How Much Does Data Cabling Cost in Northern Ireland?

I cannot give you a single number because it depends on too many variables. But I can tell you exactly what drives the cost so you can compare quotes properly and avoid being overcharged or underserved.

What Determines the Price

Number of drops (cable points)

This is the primary cost driver. Each "drop" is one cable run from the patch panel to a wall plate or device location. More drops means more cable, more terminations, more testing time. A 12-drop office costs less than a 48-drop warehouse.

Cable route difficulty

Running cable through an open ceiling void with dropped tiles is fast and cheap. Running through concrete walls, solid floors, fire-rated partitions, or externally between buildings is slower and more expensive. First-fix cabling in a new build (before plasterboard goes up) is cheaper than retrofitting an occupied office.

Cable run length

Most office runs are 15-40 metres. A large warehouse might need 80-90 metre runs approaching the 100-metre Ethernet limit. Longer runs use more cable and take longer to pull.

Patch panel and cabinet

If you already have a network cabinet with space for a new patch panel, the cost is lower. If we need to install a new wall-mounted cabinet (or floor-standing rack for larger installations), that adds hardware cost.

Testing and certification

Every cable run should be tested with a cable certifier (not just a continuity tester). This confirms the cable passes performance standards for its category. Test results are documented and provided. This adds a small cost per point but is essential for warranty and future troubleshooting.

Containment and tidy finish

Cable trunking, conduit, or tidy routing within ceiling voids all add time. If you need a visible professional finish with surface-mounted trunking (common in older buildings without accessible ceiling voids), that costs more than hidden runs above ceiling tiles.

Rough Cost Ranges (Northern Ireland, 2026)

These are typical ranges for Cat6 structured cabling. Actual quotes vary based on the factors above.

• Small office (8-12 drops) with existing cabinet and accessible ceiling void: lower end of scale
• Medium office (20-30 drops) with new cabinet, mixed cable routes: mid range
• Warehouse or industrial (30-50+ drops) with long runs, external routes, or difficult access: higher end
• Single drops added to existing installation: lower per-point cost if the cabinet and containment already exist

I am not publishing fixed prices because every site is different and I would rather quote accurately after a survey than give you a number that turns out to be wrong. The site survey is free.

What to Ask Before Accepting a Cabling Quote

1. Is it Cat5e or Cat6? (New runs should be Cat6)
2. Is a patch panel included, or just loose cables?
3. Is each cable run tested and certified?
4. Are test results documented and provided?
5. Is the termination at both ends included (patch panel and wall plate)?
6. Are cables labelled at both ends?
7. Is containment (trunking/management) included in the price?
8. Is there a warranty on the installation?
9. Is the quote fixed, or are there potential extras?
10. Who supports it after installation if there is a fault?

What Makes a Cheap Quote Cheap

Be cautious of very low quotes. Common shortcuts that reduce cost but cause problems later:

• Cat5e instead of Cat6 (saves a few pounds per run but gives you less headroom)
• No patch panel (cables plugged directly into switch with no management)
• No testing (how do you know the cable works properly?)
• No labelling (impossible to trace faults later)
• No documentation (next engineer has to start from scratch)
• No containment (cables hanging loose in ceiling voids)

Cabling Is Only Part of the Setup

Good cabling helps, but the network still needs to be designed, documented and supported. We can install Cat5e or Cat6 cabling, then help maintain the Wi-Fi, switches, CCTV, VoIP phones, routers and firewall that depend on it.
