The Big Switch Off

As we approach the end of 2025, significant changes that affect us all in some way are on the horizon for businesses as Openreach, a subsidiary of British Telecom, bids farewell to the Public Switched Telephone Network (PSTN) and introduces a ‘full fibre’ network.

This page is designed to give you access to useful resources and information about the 2025 Switch Off, please contact us to take advantage of a free-of-charge review of your current telephone line services and recommendations to avoid any problems you could face otherwise.

The PSTN switch-off, driven by Openreach, is the shutdown of the Public Switched Telephone Network by the end of 2025.

The PSTN switch-off signifies the retirement of the traditional telephone network that has been in use for over a century. Openreach is moving towards a more advanced ‘full fibre’ network, a change that impacts how businesses handle their communication infrastructure.

This shift is driven by the need for more efficient and modern communication technologies. The traditional PSTN, designed for analogue telephone calls, is coming to end-of-life.

The PSTN switch-off has implications for businesses relying on traditional phone lines. It means the end of Wholesale Line Rental (WLR) products, including ISDN and analogue lines. If your business is still using these services, it’s essential to adapt to the changes to ensure seamless communication.

Services Affected by the 2025 PSTN Switch-Off

Understanding the impact on these services is crucial for businesses to proactively address the upcoming changes, ensuring uninterrupted communication and adopting more advanced, future-proof solutions.

Traditional Phone Lines (ISDN and Analog):

Wholesale Line Rental (WLR) Products:

WLR products, including ISDN and analogue lines, will reach the end of their life by December 2025.

Fibre to the Cabinet (FTTC) Broadband:

FTTC broadband, which uses a mix of fibre optics and copper wire, will see changes as it is closely tied to the traditional PSTN infrastructure.

Traditional Private Branch Exchange (PBX) Systems:

On-site PBX systems, managing internal and external calls, will face limitations compared to more modern solutions.

Copper-Based Services:

Services relying on copper infrastructure, which includes many traditional telecommunication setups, will be affected.

Alarm Systems and Other Embedded Networks:

Traditional telephone networks embedded in services like alarm systems will be impacted, requiring adaptation to new technologies.

Existing Legacy Broadband Technologies (e.g., FTTC & ADSL):

Older broadband technologies, such as Asymmetric Digital Subscriber Line (ADSL) & Fibre To The Cabinet (FTTC), may see changes as the telecommunications landscape evolves.
