Before you book: air source heat pump installation in Feltham
In Feltham, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
In Feltham, cylinder space is planned with you, often in an airing cupboard, utility room or garage. Homeowners across Greater London can arrange a survey in Feltham 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.
- Households with room for a hot water cylinder
- Owners who want one contract covering design, fitting and paperwork
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
What's included
- Commissioning, handover and a walk-through of the controls
- System design, unit sizing and a written quote
- Boiler Upgrade Scheme application in England and Wales where eligible
- Free home survey and room-by-room heat loss calculation
- MCS registration and certificate, plus network operator notification
Terraced streets in Feltham often mean a compact unit position at the rear, so siting and sound levels are checked carefully.
Grants and rules for heat pumps in England
Homes in Feltham 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.

Winter daylight and heating in Feltham
On the shortest day Feltham 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 source heat pump installation in Feltham: questions
Where would the outdoor unit go on a Feltham 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 Feltham home.
Do you cover Hounslow as well as Feltham?
Yes. We arrange surveys and installation in Hounslow, which is about 3 miles north-east of Feltham, and across Greater London.
How long does installation take in Feltham?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Feltham home states the expected time.
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.
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.
