As you may be aware the Common Assessment Standard (CAS) was updated on 1 July 2025.
ECA (Electrical Contractors’ Association) is currently reviewing the new questions and will issue a revised version of the ECA CAS Manual in the near future.
The CAS, produced by Build UK, now includes a Building Safety section that is mandatory for completion by all companies that carry out work under the Building Safety Act. A number of Build UK members will be specifying that members of their supply chains must have successfully completed the Building Safety section by 1 October 2025.
Version 5 also contains updates to the Corporate & Professional Standing; Environmental; and Fairness, Inclusion & Respect sections.
Visit the Build UK website for more information, and to download the assessment questions.
