Our Complaints Procedure

Any problems with our service

At ENGIE we pride ourselves on providing an exceptional service to all our customers. However, we know that there will be times when we get things wrong. When this happens, we promise to take this seriously and aim to sort things out as quickly as possible.

If you’re unhappy with our service, for whatever reason, then we’d like to understand why, so we can endeavour to put things right as quickly and effectively as possible.

Our complaints process is outlined below:

Making a Complaint

Contact our Customer Service team

- Call us free on 0800 280 8000

- Email us at complaints.uk@engie.com 

- Write to us at ENGIE Home Energy, PO Box 330, Newcastle, NE12 2FP

If at any time you would prefer to talk to us face to face about your complaints, you can visit one of our Customer Service Offices. Please contact us for details of your nearest office.


Resolving your complaint

Our Customer Service team are all fully trained to handle any expression of dissatisfaction and complex cases.

We aim to resolve your complaint at the time of the first contact where appropriate and possible. If we cannot resolve your complaint at the first contact, we will issue you with a complaint reference number, as well as acknowledging your complaint in writing.

Whilst your complaint is open, we will endeavour to keep you informed at agreed times to ensure you are kept upto date as to the progress of your complaint.

If you feel that your complaint has not been handled to your satisfaction, you may ask to speak with a Team Leader.

Rest assured we will work hard to resolve your complaint as quickly as possible. However, if after 8 weeks a resolution hasn’t been reached to your satisfaction, you have the right to contact the Ombudsman Service; Energy.

If we can’t reach an agreement with you, we will send you a “final offer” letter (known as “deadlock”). You can then seek independent advice from the Ombudsman Service; Energy. If you do decide to do this, you must contact them within 12 months of receiving our letter. You can also contact the Ombudsman Services, if you have not received our letter, but 8 weeks have passed since you first complained.

Ombudsman details

The Ombudsman is there to help resolve disputes between energy suppliers and their customers. It is free to use and they are totally independent, so they don’t take sides and make their decisions based only on the information available. You do not have to accept their decision. If you agree with their decision, we have to act on what they say. This may mean we have to apologise, explain what has gone wrong, correct the problem or where applicable offer a form of compensation or goodwill.
