CityFibre Business Connectivity: Why Full Fibre Matters for UK Businesses in 2026

CityFibre delivers full fibre business connectivity with high speed, resilience, and nationwide expansion. Key upgrade for digital transformation.

CityFibre Business Connectivity: Why Full Fibre Matters for UK Businesses in 2026

CityFibre is the UK's largest independent full fibre network, delivering symmetrical gigabit speeds (up to 10Gbps) with enterprise SLAs and 99.9% uptime guarantees—essential for cloud-first operations, remote work, and real-time cybersecurity monitoring. Unlike consumer-focused broadband, CityFibre's purpose-built business network separates traffic, eliminates copper bottlenecks, and scales with your organisation as it grows.

What is CityFibre Business Connectivity?

CityFibre is full fibre directly to your premises—fibre end-to-end with no copper "last mile." This eliminates reliability bottlenecks that plague legacy FTTC or hybrid networks.

CityFibre's network now covers over 285 towns and cities across the UK, with ambitious targets for 30%+ nationwide coverage by 2027. Check CityFibre availability at your postcode to confirm service in your area.

CityFibre vs. Traditional Broadband: What's the Difference?

CityFibre Full Fibre (FTTP):

  • Symmetrical speeds (upload = download)
  • Up to 10Gbps available
  • 99.9% uptime SLA with automatic credits
  • Business-grade network separation (no residential traffic)
  • Sub-2-hour engineer response

Traditional FTTC + Copper:

  • Asymmetrical speeds (slow upload)
  • Shared bandwidth during peak hours
  • Best-effort SLA (manual claims required)
  • Shared consumer/business infrastructure
  • Standard response times (24–48 hours)

Result: CityFibre's full fibre delivers consistent performance whether it's peak hours or off-peak—critical for mission-critical applications.

Why Does Your Business Need Full Fibre Now?

Cloud-First Operations Demand Reliable Bandwidth

Modern platforms like Microsoft 365, Salesforce, and Slack require ultra-reliable, low-latency connections. Slow uploads cause cloud file sync delays. Poor connectivity drops VoIP calls mid-conversation. Real-time collaboration stutters.

To calculate your actual bandwidth requirements, try our VoIP Cost Savings Calculator—it factors in concurrent users, video conferencing, and cloud application load.

Distributed Workforce Requires Secure, Fast Access

Hybrid and remote workers need smooth, consistent VPN access from anywhere. FTTC's variable speeds create frustration and security risks (employees seek faster, less secure alternatives). Full fibre delivers consistent speeds whether working from office or home.

Real-Time Cybersecurity Operations Need Uninterrupted Connectivity

Managed Detection and Response (MDR), SOC monitoring, and cloud SIEM require 24/7 low-latency connectivity. Brief slowdowns can delay threat detection by minutes—costing organisations £thousands in incident response time.

Pair CityFibre with enterprise-grade cybersecurity services for maximum protection.

Resilience and Scaling Drive Business Growth

Full fibre underpins failover, disaster recovery, and rapid scaling. As your business grows, you scale bandwidth instantly—no infrastructure limitations.

  • Ideal for mission-critical operations
  • Fixed costs for budget certainty

Choose CityFibre if: You want gigabit speeds at reasonable cost with flexibility and automatic scaling.

Choose leased line if: You need guaranteed uncontended bandwidth and can commit 3+ years.

For detailed comparison, see our FTTP vs Leased Line guide.

What Business Problems Does CityFibre Solve?

Problem 1: Upload Speed Bottlenecks

FTTC has slow upload, causing cloud file sync delays and VoIP instability.

CityFibre delivers symmetrical speeds: your upload is as fast as download. A 300Mbps CityFibre line delivers 300Mbps upload AND download—solving cloud backup delays and video conferencing issues instantly.

Problem 2: Peak-Hour Contention

Shared broadband slows during peak hours (7pm–11pm), disrupting critical operations.

CityFibre's business-only network eliminates contention. Your service performs identically during peak and off-peak hours—guaranteed by written SLA with automatic credits for breaches.

Problem 3: Missed Digital Transformation

Slow networks prevent cloud migrations, block security upgrades, and delay modernisation.

CityFibre's reliable, scalable infrastructure enables:

Frequently Asked Questions

Is CityFibre available at my business location?

CityFibre covers over 285 UK towns and cities. Use our CityFibre/FTTP availability checker to confirm service at your postcode. If not yet available, ask about planned rollout dates.

How much does CityFibre cost compared to my current broadband?

Typical CityFibre FTTP packages range £120–£300/month for gigabit-capable speeds. Standard FTTC costs £50–£80/month. Over 3 years, the premium (£20–£50/month) pays for itself through eliminated downtime, improved cloud performance, and elimination of workarounds.

Can I scale CityFibre as my business grows?

Yes. Software-defined scaling means you upgrade speed instantly without physical infrastructure changes. From 100Mbps to 1Gbps takes minutes—no engineer visit, no disruption.

What's included in CityFibre's business SLA?

Typically: 99.9% uptime guarantee, sub-2-hour engineer response, mean time to repair (MTTR) under 4 hours, automatic credit (5–25% of monthly rental) for any breach. Confirm specifics with your provider before signing.

Should I pair CityFibre with cybersecurity upgrades?

Absolutely. As voice and data converge on IP networks, fibre's reliability is only valuable if protected by enterprise cybersecurity services. Real-time threat monitoring over full fibre is far more effective than over slow, unreliable copper.

The Path Forward: Full Fibre is Non-Negotiable

CityFibre is transforming UK business broadband. For organisations ready to invest in cloud, VoIP, security, and hybrid work, full fibre is no longer optional—it's essential infrastructure.

Ask yourself: Is our current network ready for today's cloud and security requirements?

If the answer is "no," the upgrade cost is modest compared to the boost in performance, resilience, and security. Organisations relying on outdated copper face:

  • £500–£1,000+ annually in downtime costs
  • Delayed security incident response
  • Poor employee experience (slow cloud apps, dropped VoIP calls)
  • Competitive disadvantage (faster competitors using modern infrastructure)
