Upgrading the UK to Digital Phone Lines

The humble copper wire has been the backbone of our telecommunications here in the UK and around the world for over a century. It has kept our hospitals, schools and emergency services connected, powered card machines on our high streets and delivered some of the most important phone conversations we’ve ever had with our family and friends. 

On the world stage, they’ve provided everything from maintaining vital and often life-saving communication during both World Wars, to relaying communications during the historic Apollo 11 moon landing mission.

During this time – the vast majority of phone calls in the UK have been handled by BT’s copper based public switched telephone network (PSTN) – an analogue system which connects people using specific phone numbers. 

But being around for as long as it has, the PSTN’s become outdated and difficult to maintain. Skills and parts are increasingly difficult to come by and new digital services like Voice over IP (VoIP) - where voice calls are transmitted the same way your broadband works, have become increasingly popular.

Our parent, BT Group signalled their intention to retire the PSTN network by 31st January 2027 – and we’ve been working to withdraw any Openreach products that work over it – which come under the umbrella term of Wholesale Line Rental (WLR).

WLR is used by a number of our Communications Provider (CP) customers, and we’ve been working closely with them for years to help them prepare for the change. For example, helping them to identify their vulnerable customers – those who might rely on their old copper line – early on. And we’re collaborating with various organisations to raise awareness of the change and make sure they have all the information and support they need.

As part of this whole process, we’re now taking the significant step of ending the sale of new analogue services across the UK. That means from today, when customers sign up for a new contract - or when they switch, upgrade or re-grade their service via their provider - they’ll be moved onto a new digital line rather than an analogue one.

Ideally, the new service will be delivered over our brand-new Full Fibre network - which is already available to 11m homes and businesses nationwide – but, where that’s not available, we’ll move them onto a digital alternative.

We’ve already made lots of progress in getting CPs to encourage their customers to ‘go digital’ in this way, and more than 500 of our exchange areas – covering some 4.6m premises – are now in this ‘stop sell’ phase. But with just under 10 million lines still left to convert there’s still a lot of work to do and we’d urge any CP using our network and unsure of the next steps – to get in touch.

In the ever-evolving landscape of technology, the transition from traditional copper wires to advanced digital fibre optic lines has emerged as a game-changer, revolutionising the way we communicate, access information, and connect with the world. This shift is not just a minor upgrade; it's a leap into the future of faster, more reliable, and efficient data transmission. 

By modernising the telephone network, we’ll be able to do more than ever before, helping the UK to stay competitive on the global stage. 

To enable this change, everyone from businesses both big and small, to data hungry families, and elderly relatives whose landline is their lifeline – will need to answer the call and get ready for the Upgrade to Digital Phone Lines.

The future is calling, and it's time to pick up.
