Landlines in the UK are going digital. The existing analogue technology (the PSTN - Public Switched Telephone Network) which has supported phone and broadband services for decades is being retired and switched off.

The good news is the landline is here to stay.  By the end of January 2027, the vast majority of customers will be provided with a broadband line, making calls the same as they do today,  but using ‘Voice over IP’ technology that uses an internet connection. 

Digital landlines will be easier to maintain and will underpin many of the new digital services for homes and businesses, providing a better service for customers.

The switch from analogue to digital landlines  has already started in many countries including Germany, France, Australia and Japan and is a key step towards preparing the country for a Full Fibre future, in support of the UK Government’s gigabit connectivity ambitions. 

Together with Government, Ofcom, telecoms providers, charity partners and key industry groups, BT is working hard to ensure that everyone knows about the change, how they will be impacted and what they need to do as a result.

Home customers

Digital Voice is BT’s new home phone service, delivered over a broadband connection.

For most customers, the switch to Digital Voice will be as simple as connecting your home phone handset to a router rather than the phone socket on the wall.

Following successful trials in Salisbury and Mildenhall, BT is raising awareness about the switch to Digital Voice on a region-by-region basis.

BT’s regional awareness raising is being supported by local general awareness communications, local events and advertising campaigns to help customers understand the simple steps required to make the move to Digital Voice.

Customers will be contacted at least four weeks in advance before making the switch, to ensure they are ready to move to Digital Voice.

Business customers

Alongside traditional phone services, the PSTN supports everything from alarm systems, and traffic lights to ATMs. Customers who have devices connected to their landline, will need to check with the manufacturer or service provider that any equipment they use will still work on a digital landline. 

At BT, our expert teams are working with business customers, large and small, helping them to embrace modern, digital alternatives.
