Notes to editors

About ARB 

The Architects Registration Board (ARB) is an independent professional regulator, established by Parliament as a statutory body, through the Architects Act, in 1997. It is accountable to government. The law gives ARB a number of core functions: 

• To ensure only those who are suitably competent are allowed to practise as architects. We do this by approving the architecture qualifications required to join the Register of Architects. 

• To maintain a publicly available Register of Architects so anyone using the services of an architect can be confident that they are suitably qualified and are fit to practise. 

• To set the standards of conduct and practice the profession must meet and take action when any architect falls below the required standards of conduct or competence. 

• To set requirements for and monitor the continuous professional development that architects must undertake, to provide assurance to the public about the continuing competence of the profession. 

• To protect the legally restricted title ‘architect’. 

The Board 

The ARB Board is made up of 11 members, all appointed by the Privy Council. This includes one independent, non-executive Chair and ten non-executive Board members made up of five members of the public and five architects. Board members are responsible for maintaining and promoting the public’s trust and confidence in the integrity of both ARB and of the architects’ profession.
