The traditional landline phone system in the UK is undergoing a major transformation. For decades, calls have been carried over the Public Switched Telephone Network (PSTN) — a copper-based system that has reliably connected people and businesses across the country.
However, with the rapid evolution of digital technology and increasing demand for flexible communication solutions, the PSTN will be phased out by January 2027. This means your landline calls will soon be delivered using Voice over Internet Protocol (VoIP) technology.
So what does this change mean for your business, and how can you prepare?
What Is the PSTN Switch-Off?
BT, along with other major UK telecom providers, will switch off the PSTN by 2027 to modernise national communications infrastructure. Traditional copper lines will be replaced with digital, internet-based technology. In simple terms, calls will now travel over your broadband connection instead of a phone line, marking a nationwide shift towards complete digitalisation.
What Does This Mean for Landline Users?
If your business relies on a landline, it’s crucial to understand the impact of this change:
- VoIP offers clear advantages: Better call quality, increased flexibility, and seamless integration with digital services.
- However, a broadband connection is essential. Landlines without internet will need upgrading to remain functional.
- Some businesses may need to check compatibility for systems like alarm panels, medical alert devices, or other PSTN-dependent technology.
For most, this will be a minor adjustment. Still, early awareness can ensure a smoother transition—especially for organisations using older systems.
How Can You Prepare?
- ✅ Check Full Fibre Availability: Use our availability checker and provide your postcode. We’ll help assess your fibre-readiness and discuss your upgrade options.
- ✅ Assess Your Connected Devices: Ensure any devices connected to your landline—like alarms or emergency alerts—are VoIP-compatible.
- ✅ Understand the Benefits: VoIP offers more than just continuity. It’s often more cost-effective, allows calls across multiple devices (like laptops and mobiles), and integrates with modern platforms for greater productivity.
Final Thoughts
The PSTN switch-off is a significant milestone in the UK’s digital transformation. While it may feel like a big change, embracing VoIP gives businesses the chance to modernise their communication setup, boost flexibility, and improve reliability.
