Heliosx Limited Reviews 22

Vishnu was brilliant! Explained everything from the beginning and never pushed. He provided a great deal of information to make my own decisions. Eventually I ended up with a great energy system (solar and Tesla Powewall 3). His response time to my queries was excellent and you won’t see this nowadays. Humble and super cool guy. Would recommend to anybody. 5 star service undoubtedly. Thanks Vishnu.

thinking about onstalling solar

Heliosx Limited did an excellent job installing our Powerwall 3 with extension pack and 30 solar panels. Vish was professional from start to finish, always available to answer queries, and supervised each section of the project closely. He was genuinely helpful and made sure we were comfortable using the app/settings, and followed up to ensure everything was performing as it should. Pricing was very reasonable and his troubleshooting was spot on. They also left everything tidy and clean at the end of the job. Highly recommend Heliosx Limited to anyone considering solar and battery storage.

I received detailed and factual description of the solar installation and what I could expect . I had to change the date of installation and the request was accomodated . Installation was completed in a day and was flawless. What I appreciated most was the setup of the app and controls which was done the same evening. The system was up and running within an hour. Very good staff . Vishnu helped with everything .
Overall the service was excellent.

Very happy with the service and customer care. The journey to install our Pv and Ev system from quote to commissioning was with no stress. Saved by getting a good price. Highly recommend

From initial consultation through commissioning, Heliosx delivered a seamless experience. Vishnu led the planning phase with clear options and honest cost comparisons, which made our decision straightforward. Installation was efficient, the commissioning went without a hitch, and their aftercare has been responsive and helpful. Competitive pricing — truly one of the best value providers out there — and a pleasure to work with. Highly recommend Heliosx Limited to anyone looking for going green with Solar.

I had solar panels and a charger installed by this company, and the entire experience was excellent. The team delivered a high standard of service, always taking the time to answer my questions and explain things clearly. The installation process was smooth and professional, and the system has been performing perfectly since.

What stands out most is their aftercare — they continue to provide support whenever I have queries, ensuring I feel confident using the system. It’s reassuring to work with a company that values customer satisfaction beyond installation. I highly recommend their services.

The service was impeccable from start to finish and everything was so smooth from sale to installation. The employees were very helpful in answering all the questions we had and I can’t thank them enough for being of assistance. A special thanks to vishal who was very helpful in answering phone calls and dealing with all my queries!
Thanks,

Highly recommended

We had a large number of solar panels installed, as well as batteries, in July 2025,in Nottingham, from Helios Ltd. Vish explained everything in easy to understand english .All the equipment used is top quality. At the start of the process, the scaffolding was erected, then the next day came the solar panel installation team ,and then a couple of days later, the electrician arrived to put everything together. Everything went seamlessly, and Vish was available at all times, to answer your questions. I had two other quotes, and Heliox was way cheaper than the other companies,for the same job. I am very happy with the job ,and highly recommend Heliox.Vish made the whole process very easy.

I recently had solar panels installed and couldn’t be happier with the entire experience. Vishnu was absolutely fantastic throughout the process — super cool, friendly, and incredibly helpful at every step. He patiently answered all my questions, made sure everything was clearly explained, and ensured the installation went smoothly from start to finish.

It’s rare to come across someone so professional and approachable. Vishnu made what could have been a complex process feel easy and stress-free. Thank you, Vishnu, for your outstanding support and service!

Working with Vish was really easy. He’s flexible, reliable, and always quick to respond. His team is professional and did a great job. We had started our solar install with another company but ran into problems halfway. Vish stepped in, took over smoothly, and finished everything without any fuss. Highly recommend.

Mr Vishnu explained everything in detail before installation of solar panels, he made me understand and take right decision,
I had obtained 3 more quotes along with Vishnu quote, very competitive price and reasonable
Highly recommend if you are planning to install solar panels.

Very good service. Value for money with good quality products. Highly recommended.
