The BT Switch-Off
What it means for your business and how to prepare
The BT Switch-Off refers to the planned retirement of the UK’s traditional Public Switched Telephone Network (PSTN) and ISDN services. Originally scheduled for 2025, the deadline has now been extended to January 2027.
This transition will move all phone services to digital, IP-based networks such as VoIP (Voice over Internet Protocol) and fibre broadband.The goal is to replace outdated copper networks with faster, more reliable, and future-ready solutions that support the growing demand for digital services across the UK.
Why is the BT Switch-Off happening?
PSTN and ISDN technology is decades old and no longer suitable for today’s fast-paced, cloud-connected world. With more businesses relying on high-speed broadband, unified communications, and mobile technology, it’s essential that the UK’s infrastructure is modernised to keep up.
Moving to digital services will ensure better performance, improved security, and the flexibility needed for modern working.
Implications for your business
- You’ll need to move to digital – Traditional landline phone systems will stop working, so you’ll need to switch to VoIP or cloud-based alternatives.
- Legacy devices may need replacing – Equipment like fax machines, card machines, alarms or lift lines that depend on analogue signals may not be supported and could require upgrades.
- Delaying could risk disruption – If you don’t migrate in time, you could face unexpected downtime or loss of services.
What should you do now?
- Upgrade your communication systems – Start moving from PSTN or ISDN to a digital alternative such as VoIP or fibre. These offer improved flexibility, lower costs and more features.
- Assess any legacy equipment – Identify whether devices like alarms, payment terminals or fax machines rely on the old network and explore compatible digital alternatives.
- Plan your switch early with our support – Avoid downtime by working with us to create a clear, stress-free migration plan.
Why upgrade before the Switch-Off?
- Cost savings – Switching to VoIP or SIP-based telephony can significantly lower your call charges and eliminate costly line rental, particularly for long-distance and international calls.
- Future-proof technology – Moving to an IP-based communication system ensures your business is ready to adopt next-generation tools like cloud telephony, hosted PBX, and fibre broadband connectivity.
- Greater flexibility – Digital solutions enable seamless communication across multiple devices, making it easier for staff to work remotely or across different sites without loss of functionality.
- Improved reliability – Unlike legacy copper networks, fibre and IP-based infrastructure is more resilient to faults, delivering a more stable and consistent service for your business.
