If you or someone close to you is in prison, under probation supervision, or held in an immigration removal centre in England or Wales, knowing how to raise a formal complaint matters. The Prisons and Probation Ombudsman (PPO) is the body that steps in when internal complaint processes have run their course and the individual still feels the outcome is wrong or unfair.
I've put this guide together to walk you through what the PPO actually does, who it can help, and the practical steps for bringing a complaint to its attention. I'll also cover the time limits that apply, the kind of issues the Ombudsman will and won't look at, and what you can reasonably expect once an investigation begins.
The process isn't quick, but it is independent, and for many people it's the only meaningful route to having a serious grievance looked at properly.
Overview
The Prisons and Probation Ombudsman is an independent body that sits outside the Ministry of Justice, the Prison Service and the probation system. Its job is to look impartially at complaints from people in custody or under supervision, and to investigate every death that happens in prison, in an immigration removal centre, in a secure children's home or secure training centre (where ordered by the Secretary of State), and some deaths of people recently released on probation.
The Ombudsman doesn't have the power to overturn court decisions or parole board rulings, and it can't change sentences. What it can do is examine how decisions were reached, whether proper procedures were followed, and whether someone has been treated fairly.
Where things have gone wrong, the PPO can make recommendations to the organisation involved, such as changes to practice, an apology, or a reconsideration of the decision. Findings are set out in a written report, and the body concerned is expected to respond to the recommendations made.
Key steps
Raise the issue internally first. Before the Ombudsman will consider your complaint, you need to have gone through the complaints procedure of the prison, probation service or removal centre involved. This usually means submitting a complaint form and, if you're unhappy with the response, taking it to the next stage of appeal within that organisation.
Gather your paperwork. Keep copies of every complaint form you submitted, every response you received, and any relevant supporting documents such as letters, medical records or witness accounts. The PPO will want to see what was said and decided at each internal stage, so having these to hand makes your case much easier to put together.
Submit your complaint within three months. You have a three-month window from the date you received the final internal response to bring your complaint to the PPO. Late complaints can sometimes be accepted where there's a good reason for the delay, but it's safer to act promptly. You can write to the Ombudsman by post or contact them through the channels listed on their website.
Explain clearly what went wrong. In your complaint, set out the facts in chronological order, say what outcome you were hoping for from the internal process, and explain why you think the response you got was inadequate. Be specific about which decisions or actions you're challenging, and what you'd like the Ombudsman to do.
Wait for the eligibility decision and investigation. The PPO will first check whether your complaint falls within its remit and meets the basic requirements. If accepted, an investigator will be assigned. Investigations can take several months depending on complexity, and you'll be told the outcome in writing along with any recommendations made.
Q Who can bring a complaint to the Prisons and Probation Ombudsman?
The PPO accepts complaints from prisoners in England and Wales (both adults and young people in custody), people supervised by the probation service in England and Wales, and those detained in immigration removal centres. Family members and legal representatives can also correspond with the Ombudsman on behalf of someone who falls into one of these categories, with appropriate authority.
Q What kinds of issues will the Ombudsman not investigate?
The PPO cannot interfere with court sentences, parole board decisions, or convictions, these are matters for the courts and separate appeal processes. It also won't look at issues that fall to other bodies, such as complaints about healthcare professionals (which go to health regulators) or policing matters. If a complaint is outside its remit, the Ombudsman will usually explain where to go instead.
Q How long do I have to bring a complaint?
Generally, you must contact the PPO within three months of receiving the final response from the internal complaints process. If more time has passed, it's still worth getting in touch, as the Ombudsman has discretion to accept late complaints where there are exceptional circumstances, such as illness or delays outside your control. Acting quickly always strengthens your position.
Q Does the Prisons and Probation Ombudsman investigate deaths in custody?
Yes. The PPO independently investigates every death of a person in prison, in an immigration removal centre, and in certain secure settings for children and young people, as well as some deaths of people recently released under probation supervision. The aim is to establish what happened, whether lessons can be learned, and to provide answers to bereaved families.
Q Is there a cost to making a complaint?
No, there is no fee for complaining to the Prisons and Probation Ombudsman. The service is free to use for anyone eligible. You may want to get help drafting your complaint, and while that isn't required, it can make a real difference where the issues are complex or where a lot of documentation is involved.
Q What happens if the Ombudsman upholds my complaint?
If the PPO finds in your favour, it will make recommendations to the organisation concerned. These might include an apology, a change in how a decision was made, or wider improvements to policy or practice. The body receiving the recommendations is expected to respond and explain what action it will take, though the PPO itself cannot force compliance.
Q Can I go to court if I'm not satisfied with the Ombudsman's decision?
The PPO's findings are not legally binding in the way a court judgment is, and you can't appeal its decision in the ordinary sense. In limited circumstances, a decision of the Ombudsman may be challenged by judicial review in the High Court, but that's a specialist area and legal help would be essential before going down that route.
Unsure if the Ombudsman is the right route for you?
Complaints about custody, probation or removal centres can be complicated, and it's easy to miss a step or a deadline that costs you the chance of being heard. An experienced legal adviser can talk through your situation on the phone and help you think about what to do next based on what you describe.
