Portability explained

Portability refers to the re-use of a CRB check, obtained for a position in one organisation and later used for another position in another organisation.

How does portability work?

If you ask an individual to be CRB checked and they tell you that they already have a CRB check, you could:

  • Ask the individual to show their copy of the CRB check.
  • Contact the Countersignatory named on the front of the CRB check and confirm that the reference number and identity details match
  • Ask if the Countersignatory received any additional information - the Countersignatory can only confirm or otherwise the existence of such information – but not the content of the information.
  • If there is no additional information, carry out a formal risk assessment to decide whether to accept the CRB check.
  • If there was additional information, you are strongly advised to ask the individual to apply for a fresh check.
