"Architect" is a title protected by law - only people on the official Architects Register (held by ARB) may use it. Confirm they're on it before you commission a design.
Check the Architects RegisterSmart checks
Before you hire an architect
Only someone on the Architects Registration Board (ARB) register may legally call themselves an 'architect' in the UK — ask for their ARB number and check it free at arb.org.uk. An 'architectural designer' or 'technologist' is a different, unregistered role (often capable, but not the same protection).
Agree how they charge before any work starts — a percentage of the build cost, a fixed fee, or an hourly rate — and exactly which stages it covers (concept design, planning application, building-regulations drawings, work on site), so there are no surprises later.
Confirm what they will actually handle versus what is excluded — the planning application, the building-control drawings, and whether they will administer the builder's contract on site — and get it, and a portfolio of similar projects, in writing.
Ask to see a portfolio of completed work like yours, plus recent references you can contact.
Check the credentials and registrations that matter for this work — and that they are current.
