Information for businesses about how to report suspicious behaviour.
We rely on complaints to help us promote healthy competition and protect the interests of consumers and fair-dealing businesses. If you suspect a competitor, supplier, customer or any other business is infringing the law, please contact us with your concerns.
There are a number of signs that may mean a business you deal with could be breaking competition law. These include:
If a business appears to be behaving in any of these ways, it does not necessarily mean it has breached the law. In some cases the behaviour may be a legitimate response to strong competition.
Please contact us before making a formal complaint. We can advise you on whether the matter is likely to raise competition issues and explain how to submit a complaint.
