Four Arrested in UK Green Energy Fraud Probe

Four people were arrested on Wednesday in the United Kingdom on suspicion of conspiracy to defraud, after an investigation into alleged fraudulent claims linked to the government’s Energy Company Obligation 4 (ECO4) home insulation scheme. Officials said the suspected claims totalled £44 million.

The Serious Fraud Office (SFO) said it carried out raids across three counties as part of the inquiry. During the searches, investigators seized computers, hard drives, and crypto assets, officials said.

According to the SFO, the investigation centres on allegations that three companies—JJ Crump, South Coast Insulation Services, and Warmfront—claimed public funds for insulation work that was not carried out. Officials alleged the claims related to insulation activity on around 5,000 properties where no installations took place.

South Coast Insulation Services entered administration in February, according to the information provided. The SFO described the suspected activity as a “sophisticated and systemic fraud” that exploited a scheme intended to reduce fuel poverty.

ECO4 was launched in 2022 and has since closed. The programme aimed to install energy-efficiency measures in more than 300,000 homes, with a focus on vulnerable households. The total cost was £4 billion, funded through household energy bills.

The scheme has also faced wider scrutiny over the quality of some insulation work, separate from the fraud allegations. Reports have linked poor installation outcomes to problems including damp and mould in numerous homes.

A National Audit Office report said 98% of external wall insulations under the scheme required repairs. In response, the government launched a “find-and-fix” programme, and officials said more than 3,000 of 30,000 affected homes have already been repaired.

For markets and policy stakeholders, the case places attention on how large, bill-funded energy-efficiency programmes are administered and monitored. Key unknowns include the identities of those arrested, whether charges will follow, and how much of the alleged £44 million in claims can be recovered, as the investigation continues.
