Before you book: heat pump grants in Caerphilly
A heat pump suits most Caerphilly homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
We confirm at the survey which funding route a home in Caerphilly is likely to qualify for. Installation dates in Caerphilly are fixed around any funding confirmation, so work does not start too early.
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
- Anyone unsure which scheme applies and wanting it checked before committing
- Landlords in England and Wales, who can apply for their let properties
What's included

Oil and LPG-heated homes around Caerphilly can have their options set out alongside the cost of a full system.
Grants and rules for heat pumps in Wales
Homes in Caerphilly can use the Boiler Upgrade Scheme, which applies in Wales as well as England: £7,500 towards an air source heat pump, or £9,000 when it replaces oil or LPG heating for installations from 21 July 2026 to 31 March 2027. The MCS-certified installer named in your quote applies and deducts the grant.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Wales has its own permitted development rules for air source heat pumps, so we check what applies to your property, including listed building and conservation-area constraints, at the survey.

Winter daylight and heating in Caerphilly
Caerphilly sees roughly 7 hours 49 minutes of daylight in late December against 16 hours 39 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.
The steps for heat pump grants in Caerphilly
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Caerphilly; 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 Caerphilly: questions
What size heat pump does a Caerphilly home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Caerphilly home.
Can you service a heat pump in Caerphilly that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Caerphilly, whoever fitted them. Tell us the make and model when you book.
How long does installation take in Caerphilly?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Caerphilly home states the expected time.
How much is the heat pump grant?
It depends on where you live. In England and Wales, the Boiler Upgrade Scheme pays £7,500 towards an air-to-water heat pump, or £9,000 when replacing oil or LPG heating for installations from 21 July 2026 to 31 March 2027. In Scotland, Home Energy Scotland offers up to £7,500, plus a rural uplift and an optional loan. Northern Ireland has no dedicated grant at present.
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.
