Is BT turning off landlines in 2025? Yes.
Is BT turning off landlines in 2025? Yes. By December 2025, BT will permanently switch off the UK’s outdated ISDN and PSTN networks—the copper-based systems that have powered landlines for decades. This isn’t just about phones: alarms, EPOS machines, CCTV, and even some lifts rely on these networks, so businesses and households need to act now to avoid disruption.
Why the Change?
The old copper infrastructure is Victorian-era tech, and ISDN (introduced in the 1980s) simply can’t keep up with modern needs. Maintaining it is costly, and with the rise of internet-powered communication, clinging to ISDN is like using a fax machine in a Zoom world. VoIP (Voice over Internet Protocol) replaces clunky landlines with internet-based calls, offering faster speeds, lower costs, and features like video conferencing, instant messaging, and CRM integrations.
Key Dates
- 2024–2025: Regional shutdowns begin, starting with pilot areas like Salisbury and Mildenhall.
- December 2025: Full shutdown. Copper lines go dead nationwide.
Risks of Delaying
- Sky-high costs: Repairing old systems will become pricier as parts vanish.
- Falling behind: Competitors using VoIP will leverage AI tools, analytics, and remote working perks you can’t access.
