Keep in touch with someone at Isis

There are several ways you can keep in touch with a resident during their time at Isis.

Phone calls

Residents have phones in their rooms 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 also exchange voicemails using the Prison Voicemail service.

Officers may listen to phone calls as a way of preventing crime and helping keep people safe.


You can send emails to someone in Isis using the Email a Prisoner service.

You might also be able to attach photos and receive replies from the resident, depending on the rules at Isis.


You can write at any time.

Include the person’s name and prisoner number on the envelope.

If you do not know their prisoner number, contact Isis.

All post, apart from legal letters, will be opened and checked by officers.

Send money and gifts

You can use the free and fast online service to send money to someone in prison.

You can also send:

  • postal orders
  • cheques
  • cash

Postal orders and cheques should be made payable to ‘NOMS Agency’ or ‘HMPPS’ and include the resident’s name and prisoner number on the back.

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, men can apply to get a clothing parcel handed in. They can apply for another after 6 months. Parcels can be handed in at visits.

Arrival and first night

When a resident 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.

  • 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.

Support at Isis

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 men 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.
