Before you book: heat pump grants 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.
For landlords with property in Hounslow, we explain the funding position for each home before quoting. We confirm at the survey which funding route a home in Hounslow is likely to qualify for.
Heat pump funding depends on which UK nation you live in, so we confirm what applies to your home and handle the grant steps alongside your quote.
- Homeowners in England and Wales replacing gas, oil, LPG or electric heating
- Landlords in England and Wales, who can apply for their let properties
- Anyone unsure which scheme applies and wanting it checked before committing
What's included
- Eligibility check for the scheme that covers your nation
- Installation scheduled around your grant confirmation or funding offer
- Written quote showing the full price and any grant deduction
- Boiler Upgrade Scheme application made by the MCS-certified installer (England and Wales)
- MCS certificate and handover documents after installation
Installation dates in Hounslow are fixed around any funding confirmation, so work does not start too early.
Grants and rules for heat pumps in England
Homes in Hounslow 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.

Winter daylight and heating in Hounslow
Hounslow 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.
What happens after you enquire in Hounslow?
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Hounslow; the surveyor measures rooms, windows and radiators and looks at cylinder space.
- The design and quote arrive in writing, including radiator changes and the outdoor unit position.
- On installation days the old system is removed and the new one fitted and filled.
- We commission the heat pump, show you the controls and register the installation.
Heat pump grants in Hounslow: questions
Can you service a heat pump in Hounslow that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Hounslow, whoever fitted them. Tell us the make and model when you book.
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 soon can you survey a home in Hounslow?
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.
Do I need an EPC for the Boiler Upgrade Scheme?
No longer. Since 28 April 2026, a valid EPC is not required for the Boiler Upgrade Scheme in England and Wales. The system must still meet the home's full heating and hot water needs, which the room-by-room heat loss calculation confirms. The other eligibility rules, such as owning the property, still apply.
Who applies for the Boiler Upgrade Scheme?
In England and Wales, the MCS-certified installer applies to Ofgem for the Boiler Upgrade Scheme on your behalf, and the grant is deducted from your quote. Ofgem then contacts you as the property owner to confirm the details. Your quote names the MCS-certified installer for your job, so you know who is making the application.
