Making a complaint

We’ll do our best to give you efficient and friendly service, but we might not always get it right. Please let us know if you have a problem or a complaint and we’ll work hard to put things right. Here’s how we deal with complaints:

Step one

Contact us using any of the following methods:

By phone

0800 954 0693

or 01926 516152

Mon – Fri      08:00 – 20:00

Sat  -            09:00 – 16:00

By post or in person

Co-operative Energy

We’ll try to put things right straight away, but please allow us up to five working days to make all the necessary enquiries.

Step two

If you are still not happy, we will escalate to our Customer Service Manager for an independent review. We’ll let you know the outcome of that independent review within ten working days.

Step three

If you are still not satisfied that your complaint has been resolved satisfactorily, it will be escalated to our Customer Relations Department, who will examine the case objectively and give you our final response.

Step four

In the unlikely event that our handling of a complaint leaves you still feeling dissatisfied, or where we have been unable to resolve things within eight weeks, you have the right to contact the Energy Ombudsman as follows:

Tel: 0330 440 1624 or 01925 530 263

Energy Ombudsman, PO Box 966, Warrington WA4 9DF

The Energy Ombudsman provides a free, independent service and will investigate our handling of your complaint. Any decisions made by the Ombudsman will be binding on Co-operative Energy.
