Heliosx Limited Reviews 25

Contacted Vishnu for a solar quote, and he provided a clear overview of different systems and pricing options tailored to my requirements. His prices were highly competitive, so I happily agreed and moved forward.
The entire process was seamless:
* DNO Approval: Handled quickly and efficiently.
* Installation: Completed professionally with zero hassle.
* Octopus Export: Fully set up and ready to go.
The entire project took less than 6 weeks from my initial contact to final completion. I am incredibly impressed with the speed and communication.

A friend recommended Heliosx Limited, and my experience has been excellent. Vish responded promptly to my enquiry and provided a competitive quotation for a system including 14 solar panels, an EP12 battery, an 6KW hybrid inverter, an EV charger, and a Myenergi Eddi solar diverter.
Vish was professional, patient, and thorough in addressing all my questions, and he was flexible in scheduling the installation to suit my availability. His team—including scaffolding, roofing, and electrical specialists—were courteous and highly competent. The installation was completed efficiently, with everything fitted correctly on the first attempt and without any damage. The team also ensured the site was left clean and tidy upon completion.
The overall standard of workmanship was excellent, and I am extremely satisfied with the outcome. I would have no hesitation in recommending Heliosx Limited to anyone considering solar, battery, or EV charger installations.

After having 14 solar panels and a 12kW battery installed by another company (RenergySolutions), I had a disappointing experience and decided to look elsewhere when upgrading my battery capacity.

A friend recommended Heliosx Limited, so I got in touch with them. Vishanu responded promptly and visited the very next day to assess my requirements. He is a humble, professional, and trustworthy person who took the time to explain everything clearly.

The installation was completed to a high standard and within the agreed timeframe. I am extremely pleased with the quality of the work, the excellent customer service, and the competitive pricing.

In fact, I am planning to have another 10 solar panels installed by Heliosx Limited in the coming months.

I am highly satisfied with the entire experience and would have no hesitation in recommending Heliosx Limited to anyone considering solar or battery installations.

This version reads more naturally and professionally while keeping your positive experience and recommendation intact.

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,

Reliable person and I appreciate his time over the weekend to sort out small glitch.
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!
