voice /pstn switch off

Legacy Voice services are ending - act now to protect your business

The UK phone network is changing. Traditional landline services are being retired and replaced with modern digital alternatives that run over broadband. This change will affect every business using legacy phone lines or systems. But with early planning, you can stay connected and make the switch smoothly.

Key Deadlines

Dec 2025

As of December 2025, Openreach only needs to provide 90 days’ notice before disconnecting a line. That means businesses need to be ready.

Jan 2027

The full PSTN and ISDN switch-off will take place.

Any remaining services on the network will stop working.

Risks to your business if you delay

If you’ve not yet made the move to a modern phone service, the risk of escalating prices and losing access to your services is now very real.

Find out why you need to make the switch now on our blog.

Service disruption: If you don’t move to digital services in time, your business phones may stop working. That could mean missed calls, downtime and lost sales.

Operational risk: Shorter notice periods mean less time to prepare. Leaving it late could lead to rushed, unplanned changes that cost more and cause disruption.

Rising costs: As the switch-off approaches, the price of maintaining legacy services will increase. Engineers will be in high demand, and availability will be limited. Planning now helps you avoid these extra costs.

Security vulnerabilities: Old systems are more exposed to cyber threats. Moving to IP-based solutions gives you stronger protection and better control.

Competitiveness: Businesses that delay risk being left behind. Those already using IP-based phone systems benefit from flexibility, advanced features and lower running costs.
