Ducted air conditioning in Northolt
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 Northolt, the loft and any existing bulkheads decide whether a ducted layout will work.
For a renovation in Northolt, the best time to plan ducted cooling is before the plasterers arrive. Our London coverage takes in Northolt, about 11 miles from central London. That includes the UB5 postcode district.
Prices in Northolt
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. 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. Typical Zoned work (motorised dampers or two units for separate floors or room groups) lands around £9,845–£14,445 in this area.

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 Northolt, 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 Northolt at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. On a survey in Northolt 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.
