What Is a Contractor Register?

Quick answer: A contractor register is a central record of every contractor and subcontractor your business engages, including their company details, ABN, insurance certificates, licences, WHS documents, induction status, and approval to work. It is the foundation of your contractor management system and your primary evidence of due diligence if something goes wrong.

If your business engages contractors or subcontractors — even occasionally — you need a system for tracking who they are, whether their insurances and licences are current, and whether they have provided the WHS documents required before work starts. A contractor register is that system.

This guide explains what a contractor register is, what it should contain, why it matters, and how to keep it up to date.

What is a contractor register?

A contractor register is a structured document — typically a spreadsheet or table — that captures key information about every contractor and subcontractor your business engages. It gives you a single, searchable record you can refer to when approving new engagements, verifying compliance before a project starts, responding to audits, or investigating an incident.

The register covers the contractor's identity, their qualifications and credentials, the documents you have received from them, and their current approval status on your sites or projects.

Think of it as your contractor's "file" — compressed into a single row per contractor so you can see everything at a glance.

What does a contractor register record?

A well-designed contractor register will capture the following information for each contractor or subcontractor:

Identity and business details

• Contractor / subcontractor name — trading name and legal entity name if different
• ABN — Australian Business Number, used to verify the business is registered
• Primary contact — name, phone number, and email address
• Work type / trade — the category of work they perform (e.g., electrical, labour hire, cleaning, plant operation)

Description of work performed

• Scope of work — a brief description of the specific tasks or services they carry out for your business
• Site(s) or project(s) — where the work is performed
• Engagement dates — when the current engagement commenced and the expected end date

Insurance details

• Public liability insurance — insurer, policy number, coverage amount (minimum commonly specified in contracts), and expiry date
• Workers compensation insurance — insurer, policy number, and expiry date (required if the contractor has their own workers)
• Professional indemnity insurance — where relevant to the scope of work
• Other insurances — for example, plant and equipment insurance, where applicable

Recording expiry dates is essential — an expired policy provides no coverage, and the expiry date is the first thing an insurer or regulator will check after an incident.

Licences and registrations

• Relevant licences — for example, electrical contractor licence, builder's licence, scaffolding licence, asbestos removal licence
• Licence number — so it can be verified with the issuing authority
• Licence expiry date — to trigger a renewal reminder before work recommences
• Individual worker licences — where the work type requires individual workers to hold their own licence (e.g., dogman, rigger, boilermaker)

WHS documents received

• SWMS received — whether a Safe Work Method Statement has been provided for any high-risk construction work, and the date received
• JSA / SOP received — for non-construction work, whether a Job Safety Analysis or Safe Operating Procedure has been provided
• WHS Management Plan — for principal contractors managing large construction projects
• Emergency procedures — whether site-specific emergency information has been acknowledged
• Other WHS documents — any additional documents required by your site rules or contract, such as plant pre-start checklists or chemical registers

Induction and approval

• Site induction completed — yes/no, and the date completed
• Induction type — whether the induction was a full site induction, a project-specific briefing, or an online induction
• Inducted by — the name of the person who conducted the induction
• Approval status — whether the contractor is approved to work, conditionally approved (pending a document), suspended, or no longer engaged
• Approved by — the name and role of the person who granted approval
• Date approved — when approval was granted

Why does a contractor register matter?

Contractor WHS management

Under the Model Work Health and Safety Act, a Person Conducting a Business or Undertaking (PCBU) must ensure, so far as is reasonably practicable, the health and safety of workers — and that definition includes contractors and their workers while they are at your workplace. You cannot manage what you have not documented. A contractor register ensures you have a consistent, repeatable process for verifying that contractors meet your WHS requirements before they start work.

Due diligence

If a contractor is injured on your site, or causes injury to someone else, the question your insurer and any investigating regulator will ask is: "What steps did you take to verify this contractor was competent, insured, and working safely?" A contractor register that records the documents you received, when you received them, and who approved the engagement is direct evidence of due diligence. Without it, you are relying on memory and informal records — neither of which will protect you in a claim or prosecution.

