What is a Category D Prison?
A Category D prison, often called an open prison, is designed for people who are considered a low security risk. These prisoners are trusted not to escape and are typically serving the final part of their sentence.
Unlike closed prisons, where movement is tightly controlled, open prisons allow prisoners to take part in work, training, or education outside the prison during the day. They may also join rehabilitation projects or community activities that help them prepare for a safe and successful return to society.
The focus of open prisons is not on punishment but on rehabilitation. By giving prisoners more responsibility and independence, Category D prisons aim to reduce reoffending and ensure people are better prepared to rebuild their lives once released.
If you’re unsure whether you or a loved one may qualify, contact our legal team for clear guidance.
What are Category A–C Prisons?
To understand the difference, it helps to look at the other prison categories:
Category A prisons are the highest-security prisons, holding the most dangerous or high-risk prisoners. Escape from these prisons would pose a serious threat to the public or national security.
Category B prisons hold prisoners for whom escape needs to be made very difficult, but who are not as high-risk as Category A.
Category C prisons are for prisoners who cannot be trusted in open conditions but are unlikely to make a determined escape attempt.
These Category A–C prisons are all closed conditions, meaning they have stronger physical barriers, tighter rules, and more restrictions. Category D (open) prisons, by contrast, have minimal physical security and focus on reintegration rather than containment.
Who Can Apply for Category D?
For many prisoners, applying for open conditions is a vital step in their sentence plan. The benefits include:
- Independence – Open prisons give individuals the chance to rebuild responsibility and self-control in a more normal environment.
- Education and work opportunities – Many prisoners can study at colleges, gain qualifications, or take up paid employment while in open conditions.
- Rebuilding family ties – Being closer to family and having more flexible visiting arrangements can strengthen relationships, providing vital support on release.
- Resettlement activities – Prisoners can begin arranging housing, probation meetings, and other practical steps needed before release.
- Lower risk of reoffending – Studies show that prisoners released from open conditions often have a smoother transition and are less likely to return to crime.
Applying for open conditions is about taking real steps toward rehabilitation and showing readiness for life after prison.
The Application Process
The process of applying for open conditions usually begins as a prisoner approaches the final phase of their sentence.
Starting the review
Gathering information
Reports are collected from relevant professionals. Behaviour, risk assessments, and rehabilitation progress are all considered.
Review board decision
Outcome given
This process can feel stressful, especially if the outcome is uncertain. Having legal support can ensure the application is thorough, clear, and backed by strong evidence.
Common Reasons for Refusal
Applications for open conditions are not always successful. Common reasons for refusal include:
- Concerns about risk of escape – If staff believe the prisoner may abscond, the application is likely to be refused.
- Poor behaviour in custody – Recent disciplinary issues or failure to follow prison rules can count heavily against an application.
- Lack of rehabilitation progress – If the prisoner has not engaged with courses, therapy, or other sentence plan requirements.
- Public safety concerns – If there is evidence that release into open conditions could put the public at risk.
- Incomplete sentence plan – If required courses or programmes have not yet been finished.
When applications are refused, feedback is usually provided so the prisoner knows what needs to improve before applying again.
How Appeals Work
If an application for open conditions is refused, it does not have to be the end of the process. We appeal the decision on behalf of prisoners, asking for it to be reviewed by a higher authority.
The appeal process usually involves:
- Requesting a review – We submit an appeal explaining why the refusal was wrong.
- Providing evidence – Additional documents, reports, or arguments are submitted to strengthen the case.
- Higher-level review – A senior prison manager or independent review board considers the appeal.
- Decision made – If successful, the refusal can be overturned, and the prisoner moved to open conditions. If not, the prisoner will be told why and when they can reapply.
Appeals must be carefully prepared. A clear explanation of errors in the decision, along with strong supporting evidence, can make the difference between success and failure.

Open Prison Application and Appeals FAQs
Who is eligible to apply for a Category D (open prison) transfer?
Category D applications are usually open to prisoners assessed as low risk, nearing the end of their sentence, and able to demonstrate trustworthiness and readiness for work, study, or training outside the prison.
When can a prisoner apply for open conditions?
Applications typically take place during the later part of a sentence. The timing depends on progress in custody, behaviour, and completion of sentence plan requirements.
What are the main reasons a Category D application might be refused?
Common reasons include concerns about risk of escape, poor behaviour, lack of progress in rehabilitation, incomplete sentence plan work, or risks to public safety.
Can a prisoner appeal if their Category D application is refused?
Yes. A refusal can be appealed by explaining why the decision was wrong and providing new evidence or information. Appeals are reviewed by a senior prison manager or review board.
How long does the Category D application or appeal process take?
Timeframes vary depending on the prison and review board schedules. Having a well-prepared application or appeal can help avoid unnecessary delays.
What happens after a prisoner is moved to a Category D prison?
Once in open conditions, prisoners can access work placements, education, or training outside the prison. They are given more responsibility for managing their time, with the aim of preparing them for release and helping them reintegrate safely into the community.
