Why Are UK Prison Calls So Expensive?

Many families are shocked when they first receive a phone bill after a loved one enters prison. What seems like a simple phone call can cost several pounds for just a short conversation. Over time, these costs can add up to hundreds or even thousands of pounds each year.

Understanding why prison calls are so expensive can help families make informed decisions, manage costs, and find more affordable ways to stay connected.

The Real Cost of Prison Phone Calls

Prison phone call charges vary depending on the prison telecom provider and the type of number being dialled. Calls to mobile phones are typically the most expensive.

In many UK prisons:
Calls to mobiles can cost up to 20–25p per minute
Calls to landlines are cheaper but still higher than standard rates
A 15-minute call may cost £3–£4
Regular contact can exceed £50–£100 per month

For families trying to maintain regular contact, these costs quickly become a financial burden.

Security and Monitoring Requirements

One of the main reasons prison calls cost more is the strict security infrastructure required. All calls must be recorded and monitored to ensure safety, prevent criminal activity, and protect victims. Maintaining secure monitoring systems, recording technology, and compliance processes adds significant operational costs that do not exist in standard consumer telecom services.

Specialist Prison Telecom Systems

Prisons do not use standard phone networks available to the public. Instead, they rely on specialised telecom providers that build and maintain secure systems designed specifically for custodial environments. These systems must integrate with prison security protocols, account management tools, and monitoring systems. The infrastructure is complex and costly to operate, which contributes to higher call charges.

Limited Competition Between Providers

Unlike consumer mobile or broadband markets, families cannot choose the telecom provider used by a prison. Contracts are typically awarded to specific providers, meaning there is little direct competition to drive down prices. Without consumer choice or market competition, pricing structures remain higher than standard telecom services.

Higher Costs for Mobile Call Routing

Calls to mobile phones are significantly more expensive than calls to landlines. This is due to additional routing charges and inter-network fees required to connect secure prison systems to mobile networks. As a result, families receiving calls on mobile phones often pay the highest rates.

Operational and Maintenance Costs

Prison phone systems must remain operational under strict security conditions and high usage demands. Equipment must be tamper-resistant, durable, and regularly maintained to prevent misuse. These operational requirements increase installation, maintenance, and staffing costs, which are reflected in call pricing.

The Best way to Reduce the Cost of Prison Calls

Although the cost structure cannot be changed, families can take steps to reduce expenses. Using a landline number instead of a mobile significantly lowers call rates. Scheduling call times can help avoid missed calls and wasted credit. One of the most effective solutions is using a virtual landline service. This allows prisoners to dial a landline number while the call is routed to your mobile, enabling you to receive calls at lower landline rates.This simple adjustment can dramatically reduce costs and make regular contact more affordable.

Prison calls are expensive due to security requirements, specialised telecom systems, limited provider competition, and higher mobile routing costs. While these safeguards are necessary, understanding how the system works can help families manage expenses and make communication more affordable. If you are searching for why prison calls are so expensive or how to reduce prison call costs, switching to a landline-rate solution can make a meaningful difference while ensuring you stay connected.
