iCIRT, the Independent Construction Industry Rating Tool from Equifax, raises trust and transparency in new housing by independently scoring developers and builders from one to five gold stars across 14 criteria, including financial strength, technical capability, defect history and governance. It gives buyers a verifiable, third-party signal of who can deliver, replacing marketing claims with evidence. Billbergia holds a 4.5-Gold Star iCIRT rating (2025).

For a decade, the biggest risk in buying a new apartment was not the apartment, it was the counterparty: would the developer and builder actually deliver, and stand behind the building afterwards. iCIRT was created to answer that question with evidence rather than marketing. This piece explains how the rating works and why it is raising the bar across the industry.
The trust problem iCIRT solves
A wave of high-profile defect cases and a handful of building failures shook buyer confidence in Australian apartments through the late 2010s. The core problem was information asymmetry: buyers had no reliable way to tell a capable, financially sound developer from a fragile one until it was too late. Marketing looked identical across both. iCIRT was created to close that gap with independent, evidence-based ratings.
What iCIRT actually measures
iCIRT, the Independent Construction Industry Rating Tool run by Equifax, assesses developers and builders across 14 criteria grouped around the things that actually predict delivery:
- Financial position and capacity to complete projects
- Technical and construction capability
- Track record and defect history
- Customer complaints and how they are handled
- Governance, conduct and organisational stability
How the star rating works
Assessed entities receive a rating from one to five gold stars, with a trustworthy, capable delivery organisation typically sitting at or above the 3-Gold Star threshold. The assessment is conducted independently by Equifax, is reviewed periodically rather than granted once, and is publicly searchable.
The critical feature of iCIRT is independence. Because Equifax, not the developer, conducts and publishes the rating, it cannot be bought or gamed like a marketing claim. That independence is precisely what makes it a credible trust signal for buyers and lenders alike.
Why it raises the industry bar
iCIRT changes incentives across the whole market. Once buyers, lenders and insurers start preferring rated developers, being unrated or poorly rated becomes a commercial disadvantage. That pressure pushes developers to strengthen financial discipline, defect management and governance to earn and hold a strong rating. The result is a market-wide lift in standards, driven not by regulation alone but by transparent, comparable information.
How buyers should use it
For a buyer, iCIRT turns due diligence from guesswork into a checklist:
- Check whether the developer and builder are iCIRT rated at all
- Confirm the rating sits in the trustworthy band (3-Gold Star and above)
- Treat a strong rating as verification, then still inspect completed work
- Combine the rating with the delivery model and warranty position
iCIRT does not replace inspection and legal advice, but it gives buyers an independent starting filter that did not exist a few years ago.

No. The rating is conducted and published by Equifax, not the developer, which is what makes it credible. Because it is independent and evidence-based, it cannot be bought or gamed like a marketing claim, and it is reviewed periodically so it reflects current capability rather than a one-off assessment.
