In comparison to past experiences with another company, I can't say enough what a great service 100green offers. The phone staff is a joy to talk to. They are helpful and I don't dread ringing. Brilliant! My thanks to the staff and I am planning to stay with 100Green!!

Exemplary customer service

I called up 100Green today as I wanted to discuss leaving. I spoke to the lovely Karen who was incredibly helpful, going above and beyond, and reassuring me, despite the fact I am leaving.

I'm sorry to leave behind wonderful customer service, based on a better price I have found elsewhere.

Thanks for being so helpful, Karen.

Absolutely awful experience with…

Absolutely awful experience with 100Green.

I requested a quote and provided my bank details to set up a Direct Debit mandate. After everything had been arranged, I was suddenly told that I would need to pay a £500 deposit due to my credit score. I immediately told them I did not want to proceed and did not want to become a customer.

I then used their live website chat and confirmed TWICE with an agent that my application had been cancelled and that the Direct Debit mandate had been removed. Despite this, 100Green went ahead and transferred my gas and electricity supply to them without my knowledge or consent.

When I called to complain, I asked them to find the live chat transcript that clearly showed I had cancelled. Amazingly, they claimed they could not locate it. How can a company lose records of customer conversations, especially when those conversations contain instructions to cancel a service?

To make matters worse, the customer service was terrible. The representative I spoke to was rude, dismissive and completely unhelpful. Instead of resolving the issue, I was left feeling ignored and frustrated.

The entire experience has been stressful and unacceptable. A company should not transfer someone’s energy supply after they have clearly cancelled, and then be unable to find the evidence of that cancellation. I would strongly advise others to think carefully before signing up.

Hi Bianca - I am sorry to hear about this experience. We would never ask for a deposit of £500 on sign up and I'm afraid I am unable to find your account in our system. Would please respond to the request for more information which will come via Trustpilot? We can then locate your details and take a look at what has happened. Thank you so much. Amy

Great service from knowledgeable staff

I have received nothing but great service from 100Green. They answer quickly to calls and emails and are extremely knowledgeable and action things quickly. My most recent experience was with Billie via email where she actioned my request within 2 hours of me emailing. Very happy with the service!

Linda's customer service was Outstanding

Linda's customer service was outstanding. She was understanding and able to create a solution to the issue I was having. She explained everything she was doing so I was able to understand the process and also had great aura about her. Being able to build normal talk into the conversation whilst not forgetting the task at hand is a great quality. Amazing service. Thank you Linda, after having a rubbish morning, you have really made my day!

Being harrassed by this company over a debit in my fathers name who has been dead for 4 years basically someone has fraudulently using his details. Reported matter to the police and we are being called liars absolutely disgusting way to treat a family who are still grieving for a loved one who has passed away!

Poor app and poor website!! 1star

100 Green you need to sort your app and website for reading it is so poor and monthly view is shocking specially if you have solar panels and batteries can’t see what you use! I have moved due to this as no good for monitoring things! Only good thing about 100 green is low over night rates! Also to add no email to say you have switched I had email in! To ask
