Leveraging the Common Assessment Standard: Streamlining Your Bidding Process

Navigating the complexities of public sector procurement can be challenging—especially for SMEs aiming to compete with larger firms. The Common Assessment Standard UK (CAS) has emerged as a transformative solution, simplifying the pre-qualification process and improving supply chain efficiency across the construction and facilities management sectors. Whether you’re a growing business or a seasoned supplier, aligning with this standard can significantly improve your competitive edge.

What is the Common Assessment Standard UK?

The Common Assessment Standard UK was developed by Build UK and endorsed by the Civil Engineering Contractors Association (CECA) to standardise the pre-qualification (PQ) process in the construction sector. Rather than filling out multiple, repetitive questionnaires for different buyers, suppliers now complete one standardised assessment covering key areas such as:

• Health and safety
• Financial standing
• Environmental management
• Equality, diversity, and inclusion
• Quality assurance
• Information security

This consistent framework is recognised across both the public and private sectors, reducing duplication and saving time for both suppliers and buyers.

Benefits of Adopting the Common Assessment Standard

Adopting the Common Assessment Standard UK offers a host of benefits to your business, especially when tendering for public sector contracts:

1. Faster Pre-Qualification

Buyers can instantly assess your suitability without requiring bespoke forms. This increases your chances of being considered for more opportunities.

2. Greater Visibility

Being CAS-certified means your profile is available to a wide network of Tier 1 contractors and public sector buyers who prioritise standardisation.

3. Improved Credibility

Certification demonstrates your compliance with industry best practices, which helps you stand out in competitive tender environments.

4. Cost Efficiency

Instead of duplicating effort across multiple PQ schemes, the CAS ensures a streamlined, consistent process—saving time, money, and admin resources.

5. Better Risk Management

By ensuring suppliers meet a baseline level of compliance, CAS enhances transparency and reduces procurement risk for buyers.

For SMEs, these advantages level the playing field, creating fairer access to contracts and making public procurement more inclusive.

How to Achieve CAS Certification

Achieving certification under the Common Assessment Standard involves a structured process that includes:

Step 1: Self-Assessment or Third-Party Certification

There are two levels of assessment:

• Desktop assessment: A self-assessment verified by a CAS-recognised certification body.
• Site-based assessment: An on-site audit for higher-risk suppliers or those working on larger contracts.

You’ll need to select a recognised certification body, such as Constructionline, CHAS, or Achilles.

Step 2: Prepare Your Documentation

Ensure you have robust evidence across all CAS criteria, including risk assessments, financial accounts, insurance documents, and policy statements (e.g., equality, sustainability).

Step 3: Submit and Review

Once submitted, your application will be reviewed, and feedback provided. Address any gaps promptly to finalise your certification.

Staying Compliant with CAS

Compliance isn’t a one-time effort. Regular audits, document updates, and process reviews are essential. Key practices include:

• Updating policies and training materials annually
• Conducting internal audits or mock assessments
• Staying informed on regulatory changes and industry best practice

You can also maintain an online compliance log using digital systems to streamline documentation and keep everything up to date.
