Isis is a men’s prison and young offender institution (YOI) in Thamesmead, South East London. It is named Isis after the ancient name for the River Thames.
For all visits, at least one visitor must be 18 or older. Up to 3 adults and 3 children can visit, but spaces are limited so numbers may need to be restricted. Each visiting application is dealt with on a case by case. You will be informed if we are unable to accommodate the number of visitors in your group for your chosen visit session.
There may be a limit to the number of visits a prisoner can have. You can check this with Isis prison.
All visitors will need to be given a pat-down search, including children. You may also be sniffed by security dogs.

There are strict controls on what you can take into Isis. You will have to leave most of the things you have with you in a locker or with security. This includes pushchairs and car seats.
You will be told the rules by an officer at the start of your visit. If you break the rules, your visit could be cancelled and you could be banned from visiting again.
Visiting facilities
There is a visitors centre run by the Prison Advice and Care Trust (PACT) charity. Full visiting facilities are now available including the serving of refreshments during social visits and a children’s play area.
We aim to provide four family days a year: Easter, Summer Holidays, October half-term and Christmas holidays.
These will be divided by one family visit per residential unit.
Keep in touch with someone at Isis
There are several ways you can keep in touch with someone during their time at Isis.
Phone calls
Prisoners have phones in their cells so they are able to call you. They have to buy phone credits to do this.
They can phone anyone named on their list of friends and family. This list is checked by security when they first arrive so it may take a few days before they are able to call.
You can no longer send money by bank transfer, cheque, postal order or send cash by post.
If you cannot use the online service, you may be able to apply for an exemption - for example if you:
are unable to use a computer, a smart phone or the internet
do not have a debit card
This will allow you to send money by post.
Gifts and parcels
People in Isis are given a list of approved items that can be sent to them as gifts. Contact Isis for more information on what’s allowed.
In the first 28 days, prisoners can apply to get a clothing parcel handed in. They can apply for another after 6 months. Parcels can be handed in at visits.
Make sure to include the person’s name and prisoner number on the parcel.
All parcels will be opened and checked by officers.
Friends and families of prisoners are permitted to send books directly to their loved ones, or can order books from approved retailers, which can source and send the books on to prisoners.
When someone first arrives at Isis, they will be able to contact a family member by phone. This could be quite late in the evening, depending on the time they arrive.
They will get to speak to someone who will check how they’re feeling and ask about any immediate health and wellbeing needs.
Induction
Each prisoner who arrives at Isis gets an induction that lasts about 2 weeks. They will meet professionals who will help them with:
health and wellbeing, including mental and sexual health
any substance misuse issues, including drugs and alcohol
personal development in custody and on release, including skills, education and training
other support (sometimes called ‘interventions’), such as managing difficult emotions
Everyone also finds out about the rules, fire safety and how things like calls, biometric application kiosks and visits work.
Accommodation
Around 600 prisoners live at Isis in 2 house blocks called Thames and Meridian. There is a mixture of single and double cells.
Facilities include a gym, education and vocational training centre, segregation unit and fitness academy.
Education and work
Prisoners have access to education and training provided by Novus.
They can get academic qualifications, as well as certificates in a broad range of work-related subjects, including:
Prisoners also have the opportunity to apply for jobs in almost all aspects of prison life.
Those who do a learning and development qualification can apply for jobs as mentors and peer group workers.
Family support in the visitor centres, family days, family group work
and one to one case work around family issues is all provided by the Prison Advice and Care Trust (PACT).
Specialist staff and voluntary workers make sure that friends and families get a warm welcome. They offer emotional support and practical information about prison life and procedures.
Extra individual support and information packs can be given to first time visitors.
Family group work is offered which focuses on how fathers can build and maintain healthy relationships with their families while in prison. They help prisoners to set realistic goals for family life, to consider the practical and emotional impact on themselves and their families and how to deal with them.
Oxleas also provides family-focused sessions about issues such as drug and alcohol abuse and addiction, wellbeing, relationships, communication, resilience and family group conferencing.
It can also refer family members on to relevant services they may find useful.
