Complaints about prison

This page explains how you can complain about prison, any time limits you have when making a complaint, what you can do if you are still not happy and advice on how you can complain for a relative or friend.


  • There are lots of reasons why you may want to complain about prison. For example, you might feel that staff did not do what they are supposed to do.
  • You should make your complaint as soon as possible after the incident has taken place.
  • You need to complain directly to the prison first.
  • If you are not happy with the prison’s response to your complaint, you might be able to go to the Prisons and Probation Ombudsman.

Why might I want to complain?

It can be a very difficult experience to be in prison. You may feel that prison officers or other staff in prison:

  • behaved inappropriately towards you,
  • did not act according to your rights,
  • treated you unfairly because of your mental health, or
  • did not consider your mental illness even though you told them about it.

You can complain if you are not happy with the service the prison gave. You can also complain if you think that prison staff have broken the rules or treated you badly.

Some things that you might want to complain about are called reserved subjects. This includes hearings or your security category. The prison cannot deal with these complaints but will pass them along for you. 

These are some of the things you should include in your complaint:

  • Which prison are you complaining about?
  • Where and when were the incidents you are complaining about?
  • Who was involved?
  • What was said and done?
  • Was there any damage or injury?
  • Are there any witnesses? Include their details.

Your complaint must relate to something that happened in prison. If you are not happy with your solicitor, or about healthcare in prison then the process is different.

How do I make a complaint?

Speak to a member of staff if you want to complain about something in prison. You could talk to your personal officer or another member of staff.

You can make a complaint if this does not help. You can fill in a COMP 1 form if you don’t feel comfortable talking with someone. You can put this in a complaints box. You should get a reply within 5 working days or 10 working days if you are complaining about a member of staff. This might be a full answer or a letter to say they are dealing with your complaint.

You can fill in an appeal form if you are not happy with the prison’s reply. You can put the appeal form in the same box you put your first complaint in. The prison will look at your complaint again. You have 7 days after getting your response to do this. The prison should reply to your appeal within 5 working days. The person dealing with your appeal should work at a higher level than the person who looked at your complaint the first time.

You can contact the Prisons and Probation Ombudsman if you are still not happy with the prison’s reply.  

Independent Monitoring Board

You can ask the Independent Monitoring Board to look at your complaint if you have already tried to resolve it with prison staff. 

The Independent Monitoring Board is independent from the prison. They monitor day-to-day life in the prison. They can deal with problems you are having. Your wing should have a leaflet about them. They cannot change a decision that the prison has already made. But they can ask the governor why they made a decision or suggest what else the prison could do.

Can I complain more privately?

You can also complain in a more private way. You can do this if your complaint is about something very serious or you can’t talk to prison staff.

To do this you can fill in a COMP 2 form. You can send this to:

  • the governor of the prison,
  • the head of the Independent Monitoring Board, or
  • the Director of Custody.

You should send this in a sealed envelope. The prison should have envelopes that have the addresses pre-printed for you.

Although your complaint is more private, the person you complain to may still need to speak to other people about it. This could include the person or people you are complaining about. But they should not share your complaint with anyone who does not need to know.

You should not use this process for an ordinary complaint as it does not speed up the complaints process for you.

Complaining about healthcare in prison

You should get the same healthcare and treatment in prison as anyone outside prison. You can have medication and support from the prison healthcare team if you have a mental illness. You should also be able to see a doctor, dentist, optician and other healthcare professionals for your physical health. 

You should use the NHS complaints procedure if you have a complaint about your healthcare in prison. If you are in a private prison, it will have its own complaints procedure for healthcare.

Complaining about a reserved subject

You can still fill in a COMP 1 form if you want to complain about a reserved subject. These are things that cannot be dealt with by the prison itself. An example of this would be a complaint about the behaviour of the Governor. The prison will pass this to the Prison Service Headquarters. You should get a reply within 6 weeks. If you are not happy with the reply, you can contact the Prisons and Probation Ombudsman. 

Can I change my mind about complaining?

Yes. You can stop your complaint if you change your mind. You can do this at any time, just tell a member of staff.

What is the time limit for complaining about prison?

You must complain within 3 months of the incident you are complaining about. Your complaint can be looked at after 3 months if you have good reasons for the delay. It might also be looked at after 3 months if your complaint is very serious.

You may have been through the prison’s complaint process and want to pass your complaint to the Prison and Probation Ombudsman. You have 3 months after getting the reply from the prison to do this. There is more information about the Ombudsman below. 

What if I am unhappy with how my complaint is handled?

You can contact the Prison and Probation Ombudsman (PPO) if you are not happy with the outcome of your complaint.

You can only contact the PPO after you have been through the prison’s appeal process. You have to contact the PPO within 3 months of your appeal. The PPO is independent from the Prison Service and can look into complaints.

To complain to the PPO, you should tell them why you are unhappy with the prison’s response. If you have any paperwork from the prison's complaint process, you should send this too. These are the PPO’s contact details.

Prisons and Probation Ombudsman

An independent body that investigates complaints about prisons.

Telephone: 020 7633 4149 or 0845 010 7938 Address: PO Box 70769 London SE1P 4XY
Write ‘Confidential Access’ on the envelope and seal it if you don’t want prison staff to read your letter.

The PPO will contact you within 10 days to tell you if they will investigate your complaint or not. If not, they should tell you why. You will get an investigator if the PPO decides to look into your case. They will try to settle your complaint using the following stages:

  • Local resolution – trying to find an answer that you and the prison are happy with. This is the quickest way of trying to resolve your complaint.
  • Report or letter – the PPO does this if you and the prison do not agree. It is also a quick way of trying to resolve your complaint.
  • Full investigation – this will happen if you and the prison cannot agree. It is more detailed than the report or letter stage and takes longer. The investigator will gather information and say whether or not they think the PPO agrees with your complaint. If they do not agree, they should explain why. If they agree, they might make recommendations to the prison. This is to make sure the same thing does not happen again.

The PPO should look at your complaint within 12 weeks.

You can write back to the PPO if you disagree with their decision. You might think that the PPO does not understand your complaint or think that they have missed something important. The PPO can reopen your complaint and do more work on it if they agree with you. The PPO will write to you with an explanation if they do not change their decision.

What can I do if I still disagree with the PPO’s decision?

You can complain to the Parliamentary and Health Service Ombudsman (PHSO) if you are unhappy with the PPO’s decision. To complain to the PHSO you need to fill out their complaints form. You can find this on their website. You then need to pass this on to your local MP.

To find out who your local MP is, go to the website here or contact the House of Commons Information Line on 020 7219 4272.

How can I complain about a relatives experience?

You can help your relative or friend complain about problems they have had in prison. You can help them by finding out about the complaints process and the local contact details. You could help to put the complaint together.

Your relative or friend should agree in writing that they are happy for you to complain for them. If they don’t do this then the prison may not accept your complaint.

If your relative cannot read or write, then you can write out a letter for them. You can ask them to put an X in a box next to a sentence saying they are happy for you to complain for them. Your relative can then put their initials on the complaint form. You will need someone to be a witness for this such as a friend or family member.
