By January 2027, the UK’s traditional landline network—the Public Switched Telephone Network (PSTN)—will be switched off permanently. This marks the end of copper phone lines that have carried the nation’s calls for decades. For millions of households and businesses still relying on these old connections, the clock is ticking: you’ll need to move to a digital alternative before the cutoff.

If you haven’t already switched, expect to start receiving letters or emails from your broadband provider about “Digital Voice” services or VoIP (Voice over Internet Protocol).

You’re probably wonder how to switch your landline to VoIP?

But there’s no need to panic. The changeover doesn’t have to be complicated, and with the right preparation it can actually make your phone service more reliable, more flexible, and in some cases even cheaper.

In this guide, we’ll walk you through:

  • How to switch from PSTN to VoIP step by step
  • How to keep your existing landline number
  • What equipment you’ll need (and what you don’t)
  • Which providers offer the best VoIP packages in the UK right now

Whether you’re a homeowner wanting a simple setup or a business looking for advanced features, this guide will help you make a smooth, stress-free transition into the UK’s all-digital future.

How to switch your landline to voip

Understanding the Landline Switch-Off

What is happening?

The UK’s Public Switched Telephone Network (PSTN)—the copper-wire system that has powered landlines for decades—is being permanently retired. From now on, all calls will be delivered over digital, internet-based networks (IP/VoIP) instead.

When will it happen?

The nationwide switch-off will take place in January 2027. While the original deadline was set for December 2025, the timeline has been extended to give households and businesses more time to adapt. Importantly, many areas have already entered “stop-sell” status, meaning no new traditional landline services can be ordered—and in some cases, existing ones cannot be modified.

Why is it happening?

The copper landline network is:

  • Outdated – designed for an era of voice-only communication.
  • Costly to maintain – repairs and upkeep are no longer sustainable.
  • Limited – unable to meet modern digital needs like broadband and smart services.

By moving everyone to VoIP (Voice over Internet Protocol), the UK will gain a simpler, more resilient communications infrastructure—while unlocking new features such as multi-device calling, better integration with broadband, and improved reliability.

Who is affected?

Anyone still using a traditional landline connection will be impacted. This includes:

  • Households with standard home phones
  • Businesses with desk phones connected to copper lines
  • People using telecare devices, alarm systems, or emergency call pendants that rely on the PSTN

In short: if your phone plugs into the wall rather than your router, you’ll need to switch.

What Is VoIP (and Why You’ll Need It)?

Definition

VoIP (Voice over Internet Protocol) is the technology that replaces traditional landlines. Instead of running over copper wires, your phone calls are transmitted through your broadband internet connection. If you’ve ever used services like Zoom, WhatsApp, or Skype, you’ve already experienced VoIP in action—only now, it’s becoming the standard for all UK landlines.

Key Benefits

  • Lower costs – no more expensive line rental; many VoIP plans are bundled with broadband.
  • Crystal-clear call quality – with HD voice, conversations sound sharper and more natural.
  • Extra features at no extra cost – voicemail delivered to your email, call forwarding, call blocking, and mobile apps that let you take your landline number anywhere.
  • Keep your number – your existing landline number can usually be transferred (“ported”) to VoIP, so you won’t lose touch with friends, family, or customers.
  • Future-ready – VoIP integrates seamlessly with modern digital services, from smart home devices to unified business communications.

Things to Be Aware Of

  • Dependent on power and internet – unlike copper lines, VoIP won’t work during a power cut or broadband outage unless you have a backup (such as a battery pack, mobile phone, or failover solution).
  • Compatibility issues – some older telecare alarms, lift phones, and security systems may not work reliably on VoIP without an upgrade or replacement.

Switching from Landline to VoIP with Plexatalk

The UK landline switch-off is coming — but moving to digital doesn’t need to be complicated. At Plexatalk, we make the transition smooth, reliable, and stress-free. Here’s how the process works:

Step 1: Check Your Broadband

VoIP runs over your internet connection, so you’ll need a stable service.

