Before you book: heat pump grants in Harrow
Most homes can run on a heat pump if the system is designed properly, and Harrow is no different. The key is matching the heat pump and radiators to the home's heat loss.
Oil and LPG-heated homes around Harrow can have their options set out alongside the cost of a full system. Across Harrow and Greater London, the paperwork for funding applications is prepared alongside your quote.
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.
- Homes in England and Wales on oil or LPG, where a higher grant applies between set dates
- 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
- Written quote showing the full price and any grant deduction
- Installation scheduled around your grant confirmation or funding offer
- Boiler Upgrade Scheme application made by the MCS-certified installer (England and Wales)
- MCS certificate and handover documents after installation
Installation dates in Harrow are fixed around any funding confirmation, so work does not start too early.
Grants and rules for heat pumps in England
Homes in Harrow 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.

Heat pump grants in Harrow: questions
Can you service a heat pump in Harrow that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Harrow, whoever fitted them. Tell us the make and model when you book.
How soon can you survey a home in Harrow?
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.
How long does a heat pump survey take in Harrow?
A home survey in Harrow 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.
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.
