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. The ACA is not a regulatory body, but provides an independent voice for and support to architectural practices that promotes and enables high standards in practice within the membership. The ACA maintains a directory of members and promotes the work of member architects in other ways, publishes a newsletter and arranges events and seminars all directed towards keeping members up-to-date with best practice. The ACA was founded in 1973 by former presidents of the RIBA. It has stood firm for quality in architecture and reliability of service in private practice ever since. Although its roots go back much earlier, the ACA was created at a time when there was no organisation in existence dedicated specifically to the interests of private practitioners.
