The UK government had updated their DBS Update Service and for a registration fee of just £13 you can check DBS certificates (standard and enhanced DBS checks) online.
Individuals can also add or remove a certificate, give employers permission to check if anything has changed on a certificate, and see who has checked their certificates for updates.
If you need to manage DBS checks this may be of help, so find out more at https://www.gov.uk/dbs-update-service
