GDF SUEZ Mediation comes as a complementary resort to the complaints handling processes implemented by the different Group’s customer services, and thus offers claimants a last resort for out-of-court settlement within the GDF SUEZ Group, in situations where claimants are dissatisfied with the response given to their complaints.

Michel Astruc was appointed Mediator by the Group’s Chairman & CEO in November 2005. His professional career explains his strong experience in the businesses of energy and relations with stakeholders. He is completely independent. Every year, he produces a report describing his activities, a summary of requests received, an analysis of the cases handled and details of recommendations made to operational services.

 How to seek the assistance of the Mediator

The Mediator can only be contacted when the GDF SUEZ customer services have already been requested and the solution put forward was unsatisfactory.

The Mediator can be contacted in writing:

  • by ordinary letter, addressed to:
    Médiateur GDF SUEZ – TSA 34321 – 92099 LA DEFENSE Cedex – FRANCE
  • by completing the online form.

How will your request be processed?

All requests are examined and followed up. Depending on your initial complaint,

  • either it is sent to the concerned services for processing and monitored until resolution, when prior procedures have not been followed through.
  • or, as a last attempt to settle at an out-of-court settlement within GDF SUEZ, it is handled by the GDF SUEZ Mediator, who will contact you to get all the details and work out a fair and legal solution with you and the service concerned.

The 2013 report from GDF SUEZ Mediator Michel Astruc has recently been published

The GDF SUEZ Mediator is pleased to announce the publication of his annual report for 2013. This document reminds the context of GDF SUEZ Mediation and summarizes its actions, analyses, and recommendations.

A key development in 2013 was the adoption of the Alternative Dispute Resolution (ADR) directive and of the Online Dispute Resolution (ODR) regulation, which ensures to every consumer access to an officially-approved body providing amicable dispute resolution, on any issue, throughout the European Union territory.

 Encouraged by a 92% case-resolution success rate, GDF SUEZ Mediation promoted, again this year, amicable dispute resolution as a credible alternative to legal action in many cases, and this across all Group’s departments. Michel Astruc works to spread mediation in many other areas as well.

 There were several interventions made in law universities and business schools. These events reflect the growing interest in mediation in many professions and are an effective vector for educating future graduates about amicable dispute resolution and the challenges of a quality mediation.

In a difficult and sustainable economic context, GDF SUEZ Mediation takes part in discussions and initiatives on the topic of vulnerable consumers, and contributes to the efforts made by The Observatory of Fuel and Water Poverty of GDF SUEZ.

 The Mediator recommends better understanding of the fundamentals of complaints handling and to simplify the customer experience to better meet consumer’s expectations, using available best practices established by various mediators.

 The year 2013 was also the opportunity to promote mediation at the “Mediation : la confiance d’abord” symposium at the Economic, Social & Environmental Council, organised by The Club of the Mediators of Services to the Public. Jean Paul Delevoye called upon mediators to take dialogue further and participate actively in necessary developments regarding institutions’ and companies’ way of operate.

 Furthermore, the GDF SUEZ Mediator is in charge of representing the EEOG (European Energy Ombudsmen Group) in Brussels. This year, this European association of mediators from companies in the energy sector continues its work on the “Zero Unsatisfied Customers” project, ensuring the complete satisfaction on the part of all customers having requested mediation.
