CityFibre Business Connectivity UK: Full Fibre for Modern Business

CityFibre in the UK: Why It Matters for Business

Traditional copper and part-fibre internet connections are no longer enough in a cloud-first, distributed workplace environment. Businesses today demand ultra-fast, highly reliable, symmetrical connectivity for applications from MS Teams to MDR cybersecurity to remote work. CityFibre is the UK’s largest alternative full fibre network dedicated to next-generation business and public sector connectivity.

By investing billions in new networks, CityFibre is rolling out full fibre infrastructure in over 285 towns and cities, aiming for 30% nationwide coverage. Its purpose-built network separates business and residential traffic, creating robust SLAs and lower contention ratios. Delivered by partners like AMVIA, CityFibre business packages offer speeds up to 10Gbps, ultra-low latency, and enterprise service guarantees.

CityFibre vs. Other Options: The Differences

Compared to Openreach and Virgin Media, CityFibre’s network is purpose-built for business, not a retrofitted consumer broadband grid. Unlike FTTC or G.fast, true full fibre to the premises (FTTP) eliminates reliability bottlenecks caused by legacy copper, allowing consistent performance at all hours. Business-grade SLAs cover speed, uptime, engineer response, and mean time to repair (MTTR), with penalties for failure.

CityFibre offers symmetrical speeds: upload is as fast as download. This is essential for businesses using large cloud platforms, video meetings, VoIP, or off-site backup/disaster recovery. Options include dedicated leased lines for ultimate reliability—see leased line pricing—and cost-effective shared fibre for SME budgets.

How CityFibre Improves Modern IT Strategy

  • Cloud-first business: Modern platforms like Microsoft 365, Salesforce, and Unified Comms require ultra-reliable bandwidth and low latency to avoid dropped calls and slow applications.
  • Distributed workforce: Hybrid and remote workers need smooth, secure VPN/MDR connectivity from anywhere. See remote worker security for details.
  • Cybersecurity operations: True fibre enables real-time MDR, SOC monitoring, cloud SIEM and endpoint threat detection uninterrupted by “slowdowns.” Managed Detection and Response delivered over full fibre is far more effective.
  • Resilience and scaling: Full fibre underpins failover, DR, rapid scaling, and burst bandwidth for business growth and compliance needs.

Implementation: What Businesses Should Do

  1. Check availability: Use AMVIA’s CityFibre checker or call for pre-qualification in your area.
  2. Review options: Assess leased line, FTTP, and shared fibre packages depending on network needs, budget, SLAs, and resilience.
  3. Plan migration: Ensure business-critical apps can transition smoothly, with resilience and failover tested pre-cutover. Include cybersecurity upgrades alongside bandwidth upgrades.

Common Connectivity Failures and How CityFibre Solves Them

Symmetry Gaps

Old FTTC or hybrid fibre connections have slow upload, causing cloud file sync and VoIP instability. CityFibre’s full fibre is symmetrical: upload equals download. Upgrades solve poor video quality and slow backups.

Contention and SLAs

Low-cost fibre broadband can get congested at peak times or miss uptime/SLA guarantees. CityFibre’s networks are built for business, separated from consumer broadband, and with strict SLAs on uptime and support.

Missed Growth Opportunities

SLOW or unreliable networks prevent cloud migrations, delay MDR/security projects, and block digital transformation. CityFibre’s scalable fibre adapts to growth and tech changes.

Board-Level and IT Leadership Considerations

CityFibre’s full fibre is not just an IT upgrade—it is the strategic infrastructure for board-level digital and security initiatives. Leadership should track:

  • Uptime and SLA adherence
  • Cost per Mbps of resilient fibre
  • Support for digital transformation initiatives
  • Impact on hybrid work, security, and future scalability

The Path Forward

CityFibre is transforming UK business broadband. For most firms ready to invest in modern cloud, VoIP, security, and hybrid work, moving to full fibre is non-negotiable. The upgrade cost is modest compared to the boost in performance, resilience, and security. Firms relying on outdated copper should ask: Is our network ready for today’s cloud and security?
