It is good news for volunteers that CRB checks are to become portable. So if you have a CRB (Criminal Record Bureau) check for one charity, school, club or job you can use it for another. This change will save volunteers time and inconvenience and save taxpayer money.
The CRB has now been replaced by Disclosure and Barring Service and so checks in future will be known as DBS checks.
