Worth checking yourself
Their public evidence comes from a single source. Look them up on another site before deciding.
No credentials are shown here and the business has not claimed this profile. Ask to see certificates and insurance directly.
Verify at the sourceCheck them yourself
"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 RegisterOnly 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.
