Introduction

By 2025, telecom providers across the UK will permanently switch off support for analogue networks. This includes:

• The withdrawal of traditional copper-based telephone lines
• The replacement of PSTN and ISDN systems with all-digital alternatives
• The decommissioning of 2G and 3G mobile networks

For businesses, this isn’t just a technology upgrade — it’s a fundamental change in how communication is delivered. The analogue switch-off will affect millions of people and organisations, making it essential to plan ahead.

What Does the Analogue Switch-Off Mean?

The Public Switched Telephone Network (PSTN), which has supported UK communications for decades, will be retired. Voice calls, broadband, and many legacy services currently running on copper lines will no longer function.

This change is part of a broader digital transformation aimed at:

• Improving speed and reliability of communications
• Supporting modern services such as VoIP and fibre broadband
• Reducing maintenance costs and environmental impact of outdated networks

How Will This Affect Businesses?

For SMEs, the switch-off brings both risks and opportunities.

Risks of not preparing:

• Loss of phone service if reliant on analogue lines
• Disruption to alarms, payment systems, and fax machines still tied to copper networks
• Increased costs if emergency replacements are needed at short notice

Opportunities of preparing early:

• Transition to modern, cloud-based communication systems
• Improve flexibility with remote and hybrid working solutions
• Benefit from lower, predictable costs with VoIP
• Increase resilience and security with digital-first technology

Why VoIP Is the Future of Business Communication

Voice over Internet Protocol (VoIP) uses your broadband connection to deliver phone calls and unified communication services. Unlike analogue lines, VoIP is:

• Scalable – Add or remove users easily as your business grows
• Cost-effective – Predictable monthly costs without line rental fees
• Feature-rich – Video conferencing, call routing, voicemail-to-email, and more
• Flexible – Staff can work from the office, home, or on the move seamlessly
