WHS Audit Cost Calculator
Estimate the cost of a WHS (workplace safety) audit. The scope and the size of your business are the main cost drivers, along with how the provider charges.
Your whs audit details
Your estimate sits within the typical range.
A basic WHS review is affordable and finds the obvious gaps; a full ISO 45001 certification audit is a much bigger, formal process. Scope the audit to what you actually need, compliance review vs certification, before quoting.
💰 Ways to save
- Get a few quotes and compare on scope and inclusions, not just the headline price, cheap quotes often leave things out.
- A fixed-scope package is easier to budget than open-ended hourly work, ask whether one is available.
- Bundle related services with one provider where you can, it often earns a better overall rate.
