The UK government faces criticism over its expenditure on heat pump subsidies, with claims that approximately £800 million of public funds have been ineffectively allocated. The controversy centers on the £2.7 billion planned to be spent by spring 2030 through grants of up to £7,500 for households installing heat pumps or biomass boilers as part of the country’s net zero strategy.

Government analysis indicates that about 30% of these subsidized installations would have occurred without financial incentives, representing roughly £810 million in potentially avoidable spending. Critics argue this portion of funding disproportionately benefits wealthier homeowners who can already afford the significant upfront costs associated with heat pump installations. According to government data, an air source heat pump costs on average £13,431 to install, while a ground source system averages £26,841—approximately £9,000 more than replacing a conventional fossil fuel boiler.

Claire Coutinho, the shadow energy secretary, condemned the scheme for what she described as a misallocation of taxpayer money. She argued that subsidizing heat pumps for affluent households detracts from efforts to reduce energy bills across the broader population. Coutinho advocated for abandoning targeted taxes and subsidies in favor of policies focused on lowering electricity costs and restoring consumer choice in heating and transport.

The debate around the UK’s net zero commitments is intensifying ahead of the next general election. Reform UK has pledged to dismantle policies aimed at achieving the 2050 net zero target, including eliminating all renewable energy subsidies. This stance contrasts sharply with Energy Secretary Ed Miliband, who has reaffirmed the government’s commitment to net zero amid rising energy prices exacerbated by geopolitical tensions, including the war in Iran. Miliband, a former Labour leader and current contender in a potential Labour leadership contest, has expanded and increased funding for the Boiler Upgrade Scheme after its initial launch in 2022 under the previous Conservative government with a £450 million budget for three years.

A spokesperson for the Department for Energy Security and Net Zero defended the scheme, noting the growing public demand for heat pumps and emphasizing that the Boiler Upgrade Scheme has enabled many households to adopt this technology who would not have otherwise done so. The department also highlighted the Warm Homes Plan, which aims to provide heat pumps at no cost to low-income families, supporting the government’s goal to lift approximately one million households out of fuel poverty.
