When Are Landlines Being Phased Out & How to Prepare
July 25, 2023
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.
What will happen to landline phones in 2025?
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.
How are landlines being phased out?
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.
Why are landlines being phased out?
Legacy landlines are outdated when compared with modern technology, while the costs involved with running and maintaining PSTN and ISDN lines are no longer cost-effective.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.
Landline owners: What you need to know
Below are a few key points that landline owners should know ahead of the 2025 switch off:
- The Big Switch Off relates to landline networks and devices: you won’t need to switch mobile devices.
- Existing landline phones that are connected with cables will still exist but will utilise digital internet technology rather than analogue.
- The main change going forward is that homes, businesses, and offices will use VoIP rather than traditional landlines. VoIP converts data into digital packets that are transferred over broadband networks via a router.
- VoIP systems allow you to make phone calls with a range of devices, including PCs, laptops, smartphones, tablets, and more. This is important, as employees are continually utilising a range of devices in any given working day; view our insightful blog that discusses whether we can do a full day’s work from our smartphones.
What lines will the landline shutdown affect?
The landline shutdown will affect all lines supported by PSTN and ISDN, including:
- WLR – learn more about WLR withdrawal in our helpful guide
- ISDN2
- ISDN30
- Local Loop Unbundling Shared Metallic Path Facilities (LLUSMPF)
- Narrowband Line Share
- Classic Products
If your home or business still relies on any of these lines, it’s time you prepare to upgrade.
What other devices will the landline phase-out impact?
In addition to business and home landlines, the landline phaseout will also affect other services that use ISDN and PSTN lines, including:
- Alarms
- CCTV systems
- EPOS machines
- Payment terminals
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.
Who will be affected by the landline switch off?
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.
How can I transfer landline-reliant services to digital networks?
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
What are some alternatives to traditional landlines?
There are a range of fibre-based technologies that will replace traditional landlines, including:
- Voice over Internet Protocol (VoIP)
- Session Initiation Protocol (SIP)
- Single Order Generic Ethernet Access (SoGEA)
- Fibre to the Premises (FTTP)
Which system should I upgrade to?
The system you upgrade to will depend on the specific requirements of your business. There are plenty of features and benefits of each system, so you’re best off speaking to an expert who can find out what it is you’re after.

How does VoIP work?
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.
What are the advantages of IP technology over traditional landlines?
Advantages of IP technology over traditional landlines include:
- Better call quality: IP systems can process more high-quality data, improving the quality of your calls.
- Quicker data transmission speeds: VoIP systems transit data quicker than traditional landlines.
- Reliability and efficiency: VoIP systems are more reliable and efficient than traditional lines.
- Increased flexibility and connectivity: IP systems make it easier to stay connected wherever you are.
- Cost-effective: Running calls over the internet costs less, while VoIP systems require less money spent on hardware and maintenance.
- Helpful features: Take advantage of modern features that aren’t always available on landlines, such as voicemail, call recording, call handling, and more.
- Scalability: IP systems are easy to scale up and down compared to traditional lines.
Frequently asked questions
Can I keep my landline after 2025?
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.
What do you need to use an internet-based phone service?
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.
Do I need a landline for broadband?
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.
What is a digital phone line?
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.
Will I need an internet connection to make a phone call?
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.
Can I keep my current phone numbers?
In most cases, you’ll be able to keep your current number.
