Before you book: heat pump grants in Aylesbury
The question for an Aylesbury home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
Installation dates in Aylesbury are fixed around any funding confirmation, so work does not start too early. We confirm at the survey which funding route a home in Aylesbury is likely to qualify for.
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
- 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
- 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
- MCS certificate and handover documents after installation
- Installation scheduled around your grant confirmation or funding offer
For landlords with property in Aylesbury, we explain the funding position for each home before quoting.
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 Aylesbury quote.
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 Aylesbury's winters
On the shortest day Aylesbury gets about 7 hours 46 minutes of daylight, with the noon sun around 15° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.
How installation works in Aylesbury
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Aylesbury; 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 Aylesbury: questions
Do I need new radiators for a heat pump in Aylesbury?
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 Aylesbury home gives a room-by-room list.
Do you cover Princes Risborough as well as Aylesbury?
Yes. We arrange surveys and installation in Princes Risborough, which is about 6 miles south of Aylesbury, and across Buckinghamshire.
What size heat pump does an Aylesbury 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 Aylesbury home.
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.
