When your organisation relies on cloud systems, customer calls and large uploads, the quality of its internet connection affects everyday work. Stratiis helps businesses across Scotland choose, install and manage leased lines that fit their actual demand.
What is a business leased line?
A leased line is a dedicated data connection for your organisation. It usually provides committed bandwidth, symmetrical upload and download speeds, and business-grade service commitments. It can deliver internet access or a private connection between sites, depending on the product ordered. The right choice depends on your usage, location, contract terms and the business cost of disruption.
When it makes sense
Is your current broadband creating a business risk?
Consider a leased line when busy-hour performance changes, upload capacity restricts video or file transfers, customer calls depend on stable connectivity, or a lengthy outage would stop a large part of the organisation. Contact centres, shared service hubs and multi-site networks may have particular needs.
A slow cloud application does not automatically mean the internet circuit is the cause. Firewalls, switches, Wi-Fi, devices or the application itself may be the bottleneck. We review the full path before recommending a more expensive connection.
Committed capacity
Agree the bandwidth your service receives rather than relying only on an “up to” download figure.
Equal upload and download
Symmetrical speeds help where teams send files, use video and back up to the cloud.
Service commitments
Review support, fault response, target repair and the exclusions in the actual SLA.
Growth options
A suitable bearer may allow later speed upgrades within its installed capacity.
Compare your options
Leased line or business broadband?
Both connect your business to online services. Full Fibre business broadband can be excellent value for many organisations. A leased line is more likely to be justified when predictable upload capacity and the service commitment are worth its higher cost and longer delivery.
| Decision point | Business broadband | Leased line |
|---|---|---|
| Capacity | Usually sold with an “up to” access speed; network capacity may be shared. | Contracted bandwidth is committed to your service. Confirm the CIR in the proposal. |
| Upload | Can be lower than download, depending on the product. | Typically symmetrical, with matched upload and download rates. |
| Service terms | Business support and repair options vary by product. | Usually includes stronger service commitments; read targets and exclusions carefully. |
| Delivery and cost | Often quicker to provide and lower in monthly cost. | Often higher cost and a dedicated installation that can need surveys or construction. |
| Best fit | Many offices, branches and organisations whose risk and usage fit the service. | Critical locations, heavier uploads, large concurrent demand or tighter continuity needs. |
Explore Business Broadband for the alternative. A strong broadband connection with suitable backup may be the better overall design for some sites.
Understand the quote
Committed speed, bearer and CIR: what are you buying?
Active bandwidth is the speed you purchase now. The bearer is the maximum capacity of the installed connection. A business might buy 200 Mbps on a 1 Gbps bearer and upgrade later if the provider’s terms allow. Committed Information Rate (CIR) describes the bandwidth the provider commits to making available; it should be explicit in the quote.
Ask whether the speed is symmetrical, whether the full bearer is active, and what an upgrade would cost or require. A large bearer can make sense for growth, but paying for unused active capacity does not help the business.
Is 100 Mbps enough?
It may be for a smaller organisation with managed traffic. Check busy-hour use, simultaneous Teams meetings, Hosted Voice, large uploads, cloud backup, CCTV and growth. A committed 100 Mbps service can be more consistent than a higher headline broadband speed.
Do you need 1 Gbps?
It may suit larger teams, contact centres, multi-site traffic or data-heavy work. First confirm that the firewall, switches and cabling can pass the traffic with security features enabled. Otherwise the local network may cap the benefit.
Delivery planning
What happens during leased-line installation?
A provider checks availability, surveys the site and plans a route into the building. Delivery can involve fibre work, internal cabling, landlord permissions, a wayleave, router installation and testing. Some orders are straightforward; blocked ducts, roadworks or construction can extend the timetable.
A wayleave gives the provider permission to install or maintain equipment on property it does not own. Excess construction charges can arise when additional ducts, crossings or building entry work are needed. Ask for the survey outcome and any charges before committing to a final plan.
