Just from Google: In 2012, CRB Checks were replaced by DBS Checks when the Criminal Records Bureau merged with the Independent Safeguarding Authority (ISA). This new body became known as the Disclosure and Barring Service (DBS).
Since the new body is DBS, they may now be looking at criminal offences. On another note, if you plan on working alongside or retiring from this work I would never mention this work in any official documents or share online adult content showing your face. The DBS wouldn't search for that but some employers may google your name/social media.
