When cabling quotes for the same office differ by 60%, the instinct is to assume someone is overcharging. Usually that is not what happened. Usually the two quotes describe different work, and the per-drop number — the figure everyone compares — hides the difference.
This post explains what actually drives the cost of a drop, where Cat6A and fibre genuinely differ, and how to compare bids so you are comparing the same thing.
The single most important fact about cabling cost
Labour dominates. Across the commercial cabling market, roughly 70–80% of the installed cost of a drop is labour, not materials. The cable itself is a minor line item.
Almost everything else follows from this.
It explains why upgrading the cable category costs less than people expect — you are changing a small fraction of the total. It explains why small jobs cost so much per drop, because mobilisation and minimum-day labour get spread across few drops. It explains why retrofit costs more than new construction, because pulling cable through a finished, occupied space is slow, awkward work.
And it explains the most consequential decision on the whole list: when you cable, not what you cable with.
Timing beats specification
Cabling during the fit-out — while ceilings are open, walls are unclosed and containment is going in anyway — is dramatically cheaper than cabling the same building after handover. The cable is identical. The labour is not remotely comparable.
If you are reading this while your fit-out is still in design, that is the moment where the money is. Every drop you can specify now, before the ceiling closes, costs a fraction of what it will cost as a change order in month eight. This is also why we push clients to over-provision at fit-out stage: an extra drop pulled now is cheap insurance, and an extra drop pulled later is a small project.
What a per-drop quote should include
Two quotes with the same number can cover very different scopes. Before comparing, confirm each of these is in or out:
- Cable, containment and pathway
- Termination at both ends — outlet and patch panel
- Faceplates, patch panels, and the patch leads
- Labelling to a documented convention
- Certification testing (not “we tested it” — certified test results per link)
- As-built documentation and test reports handed over
- Firestopping at any penetration
- Comms room work: rack, cable management, dressing
- Making good — ceiling tiles, trunking, decorative reinstatement
Certification testing and documentation are the two most commonly excluded items, and they are the two you will most regret not having. A test report is what lets a future contractor diagnose a fault in twenty minutes instead of a day. It is also what you need when a manufacturer warranty is claimed.
The cheapest quote in a set is very often the one missing testing, documentation, or comms room scope. It is not cheaper work; it is less work.
Cat6A vs Cat6: the upgrade that is smaller than it looks
Cat6A is now the default for commercial horizontal cabling, and the reasoning is straightforward.
Both Cat6 and Cat6A support 10 Gigabit Ethernet. The difference is distance. Cat6 supports 10Gbps only to about 55 metres; Cat6A supports it to the full 100 metres under ANSI/TIA-568. In an office of any size, runs from the comms room routinely exceed 55 metres, which makes Cat6’s 10G capability theoretical rather than usable.
Cat6A also handles PoE++ heat loads better — which matters more every year, as access points, cameras, access control readers, IP speakers and sensors all draw power over the same cable.
Because labour dominates the total and labour is broadly similar for both, the category upgrade is a modest percentage of project cost. A useful rule: if Cat6A adds 10–15% to the total project, take it. If it adds 40% or more, something else is going on in that quote and you should ask what.
The one real caveat is physical. Cat6A is thicker with a larger bend radius. In a retrofit where existing conduit is already near capacity, that constraint is genuine and occasionally decisive. In a new fit-out where pathways are sized from scratch, it is a non-issue.
Where fibre actually belongs
Fibre is not a premium version of copper. It is the correct answer to a specific set of problems, and the wrong answer to most others.
Fibre is right for:
- Runs beyond 100 metres. Copper stops there. Large floorplates, warehouses, multi-building sites and campus links exceed it regularly.
- Backbone between comms rooms. MDF to IDF, riser runs between floors. Higher capacity, and immune to electromagnetic interference.
- Inter-building links. Anything crossing outdoors or underground.
- Electrically noisy environments. Plant rooms, industrial floors, spaces with heavy machinery.
Fibre is usually wrong for desk drops. Fibre to the desk is meaningfully more expensive than Cat6A and delivers no benefit in a normal office, for two reasons that often get overlooked:
First, fibre carries no power. Every PoE device on your floor — every access point, camera, reader, phone — needs power from somewhere, and copper delivers it down the same cable. Replace horizontal copper with fibre and you have created a separate power problem at every device.
Second, fibre requires transceivers at both ends of every link. These are a real per-port cost that is easy to omit from a comparison and can add substantially to a backbone deployment.
The architecture almost everyone should build
For a typical Dubai office fit-out, the sensible design is not a choice between the two:
Fibre backbone, Cat6A horizontal.
Fibre between comms rooms and between floors, where distance and capacity matter. Cat6A from the comms room to every outlet, where PoE and cost efficiency matter. This is the standard modern architecture and it is standard because it is right for the overwhelming majority of commercial buildings.
The question worth spending design time on is not fibre-versus-copper. It is how many drops, and where.
Density: the number that actually moves your budget
Drop count drives project cost far more than cable category does. Useful planning references:
- General office space: roughly one drop per 100–150 sq ft of usable area
- High-density space (call centres, training rooms, dense open plan): one drop per 50–80 sq ft
- Plus dedicated drops for printers, meeting rooms, and every wireless access point
Access points deserve specific attention in 2026. Wi-Fi 6E and Wi-Fi 7 access points can saturate a 1Gbps backhaul, which means AP drops in particular benefit from Cat6A rather than Cat6. Under-cabling your AP positions is a common and expensive mistake, because those are exactly the drops sitting above a finished ceiling.
Note also that per-drop rates fall as project size rises. A ten-drop job carries mobilisation and minimum-labour costs across very few drops; a five-hundred-drop job in the same building spreads them thin. If you are phasing a fit-out, consolidating cabling into fewer, larger mobilisations is worth real money.
How to compare three bids properly
- Normalise scope first. Write down the ten items listed earlier and mark each bid in or out. Then compare.
- Confirm the cable specification, including fire rating, and confirm it matches what the building requires.
- Ask what test equipment is used and demand certified results as a deliverable, not a claim.
- Check whether a manufacturer warranty is offered — these generally require an installer certified by that manufacturer, and they are meaningful.
- Ask what happens to the per-drop rate at +20% drops. A contractor who has genuinely priced the job can answer immediately.
- The bid that answers all five clearly is usually the one to take, and it is frequently not the lowest number on the page.
Summary
Labour is the cost. Timing is the lever. Cat6A horizontal with a fibre backbone is the right architecture for nearly every Dubai office. Fibre to the desk is a solution looking for a problem in a commercial office, and it takes your PoE with it.
And when quotes diverge sharply, the difference is almost always scope — testing, documentation and comms room work — rather than margin.