Order early
Installation can take weeks or months depending on site conditions. Begin availability checks early in an office move or major project, and treat dates before survey as indicative.
Plan temporary access
If the new line will not be ready for opening day, assess business broadband, 4G/5G or another interim service against users, calls, security and the likely duration.
Migrate carefully
Check static IPs, DNS, VPNs, firewall rules and cloud allow lists. Keep the existing connection active until the new line and critical applications have been tested.
The full network
A dedicated circuit is only one part of performance
The router, firewall, switches, cabling, Wi-Fi and user devices must support the contracted speed. Firewall throughput with inspection and VPN features enabled can be much lower than a headline hardware rating. Define who owns each part of the service so faults do not bounce between providers.
Voice and collaboration
Stable bandwidth helps Teams, video and Hosted Voice, but call quality also depends on delay, packet loss, local Wi-Fi and the cloud platform. Prioritise voice and test real calls.
Customer contact
Calls, CRM, recording and agent tools can fail together if a contact centre loses internet access. Size both primary and backup capacity for concurrent agents.
Cloud and multi-site work
Uploads, backups and shared applications may benefit from symmetrical capacity. Design VPN, SD-WAN or private links around where systems and users actually sit.
Product choice
Internet leased line or private circuit?
An internet leased line gives dedicated access to the public internet for cloud services, browsing, voice and video. A private leased line or point-to-point Ethernet service connects defined locations, such as an office and data centre, and may not include general internet access. Some organisations use both.
Ethernet product names differ between carriers. Read the specification for what the circuit connects, whether internet access is included, committed speed, bearer, service level and resilience. The label alone does not tell you what is delivered.
Continuity
A leased line still needs a backup plan
Fibre damage, provider faults, local power loss or a failed router can interrupt a dedicated line. A business-critical site may use a second broadband connection, mobile service, fixed wireless or another leased line. The backup should carry the applications that must continue, even if it has less capacity than the primary.
Two leased lines do not automatically mean diverse routes. They may share a duct, exchange, building entry, router or power. Confirm the actual separation and test automatic failover, voice, VPNs, static-IP dependencies and return to normal service.
Explore Internet Failover for backup design and testing.
Service ownership
Read the SLA, monitoring and security terms
A Service Level Agreement may define availability, fault response, target repair, performance and credits. A target repair time is not always a guaranteed restoration time, and credits may be small compared with the operational cost of an outage. Check how downtime is measured, exclusions, hours of support and escalation.
Monitoring and fault response
Useful monitoring covers availability, bandwidth, packet loss, delay, router status and failover. During a fault, the support team should distinguish a carrier issue from local power, router, firewall or Wi-Fi trouble, then coordinate escalation and updates.
Static IPs and security
Static public IPs can support VPNs and allow lists, but are not a security control by themselves. Size and configure firewalls, access controls, encryption and monitoring for the exposed services. Consider DDoS protection where the risk warrants it.
Site priorities
Where can dedicated connectivity add value?
A housing association head office, contact centre or shared-service hub may need committed capacity for tenant contact, repairs systems and many users. Accountancy and professional-services firms may value predictable uploads, client portals, cloud applications and video at busy deadlines. A charity may justify a leased line for an essential service, while other offices use Full Fibre broadband.
Multi-site organisations can mix technologies: dedicated access at a central location and business broadband at smaller branches, with appropriate backup at each. The choice follows the importance of the location and the applications it carries, not a uniform speed target.
Costs and trade-offs
What should a leased-line decision include?
Compare monthly rental, installation, excess construction, router, firewall, support, backup and contract term. A leased line can take longer to install and may be tied to the premises for a longer commitment. A move can require a new order while the old service remains in contract.
Ask for active bandwidth and bearer, upgrade terms, static IP allocation, repair target, support hours, carrier, route information and the cost of early termination. Check both under-sizing and over-sizing against real busy-hour demand and growth.

Direct answers
Leased line FAQs
Answers to common questions about dedicated business connectivity.
What is a business leased line?
