6 tables updated. 9 tables unchanged.

No tables added. No tables withdrawn.

01 April 2026

This release includes updates to six tables: Activities, Form of information, Project management, Products, Spaces/ locations and Systems.

This is the second of our quarterly updates for Uniclass in 2026. It includes improvements across six tables, a result of external input from users and internal development roadmaps. 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 pre-demolition and pre-refurbishment auditing. Additionally, a new Project Management code has been added, ‘Design for disassembly strategy’. For consistency across all Uniclass tables, 38 codes in the Spaces/ locations table have updated to their plural from a singular form. In addition to these changes, the existing ‘Clean utility’ code has been renamed to ‘Clean utility rooms’, highlighting that it is intended for medical spaces and a new code for ‘Dirty utility rooms’ was added as an antonym following feedback from users. ‘Notification (NO)’ has been added to the Form of information table following careful consideration. This code is intended to cover all types of notifications, including but not limited to those issued for a compensation event and termination of contract as well as formal notifications of instruction or acceptance. New M&E codes have been added to the Products table to facilitate the classification of additional ventilation and pipework products. A total of 12 new classifications and 40 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.

01 January 2026

This release includes updates to eight tables: Activities, Form of information, Project management, Products, Roles, Spaces/ locations, Systems and CAD.

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.
