Choosing between business broadband and a leased line is one of the most important connectivity decisions for companies across the UK and Ireland today. As digital transformation accelerates and remote working becomes standard, the reliability and performance of your internet connection can make or break your business.

In this guide, we’ll compare broadband vs leased line connectivity, helping you understand the differences, costs, and business benefits, so you can make the right choice for your organisation.

Broadband Vs Lease Lines

What’s the Difference Between Business Broadband and Leased Line?

Business Broadband

Business broadband provides internet access via shared infrastructure, typically using FTTC, FTTP, SoGEA, or ADSL. Multiple users share capacity, making it cost-effective but potentially variable during peak times.

Leased Line

A leased line delivers a dedicated, uncontended connection from your premises to your provider’s core network — giving you guaranteed speeds, symmetrical performance, and higher reliability.

Think of it as having your own private motorway instead of sharing public roads.

Speed and Performance

Broadband

  • Download speeds: typically 30–1000 Mbps
  • Upload speeds: often slower than download
  • Performance varies with local network congestion
  • Advertised “up to” speeds not always guaranteed

Leased Line

  • Symmetrical speeds (equal download and upload)
  • Guaranteed bandwidth via SLA
  • Consistent performance — unaffected by peak usage
  • Highly scalable: 10 Mbps to 10 Gbps

Real Business Example:
A Belfast video production agency cut file upload times from 4 hours to 45 minutes after upgrading from 80 Mbps broadband to a 100 Mbps leased line – thanks to symmetrical speeds and guaranteed performance.

Cost Comparison: Broadband vs Leased Line

Business Broadband

  • From £30–£150/month
  • Installation in 2–4 weeks
  • Low upfront costs
  • Flexible contract terms

Leased Line

  • From £300–£2000+/month
  • Installation takes 8–16 weeks
  • Higher setup costs
  • Typically 3–5 year contracts

Total Cost of Ownership:
While broadband is cheaper upfront, consider productivity losses, downtime risks, and future scalability needs when evaluating long-term value.


Reliability and Uptime Guarantees

Business Broadband

  • Uptime: 99.5–99.7%
  • Best-effort fault resolution
  • Shared infrastructure = higher risk of outages

Leased Line

  • Uptime: 99.9–99.99%
  • Priority fault resolution (4–6 hours)
  • Dedicated connection minimises failure points

Example:
A Newry accounting firm reported 99.95% uptime with its leased line, compared to 98.2% on its previous broadband – eliminating critical outages during month-end processing.

When to Choose Business Broadband

Business broadband is ideal for:

  • Professional services (5–25 staff) using cloud apps and email
  • Small retail outlets with EPOS systems and guest WiFi
  • Charities with budget constraints needing cost-effective solutions
  • Education settings where FTTP can support blended learning

  • Mission-critical operations: financial services, call centres, ecommerce
  • Multi-site organisations requiring seamless WAN connectivity
  • Large user environments: schools, hotels, coworking spaces
