Code of practice - labour provision in the security and events sectors

In response to feedback and evidence of poor practices that threaten the safety of the public, NSI developed a Code of Practice for the Provision of Labour in the Security and Events Sectors (NCP 119).

This code when utilised demonstrates to buyers of security guarding and event stewarding services areas such as screening, right to work, payment of minimum wage and SIA licensing are correctly adhered to for all personnel deployed including those sourced from labour providers. 


It is a mandatory requirement (as of 31st December 2021) for all NSI approved companies to only use labour providers holding approval to this code. 

Labour providers interested in gaining approval should contact the Applications team, call 01628 764885 or email:
