In 1997 a group of health and safety and procurement professionals from across Great Britain worked with the Association of London Government (ALG) to develop The Contractors Health and Safety Assessment Scheme (CHAS). In 2001 CHAS became a web-based system.


CHAS started with two main aims:

To improve health and safety standards across Great Britain.
To reduce duplicated safety applications for both suppliers and buyers.


These days CHAS have more than 500 public and private sector buyer organisations, such as councils, housing associations, and NHS trusts, including a growing number of large private companies who employ sub-contractors.

Each month thousands of contractors and consultants (suppliers) apply for work with public and private sector organisations (buyers). To win work, they must meet the buyer’s health and safety standards.

Assessing suppliers’ health and safety competence is usually a lengthy and time consuming process. Suppliers can sometimes meet one buyer’s Health and Safety standards but not another. Being CHAS approved reduces duplication as suppliers compliance is accepted by all CHAS buyers.
