By December 2027, BT Openreach will permanently switch off the UK’s traditional Public Switched Telephone Network (PSTN) and ISDN lines. This marks one of the biggest shifts in modern communications — and it will affect every business still relying on traditional phone systems.
The good news? There’s still time to prepare — and plenty of opportunity to benefit.
Why the Switch-Off Is Happening
The PSTN and ISDN networks were built decades ago. They’ve served the UK well, but as technology has advanced, these systems can no longer meet the demands of modern communication.
Maintaining copper-based networks is costly and inefficient. The future is fully digital — with all services running over Internet Protocol (IP) connections, offering clearer calls, better integration, and much greater flexibility.
By 2027, every business will need to have moved to digital alternatives such as VoIP (Voice over Internet Protocol) or hosted phone systems.
How It Will Impact Businesses
If your business still relies on traditional landlines, they will stop working once the switch-off is complete. This includes:
- PSTN and ISDN voice calls
- Fax machines and older alarm systems
- Payment terminals and other copper-based services
Businesses who act early will not only avoid disruption but also unlock major benefits: Lower running costs, improved flexibility, and modern communication tools that help teams work smarter.
