Energy Code Modification Appeals

This page provides links to the main statutory provisions of the Energy Act and other essential texts including the Competition Commission’s Rules and Guidance, and a short introduction to this new responsibility of the Competition Commission (CC).

If you wish to request permission to bring an appeal you should contact the CC’s Inquiry Support Unit on telephone number 020 7271 0115 to obtain a reference number for the appeal and contact details for the Appeal Secretary. If ringing out of hours, leave a message which will be dealt with on the next working day.

All parties to appeals should consult the CC’s Rules and Guidance and make use of the appropriate templates—see the links on this page—when preparing their cases.
