I find this company truly remarkable

I find this company truly remarkable. My journey to 100Green began after my previous supplier increased my rates by 17%. When I tested the market, that supplier contacted me three separate times, eventually offering a rate even lower than my original price. I fundamentally disagree with that policy; as a loyal customer of four years, I should be offered the best price initially, not as a desperate attempt to prevent me from leaving.
Out of all the providers I considered, 100Green stood out. While their pricing wasn't the absolute lowest, it remained competitive and unusually, there was no financial penalty should I wish to leave my contract early. Crucially, their reviews suggested they were easily reachable by phone - a claim I have since verified to be entirely true.
Once I changed I reconsidered my attitude to smart meters. Because my apartment is roughly 70 yards from the meter cupboard, a normal In-Home Display (IHD) wouldn't function. However, because 100Green is so approachable, I agreed to the switch on one condition that they provide a working IHD using an ALT HAN (Alternative Home Network) system. I understand that in practice only a few suppliers will do so. 100Green agreed, and although the installation took longer than anticipated, it has been working perfectly for several weeks.
Throughout this process, I needed to call them several times. Each time, I was met with a polite, welcoming and knowledgeable person - not an ineffective chatbot, a "see website" brush-off, or even to consult a FAQ list on their website. In this digital age, such service is a rarity. I have no personal relationship with 100Green other than being a satisfied customer and it is a genuine pleasure to recommend them so highly.

Hi David,

Thank you for the amazing review — we really appreciate your feedback! I’m glad that you’ve enjoyed speaking with our team. We firmly believe that a real, knowledgeable person will always be better than a chatbot. It’s also great to hear that your ALT HAN installation is working perfectly. We’re proud to do things differently here at 100Green.

If you ever need anything, don’t forget, we’re only at the other end of the phone.

Have a wonderful weekend!

Best regards, Lewis

Exceptional service from Billie Harding!

I had an amazing experience with 100Green today. Billie Harding was incredibly helpful, efficient, and professional. She assisted us in updating our account names for a residency proof application and handled everything smoothly. Her communication was top-notch, and she went above and beyond to ensure the document was perfect. Thank you, Billie, for the 5-star service!

Real Person.

Firstly 100 Green you get to talk to a real person straight away, no horrible menu to work through. Secondly I recognised the friendly voice which was even nicer, almost remembered her name and she remembered talking to me in past. Thirdly she sorted my issue really quickly and efficiently. Certainly deserves 5 star rating!

Glad I Changed Suppliers.

For a period of time I had some bad experiences with fuel suppliers. After speaking to 100 Green and my contact ,a lady named Billie, I decided to change to them as my supplier. I have been so impressed with Customer Care and spoke with Billie about my specific needs , as i have health issues . She patiently listened and since then has gone over and above to ensure that,as there client, ime happy with there service. Ime glad i changed and would like to say Thank You to Billie for her kindness and professionilism, extremely grateful.
