Red flags and doorstep scams
One red flag does not always mean someone is dishonest. Several together are a reason to slow down and do more checks.
Information, not legal advice. This guide explains official rules in plain words for England, with links to the sources. Rules change and every job is different, so check the source or get advice for your situation. Last checked 24 October 2026.
Common warning signs
- Cash only, or everything upfront. Citizens Advice says to avoid traders who do this (Citizens Advice).
- Only a mobile number, and no address (Citizens Advice).
- Pressure to decide or pay quickly. Being asked to transfer money quickly is a sign of a scam (Citizens Advice).
- Nothing in writing. Not getting written confirmation of what was agreed is another sign (Citizens Advice).
- Unusual ways to pay, such as vouchers or money transfer services (Citizens Advice).
- A price that seems too good to be true (Citizens Advice).
- Scheme logos you cannot verify on the scheme's own website (FMB).
- "No need for permission or paperwork" for work that may need it. See permissions.
Doorstep callers
Be careful with anyone who knocks to say they have spotted a problem with your roof or drive and can fix it today. You do not have to decide on the doorstep. Take their details, close the door, and check.
If you do agree a contract at home, the law usually gives you 14 days to cancel. The trader must give you information about this right (Citizens Advice; CCR reg. 30). For most off-premises contracts, failing to give notice of the right to cancel is a criminal offence (CCR reg. 19). See cancelling building work.
Where to report
- Unsafe or dishonest traders: contact the Citizens Advice consumer service, which passes reports to Trading Standards. You usually cannot report to Trading Standards directly (Citizens Advice).
- Fraud or scams in England, Wales and Northern Ireland: Report Fraud. If money has gone, contact your bank first.
- If you are in danger or a crime is happening now, call 999.
Common questions
What should I do if a builder knocks on my door offering work?
You do not have to decide there and then. Take their details, check them, and get other quotes. If you agree a contract at home, you usually have 14 days to cancel.
Who do I report a rogue trader to?
Contact the Citizens Advice consumer service, which refers cases to Trading Standards. Report fraud to Report Fraud and tell your bank if you have paid.
