HOW TO MAKE A COMPLAINT

Step 1

Please do talk to us. If we don’t know it’s broken, then we can’t fix it.

We will look into the matter and get back to you within 5 working days.

Please note that some account related issues can take time to fix – so until we’ve found a solution, we recommend you keep making regular payments to cover your energy usage.

Call us on 0808 175 4975

Email: complaints@100green.com

Step 2

If, after our response, you are not satisfied with the outcome then please formally write to the Directors.

Email: complaints@100green.com
(For the attention of the Directors)

Post:

Step 3

In the unlikely event that we reach ‘deadlock’ and our directors cannot find a solution that you are happy with, or it’s taken us longer than eight weeks to resolve, you can contact the Energy Ombudsman.

It’s always worth a conversation

We work on a philosophy of ‘prevention rather than cure’. Most of the issues raised with us are regarding customer’s bills, which we ﬁnd can usually be resolved easily with a conversation. But we don’t just wait for customers to come to us; we regularly carry out what we call ‘health checks’ on customers’ accounts to ensure they don’t build up credit or debit balances.

Our Customer Promise document sets out the full standards you can expect from us.

COMPLAINTS REPORTING

We are accountable

We are proud to say that we still provide a phone-first service, meaning when you call, one of our team will answer, helping to ensure any issues are dealt with swiftly.

But, of course, there are always a handful of problems that are escalated.

OFGEM deﬁne a complaint as an ‘expression of dissatisfaction’.

Against industry standards, we’re pleased to say our complaints history is very low.
