Ask Baily instead of Checkatrade
Checkatrade publishes a directory — you still have to call 3–5 contractors, chase quotes, and vet licensing yourself. AskBaily scopes your Marylebone project with AI, then routes you to one builder who has already cleared Westminster City Council permit + overlay checks for the georgian townhouse and red-brick mansion block your home likely is.
