Uncontended 1:1
The bandwidth is dedicated to your business and not shared with anyone else on the network.
Internet Access
Dedicated Lease Line
When the connection stops, the business stops with it: no card payments, no cloud systems, no one able to work. A lease line is for businesses where that is not an option, with uncontended bandwidth, symmetrical speeds and a service level that carries real weight.

What this protects
Guaranteed bandwidth for a business that cannot stop
A best-effort line shares your bandwidth with the street and slows at the worst moment. A lease line is the capacity you bought, dedicated to you, with a penalty if the carrier misses it.
The bandwidth you actually bought
Uncontended 1:1 capacity, so a quiet Sunday speed test and a Monday morning rush deliver the same result.
Symmetrical, so uploads keep up
The same speed up as down, keeping video calls steady and cloud backups from running all night.
A service level with teeth
Defined response and repair times, with automatic credits if the carrier misses them, so reliability is contractual rather than hoped for.
Contended broadband versus a dedicated line
A standard broadband or superfast line is contended, which means the bandwidth is shared between your premises and others on the same exchange equipment. That is why a speed test on a quiet Sunday looks brilliant and the same line crawls on a Monday morning.
A dedicated lease line is uncontended and 1:1, meaning the full capacity is yours and yours alone. It is also symmetrical, so upload matches download, which matters more than people expect. Asymmetric broadband can wreck a video call and take all night to push a backup to the cloud.
You also get a service level agreement with defined response and fix times, a router with a real public IP range rather than a single dynamic address, and Openreach building dedicated fibre into your premises specifically for you. Where the carrier misses the SLA, the contract usually provides credits.
What you get with a lease line
Symmetrical speeds
As much upload as download, which keeps video calls clear and cloud backups quick.
Service level
Defined response and repair times, with credits applied automatically if the carrier misses them.
Static IP addresses
A proper public IP range for hosting, VPNs, port forwarding and remote access.
Managed end to end
We order it, chase the Openreach build, configure the router and monitor it after handover.
Scalable
Bandwidth can be increased as the business grows, often without a new physical install.
You probably need a lease line if
- The business stops when the internet stops, and downtime has a real cost
- Your team uploads or downloads large files as part of the day job
- You run video calls, VoIP or cloud apps that suffer when bandwidth is shared
- You host services on site or need static IP addresses for reliable remote access
- You want a guaranteed speed and a service level rather than a best-effort connection
Questions we get asked about Dedicated Lease Line
It depends on the bandwidth and how much construction Openreach needs to reach you. A building already fibred is far cheaper than one needing a new dig. We quote against your address and tell you the build cost up front.
Typically six to twelve weeks from order, because a new circuit usually needs a survey and construction. Fibre already at the building can be considerably faster.
Contended means the bandwidth is shared with other premises, so you rarely get the full figure at busy times. 1:1 uncontended means the capacity is dedicated to you and does not drop when the neighbours get busy.
For most businesses, yes. A lease line is highly reliable, but a second path over 4G or 5G keeps you running during the rare fault or local building works. We can design that as part of the setup.
Usually yes. Many lease lines can be increased in place without a new install, though it depends on the carrier and the circuit. We will confirm the position when we quote.
