Benefits of CHAS

Setting industry bench​marks, providing assurance and reassurance, and offering best-in-class service​​s that are easy to use.

Over the years local authority health and safety and procurement professionals, with the support of the Health and Safety Executive, have developed the Contractor Health and Safety Assessment Scheme (CHAS). ARK’s Approved Contractor status highlights our desire to maintain and exceed expectations.

The nature of the Security Industry and the work that we do means that ARK representatives can often be placed in harm’s way. We take all risks very seriously, and our ongoing commitment to Health and Safety ensures that all officers have the knowledge and training required to try to minimise the threats that they face.
