Brits relying on the copper-wire telephone system will be facing its permanent switch-off by January 31, 2027. BT OpenReach will shut the UK’s ageing analogue Public Switched Telephone Network (PSTN), bringing an end to the traditional system that has been in service since the 19th century. This means that instead of plugging a telephone handset directly into a traditional wall socket, home phones will now plug into a broadband router.
The upgrade promises clearer call quality, greater reliability, and fewer faults than the deteriorating analogue network. However, it will change how landlines operate. Because digital landlines rely on broadband and mains electricity to function, they will stop working during a power cut unless households have a backup power solution in place.
For the vast majority of consumers, the transition is expected to be straightforward. But officials and telecoms providers are urging households to act now rather than leave it until the last minute, advising consumers to contact their provider as soon as possible to arrange the switch.
Residents should also make sure equipment connected to phone lines – such as telecare devices, health pendants, burglar alarms, CCTV systems, and payment terminals – are fully compatible with the new digital network and transition to modern broadband options, such as Full Fibre, where available.

Among the systems dependent on PSTN is telecare. AgeUK says the system uses technology to enable people to live more independently and securely in their own homes – such as a device that triggers an alert if gas is accidentally left on, or a personal alarm enabling someone to summon assistance following a fall. Those households will be affected by the switchover. Telecoms companies have been working alongside local councils to pinpoint telecare users, officials say.
Companies are also reportedly providing extra support to telecare users during the transition, including free engineering visits and battery back-ups for telecare equipment and landlines where necessary. Now a new official warning has been issued to households as the deadline nears.
OpenReach is now alerting customers that the deadline is rapidly approaching and urging them not to put it off, or risk losing essential services.
UK Households Face a Major Change to Landline Phones in January After 150 Years
For generations, the familiar landline telephone has been a fixture of British homes. From families keeping in touch with relatives to older residents relying on a dependable way to call for help, the traditional phone line has played a central role in everyday life. Now, after approximately 150 years of telephone history, the technology behind Britain’s traditional landline network is approaching a historic turning point.
From 31 January 2027, the traditional Public Switched Telephone Network, known as the PSTN, is scheduled to be retired across the Openreach network. The change will affect households that still depend on conventional copper-wire telephone services, requiring them to move to digital alternatives. <Cite refs={[“turn354667search0″,”turn354667search11”]}/>
For many households, the transition should be relatively straightforward. Existing telephone handsets can often continue to be used, although they will generally need to connect to a broadband router or compatible digital equipment rather than directly to the traditional wall socket.
But the change has raised concerns about people who depend on their landlines for essential communication, particularly older people, residents with disabilities and households in rural areas where mobile coverage is unreliable.
The transition is therefore about more than replacing an old telephone network. It is also a test of whether Britain’s telecommunications industry can modernise its infrastructure without leaving vulnerable customers behind.
Why the Traditional Landline Network Is Being Switched Off
The traditional telephone network was designed for an era when voice calls travelled through dedicated physical connections. Over decades, this system became a fundamental part of Britain’s communications infrastructure, connecting homes, offices and public services.
However, the copper network is ageing, becoming increasingly difficult to maintain and no longer matches the direction of modern telecommunications technology.
Digital voice services carry calls through internet-based connections, allowing providers to deliver telephone services using broadband infrastructure. The transition is part of a wider technological change in which communications systems increasingly depend on digital networks rather than older analogue equipment.
Openreach, which operates much of the UK’s landline infrastructure, says the old network is scheduled to be withdrawn on 31 January 2027. Households that have not switched by then could face restricted service or temporary emergency voice-only arrangements, depending on their circumstances and provider. <Cite refs={[“turn354667search0″,”turn354667search1”]}/>
Telecommunications companies have already transferred millions of lines to digital services. Nevertheless, a significant number of customers remain to be migrated, making the final months before the deadline particularly important.
The change does not mean that every household must abandon its home telephone. Instead, the technology delivering the service is changing.
What Will Happen to Your Home Telephone?
For most customers, the new arrangement will involve connecting their telephone handset to a broadband router or an adapter supplied by their provider.
In many cases, customers will be able to retain their existing telephone number and continue making and receiving calls much as they do today. A new handset may not be necessary, although some equipment may require replacement or additional adapters.
Providers are expected to explain the process to affected customers and identify what equipment is needed.
Households should not assume, however, that every existing telephone or connected device will automatically work with the new service.
Older telephone systems, security equipment and certain specialist devices may depend on the traditional network. These need to be checked before a household completes its transition.
Customers who have not received clear instructions should contact their telephone provider rather than wait until the deadline approaches.
The key point is that the landline itself is not necessarily disappearing. The traditional technology supporting it is being replaced.
The Power-Cut Problem That Has Raised Concerns
One of the most significant differences between traditional and digital landlines concerns electricity.
Traditional analogue telephones could often continue operating during a household power cut because the telephone network supplied the necessary power through the line. Digital landlines generally depend on a broadband router and equipment that require mains electricity.
If the electricity supply fails, the router may stop working, meaning that the home telephone could become unavailable unless an appropriate backup arrangement is in place.
This creates particular difficulties for households that rely on their landline as their only reliable way of contacting emergency services.