It is a dedicated data connection for one organisation, usually providing committed bandwidth, symmetrical upload and download speeds and business service commitments. The exact product and SLA should be checked in the proposal.
Is a leased line the same as fibre broadband?
No. Both can use fibre, but a leased line typically commits dedicated capacity to your service. Full Fibre broadband may offer excellent speeds at lower cost while using shared network capacity and different service terms.
What does symmetrical speed mean?
The contracted upload and download speeds are the same, such as 100 Mbps in each direction. This can help with video, voice, file transfers and cloud backup.
What is dedicated bandwidth?
The agreed service capacity is committed to your connection rather than sold as an “up to” access speed. Application performance still depends on the local network, destination and equipment.
What is a leased-line bearer?
The bearer is the installed connection’s maximum capacity. You might buy 200 Mbps active bandwidth on a 1 Gbps bearer, leaving scope for an upgrade subject to provider terms.
What is CIR?
Committed Information Rate is the bandwidth the provider commits to making available. Check the CIR separately from the bearer’s maximum capacity and any headline marketing speed.
Is a leased line faster than broadband?
Not necessarily in headline download speed. Its value often lies in committed, symmetrical and more consistent capacity plus the support terms. Compare measured needs and total service terms.
Is a 100 Mbps leased line enough?
It can be for some small or medium organisations, but the answer depends on concurrent users, uploads, meetings, voice, backups and future growth. Review busy-hour usage before choosing.
Do we need a 1 Gbps leased line?
Only if current or expected workloads justify it. Check whether the firewall, switches and cabling can handle the speed, and whether a lower active rate on a larger bearer is more sensible.
How long does a leased line take to install?
Times vary by site. A straightforward installation may take weeks; surveys, construction, blocked ducts, wayleaves or road access can extend it to months. Do not treat an indicative date as guaranteed.
What is a wayleave?
A wayleave is permission for a provider to install or maintain communications equipment and cabling on property it does not own. Landlord or managing-agent involvement can affect the delivery date.
What are excess construction charges?
They are additional costs for work beyond a standard installation, such as new ducts, crossings or building entry. Review the survey result and approve any charge only after comparing alternatives.
Does a leased line come with a router?
That depends on the offer. Check whether a router is included, who manages it, what support applies and how it connects to your firewall and backup service.
Does a leased line need a firewall?
A business internet connection should be protected as part of the wider security design. Size the firewall for the contracted speed with the security features and VPNs you intend to use.
Can a leased line support Microsoft Teams and Hosted Voice?
Yes, its stable capacity can be a good foundation. Call and meeting quality also depends on Wi-Fi, switches, devices, firewall configuration and the service at the other end.
Can a leased line fail?
Yes. Fibre damage, power, router, provider or internal network faults can interrupt service. A critical site should have tested backup connectivity and a clear incident plan.
What is the best backup for a leased line?
It depends on required capacity, outage impact and route diversity. Options include business broadband, 4G/5G, fixed wireless or a second leased line. Test critical applications on the backup.
Do two leased lines provide full resilience?
Only if shared failure points have been addressed. Two circuits may use the same duct, exchange, building entry, router or power source. Ask for evidence of the diversity delivered.
Can failover happen automatically?
Yes. A suitable router, firewall or SD-WAN design can move traffic to the backup. Test detection, application behaviour and return to the primary connection.
Can we upgrade the speed later?
Often, when the installed bearer has spare capacity, but the process, charges, contract terms and timing vary. Confirm these in the quotation.
Can we move a leased line to a new office?
A move usually requires a new service order at the new address. The current circuit may remain under contract, so check overlap, cancellation terms and temporary connectivity early.
How much does a leased line cost?
Pricing depends on location, carrier, speed, bearer, contract term, installation and construction, router, support and backup. Compare the total cost with the effect of slow service or downtime.
Can Stratiis compare carriers and manage the wider network?
Stratiis can assess available carriers and, within the agreed scope, coordinate installation, routers, firewall, Wi-Fi, monitoring and backup so ownership is clear.
