Boiler Upgrade Scheme
Check if you may qualify for the heat pump grant
The Boiler Upgrade Scheme can offer £7,500 towards eligible air-to-water heat pump installations in England and Wales. From 21 July 2026 to 31 March 2027, eligible off-gas homes using oil or LPG may qualify for the enhanced £9,000 grant.
This checker is a guide only. We will confirm eligibility before any grant application and the property owner must consent to the BUS application.

Our Heat Geek heat pump installation process
Click each step to see what happens and why it matters.
1. Initial enquiry and instant estimate
Use the Heat Geek estimate tool above. Pay securely on the Heat Geek website for your heat loss survey.
2. Home survey and heat-loss calculation
Liam Conneely will contact you to book in for a heat loss appointment, this includes scanning your property using Heat Geek Lidar scanning technology.
3. Zero Disrupt algorithm calculates the optimal system design
The Zero Disrupt algorithm uses advanced modeling to determine the most efficient heat pump system for your property, minimizing disruption during installation.
4. Hot water assessment
The Zero Disrupt algorithm also considers your hot water needs and existing cylinder, checking the running cost differences between keeping the existing or replacement.
5. Exceptional Installation standards
Heat Geek installation standards are high, and Vector Heat has a proven track record for tidy, careful work. Your heat pump will be installed with proper attention to design, commissioning and finish.
6. Commissioning and handover
The Heat Geek commissioning and handover process ensures your system is fully operational and you understand how to use it. Evidence is gathered and presented for your records.
Useful information
Heat Geek questions homeowners should understand
Clear advice on the details that actually affect performance.
Will I be able to see my heat loss design?
Yes, you will have access to your heat loss design and paperwork via the Heat Geek portal.
What is Zero Disrupt?
ZeroDisrupt™ is Heat Geek’s proprietary AI heating system designer that uses real-world data to eliminate unnecessary upgrades. By stripping out "design fat," it enables high-efficiency heat pump installations for approximately £3,000 (often cheaper than a traditional gas boiler replacement).
Will my bills be lower?
A well-designed heat pump uses less energy than a boiler, but electricity costs more per unit than gas. Running cost depends on efficiency, tariff, flow temperature, controls and how the home is used. That is why design and commissioning matter.
Green mortgages: how heat pumps unlock lower rates (2026)
Green mortgages offer a lower interest rate, or a cash incentive, on properties with an A or B EPC rating. Most UK homeowners don't currently qualify, but installing a heat pump typically improves an EPC rating, meaning your next remortgage could unlock a better deal. NatWest, HSBC, Barclays, Nationwide and others all offer green mortgage products in 2026. The savings aren't always dramatic, but they compound over a mortgage term and they're on top of any installation grants you've already claimed.
Mortgage cashback: how to unlock £2,000+ towards your heat pump (updated 2026)
Barclays: £2,000 cashback. Lloyds Bank: up to £1,000 Eco Home Reward. Halifax: up to £2,000 Green Living Reward. Nationwide: 0% interest green additional borrowing. Virgin Money: retrofit boost.
Jargon buster
Heat pump terms explained
Open the terms you want to understand.
Flow temperature
The temperature of the water leaving the heat pump and going to your radiators or underfloor heating. Lower flow temperature usually means better efficiency.
Weather compensation
A control method where the heat pump automatically changes the water temperature depending on the outdoor temperature. It helps the system run steadily and efficiently.
Heat loss
The amount of heat each room loses on a cold day. It tells us how much heat the system needs to put back into each room.
Emitter
The thing that emits heat into the room, usually a radiator, fan convector or underfloor heating circuit.
SCOP
Seasonal Coefficient of Performance. It is a seasonal efficiency figure. A SCOP of 4 means roughly 4 units of heat for every 1 unit of electricity over the season.
Buffer
A water vessel sometimes added to heat pump systems. Buffers can be useful in the right design, but unnecessary or badly piped buffers can reduce efficiency.
MCS
The certification scheme required for most grant-funded heat pump installations. It sets standards for design, installation and customer paperwork.
BUS grant
The Boiler Upgrade Scheme grant. It is applied for by the installer and deducted from the customer’s quote if the installation is eligible.

FAQs
Common heat pump questions
How long does a heat pump installation take?
Many installations take several days, but it depends on cylinder work, radiator upgrades, pipework routes and whether the existing system needs correcting first. We will explain disruption before the job starts.
Do I need planning permission?
Many domestic air source heat pumps are installed under permitted development, but there are limits and exceptions. We will check the basics during survey, especially if the property is listed, in a conservation area, or the unit location is tight.
Will the heat pump be noisy?
Modern units are generally quiet when located and commissioned properly. Noise depends on the unit, location, mounting, airflow and how hard the system has to work.
Do you install Vaillant, Worcester Bosch and other brands?
Yes. We work with quality heat pump equipment and design the system around the property, not just the badge on the outdoor unit.
Can you work with oil or LPG homes?
Yes. Oil and LPG homes are often strong candidates because running costs and grant support can make the switch more attractive, especially where the property is off the gas grid.
What should I send with an enquiry?
Send your postcode, current heating type, whether you own the property, photos of the boiler/cylinder/radiators and any quote or survey you already have. This helps us respond quickly.
