Hi
One of the best ways to approach this criteria is to list the legislation/regulation
Work setting policy - name the document
County/Regional - LSCB
National Government documents you work to - name
EYFS
Under each heading explain the requirements and how one links into the other.

Above link is useful to find out about whistle blowing - there are a number of others if you google whistle blowing
Hope this helps
