Scam Alerts: the Energy tricks doing the rounds
"Free" grants, callers who say they're from the government, and a "last chance" before a scheme closes. Here's how the tricks work, the red flags, and what a proper firm does instead. Updated whenever an official warning comes out.

How common are Energy scams?
Citizens Advice surveyed 2,112 UK adults and found that more than 19 million adults had been targeted by a "green" scam in the past year, and an estimated 5.2 million had fallen for one. Email, phone calls and texts were the most common approaches. 2021 survey
National Trading Standards, using data from nearly 10,000 call blockers in people's homes, found that scam calls offering Energy grants rose 85% in a single month (August to September 2022). The calls offered Solar panels, loft Insulation, spray foam, glazing and Boiler replacement. 2022 data
These are the most recent national figures of their kind that I could find at the source. They're a few years old, so I've dated them rather than dress them up as new. When a newer official figure is published, it goes here.
What's doing the rounds now?

ECO4 ends on 31 December 2026: expect "last chance" pressure
The government extended ECO4 by nine months, so it now ends on 31 December 2026. The Great British Insulation Scheme ended on 31 March 2026. A genuine closing date is a gift to a pressure seller. Ofgem's own guidance says installers are not approved by Ofgem, that you should ask any company that approaches you for its credentials, and that you should only agree to work once you've received a contract. You may be asked to pay towards the cost, and Ofgem says to shop around. checked 9 Oct 2026

Action Fraud is now "Report Fraud"
In England, Wales and Northern Ireland, Report Fraud has replaced Action Fraud. If anyone tells you to report to a different address, or asks for money to "recover" your losses, that's a second scam. The real details are below. checked 9 Oct 2026

"Green Energy cashback" cold calls
Callers claiming to be from a real Energy company have offered a "£1000 cheque as cashback" for buying "Green Energy", then asked for bank details. The real company had no such offer and doesn't make calls like this. Hang up, then ring the company on a number you find yourself. checked 9 Oct 2026
The red flags, and what a proper firm does instead
They came to you
An unexpected call, text, email or knock offering a "free" or "government" grant. Ofgem doesn't approve installers.
Today only
Pressure to decide now because the offer or the scheme is "about to close".
Bank details on the phone
Asking for your bank details, or saying they already have them and "just need to confirm".
"Fully funded"… but
The paperwork shows a contribution from you, or there's no written quote at all. Get it in writing before anyone starts.
A big deposit up front
For large jobs, pay in stages and avoid paying everything before the work is done.
Three quotes and a contract
A written quote and a written contract before any work. Get at least three quotes so you can judge what's fair.
You can check them yourself
A certification you can look up on the scheme's own website, such as TrustMark, the government-endorsed quality scheme.
You pay safely
A credit card gives you the most protection, then PayPal or a debit card.
Advice on quotes, contracts, payment and TrustMark: Citizens Advice. Cold-call warning signs: Action Fraud. Ofgem's lines: its ECO guidance for homeowners.
Been caught, or worried you might have been?
Scotland has its own reporting routes; Citizens Advice links to them from its scams pages.
Not sure if a quote or an offer is genuine? Ask me first.
Send me the quote, the letter or the leaflet. I'll read it as a person, not a computer, and tell you in plain English what's real, what's missing and what to ask. It's free.
