Investigation into UK Government Energy Efficiency Scheme Fraud

Arrests and Searches Conducted by Serious Fraud Office

April 22 (Reuters) - Four people have been arrested in Britain and six addresses searched over an alleged 44 million pound-plus ($60 million) fraud involving a government energy efficiency scheme designed to tackle fuel poverty, the Serious Fraud Office said on Wednesday.

Public Appeal and Companies Under Scrutiny

The SFO also launched a public appeal for information about three companies, called Warmfront, JJ Crump and South Coast Insulation Services, which are alleged to have submitted claims with little or no work done between 2022 and 2024.

Statement from SFO Interim Director

"This scheme was designed to reduce carbon emissions, help households cut costs and stay warm – instead in many cases we suspect little or no work was done," said Graham McNulty, the SFO interim director, urging people such as installers to speak up.

"Our door is open and coming forward is the right thing to do," he said.

Status of Companies Involved

Warmfront

Warmfront, based in Cannock, central England, was sold in 2024 and now trades under new management not connected to this investigation, the SFO said.

South Coast Insulation Services

South Coast Insulation is permanently closed, its website shows.

JJ Crump

Sheffield-based JJ Crump did not immediately respond to a request for comment.

Key Takeaways

  • The probe targets misuse of the ECO/GBIS energy efficiency scheme, which has faced broader scrutiny over poor-quality installations and suspected fraud (en.wikipedia.org).
  • Ofgem has identified around £6.7 million in rejected claims and estimated fraud at 1.75 % of the scheme’s value, though watchdogs warn actual fraud could be significantly higher (publications.parliament.uk).
  • The energy scheme has been widely criticized for systemic failures, including the suspension of many installers and thousands of homes afflicted by defective work, prompting recommendations for SFO intervention (publications.parliament.uk)
