## Before you hire an architect
_What to check when choosing this kind of trade (general guidance, not a claim about this business):_
- 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.
