Rogue Trader Scam

A rogue trader is a doorstep or online 'tradesperson' offering driveway, roofing, gardening or repair work at a tempting price. They press for a large cash deposit upfront, then carry out poor or unfinished work, 'discover' extra problems that were never there, and inflate the final bill. Older homeowners are often targeted. Taking time to get the offer in writing and to compare quotes can reveal the pressure tactics for what they are.

What this scam usually looks like

A rogue trader is a doorstep or online 'tradesperson' offering driveway, roofing, gardening or repair work at a tempting price. They press for a large cash deposit upfront, then carry out poor or unfinished work, 'discover' extra problems that were never there, and inflate the final bill. Older homeowners are often targeted.

Example message pattern

Example pattern — not a real report
Example pattern: "Hello, we're working on a driveway just down your road and have materials left over, so we can redo yours cheaply today only. We just need a cash deposit to start. Actually, once we lifted the surface we found the base is rotten, so it'll cost a lot more, but we must finish now."

This is a fictional, anonymised example used to illustrate the pattern. It is not a verified real message, and any names are used only to show how the scam typically reads.

Red flags to watch for

  • The work is offered unsolicited at your door or via an unprompted message, often claiming leftover materials or a 'today only' price.
  • You are pressured to decide immediately and to pay a large deposit in cash before any work is done.
  • Extra, expensive problems are 'found' once work begins, with no clear evidence they existed.
  • The trader has no written quote, no proper contract, and a vague or untraceable business address.
  • You are discouraged from getting other quotes or from involving family before agreeing.

What to do

  • Never agree to doorstep work on the spot; take time and tell the trader you will be in touch.
  • Get a clear written quote and compare it with at least two other traders you have approached yourself.
  • Check the business properly, including a verifiable address, reviews and any recognised trade scheme membership.
  • Where possible, pay by a traceable method in stages tied to completed, inspected work rather than a large upfront cash sum.

If you already clicked or replied

  • If you have paid a deposit and the trader has vanished or the work is poor, stop further payments immediately.
  • Report the matter to your local trading-standards or consumer-protection service with all details you have.
  • Tell your bank or card provider if you paid that way, as some payments may be disputable.
  • Keep all paperwork, photos of the work, receipts and any messages in case they are needed for a report or claim.

What not to do

  • Do not pay large cash deposits to an unsolicited doorstep trader.
  • Do not let yourself be rushed into agreeing before you have compared quotes.
  • Do not allow more work or payments once you suspect the extra 'problems' are invented.

Fake Supplier Scam

A fake wholesale or B2B supplier advertises bulk goods at prices that beat the market, then asks for payment by bank transfer. Some vanish after the first order, while others build trust with small, genuine deliveries before disappearing on a large one. Because bank transfers offer little recourse, recovering the money is often very difficult.
High risk Rental

Fake Letting Agent Scam

A fake letting agent or 'property manager' posts convincing rental adverts, sometimes copied from real listings, then collects holding deposits, referencing fees or a first month's rent from several hopeful applicants at once. Once the money is in, the agent disappears and the property is never let. Verifying the agent is genuine and refusing to pay before viewing the property and seeing proper contracts are the strongest protections.
High risk Bank & Payment

Overpayment Scam

A buyer, employer, or 'client' sends you a payment or cheque for more than they owe, then asks you to send the extra back. The original payment is fake or is later reversed, leaving you out of pocket for the refund you sent.

Frequently asked questions

Are all doorstep traders rogue traders?
No, but unsolicited doorstep offers carry higher risk. Genuine traders will usually give you time, a written quote and references. Pressure to pay cash immediately is a pattern commonly linked to scams.
Why do rogue traders prefer cash deposits?
Cash is hard to trace and difficult to recover. By taking a large cash sum upfront, a rogue trader can disappear or inflate the bill knowing you have little leverage to get your money back.
What if a trader 'finds' extra problems after starting?
Be cautious. Newly discovered, costly faults that must be fixed 'right now' are a known tactic. Ask for evidence, pause the work, and consider getting an independent opinion before paying anything more.
How can I protect an older relative from this?
Encourage them never to agree to doorstep work alone, to call you before paying, and to use traders found through trusted recommendations. A simple 'no decisions on the doorstep' rule can help a lot.
