The official web pages for the Disclosure and Barring Service have moved, as mentioned in the last newsletter, and the main page is at https://www.gov.uk/government/organisations/disclosure-and-barring-service. (A short version of that is https://www.gov.uk/dbs). The new umbrella body directory is here.
Also, the government has decided to change the law so that certain old and minor cautions and convictions will no longer be disclosed on a DBS certificate, in response to the Court of Appeal ruling in January. This needs new legislation so will not happen instantly, see DBS item.
