By the end of 2026, the UKโs traditional phone network (PSTN & ISDN) will be switched off for good. That might sound like a distant technical change, but for many businesses, it will have a direct impact on daily operations.

โ
Avoid lastโminute disruption
Leaving it too late risks rushed installs, limited supplier availability and potential downtime to your phone services.
โ
Future proof your communications
Modern cloud and VoIP systems arenโt just replacements, they offer flexibility, resilience, and features PSTN simply canโt support.
โ
Better costs, better control
Reduced line rental, easier scalability, and smarter call handling can lower costs while improving customer experience.
โ
Time to test and transition properly
Upgrading early lets your team adapt gradually, with training, testing and optimisation before the switch off deadline.

When PSTN is switched off:
โ Desk phones may stop working
โ Calls to and from customers could fail
โ Alarm systems, lifts, EPOS, and broadband services using PSTN may be affected
โ Your business risks becoming unreachable during working hours
In short: no phone service, lost calls, lost sales and frustrated customers.
Upgrading now isnโt about panic, itโs about control, continuity and opportunity.
Businesses that move early gain a smoother transition and a communications platform that supports how they work today and tomorrow.
