What we’ll do...
A full independent review of your complaint will be carried out by our specialist Complaint Investigation Team. All correspondence and actions taken to date will be investigated, with the hope that your complaint can be resolved. Again, we’ll work hard to review and resolve your complaint in 10 working days and will keep you up to date on progress if it is taking longer than this. In the instances where it is not possible to agree an appropriate resolution, we will provide you with a letter that states our final position. This is sometimes referred to as a Deadlock letter. If you are not satisfied with our final offer and position, you may continue to pursue your complaint through other third part channels, such as consumer groups or arbitrators.

Complaints outcome

We will respond to your complaint within 10 working days. Following full review of your complaint we may take the following actions:

  • Apologise and explain to you our findings and why this has occurred
  • Take appropriate action to put things right
  • Explain our next steps which may include compensation, paid by EDF Energy in appropriate circumstances, for example, if your complaint relates to our sales activities (once the full investigation is complete)
