Why In-House IT Teams Should Avoid Data Cabling Installations

Fri, 06 Jun 2025 13:44:27 GMT

The Hidden Costs, Compliance Risks, and Safety Dangers of DIY Network Cabling

In today’s increasingly connected world, reliable data cabling installation is critical to the performance and safety of any commercial or educational facility. While your in-house IT team may be skilled in software deployment, device support, or general networking, assigning them to handle structured cabling can introduce serious risks — both financially and from a health and safety compliance perspective.

Now, I completely understand the appeal of doing it internally.

It feels like a cost-saving measure: use the people already on payroll rather than hire a third party. But in reality, DIY cabling installations often lead to substandard performance, system instability, and even legal liability due to building code violations or exposure to health hazards like asbestos.

In this article, we’ll explore the dangers of in-house cabling , how it can cost you more in the long run, and why certified professionals remain the safest and most cost-effective solution.

Here’s why data cabling should always be left to experienced professionals — and the risks you take when trying to manage it in-house.

1. Lack of Industry-Specific Skills and Experience

Your IT department may be highly skilled in managing software, troubleshooting networks, or deploying end-user devices — but data cabling is a different world entirely. Professional cabling installers undergo specific training on cable types, containment systems, bend radii, termination standards, and building infrastructure planning.

Installing data cabling is not just about routing cables from point A to point B. It involves understanding of:

Standards such as TIA/EIA-568 and ISO/IEC 11801
Fire safety and containment
Cable segregation from power sources
Cable bend radius and tensile strength
Performance limitations of different cable types

When these elements are not correctly implemented, the installation may result in:

Poor cable management
Signal interference from improper separation from power
Excessive cable stress and damage
Use of incorrect cable types for specific environments (e.g., external, plenum, or fire-rated)

The result? A cabling system that may appear functional but performs far below optimal — or worse, fails intermittently and unpredictably.

2. Lack of Professional Test Equipment

Installing data cabling is only half the job. Testing it properly is what certifies that the installation meets performance expectations and manufacturer warranties.

In-house IT teams rarely have access to calibrated, manufacturer-approved certification testers such as those from Fluke Networks or AEM. These tools are essential for:

Verifying signal integrity (NEXT, RL, attenuation, etc.)
Ensuring performance at the correct standard (e.g., Cat6a/10G)
Generating detailed test reports for warranty and compliance
Identifying installation faults before they become user-facing problems

Owning and maintaining this kind of test equipment is a significant investment — and it forms part of what you're paying for when you hire a trusted, certified cabling professional. These devices require regular calibration, firmware updates, and proper usage to produce accurate, standards-compliant results.

Without proper testing, faults may remain hidden — only surfacing during critical use or system expansion. And once user issues begin, diagnosing faults without a certified tester is like shooting in the dark.

3. Health & Safety and Compliance Risks

Beyond performance, there are significant legal and safety concerns. Structured cabling work in commercial or educational buildings must follow stringent regulations and safety standards, including:

BS7671 Wiring Regulations – Covering electrical safety, segregation of services, and mechanical protection
CPR (Construction Product Regulation) Ratings – Governing the fire performance of cables in occupied buildings
Mechanical Support Requirements – Preventing cable sag, damage, and hazards through correct containment and fixings

Untrained staff may unknowingly:

Install non-compliant, flammable cables in escape routes
Route cabling through restricted areas (e.g., ducting meant for high voltage)
Leave cables unsupported, creating trip or fire hazards
Void insurance or building compliance through improper installations

These are not minor oversights — they could lead to legal consequences, failed inspections, or significant safety risks for occupants. Using compliant materials and proven installation methods isn’t optional; it’s the law.

4. Cost of Mistakes Can Be Higher Than Doing It Right

Attempting to “save money” by keeping installations in-house often leads to greater costs in the long run. Some common scenarios:

Rework – Poor installations needing full replacement to meet standards
Downtime – Faulty cabling affecting business-critical systems
Voided Warranties – Manufacturers rejecting claims due to incorrect installation or testing
Fines or Delays – Non-compliance with fire safety or electrical standards

When a professional installer is brought in after-the-fact, the cost includes removal, remediation, and often reinstallation — far exceeding what it would have cost to do it properly from the beginning.

A certified installer also provides clear documentation, including test results, cable schematics, and warranty paperwork that protects you and ensures future serviceability.

5. Fire-Stopping and Asbestos Risks: Safety Hazards You Can’t Afford to Overlook

Beyond the technical risks and performance issues, health and safety hazards are perhaps the most serious concern when unqualified staff undertake structured cabling work — particularly when penetrating walls, floors, or ceilings.

Improper Fire-Stopping Repairs

Data cabling often requires running cables through compartment walls or fire-rated barriers. These are part of your building's passive fire protection system , designed to contain fire and smoke during an emergency.

Untrained teams may:

Drill through fire-rated walls or floors without proper fire sleeves or seals
Fail to correctly reinstate the fire-stopping materials after installation
Use non-compliant sealants or backboxes that don’t meet fire rating requirements

This puts your entire building at risk of non-compliance with fire regulations — and worse, puts lives in danger if a fire occurs.

