The Energy Company Obligation scheme is meant to cut bills for low-income households. Instead, it has become the target of a £44m fraud investigation that led to four arrests this week. The scale is staggering: the amount allegedly stolen could have upgraded 1,400 homes to an EPC band C.
As reported by MSN, the probe involves suspected fraudulent claims for insulation and heating installations that never took place or were substandard. The arrests come as Ofgem tightens its oversight of the scheme, which has already distributed hundreds of millions in taxpayer-funded energy savings.
Who qualifies, and who doesn’t
ECO4 targets low-income households in poorly insulated homes. To qualify, you must receive certain benefits or be referred by a local authority. The scheme covers cavity wall insulation, loft insulation, boiler upgrades, and heat pumps. But the fraud has made some installers nervous. Several legitimate firms told Axiom they are now waiting weeks for Ofgem to validate claims, delaying installations for genuine applicants. The Energy Saving Trust estimates that a typical 3-bed semi could save £300–£600 a year on heating bills after a full ECO4 upgrade, but only if the work is done properly.
What it costs a typical 3-bed semi, and who pays
For the homeowner, ECO4 grants are free. The cost is borne by energy suppliers through the Energy Company Obligation, which adds about £30 a year to every household’s bill. That means the £44m fraud effectively took money from every billpayer. Ofgem confirmed to the BBC last month that it has suspended payments to several suppliers pending audits. The scheme’s complexity, involving multiple suppliers, installers, and local authorities, creates loopholes that criminals exploit. A 2023 National Audit Office report warned that ECO fraud could reach £100m by 2025.
How to protect yourself, and your grant
But the arrests do not mean the scheme is broken. Thousands of legitimate installations happen every month. The key is due diligence. Check that your installer is registered with TrustMark and holds PAS 2030 certification for the specific work. Ask for references from previous customers. Never pay upfront: ECO4 grants are paid directly to the installer by the energy supplier. If an installer asks for cash or a bank transfer, walk away. The government’s Simple Energy Advice service can verify your eligibility and recommend vetted installers in your area.
What happens next
Ofgem has pledged to accelerate its review of ECO4 claims and increase unannounced site inspections. The four arrested individuals have been bailed pending further investigation. For homeowners, the immediate impact is likely to be longer waiting times for grant approval as checks tighten. But the alternative, a scheme so porous that fraudsters can steal £44m, is untenable. The honest majority will benefit from a cleaner system in the long run. If you are considering an ECO4 application, start the process now but expect delays. And always verify your installer before any work begins.
