What’s the Big Switch Off all about?

Things are changing in the world of telecoms and your existing telephony solution might become obsolete soon. January 2027 will see the end on the UK Telephone Network as we know it (delayed from September 2025).

BT Openreach has announced it intends to switch off traditional landlines. This is commonly referred to as the Public Switch Telephone Network (PSTN) and Integrated Services Digital Network (ISDN) switch off.

Openreach has already stopped selling many well-known communications services at hundreds of exchanges across the country. Which means that your communications strategy could be in danger and we are seeing the costs of other associated services rising sharply.

What you need to do

It’s time to start planning! The longer you wait, the more opportunities you’re missing out on and costs will rise rapidly.

In January 2027, the Public Switched Telephone Network (PSTN) is being switched off by BT Openreach, which means everyone, including businesses, currently using PSTN-based services will need to move to another service before then.

What other services will be affected by the PSTN Switch Off?

The phaseout will include ISDN networks since these also run on traditional telephone lines. Everything else that uses your old phone network will be affected by the switch-off too. This includes door entry systems, CCTVs, fax machines, PSTN alarm systems and even electronic point-of-sale (EPOS) machines.

What are your alternatives and new technologies?

Telephone Systems

Voice over Internet Protocol (VoIP) is a digital phone solution that transmits voice calls and data using an internet connection (whether it is FTTP or SoGEA). VoIP core networks will replace all legacy PSTN services as part of the switch off. The flexibility and savings with VoIP are endless.

Connectivity

FTTP (Fibre to the Premises) is a type of broadband, supplied by fibre optic cables from your local internet exchange directly to your premises. SoGEA is another option that uses the existing fibre/copper network, where fibre to the premises (FTTP) is not yet available. Ethernet and Leased Lines are also options.
