Fibre leased lines, explained
What is a fibre leased line?
Dedicated capacity.
In both directions.
A fibre leased line provides dedicated, uncontended access bandwidth for your organisation. Symmetrical capacity means the contracted upload and download rates match, which can be useful for busy offices and substantial two-way traffic.
Radian helps you compare bandwidth, service levels, addressing and equipment as a complete service. We also review installation requirements and whether your site needs another route if the primary circuit is interrupted.
See the bigger picture →Built around the work you do
Capacity is the start.
The complete service matters.
Choose the circuit, equipment and support around the applications your site relies on.
Dedicated bandwidth
Contracted access capacity for your circuit provides a different service model from ordinary shared broadband.
Written service levels
Understand the applicable availability measures, reporting process, response arrangements and remedies before ordering.
Fixed addressing
Include public IP requirements for VPNs, remote access and hosted systems in the design. Confirm allocations in the proposal.
Coordinated installation
Plan survey, building access, router configuration and handover with the relevant delivery specialists.
Resilience options
Review diverse fibre, broadband or mobile backup around the impact of a fault and the work that needs to continue.
Explore resilience optionsService availability, equipment, features, licences and support scope are confirmed in your proposal. Optional services are priced and agreed separately.
The picture, made clearer
Think beyond
a single circuit.
A primary circuit and an optional alternative route can form part of a resilience plan. Independent routes, equipment and power need checking.

PRIMARY ROUTE
Fibre leased lineDedicated symmetrical capacity
OPTIONAL ALTERNATIVE ROUTE
Diverse fibre, broadband or mobileChosen around continuity requirements
Internet & cloud servicesReach the applications you need
The backup path is an option to scope, not a standard inclusion. A second circuit does not by itself guarantee route diversity or uninterrupted sessions.
Illustrative design. Actual routing, supported equipment and features depend on the selected service and agreed configuration.
Make an informed choice
Make the specification work for you.
Bandwidth & handover
Agree the contracted rate, physical interface and any future capacity options. Router and firewall throughput must match the intended use.
Service commitments
Read availability, response and restoration definitions separately. The agreement explains scope, exclusions and remedies.
Provisioning & site work
Survey, access permissions and construction can influence delivery. Expected dates and any additional works are confirmed during provisioning.
Continuity, considered
A second route.
A considered fallback.
A leased line is still a physical connection. Cable damage, equipment faults and power loss need a wider continuity design.
Plan your setup ↗Diverse fibre / RO2
Explore physical route diversity and separate network dependencies where available. Confirm what is genuinely independent.
Broadband or mobile backup
A secondary link may support essential work at reduced capacity. Check addressing, signal and application compatibility.
Equipment and power
Review router, firewall and power dependencies alongside the circuits, then test the intended failover behaviour.

A little more clarity
Fibre leased lines,
answered.
Have a question about your site?
Start with the address and what you need.
How fast can our leased line be?
Available bandwidth and bearer options depend on your location, delivery network and chosen service. We confirm the offered specification and any upgrade options in your proposal.
Do we need a leased line or broadband?
Consider upload demand, simultaneous use, the impact of disruption and the service agreement you need. A smaller site can still have demanding requirements; headcount alone is not the deciding factor.
Does dedicated mean we can never go offline?
No. It refers to bandwidth allocation. Faults remain possible, so service levels and a suitable resilience design matter.
How long does installation take?
It depends on existing infrastructure, site access, survey results and any construction. We coordinate the known stages and confirm expected timescales through provisioning.
Is a backup circuit included?
Only where specified in the agreed service. We can compare an additional fibre circuit, broadband or mobile backup and explain the limitations of each.
Will our applications all be faster?
Performance also depends on remote services, routing, devices and the local network. Dedicated capacity helps address access demand; testing confirms how important applications behave.
UK-wide service enquiries
Fibre leased lines across the UK.
Leased-line pricing and delivery depend on the premises and required capacity. Send the full UK installation addresses, target dates and resilience requirements so access options, survey dependencies and service terms can be compared.
Based in Charlwood, we welcome enquiries nationwide, with a particular focus on Horley, Crawley, Gatwick, Surrey, Sussex and London. Delivery, availability and any site attendance are confirmed for your chosen service.
