You should also provide a copy of the relevant order, caution, conviction etc. In relation to cautions/convictions a DBS Certificate may be provided.
The amendments to the Rehabilitation of Offenders Act 1974 (Exceptions) Order 1975 (2013 and 2020) provides that when applying for certain jobs and activities, certain convictions and cautions are considered ‘protected’. This means that they do not need to be disclosed to employers, and if they are disclosed, employers cannot take them into account.
Guidance about whether a conviction or caution should be disclosed can be found on the Ministry of Justice website.
