Checking a construction company in Cardiff

  1. Check that the company number on the quote matches Companies House and that the company is active, not dissolved or in liquidation.
  2. Never pay a large deposit up front. Pay in stages, against work you can see.
  3. Ask for proof of public liability insurance and check the policy with the insurer, not via the builder.
  4. Check who the directors are and how long the company has existed: a firm set up a few months ago with a big project is a warning sign.
  5. If bank details change by email, call the company on a number you look up yourself before paying.
