The Home Office collects data on domestic abuse related offences, and on the outcomes on offences recorded by the police in England and Wales. Data is not available for all forces but the proportion of domestic abuse flagged offences that have the outcome OC17: Prosecution time limit expired is published for selected forces who provide data to HO.

We are aware that there is a concern that some victims of domestic abuse may be losing access to justice since by the time they come forward with allegations of assault, the time limit for prosecution of such cases is up. We are gathering data about such incidents and if analysis suggests that action is needed, we will seek to address it as appropriate.
