The Rochford Council warning landed in my inbox this morning: residents are being cold-called by people offering ‘energy support scheme’ upgrades. The pitch is familiar, free boiler, new insulation, solar panels at no cost. The catch is that nothing is free. Victims hand over bank details or sign credit agreements they cannot cancel.
As reported by Rochford Council, these fraudsters are exploiting the government’s ECO4 scheme, the £4 billion energy company obligation that runs until March 2026. Households on benefits or low incomes qualify for fully funded home improvements. Scammers know this and are now weaponising the scheme’s legitimacy.
How the scam works, and who it targets
The fraud typically begins with a phone call or a door knock. The caller claims to be from ‘the government energy scheme’ or ‘ECO4 approved’. They offer a free heat pump or loft insulation. Then they ask for a bank account number to ‘process the grant’ or demand a £200 deposit for a survey that never happens.
Ofgem figures show energy-related fraud complaints rose 40% in 2024. The National Cyber Security Centre recorded 1,200 reports of fake energy rebate texts in December alone. The victims are disproportionately older homeowners, people in fuel poverty, and households who have seen energy bills rise by 74% since 2021.
What this misses is that genuine ECO4 grants require no upfront payment. The scheme is funded by energy suppliers, not homeowners. If someone asks for money before installation, it is a scam. Full stop.
Who qualifies, and who doesn’t
ECO4 eligibility is strict. You must own your home (private tenants are excluded) and receive one of the following: Pension Credit, Income Support, Universal Credit, Child Tax Credit, Working Tax Credit, or Housing Benefit. The property must also have an EPC rating of D, E, F, or G, meaning it leaks heat.
But the rules are not widely understood. A 2023 survey by Energy Saving Trust found 62% of low-income households did not know they might qualify for free insulation. Scammers exploit this knowledge gap. They tell a pensioner on Pension Credit that a full heat pump system is theirs for a £500 ‘admin fee’. The fee disappears. The heat pump never arrives.
The catch is that even genuine ECO4 installations can be slow. Some suppliers have waiting lists of six months or more. Desperation makes people vulnerable. If a scammer promises installation next week, that is a red flag.
How to verify a genuine installer
Three checks will stop almost every ECO4 fraud. First, the installer must be registered with TrustMark, the government-endorsed quality scheme for home improvements. Second, they must hold MCS certification for any renewable technology (heat pumps, solar panels). Third, the work must be arranged through your energy supplier or a local authority scheme. You can call your supplier directly to ask if they have approved a contractor for your area.
Energy Saving Trust runs a free advice line (0800 444 202) that can confirm whether an offer is legitimate. Citizens Advice also has a dedicated scam reporting tool on its website. If you suspect fraud, report it to Action Fraud on 0300 123 2040.
Rochford Council is right to issue this alert. But the problem is national. Every council in England should be sending similar warnings. The government could help by publishing a single, searchable register of all ECO4-accredited installers, something that does not yet exist in a consumer-friendly format.
What to do if you are approached
Do not sign anything on the doorstep. Do not hand over bank details. Ask for the installer’s TrustMark number and MCS certificate. Then call TrustMark on 0333 555 1234 to verify. If the caller cannot provide these numbers, end the conversation.
Households on low incomes should still apply for ECO4 through their energy supplier or the Energy Saving Trust website. The scheme runs until 31 March 2026. Applications are free. Installation is free. Anyone who tells you otherwise is lying.
Frequently Asked Questions
In the UK, genuine ECO4 grants never require upfront payment. If someone asks for a deposit, admin fee, or your bank details to 'process the grant', it is a scam. Always verify the installer is registered with TrustMark and MCS certified, and contact your energy supplier directly to confirm they have approved the contractor.

Your property must also have an EPC rating of D, E, F, or G. The scheme runs until March 2026 and is funded by energy suppliers, so no money comes from homeowners.
If you have handed over bank details or signed a credit agreement, contact your bank immediately to freeze your accounts and report the fraud to Action Fraud on 0300 123 2040. You can also call the Energy Saving Trust's free advice line on 0800 444 202 for guidance on next steps.
No, genuine ECO4 installations are fully funded by energy suppliers under the £4 billion government scheme. There should be zero upfront costs, deposits, or admin fees. Some suppliers may have waiting lists of six months or more, but if a scammer promises installation within a week, it is a major red flag.
