As such, we are dedicated to continuous improvement and work proactively to deliver the highest professional standards. In order to achieve this, we ensure that we work in accordance with the most demanding industry standards and have attained a wide range of external accreditations and approvals. 

Contractors Health & Safety Assessment Scheme

The Contractors Health & Safety Assessment Scheme (CHAS) is perhaps the best known standard within the construction industry and is also among the hardest to obtain.

CHAS is dedicated to completing health and safety pre-qualification assessments to a nationally recognised and accepted threshold standard. By using a CHAS accredited supplier our clients have the knowledge the high standards they expect of us will be met.

Security Industry Association Accredited Contractor Scheme

Although voluntary, the Security Industry Authority's Approved Contractor Scheme (SIA ACS) is highly regarded, and organisations are increasingly insisting on only employing the services of security providers that are registered contractors.

In order to be on the Approved Contractor Scheme companies undergo rigorous audits ensuring that they meet the high standards set by the accrediting body. Charter Security currently holds SIA approved Contractor Scheme (ACS) status for the provision of Security Guarding, Keyholding, Door Supervision and CCTV.

BS EN ISO 9001  Quality Management Systems

ISO 9001 is a best practice management framework used by millions of businesses worldwide as a tool to encourage best practice and improve business performance. ISO 14001 seeks to limit and control the impact companies have upon the environment. OHASAS 18001 is the internationally recognized standard for best practice occupational health & safety management. The standard ensures that companies have procedures in place to support both governmental legislation and their own internal rules and regulations with the intention of reducing accidents and improving safety in the workplace.
