The PSTN Switch-Off

Is Your Business Ready for 2027?

The UK’s Analogue Phone Network Is Closing

By January 2027, the UK’s Public Switched Telephone Network (PSTN) will be permanently switched off. This includes ISDN lines too.

If your business still uses landlines or any equipment that relies on analogue lines, you’ll need to take action before the switch.

What Is the PSTN?

PSTN is the old copper phone network that has been used for decades. It’s being phased out in favour of modern, internet-based services such as VoIP and fibre broadband.

What Could Be Affected?

You may be impacted if you still use:

  • Traditional desk phones (non-VoIP)

  • Alarm systems

  • Card machines or EPOS systems

  • Door entry or lift phones

  • Fax machines

  • ADSL broadband

What You Can Do

Switch to VoIP

Internet-based phone systems offer better call quality, lower costs, and work from any location.

Check Your Broadband

Some businesses may need to upgrade to full fibre to support digital systems.

Audit Your Devices

Identify which services are still on analogue lines. This could include systems you don’t often think about (like lift phones or alarms).

Why Plan Ahead?

Although 2027 feels far away, services are already being withdrawn in many areas. Waiting could mean:

  • Disrupted services

  • Delays due to engineer shortages

  • Costly last-minute upgrades
