Case information

The investigation concerns suspected infringements of Chapter I of the Competition Act 1998 (CA98).

This case is at an early stage and no assumption should be made that the CA98 has been infringed. The CMA has not reached a view as to whether there is sufficient evidence of an infringement of competition law for it to issue a statement of objections to any of the parties under investigation. Not all cases result in the CMA issuing a statement of objections.

If the CMA issues a statement of objections, it will provide the addressees of that statement of objections with an opportunity to make written and oral representations. Find more information in the CMA’s Procedures in Competition Act cases.

Personal data

The CMA may collect, use and share personal data for its investigations, including investigations under the Competition Act 1998. This includes processing personal data for the purposes of the General Data Protection Regulation and the Data Protection Act 2018.
