Positive GB Energy Reviews

Carol Ainsworth on Trustpilot:

Over the last few months, l have spoken to some people, including a manager. Everyone has been very helpful, knowledgeable and a joy to deal with. I’ve only dealt with them to close my account, as l had found a cheaper supplier. Unfortunately, my cheaper suppliers do not have the excellent customer service skills of GB Energy part of Co-Operative Ltd, Warwick Technology Park.

Negative GB Energy Reviews

David Irving on Trustpilot:

As other people on this site have stated, IF I COULD GIVE THEM ZERO STARS I WOULD! I am a landlord & my previous tenant choose this company. They over charged me dramatically for the period between tenants. Demanding things like tenancy agreement copies with dated etc. and ten ignoring my once I provided them. They would not speak to me saying it was in the hands of their debt collector. The debt collector was more understanding and accommodating than GB energy.

Martyn Blackford on Trustpilot:

Deducted another £44 from my account the day after it’s been closed. You also have to ask them for any refunds on accounts in credit. Avoid them!
