How to Plan Your Office Network Cabling Before You Move

An office move is one of the most complex logistical challenges a business can face. There are leases to negotiate, furniture to arrange, staff to relocate, and clients to inform. Amid all this upheaval, one element that often receives far too little attention is network cabling — the physical infrastructure that connects every computer, phone, printer, and server in your new space.

Poor network cabling planning is one of the most common causes of IT problems after an office move. Businesses that rush this step often end up with unreliable connections, insufficient data points, cables trailing across floors, and an infrastructure that cannot support future growth. Worse, retrofitting cabling after you have moved in is significantly more expensive and disruptive than getting it right from the start.

This guide walks you through every aspect of planning your office network cabling before you move, ensuring your new space is connected, reliable, and ready for the future.

The consequences of poor cabling planning are rarely immediate. In most cases, businesses do not realise the extent of the problem until weeks or months after the move, when intermittent network dropouts begin affecting productivity, when expanding to accommodate new hires proves impossible without costly rework, or when a single point of failure brings down the entire network during a critical trading period. Unlike software problems, which can often be resolved remotely, cabling issues require physical intervention — engineers on site, ceiling tiles removed, desks displaced, and business operations disrupted.

What makes this particularly frustrating is that almost all of these issues are entirely preventable. A well-designed cabling infrastructure, installed by qualified engineers before the office is occupied, costs a fraction of what remedial work costs after the fact. The key is treating network cabling as a first-class concern in your move planning, not an afterthought to be squeezed in around the furniture installation.

Why Network Cabling Matters More Than You Think

In an age of wireless everything, you might wonder whether physical network cabling still matters. The answer is an emphatic yes. While Wi-Fi is essential for mobile devices and meeting rooms, the backbone of any reliable business network remains structured cabling. Your servers, desktop workstations, IP phones, printers, wireless access points, and CCTV cameras all depend on physical cable connections.

Wireless networks are shared bandwidth environments — the more devices connected, the slower each one becomes. Physical cabling provides dedicated bandwidth to each connected device, delivering consistent performance regardless of how many other devices are on the network. For tasks that demand reliability and speed — VoIP calls, video conferencing, large file transfers, and cloud application access — cabled connections are vastly superior.

Furthermore, every wireless access point in your office connects back to the network via a cable. If your cabling infrastructure is poorly designed, your Wi-Fi performance will suffer too, no matter how expensive your access points are.

The Hidden Cost of Inadequate Cabling

When businesses cut corners on network cabling, the consequences manifest gradually — intermittent connection drops during video calls, file transfers that stall without explanation, printers that sporadically go offline, and VoIP calls plagued by jitter and latency. These issues are maddeningly difficult to diagnose because they appear random, and IT teams often spend weeks chasing software or hardware faults before discovering that the root cause is a poorly terminated cable or substandard cabling that cannot sustain the required data rates under load.

The productivity cost is substantial. Research from industry bodies consistently shows that network downtime costs UK SMEs an average of £3,000 to £5,000 per hour when factoring in lost productivity, missed client communications, and delayed transactions. Even intermittent issues that do not constitute full downtime erode productivity — staff learn to work around unreliable connections, switching to mobile hotspots, walking to other desks, or simply waiting. Over weeks and months, these small frustrations compound into significant lost output.

There is also a reputational dimension. Client-facing video calls that freeze or drop reflect poorly on your business. If your team cannot reliably access cloud-based CRM, project management, or accounting systems, client responsiveness suffers. In competitive markets, the businesses that operate most smoothly behind the scenes are the ones that win and retain clients.

Starting Your Cabling Plan: The Site Survey

The first and most critical step in planning your office cabling is conducting a thorough site survey of your new premises. This should happen as early as possible — ideally before you sign the lease, or at least before any fit-out work begins.

A proper site survey examines the physical layout of the building, identifies where your comms room or server cabinet will be located, maps out the routes cables will need to follow, and notes any structural obstacles such as fire walls, asbestos, or listed building restrictions. The survey should also assess the existing cabling infrastructure, if any, to determine whether it can be reused or needs replacing.

