The short version
Most businesses only set up a new office once every several years, so the choice of cabler is made with little to compare against. The cabling then outlasts the lease on most of the equipment plugged into it.
Hire a data cabling company with a registered cabler on the team, that tests and documents its work, and that will talk to your builder and electrician directly. Then brief them properly. A clear written brief gets you quotes you can compare, and it is where most of the future-proofing happens.

Which companies specialise in data wiring for a new office?
Office data wiring is done by data cabling companies, sometimes called structured cabling or communications contractors. Some electrical contractors also hold cabling registration. General IT providers often subcontract the cabling, which is fine if you know who is actually turning up.
For a new office, the useful traits are:
- A registered cabler on the team. The ACMA advises making sure the cabler you choose is registered, and a registered cabler can show you their registration card. Ask for it.
- Testing and documentation as standard. Every outlet tested, labelled at both ends, and recorded on a floor plan you keep. If this is an optional extra, keep looking.
- Experience working inside a fit-out programme. The cabler has to fit between other trades, before ceilings close and after the electrician’s rough-in. A company that is used to builders and project managers will ask about the programme before you mention it.
- Someone who looks after what plugs in. Cabling ends at the patch panel. If the same company installs the switching, Wi-Fi, cameras or door access, fewer questions fall between contractors.
If you are searching for a data cabling company in Melbourne, the same list applies. Location matters mostly for site visits during the build and support afterwards.
What to ask before hiring a cabler
These questions sort out most of the field quickly.
- Who will be on site, and are they registered or supervised by someone who is?
- How do you test each outlet, and what do we get at handover?
- Will you give us a signed statement that the work complies with the Wiring Rules? The ACMA says a registered cabler provides one at the end of the work.
- Will you deal with our builder and electrician directly about pathways, power and the comms room?
- What have you assumed about ceiling access, existing containment and working hours?
- What is excluded from the price?
- Who supplies and installs the rack, the switches and the access points?
- If an outlet fails a test or a move is needed later, how is that handled?
Pay attention to how they answer the testing question. A cabler who tests properly will describe it without being prompted.
What a good office data cabling quote states
Ask every company to quote against the same brief. Then check each quote states the following.
| Item | What it should say |
|---|---|
| Outlets | How many, which rooms, single or double |
| Cable category | Cat6 or Cat6A, and where each is used if mixed |
| Rack and patching | Rack size, patch panels, cable management, power |
| Wireless and devices | Cable runs for access points, cameras and door hardware |
| Pathways | What containment exists, what is new, and who installs it |
| Testing | Every link tested, with results supplied |
| Documentation | Labelling, outlet floor plan and test reports at handover |
| Assumptions | Ceiling access, working hours, site readiness |
| Exclusions | Anything you might assume is included but is not |
A quote that only gives a total is hard to compare, and harder to hold anyone to.
What commercial data cabling system design should start from
The cabler designs the system, but they design it from what you tell them. Before asking for quotes, write down:
- A floor plan with desks, meeting rooms, reception and any shared areas marked.
- Where printers, screens, phones and any fixed equipment will go.
- Where you want Wi-Fi coverage, including any outdoor or warehouse areas.
- Which doors you want controlled and where cameras might go, even if they come later.
- Where the comms rack can live, and whether that space has power and airflow.
- How many people you expect in a few years, not only on move-in day.
The more of this you settle before the quote, the fewer variations you pay for during the build.
How do we future-proof our office cabling infrastructure?
Future-proofing is mostly cheap decisions made early.
Spare outlets. Put more outlets in than today’s desk plan needs, particularly in open-plan areas and meeting rooms. Running an extra cable while the ceiling is open costs far less than coming back once it is closed and the desks are in.
Cable category. Cat6 is the practical default for many offices. Cat6A is worth considering where the fit-out has a long life, where higher-speed links to access points are likely, or where many devices draw power over the cable. Mixing the two is often sensible. Cat6 vs Cat6A covers the trade-offs.
Rack space. Leave empty space in the rack and spare ports on the patch panels. A rack that is full on day one makes every later change a project.
Cabling for devices, not only desks. Access points, cameras, door readers and screens all need cable. Run it during the fit-out even if the devices come later, and label it as spare. Retrofitting cable to a ceiling-mounted camera after handover is a common and avoidable cost.
Documentation. A labelled floor plan, a rack layout and test results make every future change faster. Keep them with the lease documents, not in one person’s inbox.
Red flags when choosing an office data cabler
- They will not visit the site or look at the floor plan before pricing.
- The quote has no outlet count or cable category.
- Testing and documentation are missing or priced as optional.
- They are vague about who will do the work or whether that person is registered.
- They assume nothing about access points, cameras or doors, so those come back as variations.
- They want to start before the electrician and builder have agreed pathways and the comms room location.
None of these prove a company is poor. Together they usually predict variations, rework or a rack nobody can trace later.
Helpful starting points
Kookaburra Comms is based in Frankston and installs data and fibre cabling across Melbourne and Victoria, with a registered cabler on the team and testing, labelling and as-built documentation on every job. For a whole new site, commercial fit-out communications covers the cabling with the network, internet and security around it. If the building is new rather than an existing tenancy, read communications in a new commercial build next.
