The Big PSTN Switch-Off – What It Means for Your Business

The UK telecoms landscape is undergoing one of the biggest changes in decades. The planned switch-off of the Public Switched Telephone Network (PSTN) by BT Group is fast approaching, with all traditional landlines set to be retired by 2027.

So, what does this actually mean?

In simple terms, analogue phone lines will no longer work. Everything will move to digital, meaning calls will be made over the internet using VoIP (Voice over Internet Protocol).

Why is this happening?

The current infrastructure is outdated, expensive to maintain, and no longer fit for modern communication needs. Businesses now rely on flexible, scalable systems, and that’s exactly what digital solutions provide.

What should businesses be doing now?

If you’re still using traditional phone lines, now is the time to act. Waiting until the deadline could leave you exposed to disruption.

Key steps include:

• Reviewing your current telecoms setup

• Identifying any systems that rely on analogue lines (alarms, lifts, payment terminals)

• Moving to a cloud-based phone system

The opportunity

While change can feel disruptive, this is also an opportunity to upgrade. Modern systems offer:

• Remote working capabilities

• Call analytics and reporting

• Seamless integration with CRMs
