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:

• a supplier prevents you from selling their products at a discount
• a long-standing supplier decides, for no apparent reason, to stop supplying you
• you receive quotes from various suppliers that are surprisingly and unusually similar
• you enter a market and a major competitor responds by charging extremely low prices that you suspect would not cover its costs.

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.
