PSTN switch-off deadline: 31 January 2027
Your phone lines will stop working on 31 January 2027.
Openreach is switching off the UK’s traditional copper phone network, and there is no opt-out. If you still rely on a traditional line, your phones — and the alarms, card machines and lift lines connected to them — will stop working. Leave it too late and you risk losing service.
