Air-to-air heat pumps in Isleworth
Homes in Isleworth on electric, oil or LPG heating are the ones most likely to benefit from an air-to-air heat pump. London's dense streets hold heat overnight, so top-floor flats and loft rooms often stay warm long after sunset.
We size every heat pump in Isleworth for a cold winter day, then check the cooling side is right for summer. Isleworth is about 10 miles from central London and falls within our London coverage. Homes in TW7 are all within our coverage.
Prices in Isleworth

What moves a quote in Isleworth up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed.

Prices are shown before any Boiler Upgrade Scheme grant. The £2,500 air-to-air grant applies only to eligible homes in England and Wales, using an MCS-certified heat pump installed by an MCS-certified installer, who applies for the grant and deducts it from the price. We confirm eligibility, and which installer applies, before you commit.
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
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
Isleworth is in the Boiler Upgrade Scheme area, so eligible homes replacing oil, gas, LPG or electric heating may be able to get £2,500 off an air-to-air heat pump, as long as no fossil-fuel boiler stays in use. An MCS-certified installer must claim it; we confirm eligibility, and which installer applies, before you commit.
The survey
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. Surveys in Isleworth cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
