How to choose between them

  • 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.

Builders in London: common questions

Should I use a JCT contract for domestic work?

For anything over about £10,000, yes. The JCT Home Owner contract is short, plain English and free to buy. It fixes the payment schedule and the process if things go wrong, which is exactly what an informal arrangement does not.

How much deposit should a builder ask for?

Materials up front is reasonable. A large percentage of the total is not. Stage payments against completed work are the norm, and a firm insisting on 50% before starting is a warning sign.
