Does an architect have to be RIBA registered?

An architect doesn’t have to be registered with the RIBA (Royal Institute of British Architects) in order to practise here in the UK. However, in order to legally practise as an architect in the UK, they must be registered with the Architects Registration Board (ARB). The ARB is the regulatory body for architects in the UK and is responsible for maintaining the Register of Architects.
The title ‘architect’ is protected by law in the UK. It can only be used by someone who is on the Architects Register. Only ‘architect’ is protected in this way, the protection doesn’t apply to terms like ‘architectural consultant’ or ‘architecture practice’. When looking for an architect, check to see if they use the word ‘architect’ or ‘architecture practice’ as this can be an indicator that they may or may not be registered.
While RIBA membership is not actually a legal requirement for practicing architecture, the organization does provide support and guidance to its members. RIBA membership is voluntary, and architects who are not RIBA members may still be highly qualified and experienced.
That being said, becoming a member of the RIBA indicates that an architect has met certain standards of education and professional development and has agreed to abide by the RIBA Code of Professional Conduct. This can often help to give you more confidence in the architect’s skills and professional standards, especially if you are looking for RIBA registered architects.
We know it’s a big commitment starting a project. When hiring an architect, the first thing to ascertain is whether they are registered with the ARB and are allowed to legally practice architecture in the UK. It can then be up to you if you feel you need the added reassurance of an architect being an RIBA member.
