Heat pump grants for Harpenden homes
Most homes can run on a heat pump if the system is designed properly, and Harpenden is no different. The key is matching the heat pump and radiators to the home's heat loss.
Homeowners in Harpenden get a clear written quote showing the full price and any funding that applies. Installation dates in Harpenden 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.
- Landlords in England and Wales, who can apply for their let properties
- Homeowners in England and Wales replacing gas, oil, LPG or electric heating
- Homes in England and Wales on oil or LPG, where a higher grant applies between set dates
What's included
- Installation scheduled around your grant confirmation or funding offer
- MCS certificate and handover documents after installation
- Eligibility check for the scheme that covers your nation
- Boiler Upgrade Scheme application made by the MCS-certified installer (England and Wales)
- Written quote showing the full price and any grant deduction
We confirm at the survey which funding route a home in Harpenden is likely to qualify for.
Grants and rules for heat pumps in England
Homes in Harpenden 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.

Short winter days in Harpenden and what they mean
Harpenden has about 7 hours 46 minutes of daylight at midwinter and 16 hours 42 minutes at midsummer. That swing matters if you pair a heat pump with solar panels: summer generation can cover much of the hot water, winter generation far less.
The steps for heat pump grants in Harpenden
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Harpenden; 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 Harpenden: questions
Do you cover St Albans as well as Harpenden?
Yes. We arrange surveys and installation in St Albans, which is about 5 miles south of Harpenden, and across Hertfordshire.
Can you service a heat pump in Harpenden that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Harpenden, whoever fitted them. Tell us the make and model when you book.
Do I need new radiators for a heat pump in Harpenden?
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 Harpenden home gives a room-by-room list.
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.
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.
