When UK businesses look at upgrading their connectivity, the two options that come up most are a 100Mb leased line and FTTP (Fibre to the Premises). Both promise faster speeds than standard broadband, but the way they’re delivered — and the reliability you can expect — are very different. Here’s how to decide which is right for you.
What Is FTTP?
FTTP is fibre broadband delivered directly to your premises. Unlike older copper-based broadband, FTTP gives you faster speeds (often 300Mb–900Mb download) and can be very cost-effective. But it’s still a shared service. At peak times, you may notice slowdowns because multiple businesses and homes are using the same network capacity. Upload speeds are usually far lower than downloads, which is a challenge if your team relies on cloud apps, VoIP or video meetings.
What Is a 100Mb Leased Line?
A 100Mb leased line is a dedicated, private fibre connection used only by your business. You get symmetrical speeds (100Mb upload and download), uncontended bandwidth (no slowdowns), and a guaranteed 99.999% uptime SLA with rapid fault fix times. While costs are higher than FTTP, leased lines are designed for companies where downtime or congestion simply isn’t an option.
Key Differences: FTTP vs 100Mb Leased Line
| Feature | 100Mb Leased Line | FTTP (Business Fibre) |
|---|---|---|
| Bandwidth | Dedicated & uncontended | Shared with others |
| Speeds | 100Mb symmetrical (up & down) | 300–900Mb down, much lower up |
| Reliability | 99.999% SLA | No strict SLA |
| Support | 24/7 proactive monitoring | Best-effort fixes |
| Price | From ~£180/month | From ~£40–£70/month |
Which Should You Choose?
If budget is the top priority, FTTP is a strong step up from copper broadband and ideal for smaller teams with lighter usage. But if your business depends on cloud systems, VoIP, file transfers or customer-facing services, the guarantees of a 100Mb leased line are worth every penny. It’s the difference between “best effort” and business-grade certainty.
