Openreach confirms UK landline PSTN network switch-off on 31 January 2027, with no extension

Openreach has written to communications providers confirming the PSTN switch-off on 31 January 2027, with no postponement, after an earlier deadline was pushed back at government request to protect vulnerable users of TeleCare. Affected systems include POS terminals, fire and intruder alarms and personal care alarms. Non-fibre lines will likely move to SOTAP for Analog, which keeps legacy lines working via equipment in the local exchange. Defenders should audit remaining analogue dependencies, especially complex business connections, and plan migrations with their provider early. Rental charges for legacy business lines have doubled year on year.
