British Institute of Interior Design (BIID)

The British Institute of Interior Design encourages and supports creativity and competence in the field of interior design through facilitating best practice, practical professional support, development opportunities and education.

The organisation was founded in 1966 as the Interior Decorators and Designers Association (IDDA). In 2001, the IDDA was amalgamated with the globally recognised International Interior Design Association UK Chapter (IIDA), to form the British Interior Design Association (BIDA). The Secretary of State recognised the BIDA as the pre-eminent body in the field in 2009 and granted Institute status so it became the British Institute of Interior Design.

It sits on the Council of the Construction Industry Council, CIC, and has published the standard Forms of Agreement for interior designers in collaboration with RIBA.

The BIID Interior Design Job Book is now the textbook for professional practice for interior designers, again published by RIBA.

The BIID has launched its professional pathway to becoming a registered interior designer, following graduation and experience.

BIID is a Member of IFI, the International Federation of Interior Architects & Designers.
