PSTN Shutdown 2027
The Public Switched Telephone Network (PSTN) is being switched off in the UK. The final deadline is January 31st 2027. This means traditional landlines will be replaced with digital services. This will be primarily Voice over Internet Protocol (VoIP). The switch-off affects all phone lines and broadband services. This will transition them from copper-based lines to full-fibre networks.

Detailed Dreakdown:
- What is PSTN?
The PSTN is the traditional telephone network that uses copper wires to transmit voice calls. - Why the switch-off?
The PSTN is becoming increasingly expensive to maintain and is being replaced by more modern, digital technologies like VoIP. - What’s the new technology?
VoIP uses the internet to transmit calls, offering more flexibility and features than traditional landlines. - Who is affected?
Everyone who uses a traditional phone line, including businesses, will be impacted. - What do I need to do?
Businesses should review their systems, identify any reliance on PSTN lines (e.g., for alarms, payment terminals), and transition to digital alternatives like VoIP. - Why now?
The PSTN is becoming more fragile, and services may become unreliable as the switch-off approaches. - What about vulnerable customers?
The deadline was extended to January 2027 to allow more time for vulnerable customers and those relying on telecare services to transition. - What about equipment?
Some equipment, like alarm systems and payment terminals, may need to be upgraded or replaced to work with the new digital network. - Key benefits of the switch:
Increased reliability, higher call quality, greater flexibility, and more opportunities to digitize with advanced services.
