What to know about heat pump grants in Corby
Most homes can run on a heat pump if the system is designed properly, and Corby is no different. The key is matching the heat pump and radiators to the home's heat loss.
Oil and LPG-heated homes around Corby can have their options set out alongside the cost of a full system. Across Corby and Northamptonshire, 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.
- Anyone unsure which scheme applies and wanting it checked before committing

Grants and rules for heat pumps in England
Homes in Corby 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.

Short winter days in Corby and what they mean
Corby has about 7 hours 39 minutes of daylight at midwinter and 16 hours 50 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.
From survey to switch-on in Corby
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Corby 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 Corby: questions
What size heat pump does a Corby 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 Corby home.
How long does installation take in Corby?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Corby home states the expected time.
How long does a heat pump survey take in Corby?
A home survey in Corby 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.
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.