Key Questions for Your Site Survey

Where will the comms room be located? This should be a secure, well-ventilated space with adequate power supply. Ideally, it should be centrally located within the building to minimise cable run lengths. Is there existing containment (trunking, conduit, or ceiling voids) that can be used for cable routes? What is the maximum distance from the comms room to the furthest desk position? Structured cabling standards limit copper cable runs to 90 metres. Are there any building regulations or landlord requirements that affect cabling installation?

Working with Landlords and Building Management

Before any cabling work can begin, you will need to engage with your landlord or building management company to understand the rules and restrictions governing infrastructure work in the premises. Most commercial leases include provisions about alterations to the building fabric, and cabling installation — which may involve drilling through walls, routing cables through risers, and installing containment in ceiling voids — typically falls within these provisions.

Request any available building drawings or plans, which can significantly speed up the planning process. Ask about shared risers between floors, existing containment routes, and any areas where access is restricted. If the building has multiple tenants, there may be shared infrastructure such as a building-wide fibre backbone or a managed entry point for internet services. Understanding these elements early prevents delays and unexpected costs once the installation is under way. Some landlords also require that all cabling work be carried out by approved contractors, so clarify this before appointing your own installer.

Choosing the Right Cable Standard

The type of cable you install will determine the maximum speed and reliability of your network for years to come. Getting this decision right is crucial because replacing cabling is expensive and disruptive.

Cable Type	Max Speed	Max Distance	Recommended For
Cat5e	1 Gbps	100m	Budget installations (not recommended for new builds)
Cat6	10 Gbps (up to 55m)	100m	Standard office installations
Cat6a	10 Gbps	100m	Future-proof installations (recommended)
Fibre (OM3/OM4)	40-100 Gbps	300m+	Backbone links, data centres, long distances

For most UK office environments in 2026, we strongly recommend Cat6a as the minimum standard for new installations. While Cat6 is adequate for current 1 Gbps requirements, Cat6a supports 10 Gbps across the full 100-metre distance and will comfortably handle network demands for the next 15 to 25 years. The cost difference between Cat6 and Cat6a is typically 15 to 20 per cent — a modest premium for significantly greater future-proofing.

For backbone connections between floors or between the comms room and distribution points, fibre optic cabling is the standard choice. Fibre offers vastly greater bandwidth over longer distances and is immune to electromagnetic interference.

Shielded Versus Unshielded Cable

You may encounter references to shielded (STP or F/UTP) and unshielded (UTP) cable when specifying your installation. In most UK office environments, unshielded Cat6a cable is perfectly adequate and is the more commonly installed option. Shielded cable provides additional protection against electromagnetic interference (EMI), but it requires shielded connectors, shielded patch panels, and proper earthing throughout the installation to deliver its full benefit. If the shielding is not properly bonded and grounded, it can actually introduce more interference than it prevents.

Shielded cable is typically recommended only in environments with significant sources of EMI, such as offices located near heavy electrical machinery, manufacturing areas, or medical imaging equipment. For standard commercial office spaces, a quality unshielded Cat6a installation will deliver reliable 10 Gbps performance without the added complexity and cost of a shielded system. Discuss your specific environment with your cabling contractor, who can advise based on a site assessment.

Power over Ethernet Considerations

Modern offices increasingly rely on Power over Ethernet (PoE) to deliver both data and electrical power over a single cable. Wireless access points, IP telephones, security cameras, and door access controllers can all be powered via PoE, eliminating the need for separate power sockets at each device location. This is particularly valuable for ceiling-mounted devices where running a separate power cable would be impractical or costly.

However, PoE places additional demands on your cabling infrastructure. PoE generates heat within the cable, and when cables are tightly bundled in containment, this heat can accumulate and degrade performance. Cat6a cable handles PoE better than Cat6 because its superior construction and thicker conductors dissipate heat more effectively. If you plan to deploy PoE extensively — as most modern offices should — this is another compelling reason to specify Cat6a throughout your installation.

How Many Data Points Do You Need?

