As of January 31, 2027, BT and all major UK telecom providers will retire the traditional Public Switched Telephone Network (PSTN) and Integrated Services Digital Network (ISDN), thereby ending analogue landline services nationwide (GOV.UK). The UK government and industry have delayed the cut-off from the original 2025 target to protect vulnerable customers, especially those using emergency telecare devices, allowing additional support and transition time.
Businesses still operating on analogue or ISDN lines face increasing infrastructure fragility, risk of outages, and unsupported equipment. Call-dependent systems, such as EPOS terminals, alarm systems, CCTV integrations, and fax machines, may stop working unless they are migrated ahead of time (BT Business).
Migration Timeline & Planning Advice
- Stop-sell is already active: Providers stopped selling new PSTN/ISDN lines years ago.
- Recommended business migration deadline: End of December 2025 to avoid service risks (circle.cloud).
- Final cut-off: January 31, 2027, for all analogue services.
