Wall-mounted air conditioning in Morden
Where a home in Morden faces the street, the outdoor unit usually goes at the rear, out of sight. In London, heat soaks into brick and concrete during the day and comes back out at night, which is when it is hardest to sleep.
A single wall-mounted unit is often all a bedroom or sunny living room in Morden needs. We cover Morden as part of London, roughly 8 miles from central London. Postcode districts we cover here include SM4.
Prices in Morden
Budget around £1,495–£3,895 per room including VAT for wall-mounted air conditioning in and around Morden. That is above the UK middle, mainly because labour and access cost more in London. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. For reference, the Popular option in Morden (quieter mid-range unit with Wi-Fi control and better seasonal efficiency for a living room) usually comes to about £2,045–£2,845.

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.
