Is your business ready for the PSTN Switch-Off?

The UK's Public Switched Telephone Network — the copper-wire system behind every traditional landline — is being permanently switched off by Openreach on 31 January 2027. It isn't only phone handsets: fax machines, some alarm systems and PSTN-connected door entry systems will stop working once the copper network is retired, and ADSL/FTTC broadband bundled with a landline is affected too.

• Traditional analogue and ISDN phone lines will stop working after the deadline
• Broadband sold bundled with a landline (ADSL/FTTC) is affected — full fibre, cable and mobile broadband are not
• Older alarm systems and door entry systems that dial out over a phone line need checking
• The main replacement for business telephony is VoIP, running over your internet connection
• Openreach now needs as little as 90 days' notice before disconnecting an individual line
