Structured cabling is one of those costs that's genuinely hard to estimate from the outside — it depends heavily on building layout, cable type, and how much of the work can happen before finishes go in. This guide breaks down what actually drives the price, so you can budget accurately for a new office fit-out.
What's Actually Included in a Cabling Quote
A proper structured cabling quote should cover: cable and containment (trunking or conduit), data points at each workstation, patch panels, a network cabinet or rack, termination and testing, and certification documentation. If a quote is missing testing and certification, that's worth asking about directly — untested cabling can look fine on day one and cause intermittent problems months later that are far more expensive to diagnose than to have avoided.
The Main Cost Drivers
Cable Category
Cat5e is the cheapest option and fine for basic needs, Cat6 is the sensible default for most modern offices, and Cat6a costs more but supports 10-gigabit speeds — worth it for server rooms and backbone runs, less necessary for individual desk connections in a typical office.
Number of Data Points
This is usually the single biggest driver of total cost. A good rule of thumb is 2 data points per desk (one for a computer, one spare for a phone, printer, or future need) rather than exactly one per person, since retrofitting a single missed point later costs far more than including it upfront.
Building Layout and Construction Stage
New construction, cabled before walls close up, is significantly cheaper per point than a renovation where cables must be routed around existing finishes, sometimes requiring more visible surface trunking instead of fully concealed routes.
Distance and Backbone Requirements
Multi-floor offices need a backbone connection between floors, usually fibre for anything beyond a short run, which adds cost but is essential for reliable inter-floor performance.
Typical Pricing for a Sri Lankan Office
For a typical 20-person office in the Kandy area, professional structured cabling costs between LKR 150,000 to LKR 300,000 depending on cable type and layout complexity. This includes data points at each workstation, patch panels, a network cabinet, and testing certification. Larger commercial and industrial projects scale up accordingly — a 200-employee factory installation, for example, can involve 150+ cabling points, industrial-grade containment, and a dedicated server room build, moving well beyond typical office-scale pricing.
Where Businesses Overspend — and Underspend
- Overspending on Cat6a everywhere when Cat6 to individual desks and Cat6a only on the backbone would perform just as well for most offices at a lower cost.
- Underspending on data points to save money upfront, then paying significantly more later to add points after finishes are complete and furniture is in place.
- Skipping testing and certification to save a small amount, then facing much larger diagnostic costs when an unverified connection causes intermittent problems that are hard to trace without documentation.
- Choosing a cabling contractor purely on price without checking whether termination, testing, and labelling standards are actually being followed — the visible cost difference between good and poor cabling work is small, but the operational cost difference over several years is not.
New Build vs Renovation: Budget Differently
If you're working with a contractor on a new office build, get your cabling provider involved at the same stage as your electrician — this is the cheapest possible point to install data points, since walls are still open and routing is flexible. For a renovation of an existing space, budget slightly more per point and expect some visible trunking in areas where concealed routing isn't practical without significant additional construction work.
A Real Project for Reference
For a two-floor IT office in Kandy, we installed 80 Cat6 data points and a fibre backbone between floors, including server rack installation and full testing and certification — a project scoped and priced within the typical range above for a similarly sized office, and one that's held up well enough that another local IT company now subcontracts their own cabling work to us.
Getting an Accurate Quote
Phasing the Cost Across a Larger Project
For larger fit-outs, cabling doesn't have to be an all-or-nothing line item. It's reasonable to cable the full building for future capacity while only terminating and activating the data points you need immediately, deferring the smaller cost of activating additional points until a department actually grows into that space. This avoids the more expensive alternative of retrofitting cable runs into a fully finished, occupied building later.
The only way to get a genuinely accurate cabling quote is a site visit — floor plans alone rarely capture every routing challenge a building presents. Our structured cabling service provides free site surveys and detailed quotations for offices, clinics, schools, and industrial premises across Kandy and our wider service areas, so you know the real cost before committing to a fit-out timeline.
