Data Cabling Installation Cost: UK Cat6 Pricing Guide 2026

Per-Point Pricing (Fully Installed and Tested)

• Cat6 data point — £80 to £150 per point. Includes Cat6 U/UTP cable (305m box at £80 to £120 trade), single-gang faceplate with Cat6 module, patch panel port termination, and channel test certification. Price varies with cable run length and building access.
• Cat6a data point — £100 to £200 per point. Cat6a S/FTP cable is thicker and more expensive (305m box at £150 to £250 trade). Requires Cat6a-rated modules and patch panel. Recommended for 10 Gigabit Ethernet and future-proofing.
• Double data point (two cables to one faceplate) — £140 to £260 per position. A dual-port faceplate with two independent cable runs back to the patch panel. Common at desk positions where a PC and VoIP phone both need wired connections.
• Volume pricing (50+ points) — £65 to £120 per Cat6 point, £85 to £160 per Cat6a point. Larger projects benefit from economies of scale in cable purchasing, containment installation, and testing efficiency.

• Horizontal cabling — the Cat6 or Cat6a cable runs from the comms cabinet to each data point. Maximum 90 metres for permanent link, 100 metres for channel (including patch leads). Cable is sold in 305m boxes — a box typically serves 8 to 15 data points depending on run lengths.
• Patch panel — mounts in the comms cabinet and provides the termination point for all horizontal cables. A 24-port Cat6 patch panel costs £30 to £60 trade. Cat6a patch panels cost £50 to £100. Choose modular patch panels for flexibility.
• Comms cabinet — wall-mounted cabinets (6U to 12U) cost £80 to £200. Floor-standing cabinets (22U to 42U) cost £250 to £600. The cabinet houses the patch panel, network switch, router, and other networking equipment. Include a shelf, fan tray, and power distribution unit (PDU).
• Faceplates and modules — single or double-gang faceplates with snap-in Cat6 modules at each data point. Budget £5 to £12 per faceplate with modules. Use colour-coded modules to distinguish data, voice, and WiFi connections.
• Containment — cable tray, basket, trunking, or conduit to support and protect cable runs. Mini-trunking for visible runs in offices costs £1 to £3 per metre. Cable basket in ceiling voids costs £5 to £15 per metre. This is often the most variable cost element.
• Patch leads — short cables connecting the patch panel to the network switch, and from the faceplate to the device. Budget £3 to £8 per patch lead. Typically two per data point (one at each end).

• AP cable run — each WiFi access point needs a Cat6 cable from the comms cabinet to the AP mounting position (typically ceiling-mounted). Cost: £80 to £150 per AP position including cable, termination, and testing.
• PoE power — modern WiFi access points are powered via PoE (Power over Ethernet), receiving both data and power through the same Cat6 cable from a PoE network switch. This eliminates the need for a separate power supply at each AP position, reducing installation cost.
• Coverage planning — typical coverage is one AP per 50 to 100 m² in an office environment, depending on wall construction and user density. A 500 m² office might need 6 to 10 access points.

• Multimode fibre (OM3/OM4) — £2 to £5 per metre for 4-core cable. Suitable for runs up to 300 metres at 10 Gbps. The standard choice for inter-floor links within a single building.
• Single-mode fibre (OS2) — £1.50 to £4 per metre for 4-core cable. Required for runs exceeding 300 metres or between separate buildings. Supports distances of several kilometres.
• Fibre termination and testing — fusion splicing and OTDR testing requires specialist equipment. Budget £200 to £500 per fibre link (each end terminated and tested). Some installers subcontract fibre termination to specialists.
• Fibre patch panels and SFP modules — fibre patch panels cost £30 to £80 each. SFP (Small Form-factor Pluggable) modules for the network switches cost £15 to £50 each. Budget one at each end of every fibre link.

• Channel test — tests the complete link from patch panel to faceplate including patch leads. Measures insertion loss, return loss, NEXT (near-end crosstalk), FEXT (far-end crosstalk), and propagation delay. A Fluke DSX-5000 or equivalent certifier is the industry standard.
• Permanent link test — tests the fixed cabling only (excludes patch leads). More commonly used as it tests the installed infrastructure independently of the patch leads, which may be replaced over time.
• Certification report — each cable run gets an individual pass/fail result against the relevant standard (Cat6 = TIA-568-C.2 Class E, Cat6a = TIA-568-C.2 Class EA). The full set of test reports is provided to the client as proof of compliance.
