The clock is no longer just ticking its racing. On 31 January 2027, the UK’s old PSTN telephone network will be switched off for good, and there are only six months left to prepare. If your business is still relying on legacy phone lines, this is not a “someday” problem. It’s a “right now” problem.
The Numbers Don’t Lie
Openreach’s James Lilley, Director of Customer Migrations, has issued a stark reminder: while millions of customers have already migrated to digital services, around 1.5 million lines are still stuck on the old network — many of them businesses still running on outdated infrastructure. If your organisation is one of them, every week you wait narrows your window to migrate safely and affordably.
Why This Can’t Wait
When the PSTN switches off, anything still connected to it — phone lines, alarm systems, payment terminals, fax machines, lift lines — could simply stop working. No warning call. No grace period. Businesses that leave migration to the last-minute risk service outages, scrambled last-minute upgrades, and paying a premium for rushed installations. Six months sounds like a long time. It isn’t, once you factor in planning, ordering, installation, and testing.
Your Immediate Action Checklist
✅ Review every service connected to your phone lines
✅ Understand exactly what’s affected by the switch-off
✅ Put a migration plan in place — today, not next quarter
