Booking a visit

How to book

• Online: book through the official page (the quickest way for most people).
• By phone: 01747 856 586 .

If they are on remand you can usually book straight away. If they are convicted, they must send you a visiting order first. Children can visit, and many prisons run relaxed family days: see children and prison.

What to expect at the gate

• Every visitor aged 16 or over must prove who they are. Check the list of accepted ID before you go.
• Everyone gets a pat-down search, including children, and a sniffer dog may check you.
• You must follow the prison's dress code (no ripped clothing, nothing too revealing, no hoods up).
• You can take in very little. Leave most things in a locker or your car, usually including pushchairs and car seats. Bring coins for the locker and the café.

There is a visitors' centre . It is a good place to wait and ask questions.

Phone calls

They ring you, from approved numbers only, and they pay for the call. Your number has to be submitted and checked first, which takes days: see why numbers take time to approve. Once calls are flowing, most families can cut the cost sharply: check the call cost calculator and the cheaper calls guide.

Sending money and things in

Money goes through the free official service, Send money to someone in prison. You need their prisoner number and date of birth. There is a weekly cap on what they can spend: see how much is worth sending. For letters, photos, clothes and books, read what you can send in, then check Guys Marsh Prison's own rules on the official page before posting anything.

What inspectors found at Guys Marsh Prison

Independent inspectors visit every prison, test it against four standards, and publish what they find. This is from the most recent full inspection of Guys Marsh Prison, in April 2025:

From the full HM Inspectorate of Prisons report, where each standard is scored from poor up to good. Contains public sector information licensed under the Open Government Licence v3.0. Things can change quickly after an inspection, for better and worse.

Every prison also has an Independent Monitoring Board: ordinary people who go in regularly and publish a yearly report on daily life inside. Worth a read if you want more detail.

If money is tight

On a low income, the Assisted Prison Visits Scheme can pay your travel to Guys Marsh Prison, and hardly anyone claims it: check if you qualify.

Contacts and complaints

Contact Guys Marsh Prison

Worried about someone right now

If you fear for a prisoner's safety, ring the prison on 01747 856 400 and ask for the Safer Custody team or the orderly officer, and say it is an emergency. For urgent family news like a death or serious illness, ask for the chaplaincy. The free Prisoners' Families Helpline (0808 808 2003) can help you reach the right person.

Making a complaint about the prison

As a family member you cannot use the prisoner's internal complaints system, but you can raise concerns. Contact the prison first (01747 856 400) and keep a note of who you spoke to. If it is not sorted out, these are independent of the prison:

• The Independent Monitoring Board (IMB) for Guys Marsh Prison: unpaid volunteers who go into the prison regularly and can look into concerns. Find its contact details through imb.org.uk.
• Your local MP, who can raise matters with the prison and the Ministry of Justice on your behalf.
• The Prisons and Probation Ombudsman (PPO) investigates every death in custody, and complaints from prisoners once they have finished the internal process. If someone has died in custody, contact the PPO directly.

The official steps are set out on GOV.UK: making a complaint about a prison.

How the prisoner makes a complaint

The person inside asks a member of staff for a complaint form (often called a "COMP 1") and can put in a complaint about almost anything. If they are unhappy with the answer, they can escalate it, and then write confidentially to the Prisons and Probation Ombudsman. They also have confidential access to the Independent Monitoring Board and to their own MP, which staff cannot read or block. Serious safety issues can go straight to Safer Custody.
