The Big Switch OffIs Coming January 2027.
BT Openreach is permanently switching off the UK's copper phone network. Every business using analogue lines, ISDN, or legacy devices must upgrade before the deadline — or go offline.
What is the Big Switch Off?
The end of copper-based telephony and the transition to modern digital communications.
The Big Switch Off refers to BT Openreach's plan to retire the UK's ageing Public Switched Telephone Network (PSTN) and ISDN infrastructure by January 2027.
These copper-based analogue lines have powered the UK's phone network for decades, but they're being permanently switched off and replaced with modern, fully digital infrastructure.
Every business and household in the UK that still uses an analogue landline, ISDN phone system, or any device connected to the old copper network will need to upgrade before the deadline.
