2027 PSTN Switch off - What you need to know

With the eventual end of the Public Switch Telephone Network (PSTN) you may be left questioning what will happen.

By January 31st 2027, the Public Switch Telephone Network (PSTN) and Integrated Services Digital Network (ISDN) that has powered the UK for over a century will be retired. This will affect landline and phone options that are still connected to these networks.

Why is this happening?

Outdated Infrastructure: The copper network is over 100 years old. It is increasingly difficult and expensive to maintain, with spare parts becoming non-existent.

The Demand for Speed: Modern businesses require the bandwidth that only a fully digital, fiber-based network can provide.

Global Alignment: The UK is following a global trend. Countries like Germany, Japan, and the USA have already completed or are well into their digital migrations.

 

Why modernise now?

The Risk Of Inaction

  • Total service loss after the 2027 cut-off.
  • Rising costs for maintaining obsolete copper lines.
  • Fragile hardware that is no longer being manufactured.

The Digital Advantage

  • Reduced Monthly line rental and call costs
  • High-definition voice quality and instant scalability
  • Built-in features: Virtual Landlines, Auto-Attendants and Apps.
