Planning Your School’s Transition Away from PSTN and ISDN Before January 2027
With the UK’s traditional phone network scheduled to be withdrawn by January 2027, schools and Multi Academy Trusts (MATs) must plan the transition away from PSTN and ISDN services.
This change goes beyond replacing desk phones. Connected equipment may still rely on analogue phone lines, meaning the withdrawal can impact emergency communications, alarms, connectivity, and day to day school operations if not planned carefully.
Managing the transition across a school or trust can feel complex. However, with early planning, phased migration, and the right support, it can be delivered smoothly. To help, we’ve created a free BT Switch Off support guide, designed specifically for education settings.
BT Switch Off Transition Guide
This guide provides schools and MATs with practical tools and expert guidance to help plan and manage the move away from analogue phone services in a controlled, low-disruption way.
- Plan the transition early and avoid last-minute disruption
- Maintain reliable communications and safeguarding systems
- Ensure services remain supported beyond the 2027 deadline.
Guide Contents
The guide covers the key areas schools and MATs need to consider for a smooth transition, including:
- Understanding what the BT Switch Off means
- Identifying phone lines and connected services that rely on PSTN or ISDN
- Reviewing broadband and network readiness for digital voice services
- Planning a phased migration aligned with the school calendar
