Report competition law infringements

Your answers to the questions in this form will help us decide if we should formally investigate your complaint under the Competition Act 1998. 

You do not have to answer all of the questions but we recommend providing as much information and supporting evidence – for example, copies of meeting notes, emails, letters and/or invoices - as you can. The more specific and concrete the information you are able to provide, the better we are able to review a complaint and reach a decision on next steps efficiently. 

Please let us know if you have contacted any other regulators or organisations with your complaint.

All information we receive will be handled in accordance with the Data Protection Act 2018, the UK General Data Protection Regulation 2021 and other legislation designed to protect individual privacy and commercial confidentiality. Contact us by email at c[email protected] if you have any questions or concerns.

You can also submit your report by email to [email protected] or by post to: Competition Division, Financial Conduct Authority, 12 Endeavour Square, London E20 1JN.
