with Wi-Fi control and better seasonal efficiency for a living room) is about £1,445–£1,995.

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.