Accidental Asbestos Disturbance

Many commercial and educational buildings constructed before the year 2000 may still contain asbestos-containing materials (ACMs) — especially in ceilings, risers, floor voids, and riser cupboards where data cabling is often installed.

Certified cabling professionals are trained to:

Identify high-risk materials
Request and review the Asbestos Register before any works begin
Halt works immediately and escalate appropriately if suspected ACMs are found

In-house IT staff are unlikely to have this training — and may unknowingly disturb asbestos during installation, releasing hazardous fibres into the air. This is not just a compliance issue — it’s a serious health risk with long-term consequences.

6. Structured Cabling is an Investment — Not Just a Job

Think of your cabling as your digital infrastructure — the foundation on which your network, security systems, telephony, and AV all depend. A bad cabling job is like building a skyscraper on sand. It may seem fine at first, but when pressure mounts, it won’t hold.

Certified installers:

Use brand-approved components
Follow proper installation guidelines
Provide end-to-end test certification
Future proof the design with scalability in mind

In contrast, internal teams may not plan for growth, add proper labelling, or even document the installation — making troubleshooting or expansion a nightmare for future teams.

Conclusion: Stick to What You Know — and Let Professionals Handle the Rest

Your IT team is invaluable in managing your organisation’s technology, but they shouldn't be burdened with infrastructure-level work like data cabling installation. Trusting certified cabling professionals ensures your network is fast, compliant, and future-proof.

Whether it’s a new installation, an upgrade to Cat6a/10G, or a fibre optic backbone — you only get one chance to get the foundation right.

What is a Data Engineer? A Day in the Life of a Data Cabling Engineer: Fibre Optic, Cat6a, and Network Installation Services Across the UK

At Active Data Installations (ADI), our engineers are the backbone of our operation. Their days are filled with a variety of tasks that keep our clients connected, secure, and prepared for the future. From schools and hospitals to retail spaces and offices, our engineers work across a wide range of environments, delivering high-quality network infrastructure solutions with professionalism and technical expertise.

In this blog, we’ll take you through a typical day in the life of an ADI data cabling engineer, highlighting the skills, responsibilities, and challenges they face as part of a communications installation company.

Early Start, Big Impact

The day often begins early. Our engineers typically check in with the office or review their schedules for the day ahead. Depending on the job, this might involve a bustling hospital, a vibrant school, or a corporate office, every project is unique and demands their full attention and expertise.

Upon arrival on site, the engineer will liaise with the client or site contact, confirming job scope, health and safety requirements, and any potential access issues. On building sites or refurbishments, this also involves signing in, checking RAMS (Risk Assessments and Method Statements), and ensuring all PPE is worn and safety procedures followed.

Installation Work: Copper, Fibre and More

Much of the work involves the installation and termination of copper cabling—typically Cat6 or Cat6a. With the ability to interpret technical drawings, they ensure every installation aligns perfectly with project specifications. Our engineers are experienced in running cables through trunking, containment systems, suspended ceilings, or raised floors, making neat and efficient routes for network infrastructure. They’re often seen carefully dressing and securing cables in containment to maintain a clean and professional appearance.

Termination and testing follow, with the engineer connecting cables into data outlets or patch panels, using specialist tools to ensure each connection meets industry standards. They’ll also label and document each cable to ensure future maintenance or additions can be carried out easily.

Fibre optic installation is another crucial part of the job. This involves running and terminating fibre cables, often using fusion splicing techniques, and testing links with OTDRs or power meters. With high-speed connectivity demands increasing, our engineers ensure the networks they install are future-ready and fully certified.

Cabinet Remediations and Upgrades

Many of our jobs involve work in data cabinets—whether installing a new one or carrying out a remediation to tidy and improve an existing setup. Cabinet work requires attention to detail, patience, and problem-solving. Engineers might re-route messy patch leads, replace faulty switches, install new fibre trays, or reconfigure the layout to improve airflow and cable management.

Properly managed cabinets not only look more professional, but they also ensure better performance and make troubleshooting far easier. Before and after photos are often taken, showcasing the improvement and providing clients with a record of work completed.

What is Data Cabling?

Introduction

The question I'm always asked when I tell people my profession is "What is Data cabling?"

Data cabling is the physical medium that connects and enables communication between devices within a network. Whether it’s your computer connecting to the internet, a phone system transmitting calls, or a security camera streaming footage, data cabling is the unseen infrastructure making it all possible.

At its core, data cabling involves structured wiring systems that transmit data in the form of electrical signals or light pulses. These systems are designed to ensure high-speed, reliable, and secure communication. Think of it as the digital equivalent of a Motorway system—just as roads connect cities and towns, data cabling connects devices, servers, and networks to ensure smooth data flow.

What is Data Cabling?

Data cabling, often referred to as structured cabling, is the physical network infrastructure that connects your devices to the internet or internal networks. It includes:

Copper cabling (e.g., Cat5e, Cat6, Cat6a): typically used for shorter distances in offices, schools, and homes.

Fibre optic cabling : used for high-speed, long-distance connections — think data centres, large campuses, or backbones between telecom cabinets.

It’s installed in walls, floors, ceilings, and cabinets — carefully routed to ensure optimal performance and minimal disruption.
