Subcontractor Prequalification in NSW — Everything You Need to Know

What documents you need, which systems builders use, how much it costs, and how to stay prequalified without losing a full day every renewal cycle.

What is prequalification?

Prequalification is the process by which a principal contractor verifies that a subcontractor has the safety systems, insurance, training, and documentation to work safely on their sites. It is not a legal requirement under the WHS Act — no provision of the WHS Act 2011 or WHS Regulation 2025 mandates prequalification. It is a commercial requirement that has become an industry standard, driven by principal contractors' own PCBU duties under s.19 and s.20 of the Act. A principal contractor who allows an unqualified, uninsured, or untrained subcontractor onto their site faces prosecution if that subcontractor's worker is injured. Prequalification is how principal contractors manage this liability.

What documents do you need?

The specific requirements vary by principal contractor and prequalification system, but the common requirements across all systems are consistent. Current public liability insurance is universally required, with minimum cover typically ranging from $10 million to $20 million depending on the project value and risk. Workers' compensation insurance is required if you employ anyone — this is mandatory under NSW workers' compensation legislation, not just a prequalification requirement. Relevant trade licences (electrical, plumbing, gas fitting, demolition, asbestos removal) must be current and held by the person performing the work, not just the business. A SafeWork NSW general construction induction card (White Card) is required for every worker who enters a construction site, and the holder must have carried out construction work within the preceding two years for the card to remain valid. Safe Work Method Statements are required for every high-risk construction work activity you perform, as defined in WHS Regulation 2025 s.291. A safety management plan or safety policy demonstrates your approach to managing WHS across your business. Training records for all workers must show completion dates, competencies achieved, and expiry dates where applicable. An incident register demonstrating your safety history — even if the history is zero incidents — provides evidence of proactive safety management.

Which prequalification systems do builders use?

The main prequalification platforms used by principal contractors in NSW are Cm3, Avetta (formerly Browz/PICS), and Veriforce. Some builders also use their own internal prequalification questionnaires or portals. Each system asks for similar documents but in different formats and with different upload requirements. If you work for multiple builders using different prequalification platforms, you may need to maintain active subscriptions on multiple systems — each with its own annual fee. This is one of the most common frustrations subcontractors report: paying multiple platforms for what is essentially the same compliance verification.

How much does prequalification cost?

Cm3 fees range from approximately $600 to $2,000 per year depending on your risk tier, number of principal contractor connections, and the level of assessment required. Avetta charges similar fees on a comparable tier structure. These are annual subscriptions — if you stop paying, you lose your prequalification status and your access to those builders' sites. Some principal contractors also charge their own assessment fees on top of the platform subscription. For a sole trader earning $80,000-$120,000 per year, the combined cost of multiple prequalification subscriptions can represent 2-4% of gross revenue.

How EHS Atlas makes prequalification easier

EHS Atlas does not replace Cm3 or Avetta — those are the platforms the principal contractor chooses and the subcontractor must use. EHS Atlas is the management system that keeps all your compliance documents current, organised, and export-ready so that when any prequalification platform asks for a document, you can produce it immediately. When Cm3 asks for your insurance certificate, you download the current version from EHS Atlas. When Avetta asks for your SWMS, you export it. When any system asks for your training matrix, it is already generated. The annual prequalification renewal that used to take a full day of document hunting takes 30 minutes because every document is in one place, current, and ready to export.
