By the end of 2025, traditional landline phones are due to be fully phased out, representing a significant change to the UK’s phone network. This applies to both home and business lines, so anyone still relying on old, analogue networks need to prepare for the switch off. This helpful guide explains why landlines are being phased out and how you can prepare.
By December 2025, BT plans to have fully switched off the old, copper landline network that’s been in use for over a century. The gradual phasing out of the ISDN and PSTN means that landline networks will no longer function beyond December 2025. Instead, calls on all phones will be serviced by Voice over Internet Protocol (VoIP). As calls will require an internet connection, landlines that don’t have this capability will become defunct. You can learn more about the ISDN Switch Off and the PSTN Switch Off in our helpful blogs.
Landlines tend to use one of two networks: ISDN or PSTN. BT stopped the purchase of both lines in 2020 to gradually reduce them, with the plan to entirely switch them off by the end of 2025. Individuals and organisations that still rely on landline phones should look for alternatives sooner rather than later. Learn more about whether businesses are ready for the Big Switch Off in 2025.
Legacy landlines are outdated when compared with modern technology, while the costs involved with running and maintaining PSTN and ISDN lines are no longer cost-effective. The inefficiencies are stark when compared with the more cost-effective and convenient VoIP systems. While ISDN and PSTN have been cornerstones of worldwide communication for decades, they’ve barely changed in response to the increasingly digital, dynamic, and interconnected world. Neither network has the capacity to handle such large quantities of data that are standard in a hyper-connected world, so more advanced solutions are necessary. IP data is the primary solution.
Below are a few key points that landline owners should know ahead of the 2025 switch off:
The landline shutdown will affect all lines supported by PSTN and ISDN, including:
If your home or business still relies on any of these lines, it’s time you prepare to upgrade.
In addition to business and home landlines, the landline phaseout will also affect other services that use ISDN and PSTN lines, including:
Ultimately, any devices that utilise ISDN or PSTN will no longer function. With that in mind, it’s essential that businesses and individuals require handsets that are compatible with Internet protocol (IP) technology ahead of the 2025 deadline.
Any individual or business that still relies on the ISDN or PSTN will be affected when they switch off in 2025. Therefore, it’s essential you plan ahead and find a communications solution that best meets your needs.
Transferring landline-reliant services to their digital counterparts is relatively straightforward, although you will need to discuss the best way to proceed with your phone provider. Plus, it’s likely that you’ll be able to keep your current numbers after the migration. If you’ve not transferred your services over yet, the best advice is to contact your provider as soon as possible
There are a range of fibre-based technologies that will replace traditional landlines, including:
The system you upgrade to will depend on the specific requirements of your business.

VoIP systems use an internet connection to make phone calls, converting analogue voice signals into digital signals over a broadband connection. VoIP systems can connect calls to other networks, and require a reliable internet connection. You’ll also need a SIP-compatible desk phone or VoIP calling software that can be installed on a computer or smartphone. This means that the device you use will have an individual IP address so that calls can be made from your internet connection. VoIP systems store data in the cloud and are generally managed through an online dashboard. Here, you’ll likely find your contacts, phone numbers, features, and more.
Advantages of IP technology over traditional landlines include:
Your existing landline will likely still work after the switchover, although you’ll need to connect it to your broadband router with an adapter. As always, it’s best to check with your provider if there’s anything you’re unsure about.
A reliable internet connection is the most important requirement when switching to an internet-based phone service. You’ll also need devices that are capable of connecting to VoIP.
You don’t need a landline for a broadband connection. Traditional landlines will be axed in 2025 as part of the Big Switch Off, so anyone who’s not switched over to a digital network should find a solution that suits their needs.
A digital phone line uses the internet to deliver all services, including phone calls. Digital phone lines carry voice and data by converting analogue signals into digital signals, enabling more information to be transferred over a single connection.
Once the PSTN and ISDN are switched off in 2025, you’ll require an internet connection if you want to make a call with your landline.
In most cases, you’ll be able to keep your current number.
