Ducted air conditioning in Dagenham
For a renovation in Dagenham, 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.
In an older house in Dagenham, the loft and any existing bulkheads decide whether a ducted layout will work. Our London coverage takes in Dagenham, about 13 miles from central London. Coverage includes RM10.
Prices in Dagenham
Our London guide price for ducted air conditioning is £7,195–£19,745 per system, VAT included. 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. On our London figures, the Zoned option (motorised dampers or two units for separate floors or room groups) is about £9,845–£14,445.

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
A survey in Dagenham 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. 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.
