Air source heat pump installation for Acton homes
Most homes can run on a heat pump if the system is designed properly, and Acton is no different. The key is matching the heat pump and radiators to the home's heat loss.
In Acton, cylinder space is planned with you, often in an airing cupboard, utility room or garage. Many homes in Acton have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows.
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.
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
- Houses with reasonable insulation, or a plan to improve it
- Homes replacing a gas, oil, LPG or electric heating system
What's included
- Commissioning, handover and a walk-through of the controls
- System design, unit sizing and a written quote
- Removal of the old boiler or heaters
- Boiler Upgrade Scheme application in England and Wales where eligible
- Radiator and pipework changes where the design needs them
Homeowners across Greater London can arrange a survey in Acton for a room-by-room design and a written quote before committing to anything.
Grants and rules for heat pumps in England
Homes in Acton 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.
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.

How long is the heating season in Acton?
On the shortest day Acton gets about 7 hours 49 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 source heat pump installation in Acton: questions
How long does installation take in Acton?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for an Acton home states the expected time.
Can you service a heat pump in Acton that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Acton, whoever fitted them. Tell us the make and model when you book.
Where would the outdoor unit go on an Acton 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 Acton home.
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.
Can I cancel after accepting the quote?
Nothing is ordered until you accept the written quote. Where the contract is agreed away from our premises, for example at your kitchen table, you can cancel within 14 days under the Consumer Contracts Regulations 2013. If you ask us to start sooner and then cancel, you pay only for work done up to that point.