The concern is especially serious in remote communities where mobile signals may be weak or unavailable. A power cut that affects broadband equipment and mobile infrastructure could leave residents with fewer options for contacting the outside world.
Ofcom advises customers who rely on a landline and lack a working mobile phone or reliable mobile coverage to tell their provider before the switch. Providers must ensure that affected customers have a way to contact emergency services during a power cut, including an appropriate backup solution. <Cite refs={[“turn354667news6″,”turn354667search11”]}/>
Customers should ask their provider what backup equipment is available, how long it will operate and whether it will support their particular needs.
A battery backup may help maintain service temporarily, but it is important to understand its limitations and have an alternative emergency plan where possible.
Older People Could Face the Greatest Difficulties
For many younger households, switching to a digital landline may be a minor technical adjustment. For some older residents, however, the process could be more complicated.
A traditional telephone is often familiar, simple to operate and independent of a household’s everyday internet use. Some people have used the same handset and telephone number for decades and may not have broadband or a mobile phone.
Others may have hearing difficulties, limited mobility or health conditions that make installing and troubleshooting new equipment more challenging.
Age UK has highlighted the need for providers to communicate clearly with customers and ensure that people who require additional assistance receive suitable support. Providers should contact customers ahead of their planned migration and explain what the change means for their particular service. <Cite refs={[“turn354667search15″,”turn354667news6”]}/>
The process should not leave people feeling that they must understand complicated technology without assistance.
Family members and carers can also play a useful role by helping older relatives contact their providers, checking whether their equipment is compatible and ensuring that emergency arrangements are in place.
However, responsibility should not fall entirely on families. Telecommunications companies must identify customers who need additional support and make reasonable arrangements to help them through the transition.
Millions of Essential Devices May Need Checking
The telephone network supports more than ordinary conversations. Some households use their landlines to operate personal alarms, medical monitoring equipment, security systems and other connected devices.
Personal emergency alarms are particularly important for people who live alone or face an increased risk of falling. These systems can allow a person to request assistance by pressing a button or activating a sensor.
If such equipment depends on an old analogue connection, switching to a digital line without checking compatibility could interrupt an important safety service.
The government and telecommunications industry have therefore emphasised the need to identify telecare users and ensure that their equipment continues working safely after migration. Guidance calls on customers to inform both their telephone provider and their device supplier before the change. <Cite refs={[“turn354667news7″,”turn354667search16”]}/>
Households should not disconnect or replace a working emergency alarm without first obtaining advice from the relevant supplier.
The same principle applies to burglar alarms, lift communication systems and other equipment connected to telephone lines. Businesses and property managers may also need to review systems that depend on the traditional network.
A successful switchover requires more than establishing a working phone connection. It must ensure that the services people rely on remain functional.
Will Households Have to Pay for the Change?
The cost will depend on the provider, the existing package and the equipment required.
Some customers may only need to connect their existing telephone to a router or use an adapter supplied by their provider. Others may need new equipment or an alternative broadband service.
Customers should contact their provider to establish whether installation or equipment charges apply to their particular circumstances. They should also ask whether their current telephone package will change and whether the new arrangement affects their monthly bill.
Anyone receiving an unexpected request for payment should verify it directly with their provider before handing over money or personal information.
Citizens Advice warns that customers should be alert to scams exploiting the landline transition. A caller or message claiming to offer an urgent upgrade should not automatically be trusted, particularly if it asks for bank details or pressures the recipient to pay. <Cite refs={[“turn354667search16”]}/>
The safest approach is to contact the provider using an established telephone number or official website.
What Happens If You Do Nothing Before January?
The scheduled deadline is 31 January 2027 for the traditional Openreach network. Customers who remain on the old system should not assume their existing service will continue indefinitely.
According to Openreach, some customers who have not migrated may be placed on a temporary Emergency Voice and Access Continuity service, where applicable. This is intended to preserve basic voice calling for a limited period, but it does not necessarily support all the features available through a normal telephone service. Some customers could experience a loss of service if they fail to make the necessary arrangements. <Cite refs={[“turn354667search0″,”turn354667search1”]}/>
Waiting until the last moment could also make it harder to resolve problems involving broadband availability, specialist devices or installation appointments.
Customers who need additional assistance should therefore contact their provider well before the deadline.
Those who live in flats or rural properties where full-fibre broadband is unavailable should not assume that they have no options. Providers may be able to offer alternative digital connections, depending on local infrastructure.
The appropriate solution will vary from one household to another.
A Historic Change for British Communications
The transition marks the end of an era in British telecommunications. The telephone network that connected generations of households is giving way to a system designed around digital communications.
For many people, the upgrade will bring little disruption to their daily lives. They will continue using their home phones, keeping familiar numbers and speaking to friends and family as before.
For others, particularly people who depend on landlines for safety or live in areas with poor mobile coverage, the transition demands more careful preparation.
The responsibility is shared between customers, service providers and the organisations responsible for protecting vulnerable people. Clear information, reliable installation and suitable backup arrangements will be essential.
As January 2027 approaches, households should check whether they are affected, contact their provider and identify any equipment that might need special attention.
The most important message is that Britain’s traditional landline network is changing, not that everyone must stop using a home telephone. With the right preparation and support, households can continue to benefit from landline services while the technology behind them moves into a new era.
