The reason why most households haven't been able to secure the £7,500 grant for heat pumps remains unclear.
The UK government's Boiler Upgrade Scheme (BUS) aims to encourage homeowners to switch from fossil fuel heating to low-carbon options like heat pumps or biomass boilers. However, the scheme's complexity and eligibility requirements may be deterring some households from participating.
The BUS offers grants of up to £6,000 for eligible homeowners replacing fossil fuel heating systems. Yet, to qualify, applicants must own their property, have an Energy Performance Certificate (EPC) with no outstanding recommendations, and meet an installation capacity limit of up to 45kWth. These criteria add layers of complexity that can create barriers for certain households.
Other schemes like ECO4 focus on low-income or vulnerable households, with strict eligibility requirements tied to income, benefits, or local council conditions. This targeted approach means many households do not qualify for full funding or appropriate grants to install heat pumps through these programs.
Navigating multiple overlapping programs with differing requirements and grant limits can be confusing for homeowners, potentially discouraging engagement or causing delays in adoption. A recent analysis by Nesta found that many households gave up on applying for the Boiler Upgrade Scheme due to a maze of paperwork and poor advice.
The Heat Pump Association has stressed that meaningful growth in low-carbon heating will only come if electricity pricing and financing models are rebalanced to make them competitive with gas. They welcomed the government's recent announcement to reshape the Boiler Upgrade Scheme, calling it a "positive step."
The government's consultation proposes changes such as expanding the list of supported technologies, like air-to-air heat pumps and thermal batteries. It also suggests allowing for leasing or subscription models instead of requiring homeowners to pay full installation costs upfront.
The relaxation of planning rules around heat pump installations is another step towards making low-carbon heating more accessible. Previously, up to 40% of heat pump installation projects were held back by planning permissions. Now, planning permissions near property boundaries are closer to 5-10%.
Despite these changes, many households still face barriers accessing the Boiler Upgrade Scheme. With the UK Government's confirmation of £1.545 billion in Boiler Upgrade Scheme funding through to 2028, it is crucial that the scheme remains accessible to homeowners for the government to meet its goal of 600,000 heat pumps each year.
Aira's research shows a 54% increase in grant applications for heat pumps during early 2025 due to the rule change. Yet, some households reported paying over £1,000 in fees just to have installers handle grant paperwork.
As the UK moves towards a greener future, simplifying the Boiler Upgrade Scheme and making it more accessible to a wider range of households will be key to achieving the government's targets for low-carbon heating adoption.
