For most businesses, a standard broadband connection — even a good one — is a shared resource. You're using the same infrastructure as other businesses and homes in your area, and when demand is high, performance can suffer. For businesses where internet connectivity is genuinely mission-critical, that shared, best-effort model isn't good enough.
A leased line is different. It's a dedicated connection, installed exclusively for your business, with guaranteed speeds that don't vary based on what anyone else is doing. Upload and download speeds are fully symmetrical, latency is consistently low, and the connection comes with a Service Level Agreement that commits to response and resolution times if something goes wrong. It's the connectivity solution for businesses that cannot afford for their internet to be anything other than excellent.
We Do Your Comms supplies and manages leased lines for businesses that need guaranteed, enterprise-grade connectivity — handling everything from the initial survey and order through to installation, ongoing management, and support. Give us a call on 0117 982 9666 — we're here Monday to Friday, 8:30am to 5:30pm — and we'll discuss whether a leased line is the right solution for your business.
A leased line is a dedicated, private internet connection installed exclusively for your business. Unlike broadband — whether FTTC or FTTP — which is a shared service where bandwidth is distributed across many users on the same infrastructure, a leased line provides a connection that is used solely by your organisation. No sharing, no contention, no performance variation based on what neighbouring businesses or homes are doing.
Leased lines are delivered over fibre optic infrastructure and provide fully symmetrical speeds — meaning upload and download speeds are equal. This is a significant distinction from broadband, which typically provides much lower upload speeds than download speeds. For businesses that need to send as much data as they receive — backing up to the cloud, uploading large files, running hosted servers, or supporting heavy video conferencing usage — symmetrical speeds make a practical and noticeable difference.
Because the connection is dedicated, speeds are guaranteed rather than estimated. A leased line contracted at a particular speed delivers that speed consistently — at peak times, in bad weather, regardless of local demand. This predictability is what underpins the reliability that businesses with the highest connectivity requirements depend on.
Leased lines are also backed by a Service Level Agreement (SLA) that commits the provider to specific response and resolution times in the event of a fault — typically with four-hour or eight-hour fix targets and proactive monitoring that means faults are often identified and progressed before the customer is even aware of them.
Pricing is on application, as leased line costs depend on the speed required, the location of the premises, and the distance from the nearest network infrastructure. We conduct a survey and provide a clear, itemised quote before any commitment is made.
A leased line is not the right solution for every business — it costs more than broadband and for businesses with modest connectivity requirements, FTTP will often be sufficient. But for businesses where the internet connection is a critical operational dependency, the case for a leased line is compelling.
The key question is what the cost of poor connectivity actually is. If slow speeds, latency spikes, or downtime directly affects your ability to serve clients, process transactions, support remote workers, or run your phone system, the commercial cost of inadequate connectivity needs to be weighed against the premium of a leased line. For many businesses in that position, the maths is straightforward.
Leased lines are particularly well suited to businesses with high and consistent bandwidth demands — those running hosted phone systems for large teams, operating cloud-based infrastructure, supporting significant numbers of remote workers over VPN, using real-time data applications, or simply needing the assurance that their connection will never be the variable that lets them down.
They're also the right choice for businesses with formal uptime requirements — whether because of client SLAs, regulatory obligations, or simply because the cost of an extended outage is unacceptable. The SLA that comes with a leased line provides a contractual commitment to fault resolution that standard broadband cannot match.
Dedicated, Uncontended Connection — a fibre optic connection installed exclusively for your business, with no shared infrastructure and no performance variation based on external demand. Your bandwidth is yours, all of the time.
Guaranteed Symmetrical Speeds — upload and download speeds are equal and guaranteed at the contracted rate. A 100Mbps leased line delivers 100Mbps in both directions, consistently, regardless of time of day or network load.
Service Level Agreement (SLA) — a formal SLA committing to specific response and resolution times in the event of a fault, typically including proactive monitoring, rapid engineer dispatch, and defined fix targets.
Proactive Fault Monitoring — the connection is monitored continuously by the network provider. Faults are identified and progressed proactively, often before the customer is aware of a problem.
Static IP Addresses — leased lines include one or more static IP addresses as standard, essential for businesses hosting services, running remote access, or requiring a consistent IP for security or compliance purposes.
Low and Consistent Latency — dedicated fibre infrastructure delivers consistently low latency, which is critical for VoIP, video conferencing, remote desktop, and any real-time application.
Scalable Bandwidth — leased lines are available across a range of speed tiers, from 10Mbps up to 10Gbps and beyond, with the ability to upgrade bandwidth as business requirements grow.
Router and Installation — installation is carried out by a qualified engineer, with a compatible business-grade router supplied and configured as part of the setup.
