BT’s PSTN Shutdown Is Coming, Is Your Business Ready?

A Major Change to the UK’s Phone Infrastructure

BT has announced that the UK’s Public Switched Telephone Network (PSTN) will be fully shut down by January 2027. That means all traditional copper phone lines — the infrastructure that’s powered calls for over a century, will no longer function.

If your business is still relying on PSTN-based services, it’s time to act.

The switch-off affects not just voice calls but any system that uses analogue lines, including:

  • Alarm systems
  • Fax machines
  • Door entry systems
  • Payment terminals
  • Legacy broadband services

What You Need to Do

By 2025, new PSTN-based lines will no longer be sold, and by 2027, the entire network will be decommissioned. Businesses must migrate to digital-first alternatives now to avoid service interruptions.

That includes:

  • Moving to VoIP Phone Systems
  • Upgrading broadband to digital-ready fibre networks
  • Replacing PSTN-dependent infrastructure with cloud-connected alternatives

The Case for VoIP

Voice over Internet Protocol (VoIP) is the natural successor to PSTN. It runs entirely over broadband, with added benefits like:

  • Lower call costs
  • Remote access and mobile integration
  • Scalable call handling features
  • Easier setup and minimal hardware

For most businesses, upgrading to iPECS Cloud VoIP or another cloud-hosted system is the fastest way to future-proof their telecoms.

Not Just Phones, It’s About Your Entire Setup

PSTN often powers more than just phone lines. You might be surprised how many legacy systems still rely on copper, and what risks that creates if not addressed.
