The Great British Switch Off: Six reasons why you shouldn’t wait

As the January 2027 deadline for the Great British Switch Off (GBSO) approaches, you may be tempted to wait until the last moment to migrate from your old phone system. But waiting to act could result in disruptions, rising costs, and security vulnerabilities – all of which could seriously impact your business.

Here are six reasons why it’s crucial to make the move now and future-proof your business communications.

1. Don’t get caught out: Service disruption is serious

One of the greatest risks of waiting too long to migrate your voice service to a modern digital solution is service disruption. By the time the Great British Switch Off is done, any businesses still using PSTN or ISDN phone services risk losing their connectivity altogether. Imagine not being able to reach customers because your phones suddenly stop working.

But it’s not just that moment in a couple of years that you need to be aware of. Faults on copper networks – which the PSTN relies on – are already increasing, with businesses facing longer wait times for repairs. And regrades and upgrades are already impossible in many regions. Transitioning now ensures you stay connected without interruptions.

2. The hidden costs of delay: Don’t let prices spiral

Waiting to migrate until the last minute may seem cost-effective, but it could lead to higher migration costs. As demand for engineers and resources increases closer to the deadline, you could face steep costs and limited availability of services.

Openreach, the UK’s digital infrastructure provider, is also expected to hike rental prices on legacy technology to incentivise earlier migrations. And that makes for a simple equation: the longer you wait, the more you’ll pay.

Planning your transition now can help spread costs more comfortably and avoid the price surge that will come with a last-minute rush.

3: Security vulnerabilities: Legacy systems, modern risks

Older, copper-based telephone systems lack the advanced security features of their modern digital replacements. This can leave businesses more exposed to cybersecurity threats such as data breaches or hacking. Upgrading to secure IP-based solutions, like Zen’s CloudComms, brings built-in encryption, enhanced business continuity, and other robust security features.

By acting now, you’re not just upgrading your phone system – you’re protecting your business from cyberattacks.

4. Lost competitive edge: Adapting to a modern workplace

Competitors who make the switch sooner will benefit from more flexible, integrated communications systems, giving them a head start. Modern communications systems offer features like remote working capabilities, integration with collaboration tools, and future-proofed technologies that support the evolving needs of businesses.

Don’t let your competitors get a head start. By preparing early, you can avoid being left behind.

5. Operational risk: The clock is ticking

The 90-day notice period for line termination starting in December 2025 means the clock is ticking faster than ever. Delaying decisions could force your business into a rushed migration if you’re suddenly given notice. This can increase the risk of unplanned outages, disruption, and ending up with a poor solution.

But early planning ensures a smooth, stress-free transition to the best setup for your business.

6. Future-proof your business: Preparing for success

Switching to IP-based communication systems isn’t just about upgrading your phones – it’s about making sure your business is ready for the future. Modern unified communications systems are scalable and adaptable, allowing you to easily integrate new technologies like AI, 5G, or advanced collaboration tools.

By migrating now, you can ensure your communication setup is ready for future growth and innovation.
