Understanding the PSTN Switch Off
The PSTN switch-off marks a significant shift in the UK’s telecommunications landscape, affecting businesses and individuals alike. Understanding the key aspects of this transition, including what the PSTN is, why it’s being phased out, and the crucial dates to keep in mind, is essential for ensuring a smooth transition to modern communication systems.
What Does PSTN Stand For?
The PSTN switch-off refers to the planned discontinuation of the Public Switched Telephone Network (PSTN) in the UK. This legacy system, which has been in use for over a century, will be replaced by digital communication technologies like Voice over Internet Protocol (VoIP) by the end of 2025. The switch-off means that all traditional landline phone services will be phased out, requiring users to migrate to internet-based services.
What is a PSTN Line?
A PSTN line is a standard telephone line that uses the Public Switched Telephone Network to transmit voice calls. These lines rely on copper cables and circuit-switched technology to establish and maintain connections. PSTN lines have traditionally been used for both voice communication and certain types of data transmission, such as fax and dial-up internet services. However, as the network is phased out, these lines will be replaced by digital alternatives like VoIP.
Why is the PSTN Being Switched Off?
The PSTN is being switched off because it is an outdated technology that is becoming increasingly difficult and costly to maintain. As telecommunications move towards digital solutions, the demand for traditional landline services has declined. Modern digital networks, such as VoIP, offer greater flexibility, better call quality, and the ability to integrate with other internet-based services. The shift to a fully digital network will also support the UK's broader goal of establishing a more robust and future-proof communication infrastructure.
Key Dates You Need to Know
Key dates surrounding the PSTN switch-off are critical for planning your transition to digital communication. The initial stop-sell date has already passed in September 2023, meaning no new PSTN services can be ordered. By December 2025, the switch-off is set to be complete, with all services migrating to digital networks. Recently, a delay has been announced, pushing the final switch-off to January 2027, giving businesses and individuals more time to prepare.
PSTN Switch Off Dates (2025, 2027)
- September 2023: Stop-sell of new PSTN services begins.
- December 2025: Original date for the PSTN switch-off.

Is the PSTN Switch Off Being Extended or Delayed?
Yes, the PSTN switch-off has been delayed from its original 2025 date to January 2027. This delay was introduced to ensure that vulnerable populations and businesses have adequate time to transition to digital services. The extension aims to minimise disruptions and allow for more comprehensive preparations.
What Does the PSTN Switch Off Mean for the UK?
The PSTN switch-off means that the entire UK will transition to a fully digital communication infrastructure. This shift will modernise the country’s telecommunications network, leading to improved service reliability, better integration with digital tools, and the potential for more advanced features. However, it also means that businesses and individuals must upgrade their existing systems to continue receiving uninterrupted services.
Regulatory Perspective: gov.uk and Ofcom's Role
The UK government and Ofcom, the communications regulator, are overseeing the PSTN switch-off to ensure a smooth transition. Ofcom has set guidelines and timelines for the switch-off, while also monitoring the rollout to ensure that all stakeholders are informed and prepared. The government is working closely with telecom providers to address challenges, particularly for vulnerable groups, to ensure that no one is left behind during this significant change.

How the PSTN Switch Off Will Affect You?
The PSTN switch-off will have significant implications for businesses and residential users alike. Understanding the impact on your communication systems, equipment, and phone numbers is crucial for preparing and ensuring a smooth transition to digital alternatives.
Impact on Your Business Communication
The PSTN switch-off will fundamentally change how businesses communicate. Traditional landline services, which rely on the PSTN, will be phased out, requiring businesses to shift to internet-based communication systems like VoIP. This transition may offer benefits like improved call quality and cost efficiency, but it will also necessitate changes in infrastructure and operations. Businesses will need to assess their current systems and plan for the migration to ensure uninterrupted communication with clients and partners.
What Changes Do You Need to Make?
To prepare for the PSTN switch-off, businesses need to transition from traditional landline services to digital alternatives such as VoIP or
