This guide summarises how the CMA gathers information when it suspects that a business might have broken consumer law. We can use our powers at any time: before or after we decide to open a case, or without us having to open a case at all.
This is for people who:
- own, manage or work for a business which is currently being investigated by the CMA, or might be in the future
- have been asked by the CMA to provide information about a business that is, or may be, investigated (for example, you might be a business’ supplier)
If we suspect that you might have broken the law, we may open a case.
This guide is a summary of the main points of chapter 7 (Powers of investigation) of our consumer enforcement guidance (CMA58). Read the full guidance for more information.
