Great service

Great service given by 100Green. Always pick up the phones and incredibly caring and attentive - Joe took the time to explain the issue I had in lots of detail in email and even called me when I wanted more detail. 10/10

Excellent Customer Service

Really helpful, friendly, knowledgeable advisors who answer the phone almost immediately.; no queuing, no struggling to be understood. My questions & concerns were answered fully, with empathy & total understanding. Possibly the best customer service experience I've EVER had with an energy company!!

Spot on customer service.

Spot on customer service.
I’ve been with 100 Green after switching using the cheap energy switch club ( or what ever it’s called) on the M.S.E. Site. A year ago. This year I went searching for the cheapest deal to find that my home was classed as commercial 🤷🏻‍♀️ and therefore couldn’t get a domestic use quote from anyone. I contact 100 green with my problem, I am pleased to say that I had a prompt response, they had investigated and yes for some reason (after 27 years) had been changed from domestic to commercial on the national database. Within 48 hours the problem had been rectified and I had been informed at all stages within that process. From my point of view, I’ve found the service to be exceptional given my experiences with other companies in recent years. Given my experience- yes I could maybe save £30 a year if I switched but I think that this company deserves to keep me as a customer for the coming year.

Exceptional Support and Compassionate Service from 100Green

I am absolutely delighted with the exceptional service I received from 100Green, particularly from Sharon Warne in the Credit Control team. After a challenging period with a supply and account issue, Sharon handled my case with remarkable professionalism, empathy, and dedication.

She went above and beyond to ensure my situation was resolved fairly and swiftly, keeping me informed every step of the way and treating me with genuine care and respect. The entire 100Green team demonstrated integrity and a true commitment to customer satisfaction.

I’m deeply grateful for their outstanding service — it truly made a difference. I wholeheartedly recommend 100Green as a 5-star company that values and supports its customers.

Polite and efficient customer services

Called customer services - phone answered quickly and query resolved efficiently and politely by “Summer”.

I regularly use the app to monitor my account, it’s user friendly and the link to call customer services worked brilliantly making it all very hassle free.

Good bye and good riddance Eon - hello 100Green!

Used to be with Eon and what a change! Whereas I used to deal with 101 people none of whom could grasp what was going on with our faulty meter now with 100Green I get prompt replies to emails, where they sort the problems out - and even gave a refund without me asking. Unlike Eon, they actually respect the customer!

Excellent Customer Service!

I recently had to manage an awkward 10-day overlap while moving house, and 100 Green were absolutely brilliant in helping me get everything sorted with my electricity supply. I spoke to Lucy, who was incredibly friendly, patient, and efficient. She made what could have been a stressful situation really easy and reassuring, ensuring that everything was covered seamlessly between properties.

It’s rare to come across such genuinely helpful customer service these days! My call is always answered quickly, making the process so smooth! Highly recommend.

Hi Thomas - ah thank you so much for the lovely review. Hope you are finally settling into your new home. Managing bills when moving home isn't at the top of the 'fun things to do' list (!) - so I'm delighted to hear that Lucy was able to assist and make sure everything went smoothly. Have a lovely day.

Best customer service... ever.…

I chose 100 Green because of their eco credentials, and because their price was fair. But the thing that distinguishes them most from other providers is their customer service. It is exemplary. If you have a problem/issue and need to communicate, it is possible to talk to a person who has access to your account history and previous communications and who gets right on and gives one the help needed (no being passed from person to person to repeat over and over your request). It is not just problem-solving at its best, it is breath of fresh air.

Hi Bernadette - what a lovely review! Thank you so much for taking a moment out of your day to let us know. The team are delighted - I think it was Summer who you specifically dealt with so I've let her know how pleased you were. It really does mean a lot when our customers give us feedback. Have a lovely rest of the day. Amy

Great service so far…

We have just moved across to 100Green with great rates. They have fitted a smart meter which their competitors said wouldn't work at our house. When we had a problem - it was easy to speak to a real person and they had an engineer to the house within two hours of my call. Can not recommend them highly enough.

Friendly, Quick & Responsive

My call was answered almost straight away. Once the agent found my account, she was able to dispatch the in-home smart meter & give all the details on the matter.

Customer Service

We were new customers with 100Green and had recently had a solar system installed. When we initially had problems setting up with the correct tariff it was great to have one person as a contact rather than anonymous call centres. Joe was able to liaise between different departments and send feedback directly to us which he did on a regular basis. Well done.

Hi Carol - thank you so much for taking the time to leave a review. Delighted that Joe was able to help you with your tariff. You're right - sometimes things can take a bit of to-ing and fro-ing to get set up so we try to make sure you can speak to the same person each time. I'm so glad the experience was deserving of such a high star rating - I've let Joe know. Thank you again and have a lovely evening. Amy
