Berkshire falls within the CPS Thames and Chiltern Area, one of 14 CPS Areas across England and Wales, which prosecute people charged with a criminal offence.

CPS lawyers review the evidence gathered by the police and decide whether the case should go to court.

Responsibilities include:

  • Advising the police on possible prosecutions
  • Reviewing cases submitted by the police and deciding on the charge
  • Preparing cases for court
  • Prosecuting cases at Crown Courts and Magistrates' Courts

Cases are prosecuted firmly, fairly and effectively when there is sufficient evidence to provide a realistic prospect of conviction and when it is in the public interest to do so.


In the financial year to March 2017, CPS Thames and Chiltern prosecuted 16,937 Thames Valley defendants in the Magistrates' Courts and 2,646 defendants in the Crown Courts. The conviction rate for this period was 83.0% in the Magistrates' Courts and 76.3% in the Crown Courts.

It should be noted that a large number of low complexity cases (including many traffic cases with guilty pleas) were prosecuted by the police this year and are not now included in these figures.

The county split for Thames Valley is no longer available due to changes to our Case Management System structure.
