Ducted air conditioning across London

In an older house in Westminster, the loft and any existing bulkheads decide whether a ducted layout will work. For a renovation in Westminster, the best time to plan ducted cooling is before the plasterers arrive. London's dense streets hold heat overnight, so top-floor flats and loft rooms often stay warm long after sunset.

Prices in London

Budget around £7,195–£19,745 per system including VAT for ducted air conditioning in and around London. Prices here sit above the national middle, reflecting London labour rates and parking and access costs. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. As an example, the Zoned option (motorised dampers or two units for separate floors or room groups) would typically be £9,845–£14,445 here.

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

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. On a survey in London the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.

FAQ

Ducted 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.

Is the survey free?

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

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.

How much does ducted air conditioning cost in London?

Our London guide range is £7,195–£19,745 per system, including VAT.

Is ducted more expensive than wall units?

Yes, usually by 30–60% for the same rooms, because of the ductwork and building work. In return there is nothing on the walls and it is very quiet.

Do the ducts lose cooling?

Properly insulated and sealed ducts lose very little. We keep runs short and insulate everything in the loft.
