What Is the Common Assessment Standard?

The Common Assessment Standard is an accreditation designed to standardise the prequalification process, helping both clients and contractors improve supply chain efficiency, reduce supply chain risks, and find reliable business opportunities.

The Common Assessment Standard builds on the PAS 91 prequalification questionnaire, helping contractors achieve compliance and mitigate risks across 12 key areas of risk management. And to achieve certification, you just need to evidence your compliance in these areas once a year. This can all be achieved via our intuitive, easy-to-use, online contractor portal.

With the Common Assessment Standard, you can achieve compliance and certification without the need for time-consuming processes, multiple assessment bodies, and confusing requirements.

What Does the Common Assessment Standard Cover?

The Common Assessment Standard is the most comprehensive accreditation programme we offer, covering 12 key areas of risk management, including and building on areas assessed under the PAS 91. By covering many different aspects of risk management, the Common Assessment Standard can reduce risk across the whole supply chain.

  • Identity — General information about your company is used to verify that you’re legally able to operate within the UK. This information includes your company’s name, contact details, registration, company size and address.
  • Financial — The Assessment will check that you’ve taken the necessary steps to reduce financial risks, so you will need to answer a few questions about your company’s financial information and provide any required supporting documentation.
  • Corporate and Professional Standing — The Common Assessment Standard will look into your corporate and professional standing with questions relating to criminal activity, corruption, terrorism and human trafficking.

  • Health and Safety — A huge amount of importance rests on health and safety during the Common Assessment Standard. You will need to demonstrate that your company has taken steps to protect workers, site visitors and the public from harm.
  • Environmental — The Common Assessment Standard will include a set of environmental questions that will ask about whether your company has taken the necessary steps to reduce the environmental impact of projects and meet environmental management standards.
  • Quality — Quality assurance can prevent problems from arising and reduce the risks involved in projects, so the Common Assessment Standard will require confirmation that your company meets quality management standards

  • Equality — The Assessment will ask you to confirm that your company promotes equality and diversity in the workplace and that all people are treated fairly.
  • Corporate Social Responsibility (CSR) — The Common Assessment Standard considers how your company impacts society, so you will need to answer a few questions about your CSR policy.
  • Information Security and GDPR — You will need to demonstrate that your company is protecting personal data in line with the GDPR.
  • Building Information Modelling — Questions about Building Information Modelling explore how your company develops, manages and controls design information, if applicable.
  • Anti-Bribery and Corruption — The Common Assessment Standard will check that you have implemented procedures to prevent persons within or associated with your organisation from receiving bribes or bribing others.
  • Modern Slavery — You will need to confirm that your organisation has taken steps to assess and manage modern slavery and human trafficking risks.

How Is the Assessment Carried Out?

There are two levels of certification: desktop and site-based. Both types of assessment will involve completing a set of prequalification questions covering the above areas of risk management and providing supporting documents and evidence for your answers.

If you opt for a desktop audit, your CHAS assessor will review the information you provided and check it against the relevant assessment standard. This will be done remotely, without any site-visits.

Site-based audits, on the other hand, will involve a CHAS assessor visiting your premises. They will check you are implementing the policies and procedures submitted during the desktop assessment.

Assessments will be carried out by CHAS, once a year. To maintain certification, you will need to update time-critical documents when they expire. For example, insurance certificates, company policies and risk assessments will all need to be reviewed and updated whenever they expire or changing circumstances affect their validity and relevance.

Who Does the Common Assessment Standard Apply to?

The Common Assessment Standard helps all companies in construction and related industries achieve and demonstrate compliance, so the standard is accessible to UK companies of all sizes.

The Common Assessment Standard takes into account small micro-businesses with less than five employees and a turnover of less than £500,000 and offers these companies streamlined assessment criteria to help them achieve accreditation.
