Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Carshalton quote.
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.

Designing for Carshalton's winters
On the shortest day Carshalton gets about 7 hours 51 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.
The steps for heat pump grants in Carshalton
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Carshalton; 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 Carshalton: questions
How long does a heat pump survey take in Carshalton?
A home survey in Carshalton usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
Do you cover Sutton as well as Carshalton?
Yes. We arrange surveys and installation in Sutton, which is about a mile west of Carshalton, and across Greater London.
How long does installation take in Carshalton?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Carshalton home states the expected time.
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.
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.
