PSTN Switch-Off Explained

The Public Switched Telephone Network (PSTN) is the UK’s traditional copper-based phone system. It has been in service for more than 40 years and supports landlines, old-style broadband, alarms and many business-critical systems.

The PSTN is outdated, expensive to maintain, and cannot support modern digital services. The UK is transitioning to full fibre and VoIP technology, offering faster, more reliable communication.

Stop-Sell: No new PSTN lines since 2023

Full Switch-Off: Scheduled for 2027

After this, all analogue services will cease to function.
