According to the latest figures for the Boiler Upgrade Scheme, 2,000 heat pump installations were given a subsidy of £5,000 in July, costing the taxpayer £10 million.

In response, not-for-profit trade body the Energy and Utilities Alliance (EUA) has stated the subsidy would be more effective if targeted towards energy efficiency measures in the home, reducing bills for Brits reportedly already in debt on average £206 to profiting energy companies.

Data from the Energy Savings Trust indicates £10 million would provide 19,000 lofts with insulation, saving households £4.8 million a year on bills, while reducing carbon emissions by 11,400 tonnes. If used to fit cavity wall insulation, 8,400 homes would benefit, saving £2.4 million a year on bills and reducing carbon emissions by 5,600 tonnes.

Fitting a heat pump to 2,000 homes reduces carbon by 3,200 tonnes but total household bills will increase by £186,000 a year.

Chief Executive of the Energy and Utilities Alliance, Mike Foster said: “We are in the middle of a cost of living crisis; bills are soaring and consumers hurting. Is now the time for taxpayers to pay to fit a heat pump, when there are better ways of reducing bills for more people and cutting greater levels of carbon?”

“The former Chancellor, Rishi Sunak, has spotted the problem and called for this unfair subsidy to be scrapped. Will the bookies favourite to be the next PM, Liz Truss, do the same?”

“When times are tough, there is even greater importance on government providing the best use of hard-earned taxpayers’ cash. It simply isn’t the time to give £5,000 cash handouts to those who can afford their energy bills, compared to helping the millions in dire need of support.”

“The total scheme, over three years, amounts to £450 million subsidising 90,000 heat pumps. That same amount means nearly one million homes could get free insulation, cutting bills by nearly £220 million a year. Surely that’s the greater prize in these difficult times?”
