Association Of Consultant Architects

The Association of Consultant Architects (ACA) is the national professional body representing architects in private practice - consultant architects - in the UK. Membership is open to Registered Architects practicing on their own account either alone or in partnership or as a Director of a company whose business consists wholly or mainly of an Architects' practice or an allied field.

An architect who elects to become a member of the ACA will be required to pay a subscription based on the number of personnel working within his or her practice. Any other principals of the practice, whether working in partnership or in other forms of collaboration, will then become eligible for full voting membership.

Voting members must be Registered Architects, but do not have to be members of the RIBA. They may adopt the suffix ‘ACArch'. The title "architect" is protected and regulated by the Architects Registration Board (ARB).
