Details
Our Approved Contractor Scheme (ACS) is a quality assurance scheme for the private security industry. We approve private security companies.
Use the ‘ACS application form’ if you are not an approved contractor and you wish to become one.
Use the ‘ACS continuation of approval’ form if you are an approved contractor and you wish to provide your annual return, renew your approval or extend the scope of your approval to include another sector.
