State the requirement before you choose a provider
Screening and insurance requirements affect cost, so they belong in the document every bidder prices against. A provider who has not been told that all attending staff need a particular check may have priced a workforce that cannot be deployed. Discovering this after award produces either a delayed start or a quiet decision not to comply, and the second outcome is worse than the first.
Write the requirement in plain terms: what check is needed, who it applies to, how currency is demonstrated and how often it is refreshed. Then state what evidence you expect to hold and in what form. Organisations with their own compliance obligations often have this documented already, in which case attaching the existing requirement to the scope is the fastest route. It also saves rewriting the requirement each time the organisation goes to market.
