  • Check the registration yourself. Trade body memberships are public, and each body's own register confirms them in a minute.
  • Get three quotes on the same specification. Written down, split into labour, materials and anything structural. Most people compare a total against a total and end up choosing between two different jobs.
  • Ask what is not included. Making good, waste removal, scaffolding and VAT are the four that turn a cheap quote into an average one.
  • Never pay a large deposit up front. Materials in advance is normal. Half the total before anyone turns up is not.
