Builders for extensions, loft conversions, renovations and new builds. Builder Finder UK lists 9,800 builders in London, with the trades and services each one lists.
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.
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.
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.
