By 2027, every home in the UK will experience a major change in the way phone lines and connected devices work. Known as the digital switchover, this transition will see the end of the UK’s long-standing analogue phone network meaning traditional landlines, and many devices that use them, will stop functioning unless upgraded.
For most people, this may sound like a technical issue that only affects businesses, but every UK household will be affected, and it’s important to understand what the switchover involves, what steps you need to take, and how to make sure your home is ready for a fully digital future.
What is the digital switchover?
The digital switchover refers to the retirement of the Public Switched Telephone Network (PSTN), which has powered traditional landline services in the UK for decades. Alongside PSTN, the Integrated Services Digital Network (ISDN) will also be phased out. These systems are being replaced with modern, IP-based technology (Internet Protocol), meaning all phone services will soon run over the internet.
From January 2027, landline phones will no longer work unless they are connected to a digital phone service, also known as VoIP (Voice over Internet Protocol). This means your calls will travel over your home broadband connection rather than through copper telephone wires.
Why is this happening?
The PSTN was first introduced in the UK in the 20th century, and although it has served households well for generations, the infrastructure is now outdated and expensive to maintain. Telecom providers are focusing their efforts on building faster, more reliable digital networks such as full fibre broadband which offer better service, more features, and greater long-term sustainability.
The digital switchover is part of the UK’s broader digital transformation strategy, aimed at improving nationwide connectivity and supporting the increasing demand for internet-based services across homes, businesses, and communities.
How will this affect me?
If your household currently uses a traditional landline phone, it will stop working when the PSTN is switched off unless you've switched to a digital phone service.
This change could affect more than just voice calls. Other devices that rely on a landline connection such as telecare systems, personal alarms, some burglar alarms, or even fax machines may also stop working unless they're upgraded or replaced with digital alternatives.
If you don’t use a landline, you may assume you’re unaffected. However, many people still have phones plugged into wall sockets for convenience, emergencies, or as a backup when mobile signal is poor. It's important to know whether your setup depends on analogue infrastructure and make the necessary updates.

What do I need to do?
Your analogue landline service will need to be migrated to a VoIP system as part of the switchover (depending on your phone, an adapter could be used to enable your handset to become a digital phone). Instead of plugging your phone into a traditional wall socket, you’ll plug it into your router, or an adapter provided by your broadband supplier.
VoIP phones look and work very similarly to traditional handsets, you can keep your number, make and receive calls in the same way, and you’ll still be able to use call features like voicemail, caller ID, and call waiting.
If you’re unsure whether your current phone is compatible, contact your provider for guidance. In some cases, a new handset or a VoIP adapter may be needed.
One key difference with digital phones is that they rely on your home’s power supply and internet connection. This means that in the event of a power outage or broadband failure, your phone may stop working which could be problematic during an emergency.
To mitigate this, there are two main options:
If you or someone in your household is vulnerable or relies on a personal alarm system, speak to your service provider now. They are required to offer alternative arrangements to ensure continued access to emergency services.
If you have devices like telecare alarms, medical alert systems, or home security systems that connect via a phone line, these will need to be checked. Many older models are not compatible with digital networks and will need to be upgraded to IP-enabled alternatives.
Speak to your device provider or the manufacturer for advice. Many services are actively reaching out to customers to help them transition ahead of 2027.
Because digital phones run over your broadband, your internet connection becomes even more important. If your current broadband struggles with streaming, video calls, or gaming, it may not be ready to support additional VoIP traffic.
VFast recommends testing your connection and considering a speed upgrade or even full fibre broadband if available in your area. A strong, stable connection will ensure that your digital phone works reliably, especially during peak usage times.
What if I don’t want a landline anymore?
Some households may see the switchover as a good time to cut the cord altogether. With mobile phones now offering unlimited call plans, some people may decide to stop using a home phone altogether. That’s absolutely fine as there’s no requirement to maintain a landline after the switchover unless you need or want one.
However, if mobile coverage in your area is poor or unreliable, keeping a landline, in its new digital form may still be the most practical option.
Final Thoughts
The 2027 digital switchover marks a major milestone in the UK’s communications infrastructure. While it may seem like a behind-the-scenes update, the change will impact millions of households and the way we stay connected.
The good news is that preparing is relatively straightforward and VFast is here to help. Whether you’re upgrading your phone, improving your broadband, or planning for power cuts, we can provide the guidance and solutions you need to stay connected without disruption.
