The PSTN Switch Off. What Is Happening?

In January 2027, the PSTN (Public Switched Telephone Network) will be switched off.

This means that any home or business phone operating on the old analogue telephone network will have their landline switched off. This won’t just affect traditional landlines, but anything that relies on copper lines including ADSL and FTTC broadband, door entry systems, alarms, and EPOS and card machines.

Why The PSTN Switch Off Is A Good Thing.

Full fibre broadband is up to 25x faster and 5x more reliable than traditional copper line-based broadband.

Unified communications courtesy of integration with Microsoft Teams and CRMs will streamline business processes and improve collaboration.
Digital voice services and cloud-based phone systems are more scalable, and efficient, as well as being budget-friendly.
Cloud-based phone systems and digital voice services are much more efficient, flexible, and scalable. Plus, they’re more cost-effective in the long-term.
What and when

What Is Being Switched Off and When?

The PSTN switch off consists of two concurrent projects:

Both are earmarked for 2027, while the latter of these projects will ensure full fibre broadband reaches 85% coverage by the end of 2026. However, the roll-out is already well underway.

The Public Switched Telephone Network is the UK’s traditional telephone system that has been in use for more than a century. While it has served the UK’s telecoms network well since then, it uses obsolete copper wiring that has become fragile and impractical to maintain.

The PSTN has served as the basis for the UK’s telecoms since 1876. Almost 150-years later it has become – unsurprisingly – obsolete. Technology has come on leaps and bounds in the last few decades, and even in the last few years, with the advent of smart phones, the cloud, the IoT, etc. Newer digital technologies such as ultrafast fibre broadband have overtaken the PSTN, so BT Openreach have decided to switch off the PSTN in 2027 in order to focus on these more efficient and innovative technologies.

It’s estimated that, as of March 2023, at least 2 million UK businesses still operate on legacy phone lines and networks. If you’re one of them, it’s time to start making the switch and futureproof your business. By upgrading sooner rather than later to fibre broadband and digital voice services such as cloud-based phone systems and SIP trunks, you’ll get ahead of the competition and save yourself a headache down the line.

The PSTN will be switched off in 2027, but it’s highly recommended to get ahead of the game and start your switch sooner rather than later.

Most certainly! Just because you’ve gone digital doesn’t mean you have to lose your business’s established phone number. In fact, with the changeover, you’ll be able to make calls from anywhere, on any device, all from the same number. And if you want to change your number to something more memorable, that’s easy too.

We’d be happy to. We can get you up and running with cloud-based phone systems, digital voice services, and fibre broadband in no time. Get in touch today and we’ll arrange a free readiness assessment.
