This is the first of our quarterly updates for Uniclass in 2026. It includes improvements across eight tables, a result of external input from users and internal development roadmaps.
The Environment Agency (EA) use Uniclass for asset classification. Our technical specialists have created seven new surface water management codes in the products, systems and spaces tables to assist the EA and increase the scope for asset mapping. Amendments to existing Uniclass codes have also been made as part of this work. This support is part of the bespoke services we regularly provide to meet user needs.
A new PM code has been introduced for ‘Medical gas pipelines certificate of completion’ within the Project management table. This certification plays a critical role in ensuring compliance and safety in healthcare environments. Additional codes for testing and certification of medical gas pipelines are currently under considerations.
Following a request from the University of Liverpool, we’ve extended the CAD table to support their initiative to standardise AutoCAD layer naming in alignment with ISO standards. Two new codes have been added under the ‘Boundaries’ subgroup for building footprint and gross external area. Further discussions are underway to explore the need for additional codes.
As part of the development of new content to support circular construction principles and re-use considerations, the Activities table has been extended to cover deconstruction of architectural components, mechanical services and external works. Further work to accommodate re-use and alteration in construction is planned for future Uniclass updates.
Additionally, the ‘Roles’ table has been extended to include new classifications within the Organization roles and Asset management roles sub groups, including codes for quality managers and utilities consultants.
A total of 26 new classifications and 5 amended codes are included in this release, reinforcing Uniclass as a robust and evolving classification system for global application across diverse sectors and industries. For full details of changes, refer to the relevant revision sheets and change logs.
Updates to the Uniclass tables are a result of external input from users and internal development roadmaps. Full details of changes are detailed in the revisions sheets and the 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.
