The UK’s move towards an all-IP future is no longer a distant milestone — it’s now a strategic priority for businesses preparing for the 2025 PSTN switch-off and the wider shift to digital-first operations. By 2026, most organisations will be running voice, data, payments, and customer communications over IP networks rather than legacy copper lines.
This shift isn’t happening because technology is becoming “flashier”. It’s happening because small and mid-sized businesses can no longer operate efficiently on ageing fixed-line infrastructure — especially as retail, e-commerce, hospitality, field services, and hybrid workplaces depend heavily on reliable connectivity.
With VoIP phone systems for businesses, fibre broadband, and mobile-first tools accelerating across the UK, companies that prepare early will see smoother operations, lower communication costs, and greater resilience than those waiting until the final months of the transition.
This is where Aritel’s telecom and digital solutions stand out.

The UK’s Copper Networks Are Reaching End-of-Life
The traditional Public Switched Telephone Network (PSTN) is scheduled for withdrawal across the UK by 2025 or 2026 — a confirmed nationwide transition supported by industry-wide announcements and regulatory updates from Ofcom.
This change affects every organisation that still depends on copper-based services, including:
- Traditional landline telephony
- Analogue and on-premise PBX telephone systems
- Fax machines
- Lift/emergency lines and alarm signalling
- ADSL/FTTC broadband delivered over copper
- Payment terminals and EPOS setups that route transactions via PSTN
- Legacy card machines using dial-up connectivity
Even without the formal withdrawal, it has become increasingly clear that copper networks can no longer meet the performance, resilience, or digital needs of modern UK businesses — making the shift to all-IP services both inevitable and beneficial.
Market Data Shows the Decline of Fixed Voice
Verified telecoms data tells a consistent story. Fixed-line usage is declining sharply as digital alternatives continue to gain traction.
In Q2 2025, fixed voice revenues dropped by 14.1% year-on-year to £1.04 billion as users moved to digital alternatives. This shift hits retailers particularly hard because they rely on customer-facing voice services. As consumers and staff transition to IP-based platforms, legacy systems are unable to support modern communication patterns.
Why 2026 Will Be the “All-IP Normal”?
Several converging trends are making 2026 the turning point for UK businesses:
-
Fibre Coverage Growth
The UK Government’s Project Gigabit and provider rollouts continue to accelerate FTTP coverage. As of 2025, full-fibre availability has passed 79% of UK premises. By 2026, most business postcodes — including high streets and industrial estates — will have an FTTP option.
-
VoIP Adoption Increasing
VoIP adoption among UK SMEs continues to grow due to reduced expenses and remote-friendly features that support remote work. The increasing dependence on cloud-based applications & hybrid arrangements has prompted businesses to replace older phone setups for more flexible, IP-based alternatives. With more services moving online now, SMEs are placing importance on telephone systems that integrate seamlessly with:
- Collaboration tools
- CRM platforms
- Mobile devices
-
AI and Automation Tools Require Stable IP Networks
Retailers, healthcare providers, educators, and service industries are all utilising analytics, automation, and digital processes that require fast and dependable internet connections. These tools cannot run effectively on PSTN-based systems. As AI-driven operations become mainstream, businesses need networks that support real-time data processing — a capability that legacy copper lines were never designed to handle.
-
Mobile Networks Are Now Core to Business Continuity
With 4G/5G reliability improving, SIM-based backup connectivity is quickly becoming standard. This convergence makes 2026 the year when IP becomes the default — not an upgrade. Many SMEs now pair fibre with 4G/5G failover to avoid downtime, making mobile-first resilience a fundamental part of modern connectivity planning.

What Does The Industry Transition Mean for UK Retailers, Small Businesses, & Service Providers?
An all-IP environment gives organisations a foundation that is faster, more resilient, and future-proof by design. Key advantages include:
-
More Reliable Communications
Voice and data networks leveraging IP technology substantially reduce interruptions and call performance problems, thereby ensuring smoother day-to-day operations. Businesses can expect:
- Fewer dropped calls and less interference compared to legacy copper lines.
- Capability to handle numerous concurrent connections, promoting smooth collaboration across teams.
- Enhanced consistency for remote and hybrid working setups, keeping staff connected wherever they are.
-
Lower Overall Connectivity Costs
Consolidating voice & data into a single infrastructure can reduce costs & simplify management & administration. Key advantages include:
- Elimination of separate landline and broadband subscriptions.
- Lower IT maintenance costs by managing voice & data under one provider.
- Reduced investment in legacy hardware, saving both upfront & ongoing expenses.
-
Better Performance for Cloud Systems
All IP-based networks offer ample data capacity & minimal delay connections, which are essential for cloud services to function optimally. Benefits include:
- Smooth video conferencing/cloud POS/real-time collaboration even during peak hours.
- Efficient handling of data-heavy applications like inventory management & analytics.
- Faster access to cloud-hosted CRMs/booking platforms improves operational efficiency.
-
Faster Customer Response Times
With VoIP, mobile backup, and intelligent routing, businesses can respond to customers quickly — in-store/online/remotely. This enables:
- Automated call routing to ensure queries reach the right department or agent.
- Reduced response times for online & voice-based customer support.
- Enhanced service continuity even during busy periods or network interruptions.
-
Secure, Compliant Infrastructure
IP networks support modern security protocols & compliance measures that legacy systems cannot match. Benefits include:
- Stronger encryption & automated updates to reduce cyber risk.
- Centralised data monitoring to maintain GDPR compliance.
- Enhanced protection for payments, customer records, and sensitive internal communications.
-
Tools Ready for AI and Automation
The stability of all-IP connectivity allows businesses to harness AI and automation effectively. This provides:
- Support for predictive analytics to optimise inventory, staffing, and marketing decisions.
- AI-driven customer service tools, including virtual assistants, automated alerts, and workflow automation.
- Integration with collaboration platforms and cloud-based tools for smarter, more efficient operations.
In short, running any operation on copper networks will no longer be sustainable in 2026, either technically or commercially. Migration isn’t just an upgrade — it’s a requirement for staying competitive.