One of the most common mistakes businesses make is installing too few data points. The cost of pulling an extra cable during initial installation is minimal compared to the cost of adding one later. The general rule of thumb is to install at least double the number of data points you think you need.

For a practical example, consider an office with 50 desk positions. At a minimum, you would want 100 data points at desks (two per desk), plus points for 6 to 10 wireless access points, 4 to 6 printers, 3 to 5 meeting rooms with 2 points each, CCTV cameras, and at least 15 to 20 spare points for future use. That totals approximately 140 to 150 data points — far more than the 50 a business owner might initially assume.

Designing Your Comms Room

The comms room — sometimes called the server room, IT room, or MDF (Main Distribution Frame) — is the heart of your network. Every cable in the building ultimately terminates here, and the quality of this room directly affects the reliability of your entire network.

Your comms room needs adequate space for your server racks or cabinets, with room to access the front and rear of each cabinet. It needs dedicated, clean power with ideally an Uninterruptible Power Supply (UPS) to protect against mains fluctuations and brief outages. Temperature control is essential — a comms room that overheats will cause equipment failures. A small split-system air conditioning unit is usually sufficient for a standard SME comms room.

Security is also critical. The comms room should be locked, with access limited to authorised personnel. It should never be used for general storage — we have seen comms rooms used to store Christmas decorations, cleaning supplies, and even bicycles, all of which create fire risks and restrict access during emergencies.

Cable Management and Labelling

It is astonishing how quickly a well-organised comms room can descend into chaos without proper cable management. Every cable should be neatly routed through cable management panels, bundled where appropriate, and — most importantly — labelled at both ends.

A clear labelling scheme saves enormous amounts of time when diagnosing faults, making changes, or expanding the network. Each cable should be labelled with a unique identifier that corresponds to a documented floor plan showing the exact location of each data point. This documentation is as important as the cabling itself — without it, tracing a faulty cable can take hours instead of minutes.

Developing a Naming Convention

A well-designed naming convention is the foundation of effective cable management. A typical approach uses a hierarchical structure: a code for the floor, followed by a code for the zone or area within the floor, followed by the individual data point number. For example, a label reading 2F-NW-014 might indicate Floor 2, North West zone, data point 14. The exact format matters less than consistency — whatever scheme you choose, apply it rigorously to every cable, every patch panel port, and every wall plate throughout the building.

Labels should be machine-printed, not handwritten. Handwritten labels fade, smudge, and become illegible within months, particularly in the warm environment of a comms room. Use a dedicated cable label printer with self-laminating labels designed for the purpose. Each cable should be labelled at both the patch panel end and the wall plate end, and the label should be visible without needing to move or manipulate the cable.

Documentation as a Living Asset

Beyond physical labels, your cabling installation should be accompanied by comprehensive documentation that includes a floor plan showing the exact location of every data point, a schedule mapping each cable identifier to its patch panel port and switch port, test results for every cable, and details of the containment routes used. This documentation should be maintained as a living document, updated every time a change is made. Store it digitally in a shared location accessible to your IT team, and keep a printed copy in the comms room for quick reference during fault diagnosis.

Many businesses neglect documentation, treating it as paperwork rather than a critical operational asset. The reality is that accurate, up-to-date cabling documentation can reduce fault resolution times by 60 to 80 per cent. When a user reports that their connection is down, your IT team can look up the exact cable, trace it from patch panel to wall plate, and identify the fault in minutes rather than hours. Without documentation, they are left physically tracing cables through ceiling voids — a time-consuming and frustrating exercise that often requires two people and a significant disruption to the office.

Wireless Access Point Placement

Your wireless network depends entirely on your cabled infrastructure. Each wireless access point requires a cable back to the network switch, and ideally should be powered via Power over Ethernet (PoE) to avoid the need for separate power sockets in ceiling voids.

Access point placement should be planned using a professional wireless survey that considers the physical layout of the office, wall materials, interference sources, and expected device density. As a rough guide, a single enterprise-grade access point can typically serve 25 to 30 concurrent devices in an open-plan environment, but this varies significantly based on building construction and usage patterns.

