The PSTN (Public Switched Telephone Network) switch-off in the UK and the stop sell in 2023 are major events in the telecommunications industry. The PSTN network has been in use in the UK for over 150 years and has been the backbone of the country’s communication infrastructure.

But with the introduction of new technologies such as voice over internet protocol (VoIP) and 4G/5G networks, it is no longer seen as a sustainable solution. The stop sell refers to the discontinuation of sales of PSTN-based devices and services, while the PSTN switchoff marks the end of the network’s use in the UK.

Ofcom, the UK’s communications regulator, and Openreach, a subsidiary of BT Group responsible for building and maintaining the UK’s communication infrastructure, are playing key roles in the transition to modern communication technologies. The decision to stop selling PSTN-based devices and services in 2023 has been made in order to encourage businesses and consumers to adopt more advanced and cost-effective technologies.

The timeline for the PSTN switchoff in the UK is as follows:

  • September 2023: Stop sell of PSTN-based devices and services.
  • December 2025: The target date for Openreach to switch-off the PSTN network

During this transition period, businesses and consumers will need to upgrade their communication systems to keep pace with the changes. This may cause some initial disruption, but it is expected to bring about significant benefits in the long run, including lower costs, improved call quality, increased flexibility, and reduced carbon emissions.

In conclusion, the PSTN switch-off and stop sell in September 2023 will mark the end of an era and the beginning of a more advanced and sustainable communication infrastructure in the UK. Ofcom and Openreach are playing key roles in this transition, working to ensure a smooth transition to modern communication technologies and meeting the changing needs of businesses and consumers.
