You may have heard that a major change is coming to the UK’s phone network over the next couple of years. By the end of 2026, traditional landline phones, using 100-year-old technology, are set to be switched off in favour of a digital network fit for the modern era.
This will apply to both home and business phone lines, so if you’re still relying on analogue equipment, you’ll need to make plans now to upgrade.
Migrating early to digital telephony solutions will be especially important for small businesses, freelancers and startups. These firms can’t afford to be left without communications, and if they leave their planning too late, they could find themselves overpaying for unsuitable services in order to hit the deadline.
However, the impending switch off is more than just a necessity. It’s also a great opportunity for less-sizable businesses to move to technologies that were previously only affordable or practical for larger companies. This offers them the chance to level up their communications with more advanced features and compete on an even footing.
So what will the new communications landscape look like after the landline phones’ 2026/27 switch-off, and why do you need to pay attention to it?
What will happen to landline phones after 2026?
At the end of 2026, BT Openreach, the organisation responsible for building and maintaining the UK’s phone network, will turn off the country’s analogue public switched telephone network (PSTN) as part of the ongoing digital switchover.
This means that existing hardware and infrastructure that relies on this technology will no longer function. Instead, you’ll need handsets that can use internet protocol (IP) technology to transmit voice in a digital format using a broadband connection when you make or receive a phone call.
How will landline phones be phased out by the end of 2026?
The work to replace analogue networks is being handled by Openreach, which has already begun turning off circuits in some areas. The next step which came in early September 2023 meant it has stopped accepting new orders for PSTN systems altogether ahead of the full switch-off in 2027.
This will also include the switch off of Integrated Services Digital Network (ISDN), as these also rely on landline cables, even though they transmit data digitally. As such, anyone with a PSTN or ISDN connection will need to make plans now to move away from these solutions.
Why are landline phones expected to be phased out in 2027?
The main reason for the switch is that older analogue technology is getting less reliable and more expensive to maintain. PSTN and ISDN cannot support the speed and scalability that today’s communications need.
Many parts of the UK’s network have therefore become very outdated. In fact, some of the copper cables that still support the UK’s landline network have been in place since the 19th century, so Openreach has decided the time has come for a modernisation.
What should owners of landlines know about the landline phase-out in 2026?
While the technology will change, the terminology may not, and you won’t have to switch to mobile devices. ‘Landline’ phones that are connected via cables will still be around – they’ll just use digital internet technology rather than analogue.
Instead of traditional landlines, your office phones will use what’s known as Voice over Internet Protocol, or VoIP. This converts audio into digital data packets that are then sent over broadband networks via your router.
It’s easy to set up, and means you can make phone calls through a range of devices, including desktop and laptops PCs and smartphones, as well as VoIP-enabled desk handsets.
However, it does mean that once you’ve moved to a digital phone line, anything else plugged into the old telephone wall socket may stop working, or need additional equipment to be purchased and plugged in to enable it to work. Therefore, firms should start making plans now to ensure all their phone-based services are migrated to digital technology.
