What to know about air-to-air heat pumps in Hounslow
A heat pump suits most Hounslow homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Top-floor rooms in Hounslow that overheat in summer gain from the cooling an air-to-air system provides. Installers in Hounslow plan condensate drains and pipe covers so indoor and outdoor runs stay neat.
An air-to-air heat pump warms rooms directly with air, and can cool them in summer, but it does not heat your hot water.
- Households that already have, or will add, a separate source of hot water
- Homes where fitting radiators and pipework would be very disruptive
- Rooms that get too hot in summer as well as cold in winter
What's included
- Free survey covering rooms to heat, unit positions and hot water options
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Commissioning, MCS certificate and the air-to-air grant claim in England and Wales where eligible
- Electrical supply and controls set up for each room
- Outdoor unit and indoor units for each room
A survey in Hounslow covers indoor unit positions, pipe routes and hot water for homes across Greater London.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Hounslow quote.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.

Air-to-air heat pumps in Hounslow: questions
Where would the outdoor unit go on a Hounslow house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Hounslow home.
Do you cover Twickenham as well as Hounslow?
Yes. We arrange surveys and installation in Twickenham, which is about 2 miles south-east of Hounslow, and across Greater London.
How long does installation take in Hounslow?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Hounslow home states the expected time.
How do I look after an air-to-air system?
Clean the indoor unit filters regularly, typically every few weeks during heavy use and following the manufacturer's guidance, and keep the outdoor unit clear of leaves and snow. Annual servicing is recommended and is often a condition of the manufacturer's warranty. Any work on the refrigerant circuit must be done by an F-gas certified engineer.
Can an air-to-air heat pump heat my water?
No. An air-to-air heat pump heats and cools the air in rooms but does not produce hot water. You need a separate source, such as an existing immersion cylinder, a hot water heat pump or an electric water heater. If you want one system for heating and hot water, an air-to-water heat pump with a cylinder is the alternative.
