Openreach is urging UK businesses to accelerate their transition to digital networks ahead of the January 2027 PSTN switch-off deadline. The company warns that firms still relying on legacy systems risk significant operational disruptions and financial setbacks as outdated infrastructure is decommissioned. Businesses are advised to review, test, and switch to all-IP solutions promptly.
The urgent call for digital migration
Openreach has issued a strong appeal to UK businesses, urging them to expedite their shift to digital networks. With the January 2027 Public Switched Telephone Network (PSTN) switch-off deadline rapidly approaching, the company stresses that businesses and communication service providers (CSPs) still dependent on older systems face considerable risks.
Risks of delaying the switchover
Continuing to rely on outdated PSTN infrastructure poses threats to both operational efficiency and financial stability. As legacy networks are phased out, critical systems such as payment terminals, security alarms, ISDN systems, and traditional landline phones will cease to function. This could lead to widespread disruptions for unprepared businesses.
Openreach’s guidance for businesses
James Lilley, Director of All-IP at Openreach, emphasised the importance of immediate action. He stated that the nationwide transition to an all-IP network is a monumental undertaking, with vulnerable users’ protection being a key priority. Now that these needs have been addressed, the deadline is firm.
Lilley urged businesses to "unchain their networks from legacy infrastructure" as the digital world will not wait for those who delay. He warned that every day of procrastination increases the risk of:
- Disruptions
- Higher costs
- Missed opportunities
Steps to a smooth transition
Openreach has outlined a clear three-step process for businesses to manage the transition:
- Review: Identify all connectivity equipment still reliant on PSTN.
- Test: Utilise Openreach’s free test labs to ensure compatibility with all-IP networks.
- Switch: Migrate to a digital solution as soon as possible.
The company also provides various resources, including support for complex cases and temporary solutions, to assist businesses. Those uncertain about the impact of the switch-off are advised to contact their service provider.
The looming deadline and its implications
While the official PSTN switch-off deadline is January 2027, some CSPs have earlier cut-off dates, with some as early as December 2025. Openreach warns that businesses that delay their migration will face:
- Mounting costs
- Increased security risks
- Missed growth opportunities
Openreach strongly recommends that all businesses make the move now to harness the full potential of next-generation communication technologies.
