Air source heat pump installation for Hammersmith homes
Most homes can run on a heat pump if the system is designed properly, and Hammersmith is no different. The key is matching the heat pump and radiators to the home's heat loss.
Terraced streets in Hammersmith often mean a compact unit position at the rear, so siting and sound levels are checked carefully. Homeowners across Greater London can arrange a survey in Hammersmith for a room-by-room design and a written quote before committing to anything.
We survey your home, design a heat pump system around its real heat loss, and manage the installation from the first visit to the MCS certificate.
- Homes replacing a gas, oil, LPG or electric heating system
- Owners who want one contract covering design, fitting and paperwork
- Households with room for a hot water cylinder
What's included
- Commissioning, handover and a walk-through of the controls
- Radiator and pipework changes where the design needs them
- Outdoor unit, hot water cylinder and weather compensation controls
- System design, unit sizing and a written quote
- Removal of the old boiler or heaters
Many homes in Hammersmith have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows.
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?
Hammersmith sees roughly 7 hours 50 minutes of daylight in late December against 16 hours 38 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.

Air source heat pump installation in Hammersmith: questions
Do you cover Notting Hill as well as Hammersmith?
Yes. We arrange surveys and installation in Notting Hill, which is about a mile north-east of Hammersmith, and across Greater London.
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 soon can you survey a home in Hammersmith?
Survey dates depend on how busy installers are in Greater London. We offer the next available dates when you enquire and confirm them in writing.
How long does an air source heat pump installation take?
A typical home installation takes 2–4 days on site. It takes longer if several radiators are being replaced, pipework is being upgraded or the cylinder is going in a new location. Your quote sets out the expected programme, including when you will be without heating and hot water. Timings are typical rather than fixed, because older homes sometimes reveal surprises once floorboards are lifted.
Will an air source heat pump be noisy?
Heat pumps are designed to run quietly, but where the unit sits makes a real difference. The survey looks for a position away from bedroom windows and neighbours, with clear airflow, and the installation must pass the MCS noise assessment. The fan is most noticeable on very cold days when the unit works hardest, and a little vapour during the periodic defrost is normal.