Site control

A contractor register also functions as a site management tool. It tells you who is currently approved to work, whose insurance is expiring next month, and which contractors have not yet completed induction. It prevents the common problem of a contractor starting work before their documents have been checked.

Who needs a contractor register?

Any business that engages contractors or subcontractors will benefit from a contractor register. It is particularly important for:

• Principal contractors on construction projects, who have specific duties under WHS legislation to manage all contractors on site
• Facilities managers who engage multiple trades for ongoing maintenance and repairs
• Medium to large businesses with a regular roster of external service providers
• Businesses subject to third-party WHS audits, insurance reviews, or tender pre-qualification
• Any PCBU where contractor work involves high-risk activities — working at heights, confined spaces, energised electrical work, asbestos, heavy plant, or similar

Sole traders with no workers and no contractors have no need for this register. But if you are a sole trader who is engaged by a principal contractor, expect to appear in their contractor register.

How to maintain a contractor register

Set it up before work starts

Establish your register before engaging any new contractor, not after. Define the minimum documents you require — typically a completed contractor information form, a current certificate of currency for public liability insurance, evidence of any required licences, and a SWMS or other WHS document relevant to the work.

Make approval conditional on completion

Do not allow a contractor to start work until their entry in the register is complete and an authorised person has recorded their approval. This is the step that most businesses skip, and it is the step that causes problems later.

Track expiry dates actively

Add expiry dates for insurances and licences to your register, and review the register monthly — or set calendar alerts — for items expiring within 30 to 60 days. When an insurance policy or licence lapses, update the approval status immediately and notify the contractor.

Review before each new engagement

Even for contractors you use regularly, re-check their details before each new project or engagement period. Businesses change: they let insurance lapse, allow licences to expire, or change the scope of their work. A contractor who was compliant six months ago may not be today.

Keep copies of documents

The register should cross-reference where the actual documents are stored — whether in a shared drive, a document management system, or your WHS software. Noting "received" in the register is not enough if you cannot produce the document when asked.

These are illustrative examples only. Your register format should reflect the requirements of your business, industry, and any applicable contracts.

How the contractor register fits into your WHS system

The contractor register does not work in isolation. It should be connected to:

• Your contractor onboarding process — the steps a new contractor must complete before being added to the register and approved
• Your site access controls — so that only approved contractors can enter the workplace or project site
• Your incident investigation process — so that contractor involvement in any incident can be quickly cross-referenced against their approval and document status
• Your document management system — where the actual certificates, licences and SWMS are stored
• Your management review — where contractor performance, incidents and compliance trends are reported to senior management

A contractor register that is reviewed only when something goes wrong is not a WHS management tool — it is a paper defence. When it is integrated into your onboarding, site access and review processes, it becomes a genuine system for managing contractor risk.

Frequently asked questions

Is a contractor register a legal requirement in Australia?

There is no WHS regulation that uses the exact term "contractor register," but PCBUs have a duty under the Model WHS Act to manage the risks associated with contractors and to consult, cooperate and coordinate with other duty holders. A contractor register is the most practical way to demonstrate you have done this. It provides documented evidence that you verified insurances, licences and WHS documents before work commenced — which is exactly what a regulator or insurer will want to see following an incident.

What is the difference between a contractor register and a contractor induction record?

A contractor induction record captures who attended an induction, what was covered, and when it was completed. A contractor register is broader — it is the master record for each contractor, including their company details, ABN, insurances, licences, WHS documents, induction status, and approval to work. The induction record feeds into the contractor register as one line item.

How often should a contractor register be updated?

At a minimum, review your contractor register before each new engagement and whenever a contractor's details change. For ongoing contractors, set a calendar reminder to check insurance and licence expiry dates at least 30 days before they fall due. Annual reviews of the full register are good practice, and the register should be updated immediately whenever a contractor's status changes.

Do we need a contractor register for one-off trades like plumbers or electricians?

Yes — even for one-off engagements, you should record basic details including the contractor's name, ABN, licence number, evidence of public liability insurance, and any relevant WHS documents. A brief entry in your contractor register is all that is required. The effort is small, but it protects your business if something goes wrong during or after the work.