  • Minimum speed: 0.5 Mbps upload/download per call
  • Recommended: 10 Mbps+ if multiple people are using the internet at once
    If you’re unsure, we’ll help you test your connection.

Step 2: Choose Your Plexatalk Plan

We provide flexible VoIP packages for homes and businesses. With Plexatalk, you’ll benefit from:

  • Crystal-clear call quality
  • Easy number porting
  • Competitive rates on UK and international calls
  • Friendly UK-based support whenever you need it

Keeping Your Old Landline Number

We know how important it can be to hold on to a familiar phone number — whether it’s a number your family has used for decades or a business contact line your customers already know. The good news is: you don’t have to lose it when you switch to VoIP.

Ofcom Protection

UK regulator Ofcom requires all providers to support number portability, which means you can transfer (“port”) your old landline number onto your new VoIP service with Plexatalk.

How to Make It Smooth

To avoid delays, follow these simple steps:

  • ✅ Don’t cancel your landline before porting — the number must remain active until the transfer is complete.
  • ✅ Check your account details carefully — make sure the name, address, and account holder match your existing provider’s records.
  • ✅ Ask for a porting date — we’ll confirm the estimated timeline (usually 7–14 days).

At Plexatalk, we manage the process for you from start to finish, so keeping your number is simple and stress-free.

Equipment You May Need

Switching to VoIP doesn’t always mean buying lots of new kit — in many cases, you can keep your existing phone. Here’s what you might need, depending on your setup:

  • Broadband Router with VoIP Ports
    Some internet providers supply routers with built-in phone ports (for example, BT’s Smart Hub 2). If your router has this feature, you can often just plug in and go.
  • ATA (Analogue Telephone Adapter)
    This device allows you to keep using your traditional landline handset by converting it into a VoIP-compatible phone.
  • VoIP Handsets
    Purpose-built phones designed for internet calling, offering features like HD voice and easy integration with business systems.
  • Battery Backup (UPS)
    Unlike copper lines, VoIP requires power. A UPS (Uninterruptible Power Supply) can keep your service running during a power cut.

What Plexatalk Provides

At Plexatalk, we can supply:

  • ✅ VoIP handsets
  • ✅ ATA adapters (for using your existing phone)

We don’t provide routers or UPS units, but we’ll happily advise you on the best options for your setup.

Costs – Is VoIP Cheaper?

For most households and businesses, yes — VoIP is more cost-effective than a traditional landline.

  • Old landline rental: Typically £15–£20 per month (just for the line, before call charges).
  • VoIP services: Often start from as little as £5–£10 per month, with many packages including unlimited UK calls.
  • Business-grade VoIP: Costs a little more, but includes advanced features like call forwarding, voicemail-to-email, call recording, hunt groups, and mobile integration — tools that would cost far more on traditional landline systems.

By moving to VoIP, many households and organisations actually save money by dropping line rental while gaining more flexibility and features.

Backup & Safety Considerations

One of the biggest questions people ask about VoIP is: “What happens in a power cut?”

With the old copper network, landlines worked independently of mains electricity. VoIP is different — it relies on your broadband router and an internet connection, both of which need power to function.

The Good News

There are reliable solutions to keep you connected:

  • Battery Backup Units (BBUs): Ofcom requires providers to offer backup power options, usually free of charge for vulnerable users who rely on their phone for emergencies.
  • Routers with 4G Backup: Some broadband providers supply routers that automatically switch to mobile data if your internet goes down.
  • Mobile Phones as Fallback: In most cases, your mobile will be the fastest backup option for emergency calls.

How Plexatalk Helps

At Plexatalk, we:

  • ✅ Provide advice on the best backup solutions for your home or business
  • ✅ Supply VoIP equipment (handsets and adapters) ready to integrate with backup power
  • ❌ Don’t supply 4G/5G routers or UPS units — but we’ll guide you on what’s best for critical environments like healthcare, security, or telecare

With the right setup, VoIP can be just as reliable as your old landline — and much more flexible.

