Ducted air conditioning in Hounslow
Ducted systems suit Hounslow loft conversions and new extensions where ceilings are being boarded anyway. The urban heat island effect means London bedrooms can stay uncomfortably warm on summer nights.
For a renovation in Hounslow, the best time to plan ducted cooling is before the plasterers arrive. Hounslow lies roughly 10 miles from central London, and we cover it as part of London. That includes the TW3, TW4 and TW6 postcode districts.
Prices in Hounslow
Ducted air conditioning in Hounslow typically comes in at £7,195–£19,745 per system including VAT, based on London rates. That is above the UK middle, mainly because labour and access cost more in London. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. For reference, the Zoned option in Hounslow (motorised dampers or two units for separate floors or room groups) usually comes to about £9,845–£14,445.

Guide prices show VAT at 20%.

Planning and permissions
For most houses in Hounslow, 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
Surveys in Hounslow cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote.
