How does the PSTN switch-off affect your business?
The UK’s traditional Public Switched Telephone Network (PSTN) is being permanently withdrawn, with all analogue copper phone lines due to be switched off on 31st January 2027.
This means every business still relying on PSTN or ISDN services will need to migrate to digital voice (VoIP) or all‑IP alternatives before the shutdown. Tens of thousands of organisations across the UK still operate on fax machines, card machines, alarms, lift lines, building systems, and telephony that depend on legacy copper-based lines.
Final switch-off of PSTN across the UK, completing the transition to a fully digital phone network.
If your business is in South Wales and still relies on landline technology, you’re at risk of:
The PSTN switch‑off affects both voice and broadband services that rely on copper lines, including ADSL and FTTC. As these services are withdrawn, it’s essential to understand how your current setup will be impacted.

You’ll receive a clear breakdown of what needs upgrading, what risks exist, and the best route to move your business onto secure all‑IP and fibre‑based solutions.
