What's happening?
The Public Switched Telephone Network (PSTN) will close by 31 January 2027.
By then, every phone line in the UK will have moved to a fully digital network that uses Internet Protocol (IP) across a fibre-based service.
This won’t just affect voice services, it may also mean you need to upgrade your broadband.
Any equipment that currently uses the PSTN will stop working: alarms, EPOS machines, door entry systems, CCTV, faxes, and so on.
The Integrated Services Digital Network (ISDN) will also stop working.
Why’s this happening?
Our current network is old and difficult to maintain. As an essentially 20th century technology, the PSTN is increasingly out of kilter with the demands of 21st century communications.
Traditional phone usage is changing everywhere as people switch to mobile and internet communications. We all expect much more from modern phone services than the traditional technologies can deliver.
Digital is the answer.
What does this mean for me?
Before the PTSN closes, you’ll need to move from PSTN to the latest IP technology.
To help make that possible, Openreach is busy rolling out the full fibre network (fibre to the premises or FTTP) in phases across the UK.
Openreach’s roadmap to a full fibre network
To make the transition as seamless as possible, Openreach is enabling full fibre exchanges in a phased approach across the UK. Openreach will add new exchanges to the rollout plan each quarter.
You can read more about the switch-off on Openreach’s website. In the Resources section, you can download the list of exchanges Openreach has announced so far.

The PSTN stop sell
We’ve stopped selling traditional phone lines in all exchange areas as of September 2023. The PSTN stop sell means you can no longer purchase legacy voice or broadband services.
The PSTN stop sell is a major milestone in the UK’s transition to more advanced and efficient communication technologies. By upgrading to IP solutions, your business can benefit from enhanced features, improved scalability, and cost savings.
With the stop sell in place, it's important to plan ahead and begin exploring IP alternatives sooner rather than later. Our team will guide you through the transition process to make sure you have a seamless migration.
