Not the best app UI (many redundant pages trying to sell me smart home; UI isn't adjusted if my counter doesn't have one digit, but I need to leave it empty but not 0); probably not the best tariff (b... See more

The best provider for any student or a foreigner in Germany. They handled my contract change so swiftly, i didn’t have to lift a finger. Last year, they never sent an invoice/ deducted payments all ye... See more

Not sure I could ever really love a power company, but Ostrom is as close as it gets. I definitely made the right choice switching to a dynamic power supplier, and specifically Ostrom. Their busines... See more

I’ve been with Ostrom for almost a year now, and honestly, it’s been an amazing experience. Everything is super fast, smooth, and transparent. The app is hands down the best I’ve used; managing my e... See more

I just got onboarded to the system, and it was quite smooth. I added the meter number, waited a few days, and then received an email confirming I was fully onboarded. The referral system works a... See more

The switch to Ostrom was very seamless, transparent & efficient. I got timely emails on what’s happening and didn’t have to do anything. Their app tells me everything there is and how my consump... See more

My experience with Ostrom has been great from day one. Beyond the fact that it’s clean energy, what I really value is the level of transparency and control I have over my costs. Everything is clea... See more

I am still struggling to find the following : I have not received notification / account number of my registration. Don't know how do I get my monthly billing. I don't have access to my dashboard or... See more

It's impossible almost to speak to anyone in customer service. They dont reply to you in the app and then on the chat function it's extremely long waits, if anyone even comes. I had the same experienc... See more

I've been using Ostrom for less than a month, and so far, I'm impressed. Their application is user-friendly, allowing easy data input and management. The paperless enrollment process was quick and h... See more

My experience with signing up for Ostrom has been very smooth. Everything was handled easily through the app, and full support for the English language made the process convenient. Customer serv... See more

Very efficient, very convenient. No need to cancel your old contract by yourself, Ostrom will do it for you! The App is very smart and non-german speaker friendly. Highly recommended!

The registration and all important information is in English. This is a huge plus, compared to other electricity providers in Germany. Registration was quick and easy online. Everything was very smoot... See more

It was the easiest and the fastest way I could connect with an electric company. I was glad that there was no hick ups. Plus the availability of services in English helped me understand the offering b... See more

The whole process was very smooth. Ostrom took care of the cancellation of the existing contract. The initial impression is good, but its too early to comment on the quality of service provided.

It went overall smoothly, but it was difficult to reach somone as I had a unique situation that required human help. Responses via emails were unanswered and the only thing that worked was writing to... See more

The communication system is absolutely terrible! I’ve been trying to reach you people for over 2 weeks and NOTHING! No real response, just being dumped on some useless bot. It’s beyond frustrating and... See more

Ostrom needs to add a customer service phone number, or be able to answer chat questions within a day. Having to wait almost a week to get a proper response, with the consequence that the contract sta... See more

I signed up for new contract on Oct 28th and there was wrong information regarding meter. We responded immediately on same day and followed up every day through chat and email interface with No respon... See more

I'm quite disappointed. I signed contract with Ostrom because I wanted to use smartmeter. My apartment was built in Dec, 2024. I totally don't understand why the state grid said they couldn't instal... See more

We are being kicked out because we refuse to move our contract to the Simply Dynamic Tariff. We are in Simply Fair Tariff, and we want to remain as it is for now, but Ostrom is forcing us to accept se... See more

Horrible service. Customer service is the worst I’ve experienced so far. They fabricated invoiced and took money from my account without my consent, and they wouldn’t give it back even with proof... See more

Initially, I was quite happy with Ostrom. But now, it has become very difficult / almost impossible to reach any human agent there. I've made requests for an interim invoice for 9 days (which I really... See more

I am currently with them, i like that its all app based and its all in English. However their customer support is extremely bad, they take days to respond to a very simple question or query and thats... See more

Ostrom is by far the worst service provider I have ever dealt with in Germany. Their customer support is unresponsive, their process is confusing, and they show no professionalism when it comes to h... See more

I've been trying to change my meter number for a week now. The guide online doesn't work and it's impossible to get in touch with an actual person not just an AI bot. I've sent emails, written numerou... See more

It was a complete disaster! Ostrom made a new contract with an incorrect meter id. I have been reaching out to your company thru email, phone calls, live chat! Only a ticket has been created! I got n... See more

Single handedly the worst sign up process, customer service and responsiveness I have ever experienced of any provider anywhere. 4 weeks I was trying to sign up to Ostrom. Endless messages to t... See more

THIS IS THE WORST CUSTOMER SERVICE I HAVE EVER EXPERIENCED IN MY LIFE I had not electricity for a week and could not get a response from their customer service. I am amazed at how bad this cust... See more

I have been with ostrom for 2 years. All was ok until January when they made a disgusting move. Sent me a letter that my new monthly tariff will be 82 euros. Next month pushed this up to 10... See more

I’m writing to them for the last 1 week and no reply at all. They don’t have any phone number either. My problem is I registered with them and signed a contract 3 months ago in Munich and they st... See more

I am absolutely furious and done with Ostrom. Out of the blue, they sent me a threatening payment demand for some vague deposit with zero explanation, causing unnecessary stress and panic. When I aske... See more

Awful Awful, DO NOT REGISTER WITH THEM. I signed up a week before moving in (as soon as I had confirmation of the place) and started a contract with Ostrom, since I’d used them before in sha... See more

I am the client of OSTROM for 3 years. Recently they announced a legal entity name change from Nov 13. several days later I got the letter from our default supplier eon, that we are their clients... See more

First problem: I started a contract with Ostrom in August when I moved into my new apartment, and since then I haven’t been able to submit my meter reading. The app doesn’t allow me to, and whe... See more

Support has been one of the slowest I’ve experienced. My request has gone several days without any response, which was surprising given the many positive reviews here. I expected a much quicker turnar... See more

There is zero customer support. I am trying to connect with customer support from weeks but still talking with an AI agent who is not able to understand my email ID.

Poor customer support during change of address. Same experience with one of the review 6 days ago from the day of this writing. Based on the FAQ, you just need to send a request with the details... See more

This company works super efficient. Their pricing very fair and the best in the market to be honest. They are helpful, also the English app is great. I am very happy so far and recommend Ostrom 100 %.... See more

I am very disappointed with Ostrom. It is simply impossible to get in touch with their customer service. I have tried multiple times during normal working hours via email and other channels, but t... See more

It was really easy to move from my existing provider to OSTROM. Everything related to my older company cancellation process was taken care by OSTROM automatically. Thank you.
