United Kingdom

Current Implementation Status

United Kingdom has formally transitioned from the UK National Standardised terminology and definitions for texture modified foods and thickened liquids to IDDSI. IDDSI has been implemented in United Kingdom since April 2019.  Many thanks to the UK IDDSI Steering Committee for guiding a successful IDDSI implementation, co-chaired by Joanna Instone of the BDA and Liz Boaden of the RCSLT.  IDDSI is supported by the Royal College of Speech and Language Therapists, British Dietetics Association, National Association of Care Catering.

Reference Group

An IDDSI reference group is currently being assembled to monitor and foster IDDSI implementation.  If you are interested in contacting the UKIRG, please contact us.
