CRB Certificates to be transferrable

At present every person working or volunteering at an organisation in which they deal with children or vulnerable adults needs a CRB certificate through that organisation.  Therefore, somebody undertaking duties for different organisations needs multiple CRB certificates.  I have 5, I know people with even more.  This is time consuming and costly.  If CRB certificates were transferrable this pointless waste would be avoided.

Why is this idea important?
