How to avoid rogue traders

Rogue traders usually win before the work starts. They create urgency, avoid written detail, and persuade the homeowner to pay before the risk is understood.

You cannot remove every risk from building work, but you can make it much harder for a bad trader to control the situation.

Slow the decision down

Pressure is a major warning sign. Be careful with anyone who says the price is only available today, knocks on the door uninvited, or pushes for immediate payment.

Citizens Advice recommends checking traders before hiring and suggests starting with local council resources where available: Find a trader and check you can trust them.

Check the basics

Before you agree to work, check:

• business name and trading address
• Companies House record if they claim to be a limited company
• public reviews across more than one site
• insurance cover
• trade memberships where relevant
• previous work you can actually verify
• waste carrier details for jobs involving disposal

No single check proves someone is safe. The point is to look for consistency.

Get a written quote

Do not rely on a verbal quote for meaningful work. A written quote should describe what is included, what is excluded, the price, and when payments are due.

If the trader avoids writing things down, that is a risk in itself. Written terms protect good traders too because they reduce scope disputes and payment arguments.

Avoid vague upfront payments

Rogue traders often ask for money before there is a clear job structure. They might call it a deposit, materials money, or a booking fee.

The safer approach is to connect every payment to a real reason:

• named materials
• confirmed order dates
• completed preparation
• visible project stages
• final completion checks

Red flags before you hire

Pause if the trader:

• will not provide a written quote
• refuses to discuss payment stages
• asks for cash without a receipt
• changes bank details suddenly
• cannot explain who is doing the work
• gives no clear address
• says building control or permissions are not your concern

One red flag might have an explanation. Several together should make you walk away.

FAQ

Are online reviews enough?

No. Reviews help, but they should be one signal among many. Check identity, insurance, written terms, and payment structure too.

Should I hire someone who knocks on the door?

Be very cautious. Do not agree or pay on the doorstep. Take time to check the trader independently.

What should I do if I suspect a rogue trader?

Stop paying, collect the evidence, contact Citizens Advice for consumer guidance, and report urgent threats or fraud concerns to the relevant authorities.
