Frequently Asked Questions

How many quotes should I get for my project?

We recommend getting at least 3 quotes from different contractors. This gives you price comparison, different approaches, and confidence in market rates. For major projects over £10,000, consider getting 4-5 quotes.

What if a contractor asks for payment upfront?

Legitimate contractors rarely require more than 10-20% deposit. Be very wary of contractors demanding full payment or large sums upfront. This is a major red flag for cowboy builders.

How can I verify a contractor's insurance?

Ask for current insurance certificates and contact the insurance provider directly to confirm coverage. Don't rely on certificates alone as these can be forged.

What should I do if work is substandard?

Document issues with photos, communicate concerns in writing to the contractor, allow reasonable time for remedial work, then escalate through trade body complaints procedures or legal channels if necessary.

Are online contractor platforms reliable?

Reputable platforms like Trustmark, Checkatrade, and established trade body directories provide good initial vetting. However, you should still conduct your own verification checks.

Can I cancel a contract after signing?

You have 14-day cooling-off rights for contracts agreed away from business premises, and 7 days for certain types of contracts over £42. Check your specific contract terms.
