The 2025 PSTN Switch Off: Is Your Business Prepared?


In the rapidly evolving landscape of telecommunications, the upcoming switch-off of the Public Switched Telephone Network (PSTN) in 2025 looms large, presenting both challenges and opportunities for businesses across the UK. However, recent findings suggest that a significant amount of businesses, particularly smaller businesses and micro-entities, are alarmingly unaware of the looming technological shift and the potential impact on their business that it may bring. In this blog post, we delve into the critical aspects surrounding the PSTN switch-off, its implications, and the imperative need for businesses to take proactive measures to ensure continuity and future-proof their operations.

Lack of Awareness and Implications: According to recent statistics, nearly one-third of UK businesses remain oblivious to the impending PSTN switch-off. In Wales the figure is worse, with awareness at just 29%. This lack of awareness poses a significant risk, potentially leading to severe disruptions in business operations and even the loss of clients, not to mention the prospect of increased costs due to a late, rushed transition.

Alarmingly, only 54% of those directly impacted by the switch-off are conscious of it, indicating a glaring gap in preparedness, particularly among vulnerable businesses. The implications extend beyond telecommunications, affecting essential operational functions such as customer support, order processing, payment processing, security systems and internal communications.

Vulnerability of Small Businesses: Small businesses, in particular, are at a heightened risk due to their dependency on PSTN for vital operational functions. The statistics paint a concerning picture, with a staggering 88% of micro-businesses yet to start an audit of their PSTN lines and develop a migration plan. The lack of preparedness among small enterprises amplifies the potential for operational interruptions and financial losses, highlighting the urgent need for action. With 69% of businesses who use PSTN for voice communications relying on it for customer support, and 59% relying on it for taking orders or bookings, loss of service could be catastrophic.

Challenges and Inaction: Even among businesses aware of the switch-off, challenges persist, with a significant percentage yet to complete essential migration tasks. Inaction among businesses, especially small enterprises, poses dire consequences, including business closure, loss of customer trust, and financial setbacks. Activities such as auditing PSTN lines, researching alternatives, and formulating migration plans are crucial steps towards ensuring business continuity. With PSTN supporting many vital business functions such as payment terminals, alarm systems and elevators the impact of inaction will be great.

Urgency of Action: With the switch-off date drawing closer, businesses cannot afford to delay preparations any further. It is imperative for companies to expand their risk assessments to include all operations dependent on PSTN and develop comprehensive contingency plans. Speeding up the adoption of alternative technologies and allocating resources to migration planning are vital to mitigating risks and ensuring a smooth transition, not to mention avoiding the financial consequences of leaving it too late. Businesses not yet even ‘in the queue’ for solutions may well find themselves in a last-minute rush for services which will overwhelm systems if too many migrations are attempted at once.

As the 2025 PSTN switch-off approaches, businesses must heed the call to action and prioritise preparations to safeguard their operations. The consequences of inaction are too significant to ignore, especially for small enterprises with limited resources. By taking proactive steps now, businesses can not only ensure continuity but also unlock the benefits of digital, future-proof communications.
