Wall-mounted air conditioning across London

In a semi or terrace in Westminster, the indoor unit often goes on a back bedroom wall with the outdoor unit on a bracket below. A single wall-mounted unit is often all a bedroom or sunny living room in Westminster needs. The urban heat island effect means London bedrooms can stay uncomfortably warm on summer nights.

Prices in London

Wall-mounted air conditioning in London typically comes in at £1,495–£3,895 per room including VAT, based on London rates. London is one of the dearer parts of the UK for trades, which shows in the range. The biggest variables are the pipe route, access for the outdoor unit and the state of the consumer unit, all of which the survey settles. For reference, the Popular option in London (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

For most houses in London, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.

The survey

We book surveys in London at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. A survey in London 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.

FAQ

Wall-mounted air conditioning in London

Will the outdoor unit need planning permission in London?

Most houses can have an outdoor unit under permitted development if it meets the size, number and MCS 020(a) noise conditions. Flats and listed buildings usually need permission or consent. We check on survey.

Which parts of London do you cover?

All of London, including Islington, Westminster, Bexley and Barking. Each district has its own page below with local details.

Is the survey free?

Yes, for new installations on the mainland. The survey and written quote are free and there is no obligation.

How much does wall-mounted air conditioning cost in London?

Our London guide range is £1,495–£3,895 per room, including VAT.

How long does a wall-mounted air conditioner take to fit?

Most single-room systems are fitted and commissioned in one day. The engineers drill one hole, fix both units, run the pipework, pressure test and vacuum the system, then commission it and show you how it works.

Can it heat as well as cool?

Yes. Almost every split system sold today is a reversible heat pump, so it heats efficiently in winter as well as cooling in summer.
