What to know about heat pump grants in Marlow
Every property in Marlow 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.
For landlords with property in Marlow, we explain the funding position for each home before quoting. Installation dates in Marlow 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
- Homes in England and Wales on oil or LPG, where a higher grant applies between set dates
- Anyone unsure which scheme applies and wanting it checked before committing

Across Marlow and Buckinghamshire, the paperwork for funding applications is prepared alongside your quote.
Grants and rules for heat pumps in England
Homes in Marlow 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.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.

Designing for Marlow's winters
On the shortest day Marlow gets about 7 hours 49 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 Marlow
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Marlow 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 Marlow: questions
Do you cover High Wycombe as well as Marlow?
Yes. We arrange surveys and installation in High Wycombe, which is about 4 miles north of Marlow, and across Buckinghamshire.
How long does a heat pump survey take in Marlow?
A home survey in Marlow 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.
How soon can you survey a home in Marlow?
Survey dates depend on how busy installers are in Buckinghamshire. We offer the next available dates when you enquire and confirm them in writing.
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.
