How do I spot a fake utility bill or energy scam email?
Fake energy and utility emails threaten supply disconnection unless you pay immediately through a link — real suppliers send paper bills and never cut supply without proper written notice.
Last reviewed: 10 June 2026
Explanation
Energy and utility impersonation scams peak during periods of price volatility or following government subsidy announcements. Fraudsters send emails or texts purportedly from electricity, gas, or water suppliers claiming you have an overdue balance and your supply will be cut within hours unless you pay online immediately through the provided link.
Legitimate utility suppliers follow a regulated disconnection process that involves multiple paper letters over weeks, not an immediate cut following a single email. In the UK, energy suppliers must follow Ofgem rules; in the US they are regulated by state commissions. Any claim that your electricity will be cut in 24 hours because of an email you just received does not reflect how utilities actually operate.
A second variant exploits government energy rebate schemes. When subsidies are announced, fraudsters impersonate the energy company or even a government body and email you to 'apply' for a rebate, harvesting your bank details in the process. Legitimate rebates are applied to your account automatically or processed through channels your supplier confirms independently.
Verify any overdue balance claim by logging in to your supplier's account portal through a bookmarked address, or by calling the number on a paper bill you have received in the post.
Common red flags
- Threat of supply disconnection within hours via an email
- Link in the email goes to a domain that is not your supplier's exact official site
- Offer of a government energy rebate that requires your bank details
- Sender address is not the official supplier domain
- You have no overdue balance visible in your online account
- Request to pay by bank transfer rather than through the account portal
What to do now
- Log in to your supplier account directly through a bookmark or typed address
- Call the supplier's official customer service number from a paper bill
- Do not click the payment link in the suspicious email
- Report energy scam emails to the National Cyber Security Centre (UK) or FTC (US)
- If you paid, contact your bank immediately to dispute the transaction
Frequently asked questions
Do real energy suppliers ever email me about overdue bills?
Yes, but they always direct you to log in to your account portal — they do not provide a one-click payment link in the email. Verify the balance in your portal before paying anything.
How do I claim a legitimate government energy discount?
In the UK, legitimate schemes like the Warm Home Discount are applied through your supplier directly — you do not need to enter bank details to claim them. Check gov.uk for official scheme details.
What if I pay the wrong amount to a fake account?
Report to your bank immediately. Faster payments can sometimes be recalled within 24 hours. Also report to Action Fraud (UK) or the FTC (US).
