From 1 April 2008, Approved Contractors may only sub-contract provision of an approved security activity to other Approved Contractors.

There are some exceptions to this requirement, including:

• self-employed operatives
• directly supervised sub-contracted labour (where individual temporary staff are under direct supervision of the main contractor)
• sub-contractors not providing a security service
• by special arrangement with SIA (subject to application and agreement under our exceptional circumstances policy)
