It is the wrong question — and asking it leads to bad decisions, because it assumes there is a winner. There is not. A leased line, bonded SD-WAN, and Integra Bridge are not competing for the same slot. They solve different problems, on different timelines, for different kinds of site. The useful question is not "which is best" — it is "which fits _this_ site, given what it needs and when it needs it." This piece is a framework for answering that. 02 ## The three options **Leased line.** A dedicated fibre circuit — symmetric, uncontended, SLA-backed. The gold standard for a permanent site that cannot afford downtime. Its weaknesses are lead time and, where civils are involved, an excess construction charge that can run into five figures. Its other weakness can be resilience. In the rare case where fibre develops a fault or is cut, it is best to have an alternative backup configured for automatic failover. If that backup is another fibre circuit, customers and partners need to be sure it is not running through the same ducts or sharing single points of failure with the main circuit. Integra Bridge (available everywhere) solves that problem, as do other fixed wireless options which may or may not be available depending on location. **Bonded SD-WAN.** Multiple 4G/5G carriers combined into one resilient connection — load balanced or bonded. Live in around fourteen days, with no Openreach dependency. The right answer where Fibre cannot reach a site, takes too long to install, or costs too much to bring in. **Integra Bridge.** Bonded Starlink and 5G/4G delivered over Layer 2 from our data centre — enterprise-grade connectivity in around ten days, purpose-built for the gap while a permanent circuit is being constructed. When the fibre lands, Integra Bridge does not get removed; it stays on as automatic failover. 03 ## The five decision factors Five questions decide the fit. Run a site through all five and the answer usually resolves itself. **Lead time.** When does the site actually need to be live? If the answer is "before the leased line install date" — and it often is — then the immediate decision is not a leased-line decision at all. It is a bonded SD-WAN or Integra Bridge decision, very possibly running _alongside_ the leased line order rather than instead of it. **Location.** Can fibre reach the site economically? A quote that comes back with a heavy excess construction charge, or stalls on a wayleave, is not a reason to wait — it is a signal that bonded SD-WAN or Integra Bridge has stopped being the compromise and become the better primary. **Workload.** What actually runs on the connection? A site that needs inbound access — VPNs terminating on-site, CCTV, remote support — needs a static IP, which points firmly toward a leased line or a bonded configuration rather than a basic load-balanced setup. **Permanence.** Forever site, or temporary one? A construction site that relocates every six months is never a leased-line decision — the circuit would be obsolete before it paid back. A head office is the opposite. Match the contract length and the technology to the life of the site. **Resilience.** Single circuit, or no single point of failure? This is the factor most often skipped. Any of the three options can serve as a primary; any can serve as a backup. The strongest sites run a primary circuit _and_ an independent wireless connection that fails over automatically — so the question is not only "what is the primary," it is "what is behind it." The useful question is not "which is best." It is "which fits this site, given what it needs and when it needs it." 04 ## The framework Run those factors and most decisions resolve cleanly: - Permanent site, fibre available, timeline works → leased line. - Permanent site, fibre cannot reach or costs too much → bonded SD-WAN or Integra Bridge as the primary. - Permanent site, fibre ordered but months away → Integra Bridge now, leased line later, Integra Bridge stays as failover. - Temporary or moving site → bonded SD-WAN or Integra Bridge, every time. - Any site that genuinely cannot go dark → a primary circuit _plus_ bonded SD-WAN or Integra Bridge, whatever the primary is. 5 factors lead time, location, workload, permanence, resilience — the questions that decide the fit 05 ## Why it is usually a combination Here is the part the "which is best" framing misses entirely: for anything bigger than a single site, the right answer is almost never one product. An estate has a head office that warrants a leased line, regional sites where bonded SD-WAN or Integra Bridge is the sensible primary, a new location where Integra Bridge covers the gap until fibre arrives, and a temporary site that will only ever be wireless. A connectivity _strategy_ is not picking a winner — it is matching each site to what it needs, and layering the right resilience behind each one. The job of the framework is not to crown a product. It is to make every individual decision quick, defensible, and right for that site. Talk to us ## Got a site that fibre can't reach? Getting the awkward sites online is what we do.
