Build UK has published an updated version of the Common Assessment Standard, the industry-agreed standard for pre-qualification in construction.
Version 6 aligns with the latest legislation, guidance and client requirements and includes significant changes to the Building Safety section to reflect that scaffolding and temporary works are not in scope of the Building Regulations which regulate ‘building work’, unless they form part of the structure once complete.
With over 26,000 companies certified to the standard, a growing list of clients and contractors are specifying the Common Assessment Standard to demonstrate the organisational capability of their supply chains. Introduced in 2019, the Common Assessment Standard is improving quality standards and reducing duplication across the sector.

Jo Fautley, Build UK Deputy Chief Executive, said: “The regulatory regime is constantly evolving, and the Common Assessment Standard has been updated to keep pace with the latest developments. Companies carrying out work under the Building Safety Act can use the Common Assessment Standard to demonstrate that they have the organisational capability to fulfil their dutyholder roles under the Act.
“Once certified by a Recognised Assessment Body, a company can share its data at no cost with the other Recognised Assessment Bodies, so it is visible to more clients and contractors, removing the need to have multiple certifications.”
Version 6 of the Common Assessment Standard includes the following updates:
