Monthly and annual savings, including BluePhone subscription cost
Rates charged from the prisoner's credit account per minute
| Number type | Weekday | Weekend | Saving vs mobile |
|---|---|---|---|
| UK mobile (07…) | 5.5p/min | 3.6p/min | — |
| UK landline (01…/02…) | 2.48p/min | 2.2p/min | 55% cheaper |
A minimum charge of 10p applies per call. Rates are set by HMPPS and apply across all ITS-connected prisons in England and Wales.
The difference between a mobile call and a landline call from prison isn't just a few pence per minute — it's the difference between your loved one being able to call every day or running out of credit by Thursday. When you multiply the rate difference across weeks and months, the numbers become significant.
HMPPS sets these rates nationally for England and Wales. The landline rate has always been lower than the mobile rate because the underlying call termination costs differ. BluePhone provides a real UK landline number (01/02 prefix), which you give to your loved one to add to their prison phone list so they can call at the cheaper rate.
The calculator uses 4.33 weeks per month. Mixed means 50% weekday and 50% weekend calls of equal duration. Extra minutes assume the same number of calls with longer conversations; prison limits still apply. Weekend calls are charged at lower rates (3.6p mobile, 2.2p landline), so if your loved one calls mainly at weekends, your actual savings will be proportionally smaller — though the landline is still cheaper either way.
At weekday rates, the £15 monthly subscription is offset at roughly 497 minutes per month, before minimum charges and rounding. Shorter or mainly weekend calls change this threshold.
Even at lower call volumes, BluePhone provides value beyond the raw numbers: you can be anywhere in the world and still receive calls, your loved one doesn't need to spend their limited credit calling international rates, and the call reaches you reliably on your smartphone just like any other call.
The money saved in call credit stays in your loved one's prison phone account — meaning more minutes to talk. If they're currently calling at 5.5p/minute and switch to 2.48p/minute, the same credit amount buys them more than twice as many minutes. At weekday per-minute rates, £11 buys 200 mobile minutes or about 443 fixed-line minutes: about 243 extra minutes, before minimum charges and rounding.
Alternatively, the prisoner can spread their calls more evenly through the week, or family members on a tight budget spend less on credit top-ups while maintaining the same amount of contact.
The rates above are the HMPPS 2025 national rates for ITS (Unilink) connected prisons in England and Wales. They apply to the vast majority of UK prisons. A small number of private prisons may vary slightly. Scotland and Northern Ireland operate separate systems.
The minimum is applied per call: use the greater of 10p or minutes multiplied by the rate. It is not a 10p surcharge. The calculator applies this minimum to each call.
BluePhone charges a flat monthly subscription (£15/month or £149/year). There are no per-call or per-minute charges on the BluePhone side. The call credit cost shown in the calculator is what comes out of your loved one's prison phone account — that's what you're saving by switching them to a landline number.
Yes. Your BluePhone landline number can be added to any number of prison phone lists across different prisons. Multiple people can call the same number — though only one call at a time will connect. This is useful if you have more than one loved one in prison.
