Air-to-air heat pumps in Hounslow
Ask at your Hounslow survey whether the Boiler Upgrade Scheme grant could apply to your home. Many London homes are flats or tall terraces, where heat rises to the top floor and the bedrooms bear the brunt of a hot spell.
Homes in Hounslow on electric, oil or LPG heating are the ones most likely to benefit from an air-to-air heat pump. Our London coverage takes in Hounslow, about 10 miles from central London. We cover TW3, TW4 and TW6 and the streets around them.
Prices in Hounslow
Our London guide price for air-to-air heat pumps is £3,895–£15,095 for 2–5 rooms, VAT included. Prices here sit above the national middle, reflecting London labour rates and parking and access costs. Longer or hidden pipe runs, high-level brackets and electrical upgrades are the usual reasons a quote lands at the top of the range. Typical Small home work (three or four rooms heated and cooled) lands around £5,845–£9,845 in this area.
Two rooms
Living room and main bedroom on one outdoor unit.
Small home

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
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.
If your home in Hounslow is replacing fossil fuel or electric heating, and no gas, oil or LPG boiler stays in use, an MCS-certified air-to-air heat pump may qualify for the £2,500 Boiler Upgrade Scheme grant, which the MCS-certified installer claims and deducts from the price.
The survey
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. A survey in Hounslow 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.
