BEIS has worked with NBS to map the ETL product categories within the 56 technologies against the UNICLASS 2015 codes.

UNICLASS 2015 is a classification structure used to identify and manage aspects such as information, components, products and services throughout the lifecycle of a building asset. UNICLASS 2015 is managed and delivered by NBS and the use of the classification structure is a requirement for BIM Projects, as set out by the BS EN ISO 19650 series of standards.
