Get £2,500 - £9,000 off your heat pump

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 fuel heater 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, we need to provide the Boiler Upgrade Scheme with details of your current heating system. This can be photos of the existing system, an energy bill showing gas or oil usage, or an Energy Performance Certificate (EPC) that’s less than 10 years old. We’ll advise you on the evidence we need to provide.  

Sometimes an Energy Performance Certificate (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?

Air-to-air (A2A) heat pumps are more commonly known as air conditioning units. You’ve probably seen them in hotels or on holiday in warmer countries:

• They use fan units in each room to blow hot air to heat the room, or cold air to cool it down.
• They’re eligible for £2,500 grants, but only if you use them to heat/cool the whole property and replace your existing heating system. You must have a fan unit in each “habitable room” – that means bedrooms and living rooms, but not hallways, toilets or the kitchen. 
• It’s not an “air-con grant”: If you just want cooling in a single bedroom for the hottest nights in summer, it may be cheaper to pay out of pocket for a single unit, than to replace your whole heating system so that you can apply for the grant. 
• The grants are only available if you use an MCS-certified firm, like Cosier. If you’re speaking to air con specialists, always confirm if they are MCS certified and able to get the grants on your behalf. 

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.
