About LineKeeper

This is the official website of the LineKeeper™ Hub Battery Backup.

As the UK switches every home from copper to digital phone lines, the landline stops working when the power goes off. For many people, especially older relatives with pendant alarms, that's the moment they need it most.

We built LineKeeper to close that gap: a small, silent battery that anyone can fit behind the telly in 60 seconds, which keeps the hub, phone and Wi-Fi going for hours rather than minutes.
