2027 MIGRATION GUIDE

Plan the move.
Keep business moving.

The UK PSTN retirement is scheduled for 31 January 2027. Check what depends on your current phone service before changing it.

What to check before migrating

01

Identify your phone lines

Check for analogue voice lines, ISDN services, fax and older telephone systems. Ask your current provider which services are affected.

02

Check connected equipment

Alarms, lift emergency phones, payment terminals, door-entry systems and telecare equipment may use analogue connectivity. Speak to each equipment supplier about compatible replacements.

03

Review connectivity and power

Digital calling usually relies on working connectivity and powered equipment. Plan for outages, including any critical calling needs and emergency calls.

04

Arrange numbers and migration

Confirm number-porting eligibility, lead times, installation, testing and any interim call forwarding before cancelling an old service.

Important distinction

The PSTN switch-off does not mean all copper broadband disappears on 31 January 2027. Broadband upgrades and local network changes are separate programmes.
