What you'll need
- A rough idea of what is connected to your phone line or broadband (alarms, door entry, payment terminals, etc.)
- If you are not sure, that is fine. The checker has a "don't know" option for every question.

Am I affected by the landline switch?
The UK is switching off the old analogue phone network by January 2027. If you have any device that connects through the phone line or broadband, it could be affected. This includes telecare pendants, burglar and fire alarms, door entry systems, lift emergency phones, card payment terminals, fax machines, and franking machines.
Most people know about the phone itself, but miss the devices that dial out silently in the background. An alarm communicator, for example, uses the phone line to alert a monitoring centre. If the line changes and the communicator is not updated, the alert may never get through.
The device checker asks about your setup and tells you which devices are at risk. It takes about two minutes and does not require any account or personal details. You get a printable report with specific next steps for each device.
How it works
We ask about the devices connected to your phone line or broadband. For each one, we check whether it might be affected by the change from the old analogue phone network to digital voice.
You get a risk rating for each device (low, check, high, or urgent) with specific next steps. You can print the results.
This is general guidance, not a compatibility certificate. For confirmation, you will need to contact your phone provider and any device supplier or monitoring company.
