Bedroom and loft air conditioning in Chiswick
In London, heat soaks into brick and concrete during the day and comes back out at night, which is when it is hardest to sleep. For bedrooms in Chiswick, we place the outdoor unit at the back of the house, away from neighbours' windows.
Loft conversions and top-floor bedrooms in Chiswick gain heat through the roof all day and give it back at night. Chiswick sits around 6 miles from central London, inside our London area. We cover W4 and the streets around them.
Prices in Chiswick
Our London guide price for bedroom and loft air conditioning is £1,595–£3,895 per room, VAT included. That is above the UK middle, mainly because labour and access cost more in London. What moves a quote in Chiswick up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. For reference, the Popular option in Chiswick (low-noise unit with Wi-Fi for a loft room or main bedroom) usually comes to about £2,045–£2,895.

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.

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