How to book a secure video call
Secure video calls at this prison can be requested by prisoners only.

Phone calls
Prisoners do not have phones in their cells so they will always have 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.
They can make calls between 8:15am and 7:10pm Monday to Friday and between 8:15am and 5:10pm on weekends.
You can also exchange voicemails using the Prison Voicemail service.

Send money and gifts
You can use the free and fast online service to send money to someone in prison.
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
Friends and family can send books to prisoners. Make sure to include the person’s name and prisoner number on the parcel. They will be opened and checked by officers.
It’s not possible to send any other items or property. You can send prisoners money instead which they can use to buy items through a catalogue system.
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.
For the full list of approved retailers, you can read the HMPPS Incentives Policy, Annex F.
