This is the third of our quarterly updates for Uniclass in 2026. It includes improvements across four tables, a result of external input from users, internal development roadmaps and mapping of Uniclass to NRM3.
NBS is in the process of completing a comprehensive mapping between NRM3 and Uniclass, creating a direct relationship between lifecycle cost planning and asset classification. The work includes new and updated Uniclass codes, a fully verified mapping, and a robust methodology that strengthens Uniclass as a foundational framework for future industry standards development. As part of this, 24 new codes have been created across the Products, Systems and Activities tables to date.
Following a query from Transport for Greater Manchester, new classifications have been added under ‘Pr_82 Vehicle products’, including a new sub-group for ‘Road-based vehicles’. This is to enable the classification of non-motorized vehicles like pedal cycles as well as the addition of further codes in this part of the product table.
Smoke dampers’ have been renamed to ‘Smoke control dampers’ following industry feedback to ensure that the tiles of Uniclass codes align with the terminology currently used in the industry. Additionally, new codes have been added for different types of ‘above-ground’ pipes to complement the classifications for ‘below-ground’ pipes added as part of the previous quarterly update of the tables.
To facilitate the classification of accessible spaces, two new codes have been added to the Spaces/ locations table in collaboration with the University of Liverpool. A total of 42 new classifications and 5 amended codes are included in this release, reinforcing Uniclass as a robust and evolving classification system for global application across various sectors and industries. For full details of changes, refer to the relevant revision sheets and change logs.
Previously used codes
We aim to minimize changes to existing codes and classifications, but we always take feedback from users into account. Any changes are the result of this input, combined with our own ongoing review, and this sometimes means that a code is moved to another location in the tables – or deleted completely.
Following feedback from government department users of Uniclass, we have made every code that has been used since Uniclass was first published in 2015 available, together with information on the codes that they have been replaced by, where appropriate. Deleted and revised codes are now included in the site search facility, and a separate Excel file that lists all the withdrawn codes is also available.
Continuing input and feedback
Between updates, we regularly liaise with a growing number of individuals and organizations using the tables in order to provide support, and to evaluate requests for new codes. We are grateful to all of the organizations that we have worked with for their input. As we share details of this activity, industry professionals can learn more about who else is using the tables, what purposes they are using them for, the range of changes to expect and the reasons for those changes.
The work of maintaining and enhancing Uniclass to continually support the needs of those operating in the built environment is an ongoing exercise. We welcome comment and input from all sectors in the construction industry via the website – https://uniclass.thenbs.com/feedback.
Changes to published versions
Status and revision information is available alongside each Uniclass table. Each information sheet (PDF) provides a summary of the changes made, as well as code-by-code details. A full list of all changes is also available in the Excel change log.
