Check a conservatory and orangery builder before you pay

The short answer: the official registers are free and take minutes: TrustMark · [FMB]. Conservatories under 30m² are exempt from building regs — but the base, glazing and electrics are not. Membership is a vetting signal, not insurance — the written contract protects you more than any logo.

The pre-hire screen

1. Registers: TrustMark · [FMB]. 2. Companies House — company age, directors, prior dissolved firms (the full check). 3. Fixed quote against a written scope, staged payments, retention. 4. Ask what certification the work produces — and check it afterwards.
