The Warning Signs

Before You Hire

1. No fixed address Just a mobile number. No office, no yard, no traceable address.

2. No written quote "I'll work it out as we go" — recipe for disaster.

3. Cash only "I'll do it cheaper for cash" often means no records, no comeback.

4. Unusually cheap 30%+ below other quotes? They're either lying or cutting corners.

5. Pressure to decide now "This price is only valid today" — legitimate builders don't do this.

6. Large deposit demanded More than 10-15% upfront is a red flag.

7. Can't show previous work No photos, no references, no sites to visit.

During the Job

8. Materials not as specified Substituting cheaper alternatives without agreement.

9. Workers keep changing Different people every day = subcontracted chaos.

10. Avoiding building control "You don't need that" when you clearly do.

11. More money before milestones Asking for payment before agreed stages complete.

12. Disappearing for days "Waiting for materials" repeatedly = juggling jobs.

Always:

Written contract.
Check Companies House.

Pay in stages, not upfront.

Pay large deposits.
Pay cash without receipt.
Let them skip building control.
Ignore your instincts.

If You've Been Caught

Document everything.
Report to Trading Standards.
Consider small claims court.
Check if any trade body covers them.
