The BT landline switch off is a nationwide change that will see traditional phone lines replaced by digital services. Businesses across the UK will need to move to VoIP phone systems to ensure continued communication and avoid disruption.
This change affects all services that rely on older analogue lines, including business phone systems, broadband connections, and some alarm or payment systems. Planning ahead is essential to avoid downtime and ensure a smooth transition to modern, internet-based telephony.
By upgrading to VoIP, businesses can not only stay connected but also benefit from improved flexibility, lower costs, and advanced features designed for modern working.
BT is phasing out traditional analogue phone lines (often called PSTN or ISDN) and replacing them with internet-based services. This means businesses must upgrade their phone systems before the switch off deadline.
How Does This Affect Your Business?


The BT landline switch off will affect over a million businesses across the UK, and all organisations still using traditional phone lines will need to upgrade. The deadline is approaching, and businesses that have not yet moved to a VoIP-based system will need to act to avoid disruption.
With the right provider, the transition to VoIP can be smooth and hassle-free, with minimal impact on day-to-day operations. In many cases, new systems can be installed outside of business hours, ensuring your phones continue to work without losing important calls.
We offer a free network survey to assess your current setup and ensure your business is ready for the BT landline switch off. Having surveyed thousands of business networks, we check your existing cabling, verify Power over Ethernet (PoE) capabilities for VoIP handsets, and test your broadband speed and reliability to ensure clear, uninterrupted call quality.
Following the survey, we provide clear recommendations to help you transition smoothly to a VoIP system with minimal disruption.
