The UK Landline Digital Switchover: What It Means and What You Need To Do

The UK’s traditional copper‑based landline network — the Public Switched Telephone Network (PSTN) — is being retired. After decades of service, the PSTN has become outdated, increasingly unreliable, and expensive to maintain. As a result, all UK landline services are moving to modern digital phone technology, delivered over broadband.

This nationwide upgrade affects every home and business with a landline. Here’s what the change means, how it may affect you, and the steps you should take to stay connected.

Why Landlines Are Going Digital

Digital landlines run through your broadband router rather than the old wall socket. This shift allows providers to deliver clearer calls, more reliable service, and better long‑term support.

Ofcom explains the transition in detail on its official guidance page: 👉 https://www.ofcom.org.uk/phones-and-broadband/landline-phones/future-of-landline-calls

This change is part of the UK‑wide PSTN switch off, a major upgrade designed to modernise the country’s communication infrastructure.

What You Need To Do Before the Switchover

Before your provider switches your line, make sure you tell them if any of the following apply:

You use telecare alarms, health pendants, Lifeline devices, or security systems connected to your phone line.
You have a disability, mobility issues, or need extra help with installation.
You don’t own a mobile phone, or you have poor mobile signal at home.
You rely on your landline during emergencies.

Your provider will advise you on equipment changes (such as a new router or adapter) and ensure your setup continues to work safely.

How the Switchover Works

For most households, the change is simple:

Your phone will plug into your broadband router instead of the wall.
Your phone number stays the same.
You continue making and receiving calls normally.
Some customers may need new hardware — your provider will supply this if required.

If You’re on the BT Openreach Network

BT Openreach is retiring the old PSTN network by 31 January 2027. This means all customers using Openreach‑based services will be moved to digital landlines before that date.

BT’s official information on the digital switchover is available here: 👉 https://www.bt.com/help/landline/digital-voice (bt.com in Bing)

If your provider contacts you about switching, don’t ignore it — failing to respond could result in loss of service.

If You’re on Virgin Media O2, KCOM, or Another Network

Other providers are also retiring their legacy networks, but their timelines may differ. Your provider will contact you directly when it’s time to switch.

Telecare, Lifeline Alarms & Connected Devices

If you or someone in your household uses:

Telecare alarms
Health pendants
Personal emergency alarms
Any device that relies on the phone line

…you must tell your provider before the switchover.

Some older devices may not work correctly on digital lines, and your provider can pause the migration until a safe solution is in place.

Always check with the manufacturer before buying new equipment to ensure it’s compatible with digital landlines.

What Happens During a Power Cut?

Digital landlines rely on mains electricity. If your power goes out, your landline will stop working unless you have a battery backup.

If you depend on your landline and don’t have a reliable mobile phone or signal, your provider must give you a free backup solution lasting at least one hour (some last up to seven).

Even if your mobile has no signal on your usual network, emergency calls to 999 will automatically connect through any available network.

Extra Support for Elderly or Vulnerable Customers

If you are elderly, disabled, or have additional needs, your provider must:

Assess your situation
Offer tailored support
Provide clear information
Assist with installation
Ensure you remain safely connected

This is part of Ofcom’s consumer protection requirements.

If Something Goes Wrong

Start by contacting your provider. If they don’t resolve the issue, you can escalate it through their formal complaints process.

If the problem still isn’t fixed after six weeks (or you receive a deadlock letter), you can take the matter to an Alternative Dispute Resolution (ADR) scheme.

You can also report your experience to Ofcom’s Consumer Contact Team — while they don’t resolve individual cases, your feedback helps shape regulation.
