FAQs – Data Cabling for Commercial Buildings

Q: What is structured cabling, and why does it matter?

Structured cabling is a planned system of network wires and sockets that keeps your internet, phones, and security running smoothly. It makes your site easier to manage, scale, and troubleshoot. We install to high standards – cleanly routed, labelled, and fully certified.

Yes – especially in commercial settings. Your data cabling must meet standards such as:

  • BS EN 50173 & ISO/IEC 11801 (cable performance)
  • BS7671 (IET Wiring Regs) if linked to power
  • TIA/EIA (testing standards)

We handle all compliance and provide Fluke test reports and documentation for audits or insurers.

  • Full handover packs with diagrams, labels, and test data
  • NICEIC (link https://niceic.com/), CHAS (link https://www.chas.co.uk/), and REFCOM (link https://www.refcom.org.uk/) accredited engineers
  • Fluke-certified testing for proven performance
  • Disruption-free install options (phased or out-of-hours)
  • End-to-end service – from design to emergency fixes

Yes. Business-grade Wi‑Fi relies on cables for access points, switches, and routers. A weak cabling setup means slow or unreliable wireless too. We build hybrid systems that make both Wi‑Fi and wired connections strong and stable.

We’ll recommend the best fit during your site survey, based on:

  • Cat5e: Now outdated
  • Cat6: Standard for general office use
  • Cat6a: Ideal for fast, PoE systems like VoIP or CCTV
  • Fibre: Best for long runs or ultra-high-speed networks
    We balance cost-effectiveness with futureproofing.

Not if we can help it. We offer:

  • Phased installs
  • Out-of-hours work
  • Timelines agreed upfront


We’re efficient, tidy, and work around your hours.

  • Emergency fault repairs
  • Patching and changes for new layouts
  • Re-testing for office moves or upgrades

We also keep your install details on file – so future support is faster.
