The National Security Inspectorate (NSI) introduced a new Code of Practice (NCP 119) for the ‘Provision of Labour in the Security and Events Sectors’, effective 1st April 2020. Commercial providers of guarding staff routinely scale up resources, when required. This operational procurement of additional, sub-contracted labour can pose a variety of risks compromising the safety and security of the public, offering unwelcome scope for worker exploitation, and bringing the industry into disrepute if inadequately managed. NCP 119 is mandatory for NSI Guarding Gold and Silver approved companies from 31st December 2021. It provides buyers with an important assurance that their security guarding providers are of a suitable standard, operate as responsible employers and so minimise the security risk associated with labour provision (sometimes referred to as agency labour). NCP 119’s requirements include measures related to best practice in terms of organisational structure, finances, payroll, insurance and premises. They also include personnel, sale of services, operations and documentation and record-keeping. The personnel requirements cover recruitment, training, employee terms and conditions, and uniforms.
