Design-led and low-profile air conditioning in Isleworth
Design-led units suit Isleworth homes with feature walls or open-plan rooms where the unit is always in view. 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.
In Isleworth, a flat-fronted unit is a neat way to add cooling to a living room without a bulky white box. Isleworth is about 10 miles from central London and falls within our London coverage. Coverage includes TW7.

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
On a survey in Isleworth 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. A survey in Isleworth 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.
