Customer Support

Positive Customer Support Review

Cathryn Brooks on Trustpilot:

The process was very easy and I have received good customer support.

Negative Customer Support Review

Aden Fawcett on Trustpilot:

I agree with the other people who are complaining the services are a sham the customer service is diabolical. After stating that I would be moving accounts to another supplier, I was informed that I could not move as we owed money even though we pay by DD and they had not sent an estimated or actual bill.

Green Star Energy Reviews

Green Star Energy has an average 3-star rating on Trustpilot, with 44% positive reviews, 32% negative and the rest in the middle.

They have been praised for the ease that customers experienced switching providers to them, however, once customers have wanted to switch away, they have been running into problems.

Although online reviews aren’t always accurate, you should still consider them when deciding which supplier you want to switch to.

Positive Green Star Energy Review

Diane on Trustpilot:

Very easy switch over. No supply interruptions. Courteous and helpful staff when I rang about having two accounts set-up.

Negative Green Star Energy Review

Rob Nixon on Trustpilot:

We have also left GreenStar Energy and why they say it may take up to 6 weeks to do it, is because the moment you say you are leaving they put you on their premium Tariff which is their highest charging rate. It’s to squeeze every last penny out of you before you leave them.
