By January 2027, the UK's analogue telephone network will be switched off.
This affects more than just telephone lines.
Lift emergency call buttons, Emergency Call Systems, door entry and fire alarms may be built around analogue communication systems.
Ask your property manager to start checking now whether any of the systems in your building rely on analogue phone lines.
There is time to ask each of your contractors (e.g. lift contractor, fire alarm contractor) to advise on suitable alternative digital provision before the analogue phone lines are switched off in January 2027.
These don't necessarily need to be expensive. For example, lift emergey call button might be able to alternatively provided via a mobile GSM sim card, fitted by your lift contractors on their next visit.
