What to know about heat pump grants in Weymouth
Every property in Weymouth is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
Homeowners in Weymouth get a clear written quote showing the full price and any funding that applies. Installation dates in Weymouth 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
- MCS certificate and handover documents after installation
- 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)
- Eligibility check for the scheme that covers your nation
For landlords with property in Weymouth, we explain the funding position for each home before quoting.
Grants and rules for heat pumps in England
Homes in Weymouth 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 Weymouth
Weymouth sees roughly 7 hours 58 minutes of daylight in late December against 16 hours 29 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 Weymouth
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Weymouth home, measures every room and checks where the outdoor unit can go.
- You receive a heat loss design and a fixed written quote, with any grant shown where it applies.
- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Heat pump grants in Weymouth: questions
Do I need new radiators for a heat pump in Weymouth?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Weymouth home gives a room-by-room list.
What size heat pump does a Weymouth 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 Weymouth home.
Do you cover Dorchester as well as Weymouth?
Yes. We arrange surveys and installation in Dorchester, which is about 7 miles north of Weymouth, and across Dorset.
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.
