Can a caution be removed after 5 years

I am a qualified solicitor and Director of Legisia Legal Services. I have extensive experience of applying for the removal of police cautions from the PNC, challenging DBS certificates and DBS barring decisions. I have had many successful cases, and for cases where judicial review proceedings have been issued, I am usually able to recoup my clients’ costs from the police. I have co-authored a journal paper on the reform of the police cautioning procedure in the Criminal Law Review (the leading criminal law journal : “Suggestions for Reform to the Simple Cautioning procedure”). I also write the UK Westlaw Insight on Police Cautions and published an article in the Criminal Law and Justice Weekly on anonymity in criminal proceedings and its impact on the police caution: Adult Defendant Anonymity in Criminal Proceedings
