Traditional copper phone lines are being phased out across the UK. Here's everything you need to know about switching to digital phone services.
The UK telecoms industry is undergoing a major transformation
By January 2027, the traditional Public Switched Telephone Network (PSTN) and Integrated Services Digital Network (ISDN) will be switched off completely across the UK.
This means all phone services must move to digital technology that works over broadband internet connections instead of old copper wires.
The copper wire network is over 100 years old and increasingly expensive to maintain. Digital technology offers better quality, more features, and greater reliability.
Anyone with a traditional landline phone service. This includes homes, businesses, and organizations that still use copper wire phone connections.
While the deadline is January 2027, it's best to make the switch sooner to avoid last-minute rushes and ensure a smooth transition.

Everything you need to know about the digital switchover
No! You can continue using your existing landline phone. The only change is that it will plug into your router instead of the wall socket. Most modern routers have a phone port (usually labeled "TEL" or "PHONE").
Yes! We can transfer your existing phone number to our digital voice service. This process is called number porting and typically takes 10-15 working days. There's a one-time transfer fee of £12.00.
Since digital phone services rely on your internet connection, they require power to work. We recommend having a mobile phone as a backup. For vulnerable customers who rely on their landline, battery backup units are available that can keep your router and phone running for several hours during a power outage.
Yes, emergency 999 and 112 calls will continue to work as normal. UK regulations require all digital phone providers to ensure emergency calls can be made even during power cuts, which is why battery backup solutions are important for households without mobile coverage.
No, digital voice calls use very little bandwidth – typically less than 100 kbps. Even basic broadband connections are more than sufficient for digital phone calls. You can make calls and use the internet simultaneously without any issues.
Some older alarm systems and medical alert devices may not work with digital phone lines. Before switching, check with the manufacturer of your device. Many can be upgraded or replaced with digital-compatible versions. If you have critical medical equipment, please contact us before making the switch so we can help ensure continuity of service.
The physical switchover is very quick – usually completed on the same day your broadband is activated. If you're transferring an existing number, the full process takes 10-15 working days. During this time, your old phone line continues to work normally until the transfer is complete.
Yes! Digital voice services typically offer HD voice quality, which provides clearer, crisper audio than traditional copper phone lines. You'll notice the improvement immediately, especially when calling other people who also have digital voice services.
Yes! Cordless DECT phones work perfectly with digital voice services. Simply plug the base station into your router's phone port instead of the wall socket, and all your cordless handsets will work exactly as before.
Digital voice requires an internet connection to work. If you don't currently have broadband, you'll need to get it before the 2027 switchover deadline. We offer affordable broadband packages that include digital voice service. Contact us to discuss the best options for your needs.
