What to check before you hire

Getting started

  1. Describe the job. What needs doing, where, and when you'd like it done.
  2. Shortlist two or three. Look at the trades and services each business lists and where it is based.
  3. Compare quotes. Ask each of them for a written quote for the same job, so the prices can be compared.
  4. Agree in writing. Confirm the price, start date and payment schedule before work begins.

Frequently asked questions

How do I choose between builders in London?

Compare two or three. Look at the kind of work each one lists, ask for references and photos of similar jobs, and get a written, itemised quote before you agree to anything.

How much does a builder cost?

It depends on the size of the job, materials, access, and how soon you need it done. Most trades quote a fixed price for a defined job and a day or hourly rate for small repairs. Asking two or three local businesses for a written quote is the quickest way to see the going rate in London.

Does Builder Finder UK check the businesses it lists?

No. Builder Finder UK is a directory: a listing is not a recommendation, and we do not check qualifications, registrations or insurance. Ask each business for evidence of whatever the job needs before work starts.
