Openreach is warning that time is running out for UK businesses still relying on copper telephone networks, which are due to be switched off permanently in January 2027. Many business owners don’t realise how significantly this change could affect their daily operations.
As the operator that manages most of the UK’s telecoms infrastructure, Openreach stresses this is not a simple upgrade you can ignore. When the traditional Public Switched Telephone Network (PSTN) is switched off, any device or service that depends on it will stop working.
Think about what happens if payment terminals lose their connection, security alarms stop reporting, or office phones that customers depend on suddenly go silent. These failures are more than inconvenient — they can cause real financial and reputational damage to unprepared businesses.
James Lilley, Director of All-IP at Openreach, said the nationwide move to an all-IP network has been a major project with a focus on protecting vulnerable users. Now that those safeguards are in place, the deadline is set and businesses must act. “It’s time for businesses to move off legacy infrastructure. The digital world won’t wait. Every day of delay increases the risk of disruption, higher costs, and missed opportunities,” he warned.
For many UK business owners the shift from copper to digital networks may seem daunting. What needs changing, and where do you start? Openreach recommends a clear three-step approach to make the transition manageable:
- Inventory: Walk through your premises and list everything that plugs into a phone socket. Old fax machines, alarm systems, card payment terminals and legacy office phones are all potential points of failure.
- Test: Use available testing services to check whether your existing equipment will work with digital networks. Openreach and other providers run test labs where businesses can verify compatibility before committing to changes.
- Switch: Contact your phone or internet provider to arrange the migration to digital lines. Providers can recommend the right solution for your business, whether that means a simple adapter, a firmware update, or full equipment replacement.
Some businesses delay because they fear disruption or expense, but postponing often increases costs. Some service providers are already closing older networks sooner than the national deadline — in some cases as early as December 2025 — so the closer organisations get to the cutoff dates, the harder it will be to book installation and support.
Digital networks offer clear benefits: better call quality, more reliable connections, and features that were not possible on analogue systems. Migrating now not only avoids interruption but also enables improved communications and new capabilities for your business.
This migration away from copper isn’t unique to the UK. Countries around the world are moving to digital networks because running both analogue and digital infrastructures is costly and inefficient. The future is digital, whether businesses are prepared or not.
Local retailers often worry about card payment terminals. Imagine a busy Saturday morning at a bakery when card machines stop working, or a small security company whose alarm panels can no longer reach monitoring centres—both are realistic risks if systems remain tied to PSTN lines.
Fortunately, solutions exist for most scenarios. Some devices will continue to function with an adapter or a simple configuration change; others may require replacement. The important point is to determine which applies to your equipment now rather than waiting until failure forces hasty decisions.
Businesses that plan ahead can choose how and when to upgrade. Those that leave migration to the last minute often face limited options, longer wait times, and higher costs. Telecoms experts predict the final months before January 2027 will see a scramble as organisations rush to complete their moves.
If you’re unsure where to start, the first step is straightforward: call your current phone or internet provider. They can explain your options and help you plan a migration to digital services. Openreach also provides guidance and resources for businesses with non-standard setups or special requirements.
The message is simple: this is not a question of if but when. The century-old copper network is being retired, and businesses that ignore the change risk sudden disconnection in a world that has already moved on.
