Your Business Phone Lines Are Being Switched Off.
The UK's traditional PSTN and ISDN phone network is being permanently decommissioned in January 2027. Every business still relying on copper lines must migrate -- or go dark. VEHDA makes the transition seamless.
Time remaining until switch-off
What's Happening?
The End of Traditional Phone Lines -- Explained Simply
For decades, UK businesses have relied on the PSTN (Public Switched Telephone Network) -- the copper-wire infrastructure that carries traditional phone calls. Openreach has confirmed this entire network will be permanently switched off in January 2027. Every PSTN and ISDN connection in the UK will stop working.
Key Milestones
2015 -- Announcement
Openreach announces PSTN retirement
BT Openreach confirms plans to decommission the legacy copper network across the UK.
2023 -- Stop sell
New PSTN/ISDN lines can no longer be ordered
Openreach stops selling new copper connections. Migration to IP becomes the only path forward.
Now -- Act
Time to migrate is running out
Engineer capacity is filling up. Businesses migrating now avoid rushed timelines and post-deadline disruption.
January 2027 -- Deadline
Full PSTN switch-off
All remaining PSTN and ISDN connections are permanently deactivated.
Who Is Affected?
Traditional business phone lines
Any line provided over copper -- BT landlines, ISDN2, ISDN30
PDQ and payment terminals
Card machines connected via traditional landlines need reconfiguring or replacing
Alarms and security systems
Many alarm diallers and monitoring connections rely on PSTN
Legacy PBX phone systems
On-premise PBX systems connected via ISDN trunks will need to migrate to SIP or hosted
ADSL/FTTC broadband
Broadband that runs on a copper phone line will need to switch to SOGEA or FTTP
