The cost of shared bandwidth
A contended connection is a risk you're taking without knowing it
Most businesses only find out their connection was never really theirs when it matters most.
- A shared FTTC line slows down when your neighbours get busy, and you have no way of knowing it's happening until it already has.
- Card payments, video calls and cloud backups all fighting for the same bandwidth usually lose exactly when it matters most.
- Most standard broadband SLAs promise a callback, not a fix time. A leased line without one leaves your business waiting.
- Growing teams outgrow shared connections quietly, until the day everything slows down at once.
You're in safe hands
A connection sized to your business, with a service level in writing
A leased line is a bigger decision than broadband, and we treat it that way. We size it to what's actually running on your network, back it with a service level you can hold us to, and stay on hand once it's live.
A business leased line is a fibre connection that only your business uses. Broadband capacity is shared with other users nearby, which is why speeds can drop at busy times. If you're comparing a leased line vs broadband, the difference is the guarantee: symmetrical speeds and a 99.9% uptime SLA in writing.
When you compare leased line providers, ask for the fix time and service credits in writing. Ours are a 4-hour target fix, with credits if we miss it.

Getting connected
How we get your leased line live
Leased lines take longer to install than broadband. We manage that process so you don't have to think about it.
We design around your traffic
We look at what's actually running on your network, voice, video, backups, before sizing the line.
We manage the build
Leased line installs involve wayleaves and groundwork. We coordinate it so you don't have to chase anyone.
We back it with a real SLA
If something goes wrong, you get a fix time in writing, not a queue.
In their own words
“We stopped worrying about our internet the day this went in. It's just there, every time.”
