Is it safe to pay a contractor, tradesperson, or builder in full before the work is done?
Full upfront payment to a contractor you have not worked with before is strongly inadvisable. A small deposit to cover materials is common practice, but full payment before completion creates significant risk of non-performance or disappearance.

Explanation
Contractor and tradesperson fraud — where payment is taken and the work is never started or completed — is a persistent consumer problem. The pattern typically involves door-to-door solicitation or online listing, a competitive quote, a request for a significant upfront payment, and then substandard work, abandoned work, or a complete disappearance.
Larger projects reasonably involve staged payments tied to milestones: a deposit before start, payment on completion of specific stages, final payment on satisfactory completion. This structure protects both parties and is standard practice in the construction and trades industry.
Verify contractors independently before any payment: check membership of relevant trade bodies, ask for and contact references, search the company name online, verify their business registration, and confirm they hold appropriate insurance. Reputable tradespeople welcome these checks.
Never pay in cash for large jobs — cash payments leave no record and complicate any dispute. Bank transfer or cheque creates an audit trail. Use a credit card for any portion you can — credit card payments offer chargeback rights if the work is not delivered.
Common red flags
- Contractor requests full payment before any work begins
- Contractor can only be contacted by phone or cash and has no verifiable business address
- They are not a member of any relevant trade body or accreditation scheme
- They cannot provide references from previous clients
- They will only accept cash
- Quote was given very quickly without a detailed assessment and is significantly below all other quotes
What to do now
- Agree staged payment milestones in a written contract before work begins
- Verify trade body membership and business registration independently
- Request and contact at least two references
- If you have already paid and work is abandoned, send a formal demand letter, then small claims court if needed
- Report rogue traders to your national consumer protection or trading standards authority
- Use credit card for any portion possible to retain chargeback rights
Frequently asked questions
Is a deposit before work starts normal?
A deposit of 10-30% is common practice to cover initial material costs and demonstrate commitment from both sides. Full payment before any work starts is not standard and should be resisted.
The contractor wants cash only — should I be concerned?
Yes. Cash-only requests eliminate the paper trail that protects you in a dispute. Reputable businesses accept bank transfer at minimum. A cash-only insistence, particularly combined with a below-market price, is a significant warning sign.
