The Disclosure and Barring Service (DBS) are a replacement for the CRB checks. Applicants can keep their DBS certificates up to date online and it allows employers to check a certificate online. Applicants need to register online as soon as you have your application reference number or you can wait for your DBS certificate and register then. Registration lasts for one year and costs £13 per year. This allows you to take your certificate from one job to another. This way an employer can check your certificate online and get the result straight away. For more information please go to https://www.gov.uk/dbs-update-service.
