If you've started thinking seriously about connectivity in your commercial building, you've probably encountered a confusing range of options, providers, and approaches. Some look similar. Some promise the same outcomes. And the terminology - leased lines, broadband, FTTP, FTTB, managed networks, point-to-point - isn't always explained in plain English.
This post is a straightforward guide to the main connectivity approaches available to commercial landlords in 2026, with honest assessments of what each one delivers, what it costs, and which buildings it suits best.
One note upfront: Fibre Force is one of the providers discussed below. We've tried to be as objective as possible about where we're the right fit and where another approach might suit better. That's what we'd tell you in a conversation, and it's what we'll tell you here.
What it is: The landlord provides no connectivity infrastructure. Each tenant arranges their own internet connection on arrival.
What it costs: Nothing upfront. But there are real costs embedded in the approach: ISP lead times of 12–24 weeks that delay operational readiness, lost deals from tenants who can't wait, and reduced competitiveness against buildings that have addressed connectivity.
Best for: Buildings with long-term single tenants who handle their own infrastructure requirements and don't need to be operational on day one.
Not suitable for: Multi-let office buildings where vacancy is a concern, where tenants turn over regularly, or where the landlord wants to attract modern businesses that expect connectivity to be a building feature.
What it is: A dedicated, symmetric internet connection into the building, typically a fixed bandwidth (e.g. 1Gbps) provided by a single ISP. The landlord or managing agent contracts and pays for the line, and often resells bandwidth to tenants.
What it costs: Typically £300–£1,000+ per month depending on speed and provider, plus installation costs. The landlord manages the contract and is responsible for uptime.
Best for: Buildings with a small number of tenants who want a shared, managed connection and where the landlord is comfortable managing ISP relationships.
Not suitable for: Large multi-let buildings where individual tenants want their own dedicated connectivity, different speed tiers, and direct ISP relationships. Also involves the landlord in ongoing IT management, which most don't want.
What it is: Each tenant gets their own individual fibre or broadband connection, arranged separately with the ISP of their choice.
What it costs: The costs are variable. Each tenant pays their own ISP. But the building-level coordination overhead is significant: multiple wayleave agreements, multiple ISP engineers, multiple installation timelines, congested risers.
Best for: Buildings where tenants have very different connectivity requirements and strong ISP preferences.
Not suitable for: Buildings where the landlord wants a clean, consistent connectivity story to tell prospective tenants, or where the coordination of multiple individual installs creates complexity.
What it is: Building-grade gigabit fibre infrastructure installed across every floor and every unit, with connectivity available to tenants from day one. Tenants choose their speed tier and minimal initial term; the network management is handled by Fibre Force.
What it costs: Nothing to the landlord. Fibre Force funds the installation and recoups the cost through tenant service agreements.
What it delivers: Every tenant is operational from day one. No ISP lead time. No coordination overhead for the landlord. A building-wide 99.95% uptime SLA. And a compelling feature for leasing agents to lead with.
Best for: Multi-let commercial office buildings where vacancy is a concern, where tenants turn over, and where the landlord wants connectivity to be a feature of the building, not a problem that each tenant should have to solve.
Not suitable for: Single-tenant buildings, owner-occupied properties, or very small buildings where the tenant base doesn't support the Fibre Force commercial model.
For most multi-let commercial office landlords dealing with vacancy or wanting to improve lettability, the right answer is Option 4. The zero-cost model removes the financial objection. The zero-coordination model removes the operational objection. And the outcome (a building where every tenant is connected from day one) is what the modern occupier market increasingly expects.
If you're not sure whether the Fibre Force model is right for your specific building, the most useful next step is to request a free survey. We'll assess the building, explain exactly what the installation would involve, and tell you honestly whether this is a good fit.
The best connectivity solution for a commercial office building is the one that removes the connectivity question from the leasing conversation entirely. For most multi-let buildings, that means pre-installed in-building fibre.
