Uniclass - July 2025 update

Aug 12, 2025 |NBS

This is the latest in our quarterly updating programme for Uniclass. It includes updates to four tables.

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been used since Uniclass was first published in 2015 available, together with information on the codes that they have been replaced by, where appropriate. Deleted and revised codes are now included in the site search facility, and a separate Excel file that lists all the withdrawn codes is also available.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.

For specifiers, that means ensuring every product installed stands up to scrutiny, not just in material, but in source, traceability, and lifetime carbon footprint. JELD-WEN, a specialist timber door, door kit and doorset manufacturer, explains the critical considerations when selecting sustainable materials.

Dulux Trade launches new solution for high-humidity spaces

Because of how they are used, kitchens and bathrooms experience more moisture, more contact, and more ongoing maintenance. Standard emulsions are not designed for this level of use. Over time, finishes can lose their appearance or fail to cope with the environment. Kitchens and bathrooms benefit best using a product formulated specifically for their daily demands.

The hidden cost of compliance: why architects are demanding a new era of product transparency

Few pieces of legislation have reshaped the UK construction industry as significantly as the Building Safety Act 2022 (BSA). Introduced to improve accountability, traceability and safety standards across the built environment, the legislation has fundamentally changed the responsibilities placed on architects, contractors and manufacturers. While the principles behind the Act are widely supported, the reality for architectural practices is proving more challenging than many anticipated.
