You might have heard whispers, or perhaps even loud announcements, about the “Great Switch Off.” This isn’t just a technical upgrade; it’s a fundamental shift in how the UK’s communication network operates, and it will impact every business in the country.
What is the "Great Switch Off"?
Essentially, Openreach (who manage the UK’s primary telephone network) is retiring the Public Switched Telephone Network (PSTN) – the traditional copper phone lines that have powered our communications for decades. The final deadline for this complete switch-off is January 31, 2027.
This means that legacy services that rely on these copper lines – including traditional landline phone services (like WLR, ISDN2, and ISDN30), as well as many ADSL and FTTC broadband connections – will cease to function. They are being replaced by modern, internet-based “All-IP” solutions
Why is This Happening?
The PSTN is old technology, costly to maintain, and simply can’t keep up with the demands of modern businesses. The move to All-IP brings significant advantages:
- Faster, More Reliable Connectivity: New fibre-based solutions offer superior speeds and stability.
- Future-Proof Technology: Internet Protocol (IP) is the foundation of modern communication, ensuring your services are ready for future innovations.
- Enhanced Capabilities: All-IP opens the door to advanced voice and data services, improving business efficiency.
Key Dates Your Business Needs to Know:
- Nationwide Stop Sell (September 2023): This date has already passed. It means that you can no longer order new traditional copper-based services (like WLR) or make significant changes to existing ones in many areas. If your business needs a new line or service, you’ll be directed to All-IP alternatives.
- Exchange Switch Offs (Ongoing): Openreach is progressively turning off traditional services in exchanges across the country. Once an exchange hits 75% fibre availability, a “Stop Sell” is triggered for that area, and traditional services are eventually withdrawn. There’s a “no move back to copper” policy once a premises is covered by fibre.
- Final Deadline (January 31, 2027): By this date, all traditional PSTN services will be permanently switched off.
The Great Switch Off Timeline
How Does This Affect Your Business?
The switch-off isn’t just about your phone line; it impacts a wide range of services:
- Business Phone Lines: If you use traditional analogue lines or ISDN for your voice calls, these will need to be migrated to VoIP (Voice over Internet Protocol) solutions.
- Broadband: Many ADSL and FTTC broadband services rely on the copper line. These will need to transition to “Single Order” broadband solutions like SOGEA, SOADSL, or FTTP.
- Specialised Equipment: This is crucial! Services often connected to traditional phone lines include:
- Alarm Systems: Fire, intruder, and personal alarms (including Telecare).
- Payment Terminals (PDQs): Card machines used for transactions.
- CCTV: Older systems relying on analogue lines.
- Lift Lines: Emergency phones in lifts.
- Gate Entry Systems
If these devices are not migrated, they will simply stop working after the switch-off, potentially causing significant disruption and even safety issues for your business

- SOADSL (Single Order Asymmetric Digital Subscriber Line): For areas not yet covered by fibre, this replaces traditional ADSL, offering speeds up to 24Mbps.
- Modern Voice Solutions:
- Microsoft Teams Voice: Integrate your phone system directly into Microsoft Teams for seamless communication, collaboration, and calling from virtually anywhere.
- Zoom Phone: Extend Zoom’s familiar collaboration platform with enterprise-grade phone capabilities, offering flexibility and advanced features.

What You Need to Do NOW:
Delaying action could leave your business vulnerable to service disruption. Here’s your checklist:
- Audit Your Services: Identify every service in your business that uses a traditional phone line or older broadband connection. Don’t forget alarms, payment terminals, faxes, lift lines, and any other connected devices.
- Understand Your Needs: For each service, determine if it can be migrated to an All-IP solution. Consider your future needs – do you need more speed, more features, or simply a reliable replacement?
- Plan Your Migration: Don’t wait until the last minute! Migrating services, especially for complex setups, takes time.
- Communicate Clearly: Ensure all stakeholders within your business are aware of the changes and the timeline.
