On 31 January 2027, the UK’s old PSTN telephone network will be switched off for good. That leaves just six months to prepare. If your business is still relying on legacy phone lines, this isn’t a “someday” problem — it’s a “right now” problem, as Jon Pentel has been highlighting on LinkedIn.
The Numbers Don’t Lie
Openreach’s Director of Customer Migrations, James Lilley, has issued a stark reminder: while millions of customers have already moved to digital services, around 1.5 million lines are still stuck on the old network — many of them businesses running on outdated infrastructure. If yours 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 outages, rushed upgrades, and premium prices for emergency installations. Six months sounds like plenty of time. It isn’t, once you factor in planning, ordering, installation, and testing.

We’ve already helped countless businesses migrate ahead of the deadline. We can do the same for you — but only if you act now.
Don’t Wait Until It’s Too Late
Six months will disappear faster than you think. Businesses that migrate early avoid the chaos; those that wait will be fighting for installer availability in the final weeks before switch-off.
