Founded in 1965 as the Interior Decorators and Designers Association, it merged in 2002 with the UK chapter of the
International Interior Design Association becoming the British Interior Design Association. In 2009, the
Secretary of State awarded it
Institute status, and it became the British Institute of Interior Design. It remains the only professional membership organisation for the interior design industry in the UK to hold institute status. In 2013, it subsumed the
Interior Design Association, a business association representing interior designers working in the commercial sector. ==Conduct==
