Investigations

This section of the site contains information about the investigations of the Competition Commission, including details of what we investigate and how we conduct inquiries & energy code modification appeals.

There is also information about individual inquiries and appeal cases. You can search our listings of inquiries since 2000 in a variety of ways:

• by company
• by subject (e.g. supermarkets, airports, railways)
• by date of completion (organised by year)
• or by reference type (merger, market or other reference type)

There is also a complete set of inquiry reports back to 1950 organised by date and details of Energy Code Modification Appeal cases.
