Fake Window Replacement Grant Scam in the United Kingdom
In the UK, this scam exploits public awareness of real government-backed energy efficiency schemes, using their names to convince homeowners that free or subsidized window replacement is available.
Part of: Fake Window Replacement Grant Scam
Last reviewed: 5 July 2026
The United Kingdom's genuine energy efficiency support programs, which do fund insulation and some home upgrades for eligible households, give this scam a ready-made backdrop of legitimacy that fraudulent installers exploit by borrowing the language of real schemes without any actual government involvement.
How this scam works on the United Kingdom
Cold callers or door-to-door reps tell homeowners they qualify for 'free' double or triple glazing under a government energy scheme, often naming or vaguely referencing legitimate-sounding efficiency initiatives without ever producing an official scheme reference number. They typically claim eligibility is based on the homeowner's age, benefits status, or property type, mirroring the actual eligibility language used by real efficiency programs to sound credible.
Once the homeowner agrees to a home visit, the salesperson reveals that while 'the grant covers most of the cost,' a co-payment, survey fee, or installation charge is required upfront, which in reality represents the full retail price of the windows or more. Because the homeowner believes a real government subsidy is involved, they often skip the due diligence they would apply to an ordinary sales pitch, and any resulting contract typically has none of the protections or verifiable installer accreditation that genuine scheme-approved installers must carry.
Common red flags
- Caller references a government energy scheme but cannot provide a specific scheme reference or written documentation
- Claim that windows are 'free' but a co-payment or survey fee is required upfront
- No independent way offered to verify the company is an approved installer under any real scheme
- High-pressure door-to-door or cold-call tactics rather than a homeowner-initiated application
- Installer cannot produce accreditation or certification numbers that can be checked against an official register
- Requests for payment before any survey, paperwork, or grant confirmation has been provided in writing
How to protect yourself
- Contact your local council or the official energy efficiency scheme directly to verify eligibility and approved installers, rather than relying on the caller's claims
- Never agree to same-visit payment for a scheme you have not independently verified
- Ask for the installer's accreditation number and check it against the relevant official register
- Get the grant claim and payment terms in writing before making any decision
- Be especially cautious of unsolicited doorstep or cold-call offers, since genuine schemes rarely operate this way
- Consult Citizens Advice or a local trading standards office if unsure whether an offer is genuine
How to report it
- Report the company to Trading Standards via the Citizens Advice consumer service
- Report suspected fraud to Action Fraud, the UK's national fraud and cybercrime reporting centre
- Notify the relevant energy scheme administrator directly if a company falsely claimed affiliation
- Warn neighbors, especially elderly residents, who are frequently targeted by doorstep versions of this scam
Frequently asked questions
Are there real government-backed window or insulation grants in the UK?
Yes, genuine energy efficiency schemes do exist and can fund certain home upgrades for eligible households, but eligibility and approved installers should always be confirmed directly with the official scheme administrator or your local council, never taken on the word of a cold caller.
What should I do if I've already paid a deposit under a false grant claim?
Contact your bank or card provider to ask about reversing the payment, report the company to Action Fraud, and get advice from Citizens Advice on your consumer rights and cancellation options.
