Hi Bhupinder,
Great to hear you're having a postive experience with us as your energy provider! Receiving your feedback is also a very postive experience for us. Thank you for your kind words!
With a bright smile,

I have no words. Customer service is simply non existing.
I received an incorrect yearly invoice with over 1000€ extra cost, and 5 weeks later still trying to get a response.
Coolblue did not reply to any of my emails. When I call them, they politely tell me they will address it immediately, but nothing happens… this is not the way I like to be treated as a customer.
Update: 2 weeks later and after replying Coolblue’s request from information, after calling them again…. NOTHING … still no resolution. How long does it take to fix an invoice?

Hi Borja,
Thanks for sharing your experience with us. It’s important to us that your yearly invoice is clear and correct.
I understand you have questions about an extra amount of more than €1,000 on your annual statement. We want to check this properly for you and make sure everything adds up as it should.
We’ve requested your details via Trustpilot so we can look up your contract and review the invoice right away. Together, we’ll find the right solution.
Thanks again for giving us the chance to sort this out for you.
With a smile,
Coolblue Energy
I received a phone call from a Joyce that our contract will end on 9 Nov ,,, I thought this strange as I have just agreed a new contract with Cool Blue for 3 years,,, in this day and age this should not happen,,,makes me very nervous as to their competence

Hi Valerie,
Though we aim to provide a personal service, we don't mean to misinform you!
We take great care in training our service friends to prevent mistakes. However, accidents can happen when it's people working behind the screens. If a human error is made, we are always driven to fix this and improve your experience.
To see if there is anything we can do for you, we have requested your details. Hopefully we can get in contact with each other soon!
With a smile,
Coolblue Energy
They bungled my sign up, can’t fix my app to even show my electricity usage, customer service completely unhelpful, then when I say I’m fed up and want to leave they threaten a fee.

Hi Laurens,
We are sad to hear you are having a bad experience with us!
We understand your unhappiness about not having energy insights for your electricity usage. It is, however, standard procedure that a fine might apply when prematurely ending a fixed contract.
One of our Senior Service employees is currently in contact with you, regarding your complaint. They are discussing your case with management and will get back to you as soon as possible.
Hopefully we will be able to reach a satisfying solution!
With a smile,
Coolblue Energie
This is for cool blue airco. It takes forever for them to reply. Very slow, very poor attention for the client. Unclarity for the planning. We are already 2 months later than expected on the service and it is always me chasing them.
I’ve been using Coolblue Energy for a while now, and overall, my experience has been quite positive. The operation is smooth, and I haven’t encountered any major complaints. The service is reliable, and everything works as expected.
However, I do have one issue. The real-time daily consumption data is not visible on the website for me, which is quite inconvenient. Additionally, when I reached out to customer service for help, they were not very helpful in resolving this issue.
Despite this, my overall experience has been good, and I hope they can improve their customer service and website functionality in the future.

Hi Aminuddin,
A lack of insights is an issue we need to tackle!
We have been working hard on our applications, to improve the experience. Let's take a look at your issue, so we can find a fitting solution.
We are sad to hear you did not get far with our customer service, may we try again? We have asked for your personal information, so we can reach out to you.
With a smile,
Coolblue Energy
Do NOT get solar panels installed from Coolblue. Within months after installation, our roof started leaking and coolblue support has not been of any help. The damage company they hired to investigate this did not even go up the roof to check anything. They simply blamed bad weather without doing any check and asked us to contact the insurance company. This is just causing the delay in fixing and is making it worse.
Got a good price via Eigenhuis auction, so I can not say much about the cost. I get my electricity and gas like I expect, so that is normal.
What I miss is the lack of an informative and detailed webpage on energy use and cost, on at least a daily basis, both on Web and mobile. Their monthly report is only marginally useful.
Outstanding service and customer contact. Monthly ands annual summaries of energy usage are very useful. Prices competitive. We are two people in an apartment so energy use during warmer months is much reduced - this offsets the higher payments during winter.
Coolblue Energie Longer period of delivering Energy and Gaz to my. Very well supplied with monthly information, No issues, no surprises, clear contractual information. Hopefully a renewal can be arranged soon. Overall I'm a happy customer.
Very happy with them, emails about usage are insightful and relevant.
Otherwise I don’t expect too much from them 😀
When there was an issue with the power they weren’t very helpful- just sent us to our power provider.
This company is the best! It is easy to conclude a contract with them, they are responsible, they immediately added me to their list, there is a possibility of feedback and they respond very quickly. Because before I applied here, I tried to conclude an agreement with other companies and they lost my application there, the waiting time was very long, etc. Glad I found this company!
Great, competitive prices. Good, clear customer portal on the coolblue website. And great discounts on their energy saving products.
I was overcharged more than 1000 Euro and over 3 months later still no refund I must have to take legal procedures unbelievable
