Excellent customer care staff response speed and quality

Update: I had to dock 1 star because the information provided was not entirely correct leading to my incorrect hypothesis about the address lookup.
Apparently, almost all energy providers and comparison sites use the "meter profile class" to decide if a property is domestic or business. Except Uswitch and outfox who use the "Domestic Premises Indicator" to decide if a property is domestic or business. Fixing the Indicator resolved the issue.

Extremely fast and excellent customer service even on a Sunday. Speedy and concise answer to my question. Thanks Camille.
The problem was caused by apparently faulty address lookup systems at Outfox and Uswitch.
Those organisations will be receiving 1 star reviews.

I had amazing customer service/care from a really helpful, kind and informative lady called Carina. She went above and beyond to rectify a discrepancy with my bill and to get me set up correctly.
Thankyou Carina, you deserve and should get a payrise.

NoAbsolutely brilliant company who treat you like a person not a number , this company has put themselves out over an above what you'd expect all the staff are friendly and always there to help , highly highly recommended.10/10 I for one thank 100green for getting me out of energy trouble an setting me back on the right track without any stress, thankyou everyone at 100green , give yourselves a big pat on the back once again thankyou .

Have just moved over to this energy provider but had a dispute with the final bill from my previous supplier due to incorrect final meter readings. Anita was very helpful in getting this resolved and keeping me informed with what was going on.

great to speak to members of staff who help no matter what the issue is. very quick at answering calls and emails. excellent service overall, would recommend to anyone.

Karina. Who I sensed from the way we spoke on the phone understood my situation.

I spoke with Linda and she was SO helpful and extremely kind under very stressful circumstances. A true professional! And asset to 100green, I have just moved into a new flat and look forward to dealing with them!!!

Hi, great company and lovely people. It's nice to talk to the same agent each time rather than someone in a call centre. When ever I've had a query, it's been dealt with quickly and efficiently. It's nice to be a Green with so little effort!

Linda was really helpful and super friendly. Great customer service

Always quick to pick up phone and very helpful and friendly

We had a very long (7 months) and problematic switch-over to a Smart Meter. On the plus side, 100Green were really easy to contact and speak to direct throughout; and they kept an amazingly close watch on everything that was going wrong. The personal touch was really appreciated. On the minus side, everyone seemed to be on a wild goose chase -- led by SMS metering -- and strangely misinformed about the compatibility of various meters with the Economy 10 set-up which surely many storage-heater users still rely on. There was a lot of false internal communication going on behind the scenes. But it all came right in the end (I think, so far...). 5 stars to 100Green team members; 1 star to SMS (despite their friendly and helpful individual engineers) and the whole push to roll out smart meters prematurely.

Very helpful with my BIll, Lisa has been amazing she explained to me in a way I have understood and made my life much easier

Carina Jones was excellent in supporting my query today. It's rare to get customer service of this quality. First, I was put through to someone almost immediately, without the usual being put on hold and/or automated options. Carina was informed, helpful and clear. We communicated by phone and then by email as a document needed to be sent. She then followed up promptly with a phone call to complete the request. It was all seamless and fast. I couldn't ask for a better service. Thank you.

Immediate and efficient response to an email query about our account. Customer service is excellent as is the company's ethical and environmental standards.

I cannot fault the Customer Service Dept. who dealt with my query professionally and promptly. Special thanks to Inma Azunma.

I rang them up, a nice lady answered the phone (Sarah). My query was dealt with in seconds without asking me my second hamster's middle name, without endless keypad options that didn't apply, without a lengthy explanation that Covid (it is 2026) has affected the service. Marvellous. Exactly how phoning a company should be.

Excellent customer service, I have already recommended this company in the past and will continue to do so.

100Green is a terrible company. We have been with them for less than a year and are already changing providers. The issues we have had in the last few months is beyond ridiculous. As stated we are changing providers and this is due to the fact we have told them we have solar panels but every time we get a bill there never seems to be anything indicating that we are getting money back/saved from the solar panels. I must have told them this 3/4 times in the space of less than a year and still having issues. We were told that the company themselves will take meter readings and if there is any issues they would let us know and we can provide a meter reading. On 3 different occasions (including the most recent bill) our bill has doubled from what it usually sits at, when I’ve phoned and asked we are usually told that this is due to a faulty connection in our house and it’s caused wrong meter readings. If they knew we had a faulty connection, why haven’t they told us. We were told someone would be in touch to try and solve this connection issues but shocker, no one has ever been in touch. With our most recent bill and the fact we are changing providers, our bill has doubled and it’s again due to a faulty connection. The reason we chose 100Green in the first place was due to competitive pricing but since we have had a “faulty” connection this really hasn’t worked out that way. Having looked at our bill, they are trying to say we have used in 3 days what we would usually use in 2-3 weeks. I also remember when we first began with 100Green our energy bill was almost 4x what it was said to be and when I called up, I was told that was just the way it was. However, I got in touch with the providers before 100Green and we found out they had used meter readings months before we had made the change. This diff result in us getting our money back but too many times has this company been so dodgy.

Service team are great and really helpful but the company feels chaotic. As with others we had a rocky start. They ported over our neighbours meters to our account despite her refusing the first request and ignoring the second. It took 2 months to sort out.
Then there's the (completely useless) new mobile app which doesn't seem to work on either Android or iPhone. No data shows up and it's not possible to click into anything to get info or log meter readings. It's been like that for 3 months. Not confidence building.
