A senior Labour donor has questioned claims that heat pumps reduce household energy bills, warning that the technology is often oversold to consumers. Dale Vince, founder of the renewable energy company Ecotricity, said heat pumps rarely save money and typically require a well-insulated property merely to break even.

Heat pumps form a central pillar of Energy Secretary Ed Miliband’s £15bn Warm Homes Plan, which aims to upgrade five million low-income households with measures such as heat pumps, insulation and solar panels. Speaking on BBC Politics Live, Mr Vince said his two decades of experience using heat pumps led him to challenge the “general narrative” that they lower costs, arguing that most UK installations operate below the efficiency level needed to deliver savings.
Mr Vince stated that a heat pump requires a coefficient of performance of at least four to be cost-effective, while the UK average is closer to 2.8. He claimed this results in household energy bills rising by around 30 per cent, describing the promotion of heat pumps as a form of “mis-selling”. Independent analysis by the Energy Saving Trust has similarly found that households with newer gas boilers may see little or no financial benefit from switching.

The Department for Energy Security and Net Zero disputes this assessment, saying heat pumps can save households up to £130 a year and more when combined with solar panels and battery storage. While installations have increased modestly, they remain below previous targets, prompting the government to lower annual goals as it continues to promote the technology as part of its wider decarbonisation strategy.
