What is the Great British Switch off? and how can you make sure you're ready?

What is the Great British Switch Off?

We’re all familiar with the copper telephone network - also known as the PSTN (Public Switched Telephone Network).

But in 2017, BT announced that it was coming to end of life, and plans were made to switch it off.


Come December 2025 the copper network will cease to exist, and everyone using PSTN based voice or broadband services will need to move.


What is the Alternative? 

Over the next few years, consumers will be urged to move any PSTN based broadband (ADSL/FTTC) to full fibre alternatives (SOGEA, FTTP or Leased Line).

Anyone using PSTN based voice services (also known as, traditional phone lines) will be asked to migrate to VoIP (Voice over Internet Protocol), a solution that transmits voice calls using an internet connection.