Why Switch Your Landline to Plexatalk VoIP?

As the UK prepares for the landline switch-off, there are plenty of VoIP providers out there — but not all are created equal. Many households will be automatically moved to big-brand services like BT Digital Voice or Vodafone’s VoIP add-ons, while businesses may be pushed toward complex corporate platforms.

At Plexatalk, we do things differently. We combine the reliability of enterprise-grade VoIP with the personal support and fair pricing that the big players can’t match.

For Households

  • Keep your number — we handle number porting from start to finish.
  • Simple setup — whether you want to keep your old handset, upgrade to a VoIP phone, or use our mobile app.
  • Affordable pricing — starting from just a few pounds a month, often cheaper than traditional line rental.
  • Friendly UK-based support — real people at the end of the phone, not endless call queues.

Common Problems & Troubleshooting

Switching to VoIP is usually straightforward — but like any technology, things don’t always go perfectly the first time. Here are some of the most common issues and how to solve them.

Poor Call Quality

  • Check your internet speed and stability.
  • Use a wired Ethernet connection instead of Wi-Fi where possible.
  • Avoid heavy downloads/streaming during calls.

Phone Won’t Ring

  • Double-check your ATA (analogue telephone adapter) or handset settings.

Telecare or Alarm Devices

  • Some older telecare, lift, or alarm systems may not be fully compatible with VoIP.
  • Always confirm with your device provider, or ask Plexatalk for advice on upgrade options.

Number Porting Delays

  • Porting usually takes 7–14 days, but delays can happen if account details don’t match exactly.
  • Make sure the account name, address, and line owner details are correct.
  • Ofcom requires providers to port numbers promptly — and Plexatalk will keep things moving for you.

Preparing Elderly or Vulnerable Users

The landline switch-off affects everyone — but it’s especially important to prepare if you or a family member is elderly, vulnerable, or rely on telecare/medical devices.

Ofcom Requirements

Ofcom requires all providers to:

  • Identify vulnerable customers (such as those with telecare, alarms, or health pendants).
  • Provide backup solutions so that emergency calls can still be made during a power cut or broadband outage.
  • Ensure continuity of service — meaning customers aren’t left without a safe way to call 999.

What Families Should Do

  • Check device compatibility – Some older telecare and alarm systems may not work with VoIP. Contact your device supplier to confirm, and speak to Plexatalk for advice.
  • Ask about backup power – Vulnerable users are entitled to free or low-cost battery backup units (BBUs) to keep phones working during outages.
  • Label new equipment clearly – Simple labels on new adapters, routers, or handsets can reduce confusion and make the transition easier for older relatives.
  • Keep a fallback option – Always ensure there’s a mobile phone or other backup available for emergencies.

How Plexatalk Helps

  • ✅ We flag vulnerable users during setup to make sure Ofcom requirements are met.
  • ✅ We advise on compatible equipment for telecare and alarms.
  • ✅ We’ll guide families step by step through testing and labelling, so everything is easy to use.

The Future Beyond 2027

By January 2027, the UK’s PSTN landline network will be gone for good. From that point forward, every household and business will rely on digital voice services (VoIP) or mobile phones for calling.

What to Expect After the Switch-Off

The end of copper landlines isn’t just about replacing old technology — it’s about opening the door to new possibilities:

  • Smarter calling features – from AI-powered voicemail transcription to intelligent spam call blocking.
  • Better integration – your landline number working seamlessly across mobile, desktop, and smart devices at home.
  • Future-ready communications – digital voice services that evolve with broadband, 5G, and beyond.

A New Era for the Landline

The traditional landline as we knew it — powered by copper wires — will no longer exist. Instead, landline calling will be fully digital, offering clearer quality, lower costs, and far more flexibility.
