What to know about air-to-air heat pumps in Hammersmith
A heat pump suits most Hammersmith homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
A survey in Hammersmith covers indoor unit positions, pipe routes and hot water for homes across Greater London. Flats in Hammersmith on storage or panel heaters can often switch to air-to-air without fitting radiators or pipework.
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.
- Extensions, conservatories and garden rooms
- Households that already have, or will add, a separate source of hot water
- Rooms that get too hot in summer as well as cold in winter
What's included
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Electrical supply and controls set up for each room
- Condensate drains and neat external pipe covers
- Free survey covering rooms to heat, unit positions and hot water options
- Commissioning, MCS certificate and the air-to-air grant claim in England and Wales where eligible
Top-floor rooms in Hammersmith that overheat in summer gain from the cooling an air-to-air system provides.
Grants and rules for heat pumps in England
Homes in Hammersmith can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.

How long is the heating season in Hammersmith?
On the shortest day Hammersmith gets about 7 hours 50 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Air-to-air heat pumps in Hammersmith: questions
Can you service a heat pump in Hammersmith that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Hammersmith, whoever fitted them. Tell us the make and model when you book.
Where would the outdoor unit go on a Hammersmith 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 Hammersmith home.
How long does installation take in Hammersmith?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Hammersmith home states the expected time.
Can air-to-air heat pumps cool as well as heat?
Yes. Most air-to-air systems can reverse their cycle to cool and dehumidify rooms in summer, which makes them useful for loft rooms, south-facing extensions and home offices that overheat. Cooling uses electricity, so running costs rise if it is used heavily. You control heating and cooling for each room separately.
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.
