The UK's ageing copper landline network is set to be switched off in January 2027, with new data revealing that more than 637,000 lines across ten major cities have yet to be converted to the new Digital Voice system.
Digital Voice, which uses fibre broadband instead of copper wires, offers enhanced features including better spam protection, clearer calls and the ability to forward incoming messages to smartphones. Firms such as BT have been warning consumers about the changes for several years, but millions have yet to make the switch.
Worst affected areas revealed
Using the latest data from BT's Openreach, the team at Phonely has created a league table of the worst areas for homes that remain on copper. London is the worst offender, likely due to the sheer number of people living in the capital. Leeds is second, followed by Manchester, Sheffield and Bristol.
Here is the full league table:
- London - lines remaining 235,934
- Leeds - lines remaining 62,411
- Manchester - lines remaining 55,961
- Sheffield - lines remaining 51,870
- Bristol - lines remaining 43,775
- Liverpool - lines remaining 42,351
- Edinburgh - lines remaining 39,132
- Cardiff - lines remaining 37,959
- Birmingham - lines remaining 37,825
- Glasgow - lines remaining 30,653
Advice for households
Bryn Thompson, Director at Phonely, said: “More than 637,000 lines still to be converted across just ten major city areas is a significant number, particularly with the January deadline getting closer.”
“For many households, the change can be relatively straightforward. It doesn't necessarily mean buying a new telephone or losing the phone number you've had for years.”
“We'd encourage people to check in with parents, older relatives or anyone they know who depends heavily on their home phone. This is particularly important if they use a personal alarm or other equipment connected to their phone line.”
“Our advice is not to panic, but don't ignore the change either. Speak to your current provider, find out whether your line has already been moved to digital and ask what you need to do if it hasn't.”
What is Digital Voice and how to prepare
Digital Voice is BT's next-generation home phone service, connecting homes via broadband technology. It offers modern features not found on old landline services, such as Multi Call, three-way calling for conference calls, and call diversion to any other phone number, including mobile phones. Call quality should also be much improved, though a compatible Digital Home phone is required. There is no extra charge for the service.
Phonely is urging homes to follow some simple rules, including checking whether phone services are already digital and making sure that current phones are compatible. It is also advisable to ask about keeping existing numbers, as most households can retain their current telephone number when moving to a digital service.
Another top tip is to check personal alarms and connected equipment. Telecare, health monitoring devices and other equipment connected to the phone line should be checked for compatibility. Finally, digital phone services require power in the home, so anyone who relies on their landline should ask their provider about available backup options.
