About the super-complaint
The super-complaint is being submitted on Monday 15 December 2025. The next step will be for the three super-complaint bodies to decide if it is eligible and then conduct their own investigation into the issues raised. If the super-complaint is upheld, they will make recommendations to address the problems highlighted.
The police super-complaints system is designed to identify and address systemic issues in policing. It allows organisations designated by the Home Office to raise issues on behalf of the public about patterns or practices in policing they believe are causing significant harm. Centre for Women’s Justice is a designated body.
His Majesty’s Inspectorate of Constabulary and Fire & Rescue Services (HMICFRS), the College of Policing and the Independent Office for Police Conduct (IOPC) (the decision-making authorities) are jointly responsible for responding to police super-complaints. They work together to respond to police super-complaints, to support their joint aim of promoting improvements in policing.

Our data in the super-complaint
This super-complaint draws upon data obtained by Freedom of Information requests to the Home Office as well as survey research and focus groups with Independent Sexual Violence Advisors (ISVAs) and survivors across England and Wales to show the true scale of the problem and factors within policing that are contributing to the delays.
- Freedom of Information (FOI) requests to the Home Office
The super-complaint authors submitted an FOI request for data on sexual offence investigations over the past decade that took more than three years from report to outcome.
We also sent FOI requests to all police forces in England and Wales; 33 responded.
Key findings include:
In the past decade, more than 37,000 sexual offence investigations have dragged on for over three years — over half ran beyond four years, with many lasting far longer. We include a detailed example of one case that took over six years for the police to progress.
Police investigations into sexual offences taking more than three years have surged by over 652% in the past decade (533 cases in 2014/15, and 4,008 2024/25). This is more than a sixfold increase, and we have also seen a 15-fold increase for investigations lasting between three to four years (137 cases in 2014/15, and 2,261 cases in 2024/25).
There are underlying issues within policing contributing to excessive delays, such as the routine de-prioritisation of some sexual offence investigations; staffing and resourcing issues, failures of management and supervision, poor joint working with the CPS and changes to the law around bail.
- Data from ISVA services
We sent a survey to 12 Rape Crisis centres providing Independent Sexual Violence Adviser (ISVA) services in England and Wales. The survey asked about police investigations lasting over three years and held two focus groups with eight experienced ISVAs and managers.
ISVAs are specialist support workers who help survivors navigate the criminal justice process.
While ISVA services do not routinely record investigation times or police outcomes, the information they provided reflects that ISVAs are aware of large numbers of sexual offence investigations lasting several years, and that these delays are acutely detrimental to the individuals they support.
Data was submitted by services across London, Brighton, Essex, Merseyside, Leeds, Gloucestershire, Darlington & County Durham, and Cambridgeshire, covering cases from 21 police forces.
London services in particular reported higher numbers of delayed investigations, but it is not possible to compare ISVA services directly due to differences in staffing and caseloads.
- Results from survivors
We ran an online survey for survivors about sexual offence investigations lasting over three years. We received 75 responses covering 26 police forces across England and Wales.
Key findings:
More than two-thirds of survivors in delayed cases surveyed by the charities said they were not sure if they would report to the police for help again.
Significant delays in police investigations cause significant harm to those reporting, sometimes more than the impact of the original offence.
