The UK’s PSTN network will switch off in 2027

BT plans to discontinue ISDN and PSTN services in 2027. But what is going on, and how will the switch-off affect your business?

The plan to withdraw BT and Openreach’s old copper-based PTSN analogue line services, which was due to complete by December 2025, has been delayed until 31st January 2027 in order to give broadband, telecoms providers and consumers more time to adapt.

BT’s press release said this:

"Following the industry-wide pause to non-voluntary migrations in December 2023, we now expect to have migrated all customers off the PSTN by the end of January 2027, allowing us to align the programme with full fibre broadband customer upgrades where available."

What’s happening?

UK telecoms provider BT is moving all their customers from the old analogue public switched telephone network (PSTN) to a fully digital network. They've already started. They plan to have moved everyone over before Openreach stop the PSTN (and ISDN) service in 2027.

By then, every phone line in the UK will be digitalrouting calls over IP (Internet Protocol) rather than the traditional PSTN.

What will be affected?

A range of services will be affected by the switch off, including:

  • Phone lines and their numbers
  • ADSL & FTTC broadband internet services
  • Door entry systems & CCTV
  • Burglar, fire & panic alarms
  • Fax machines
  • Emergency phones & lift lines
  • EPOS terminals & card machines

What do I need to do?

If you currently have a traditional ISDN (Integrated Services Digital Network) or PSTN (Public Switched Telephone Network) based system, now is a good point to look into the alternative.

Although there is plenty of time until 2027 rolls around, it’s best to plan ahead and you may actually find you want to migrate sooner rather than later after finding out all of the benefits the replacement internet-based systems have to offer your business.

Why is this happening?

The existing network is outdated and difficult to maintain. The PSTN, being a mostly 20th-century technology, is becoming out of step with the demands of 21st-century communications.

People are shifting away from traditional phone use and toward mobile and internet communications. We all have higher expectations of current phone services than conventional technology can provide. The solution is digital.

Openreach is busily rolling out full fibre network (fibre to the premises or FTTP) in phases across the UK. By September 2023, BT will no longer sell traditional phone lines throughout the UK.
