The impact of the PSTN switch-off on your business

The PSTN switch-off marks a pivotal moment in telecommunications, impacting your business’s connectivity and operations. But as the curtain falls on the Public Switched Telephone Network (PSTN), millions of UK businesses still rely on PSTN or ISDN services.

Several exchanges already have a stop-sell in place, meaning you can no longer provision new services like FTTC. In 2024, some exchanges will be switched off by Openreach. So, now is the time to act to avoid interruptions to your business.

What’s changing?

Openreach are disconnecting the old copper network and migrating all services to IP-based solutions.


A stop-sell is already in place, but by the end of 2025, all PSTN services will be inactive.


The current network is old and difficult to maintain, as well as not being in line with modern technologies.

What next?

Find out which technology in your business relies on these services, and make a plan to upgrade.