Ongoing Support — your leased line is managed and supported by our Bristol-based team throughout the contract. Faults and queries are handled by us, with escalation to the network provider managed on your behalf.
Survey and Quotation — before any commitment, we conduct a survey of your premises and provide a clear, itemised quotation covering installation, equipment, and monthly rental costs.
Guaranteed performance — every hour of every day — because the connection is dedicated and uncontended, performance is consistent regardless of time of day, local demand, or network load. The speed you contract for is the speed you get, reliably and without exception.
Symmetrical speeds for data-intensive businesses — equal upload and download speeds make a significant practical difference for businesses that send as much as they receive — cloud backups, large file transfers, video conferencing, VoIP, and hosted server access all benefit directly from high, consistent upload speeds that broadband cannot match.
Low latency for real-time applications — dedicated fibre infrastructure delivers consistently low latency, which is what makes VoIP calls sound clear, video conferences run smoothly, and remote desktop sessions feel responsive. On a shared broadband connection, latency spikes are common under load — on a leased line, they aren't.
An SLA that means something — the Service Level Agreement on a leased line provides a contractual commitment to fault response and resolution. If the connection goes down, there is a defined and enforceable timeline for getting it fixed. This is categorically different from the best-effort approach of standard broadband.
Proactive monitoring — problems caught before they affect you — continuous monitoring of the connection means faults are often identified and progressed before they become noticeable. This proactive approach to fault management is part of what justifies the investment in a leased line for businesses with high availability requirements.
Static IP addresses as standard — leased lines include static IPs as part of the package, which is important for businesses hosting services, running VPNs, or requiring a consistent address for security or compliance purposes. On broadband, static IPs are typically an add-on.
A connection the rest of your infrastructure can depend on — VoIP phone systems, cloud applications, remote workers, and hosted services all perform better and more reliably on a leased line. When connectivity is the foundation everything else sits on, it makes sense to get that foundation right.
Managed and supported locally — your leased line is managed by our Bristol-based team throughout the contract. Fault reporting, escalation, and day-to-day support are all handled by people who know your setup, not a large provider's consumer helpline.

A leased line is a dedicated, private internet connection installed exclusively for your business. Unlike broadband — including FTTP — which is a shared service where infrastructure is used by multiple businesses and homes simultaneously, a leased line is uncontended. Your bandwidth is yours alone, speeds are guaranteed and symmetrical, and the connection comes with a formal SLA committing to fault response and resolution times. Broadband is a best-effort service; a leased line is a guaranteed one.
A leased line is the right choice for businesses where internet connectivity is genuinely mission-critical and the cost of poor performance or downtime is significant. This typically includes businesses running hosted phone systems for large teams, operating cloud-based infrastructure, supporting substantial numbers of remote workers, using real-time data applications, or holding client SLAs that depend on consistent uptime. For businesses with more modest requirements, FTTP broadband is often sufficient and considerably more cost-effective.
Leased line pricing depends on the speed required, the location of the premises, and the distance from the nearest network infrastructure. Because of this variability, pricing is on application — we conduct a survey and provide a clear, itemised quotation covering installation costs, equipment, and monthly rental. Get in touch and we’ll get you a quote.
Leased lines are available across a wide range of speed tiers, typically from 10Mbps up to 10Gbps and beyond, depending on your location and requirements. Unlike broadband, speeds are fully symmetrical — equal upload and download — and guaranteed at the contracted rate. We’ll advise on the appropriate speed for your usage as part of the quotation process.
The SLA typically commits the provider to specific response times from fault notification, defined engineer dispatch timelines, and fix targets — often four or eight hours for a full restoration. The connection is also monitored proactively, meaning faults are often identified and progressed before you’re aware of them. The exact SLA terms depend on the product and provider — we’ll confirm these clearly as part of the quotation.
Leased line installation typically takes longer than broadband, as it involves dedicated infrastructure being installed to your premises. Lead times vary depending on location and the complexity of the installation, but are commonly in the range of 30 to 90 days from order. We’ll confirm the expected timeline at the point of survey and keep you updated throughout the process.
Yes — static IP addresses are included as standard with a leased line. The number of IPs included depends on the specific product and provider. If you have particular IP requirements — for hosting, remote access, or compliance — let us know and we’ll ensure the right provision is included.
Yes — a leased line is an excellent foundation for VoIP. The guaranteed speeds, consistent low latency, and symmetrical bandwidth mean VoIP calls perform reliably with high audio quality, even under heavy concurrent usage. If you’re running a hosted phone system for a large team, a leased line removes the connectivity variable entirely.
Faults are reported to us and we manage the escalation process with the network provider on your behalf. The SLA commits to defined response and fix timelines, and proactive monitoring means faults are often identified before you need to report them. You won’t be navigating a large provider’s consumer support process — our team handles it for you.