Coordinating with Your Fit-Out Team

Network cabling installation needs to be coordinated carefully with the overall office fit-out programme. Cables need to be installed before ceiling tiles go up, before partition walls are completed, and before floor coverings are laid. If the cabling contractor arrives after the plasterers and painters have finished, the cost and disruption increase dramatically.

The ideal sequence is: structural work and mechanical/electrical first, then cabling containment and cable pulling, then partitions and ceilings, then testing and termination, and finally desk installation and device connection. Work with your fit-out project manager to ensure the cabling contractor has access at the right time.

Testing and Certification

Once your cabling is installed, every single cable should be tested and certified before the network goes live. Professional cable testing uses a Fluke or equivalent tester to verify that each cable meets the performance standard it was installed to (Cat6, Cat6a, etc.) across all parameters including wire mapping, length, insertion loss, and crosstalk.

Your cabling contractor should provide you with a full set of test results for every cable, along with a certification that the installation meets the relevant standards (typically BS EN 50173 in the UK). This documentation is valuable both for troubleshooting and as evidence of quality if you ever need to make a warranty claim.

Insist on 100% testing — not just a sample. A single untested cable that turns out to be faulty can cause intermittent problems that take hours to diagnose.

Understanding What Testing Reveals

Professional cable testing goes far beyond simply confirming that a signal passes from one end to the other. A comprehensive test measures wire map (verifying that each conductor is connected to the correct pin at both ends), cable length (ensuring it does not exceed the 90-metre permanent link limit), insertion loss (signal attenuation over the cable length), return loss (signal reflection caused by impedance mismatches), and near-end and far-end crosstalk (interference between wire pairs within the cable). A cable can pass a simple continuity test while still failing to meet Cat6a performance standards due to excessive crosstalk or insertion loss — and that cable will cause intermittent, hard-to-diagnose problems under real network traffic.

Warranty and Manufacturer Backing

Certification also establishes your warranty entitlements. Most reputable cabling manufacturers offer extended warranties of 15 to 25 years on their structured cabling systems, but these warranties are contingent on the installation being carried out by an accredited installer and every cable passing certification testing. Without test results, you have no warranty — and no recourse if cabling failures cause business disruption years down the line. Ensure your installer is accredited by the cabling manufacturer they are using and that they provide you with digital copies of all test results, stored securely alongside your cabling documentation for future reference.

Planning Your Internet Connectivity

Your internal cabling is only as useful as the internet connection feeding it. As part of your move planning, research the available broadband and leased line options at your new premises. Availability varies enormously across the UK, and what was available at your old office may not be available at the new one.

For businesses with more than 10 users, we recommend a dedicated leased line rather than standard broadband. Leased lines provide symmetrical speeds (the same upload and download rate), guaranteed bandwidth, and an SLA with financial penalties if the provider fails to meet their commitments. Standard broadband, even full-fibre FTTP, is a shared service with no guarantees.

Order your new internet connection as early as possible. Leased line installations in the UK typically take 60 to 90 working days from order to delivery, and this timeline can extend significantly if Openreach needs to install new infrastructure. Starting this process late is one of the most common causes of IT disruption during office moves.

A Timeline for Your Move

Bringing all of these elements together requires careful timing. Here is a recommended timeline for the IT and cabling elements of your office move.

At 12 weeks before the move, conduct the site survey and finalise the cabling design. Order your internet connectivity. At 10 weeks, appoint your cabling contractor and agree the installation schedule with your fit-out team. At 8 weeks, begin cabling installation (containment and cable pulling). At 6 weeks, complete cabling termination and begin testing. At 4 weeks, install network equipment (switches, wireless access points, firewall) and configure the network. At 2 weeks, conduct final testing, connect a sample of workstations, and verify all services. On moving day, connect all remaining devices and provide on-site support for staff. During the first week after the move, address any snags, optimise wireless coverage, and confirm all systems are working correctly.

This timeline assumes a straightforward move with good coordination between all parties. Complex moves involving multiple floors, phased relocations, or listed buildings may require a longer lead time.
