Boiler Upgrade Scheme Grants

Get £7,500 off your heat pump installation

Through the government’s Boiler Upgrade Scheme, you can get a £7,500 grant towards your installation.

At Cosier, we make it easy to switch from a gas or oil boiler to a heat pump. Because we’re an MCS-certified installer, we apply for the Boiler Upgrade Scheme grant on your behalf and handle all the admin — so you simply pay the difference above £7,500.

Some eligibility requirements apply, but most residential properties in England and Wales meet the requirements.

Am I eligible for the Boiler Upgrade Scheme grant?

Most properties are eligible, and we’ll always confirm before you commit. The main criteria are:

  • The property must be in England or Wales.
  • It can be a house, flat, or commercial building (shop, office, restaurant).
  • The existing heating system must be fossil fuel (gas, oil, LPG, coal) or direct-electric heating (storage heaters, electric panel heaters, or electric boilers).
  • The property owner must apply (it’s fine if you have a mortgage).
    • Landlords can apply for rental properties. If you’re a tenant, we’ll need to speak to your landlord as well.
  • Self-build homes – where you’re building the property for yourself – are eligible if they’ve never had a heating system installed.
  • Social housing and shared-ownership (part-buy / part-rent) properties aren’t eligible — there are separate schemes for those.

There are a couple of other conditions:

  • We need to remove the existing heating system (such as your gas boiler or electric heaters). However, we can usually reuse the existing radiators and pipework.
  • You can’t keep a fossil boiler alongside the heat pump as a backup, as these “hybrid” systems aren’t eligible. But don’t worry – we’ll design your heat pump system to be powerful enough to keep your house warm on the coldest days with no backup needed.

What you’ll need before applying

Before applying for the grant, your property needs an Energy Performance Certificate (EPC) that’s less than 10 years old.

If your home has been sold or rented recently, you probably already have one – you can check here for free.

If you don’t have an EPC already, we can help you arrange it. A new EPC typically costs £60–£120. An assessor will visit your home for up to an hour, then upload your certificate to the government website, which we’ll use to apply for your grant.

Sometimes the EPC will recommend improvements such as loft or cavity wall insulation. You don’t need to complete these before installing a heat pump, but adding insulation can improve efficiency and lower your bills. We’ll discuss what’s worthwhile when designing your heating system.

What types of heat pump are eligible?

The grant covers air-to-water heat pumps – systems that heat water for your radiators, underfloor heating, and hot-water cylinder.

It doesn’t currently cover:

  • Air-to-air systems (wall-mounted units that blow warm or cold air, like you see in hotels)
  • Systems that also cool your home

The scheme also covers ground-source heat pumps and biomass boilers (in some cases), but we do not install these.

Why apply through Cosier?

  • We’re MCS-certified and registered with the Boiler Upgrade Scheme.
  • We handle all the paperwork and admin for you.
  • We give clear, transparent quotes that show the grant amount and what you’ll pay personally.
  • If something about your property doesn’t qualify, we’ll tell you upfront and explain your options.
