The PSTN Network in the UK will be Shutting Off in 2025

The PSTN Network in the UK will be Shutting Off in 2025

The UK's analogue Public Switched Telephone Network (PSTN) is being replaced with a fully digital network by 2025. This transition is already underway and will continue until the complete shut off of the PSTN.


This article provides a timeline of events leading up to the shut off, explains how it will affect everyone, why it's happening, and what solutions you can move to.  If you are looking for advice or support during this transition then you are in the right place. Your Comms Group can help you make the move that makes sense to your business.


Timeline of Events:


  • In 2017, BT announced its intentions to shut off the PSTN and ISDN networks by 2025.
  • In 2018, Openreach began improving its networks with fibre to make high-quality connectivity more accessible.
  • In 2020, a five-year reminder was issued that Wholesale Line Rental (WLR) would be withdrawn.
  • In 2023, the stop-sell of all WLR lines will take place.
  • By 2025, Openreach will complete the shut off of all PSTN and ISDN services.




How Will This Affect Everyone?


The transition to digital is happening everywhere and is happening fast. All lines will eventually transition to a fully digital environment. Non-voice services connected to PSTN or ISDN lines, such as alarms, EPOS machines, broadband, CCTV, door entry systems, and even faxes, will also be affected.


Why Is This Happening?


Technology is changing faster than ever, and as our lives become more digital, the connectivity we use to support it must become stronger too. The PSTN network has been the backbone of the UK's network for a long time, but it's time to move on to more reliable digital communication.




Is This the Right Step for Us?


Moving to digital is about better and more reliable digital communication across the globe. It allows for basic things like making and taking calls on any device, from anywhere in the world. It also allows for linking business applications and systems with video chat, calls, and collaborations, making you closer to your colleagues and customers. Finally, it reduces costs by taking you away from expensive hardware.
