Are Leased Lines Worth the Higher Price Tag? A Cost–Benefit Analysis

If It Costs More, It Needs to Deliver More

For many businesses, switching from broadband to a leased line feels like a big leap, especially when the price tag is two or three times higher. But that number alone doesn’t tell the full story.

The question isn’t just what does it cost? It’s what do you get – and what do you avoid – by making the switch?

Let’s break it down.

What You’re Really Paying For

A leased line isn’t just “faster internet.” It’s a fundamentally different service. Here’s what that higher monthly fee buys you:

  • Dedicated bandwidth – no contention, no peak-hour slowdowns
  • Symmetrical speeds – fast uploads and downloads, 24/7
  • Guaranteed uptime – typically 99.9% or better
  • SLAs with fix times – many offer 4-hour resolution guarantees
  • Custom configuration – tailored to your needs, with flexible scaling
  • Priority support – business-grade response from real engineers

In contrast, standard or ‘normal’ business broadband gives you:

  • Shared bandwidth (with unpredictable speed drops)
  • Asymmetrical performance (slow uploads)
  • Best-effort service with long fix windows
  • Variable performance based on local demand

 

How Much More Does It Cost?

A typical leased line might cost:

  • £200–£350/month for 100Mbps
  • £300–£600/month for 1Gbps
  • Higher tiers vary based on location and precise infrastructure

By comparison, business broadband might range from £30 to £80/month. But you’re not comparing like for like, you’re comparing:

Shared access with no guarantees vs A private, SLA-backed service that keeps your business online

Where the Value Really Shows Up

Value AreaLeased Line Advantage
ProductivityLess waiting, fewer issues, more Uptime
ReliabilityProtected against peak-time congestion
SupportRapid SLAs, proactive monitoring
Customer ExperienceNo glitchy calls or slow portals
ScalabilityEasily increase speed as you grow
Risk ReductionAvoid outages that cost time and money

In short – leased lines help businesses operate better, serve customers faster, and grow without the bottlenecks.

When Is It Worth It?

Leased lines make the most sense when:

  • You rely heavily on cloud apps, VoIP, or remote work
  • Downtime causes real disruption (or reputational damage)
  • Your team size, data use, or complexity is growing
  • You’ve outgrown “just good enough” connectivity

Think of it like office space – you could cram 20 people into a small room with no windows, but would it support productivity, morale, or business growth? Probably not.

What If You’re Not Ready Yet?

Some smaller business owners may not feel like they need a leased line right now. But planning ahead can still help. Look for:

  • Providers who offer upgrade paths from broadband to leased
  • Contracts with flexible terms, not auto-renewal traps
  • An ROI model so you know when leased lines start to pay off

Even a short-term investment in better connectivity can unlock:

  • Smoother launches
  • Better platform performance
  • Confidence in future hiring or hybrid work plans

Final Word

Leased lines cost more than business broadband, but they offer uncontended speeds, symmetrical bandwidth, guaranteed uptime, and strong SLAs. For businesses that rely on cloud services, remote teams, or customer-facing platforms, the productivity and performance benefits quickly justify the higher monthly cost.
