What is CASv5?
The construction industry is evolving, and so is the way contractors are assessed. With the launch of Common Assessment Standard v5 it creates a unified, industry-recognised framework that simplifies pre-qualification and raises the bar for safety, compliance and professionalism.
The Common Assessment Standard, developed by Build UK and other key stakeholders, has transformed the construction pre-qualification process, improving efficiency, reducing cost and raising quality standards. It enables you to demonstrate compliance in 13 areas of risk management and is backed by many Tier-1 contractors.
How do we get started?
There are two levels of certification: desktop and site based. You apply to a recognised assessment body for the certification level that is most appropriate for your business based on a range of factors including trade, size and the requirements of your clients. These include organisations like CHAS, Constructionline and Achilles (see Build UK for the full list*).
Why it matters
CAS v5 isn’t just about ticking boxes - it’s about building trust, streamlining procurement and driving better outcomes across the sector. We are seeing more tenders being issued and compliance criteria assessed against CAS v5.
How we can help
As a business we are passionate about supporting you to grow your business and see CAS v5 as a strategic opportunity for you to stand out, win more work, and contribute to a safer, more transparent construction ecosystem.
We help clients to find the right opportunities, provide a work-winning service to manage all, or part, of your bids. If you want to win more work in the public or private sector contact our team for a free consultation.
