The British Institute of Interior Design strongly recommends that designers use the RIBA Domestic Professional Services Contract 2020: Interior Design Services or the RIBA Concise Professional Services Contract 2020: Interior Design Services instead of the BIID Agreement for Interior Design Services: ID/10: 2010. The new contracts are available to personalise and download as PDFs via the RIBA Contracts Digital online tool and as paper copies. These are lised in the RIBA Contracts section.
