Written by the company

Upvolt helps homeowners take control of their energy with smart solar, battery storage and home energy management systems designed for your home. We know installing solar or upgrading your home energy system can feel confusing. There are lots of companies, lots of products, and it’s hard to know who to trust. The industry has become a race to the bottom in many places, with systems installed quickly and support disappearing afterwards. That’s not how we work. We provide a full end-to-end service, from system design and installation through to grid connection, monitoring and long-term support. Our goal isn’t just to install a system, it’s to build something that works for your home and continues working for years to come. Our regional teams bring over 15 years of experience in solar and home energy systems, combined with the support of a wider national network. This allows us to deliver high-quality installations while still providing local service and ongoing support. We believe homeowners should feel confident and informed when making decisions about their energy, not pressured or confused. That’s why we focus on honest advice, quality installations and long-term customer support. We’re not just here for the installation. We’re here for the life of your system.

Usually prompt communications

Usually prompt communications - this year’s ASHP Certificate is much less informative than previous issues. Email advises “an expiry date listed on certificate” there is no expiry date!

OHM Energy - Can't fix "complicated" water leak and charged for NOTHING

OHM Energy were called to investigate my hot water not heating up to temp. They charged me £305 never fixed the problem and gave me completely false information, which I assume to justify their charges. They said I needed to change a 3 way port valve which cost me another £280. All a load of rubbish. Called a local plumber, who reverted back to the OLD 3 way port valve as nothing wrong with it and found the actual issue which was a simple hot water leak. They company will claim my system is "complicated", I would suggest to OHM Energy if it is "complicated" then maybe they should try another business. In addition to that, if you can't find the fault, don't just make things up and incur more cost to your customer. Walk away with your call out charge and be happy. Waste of money.

Great solar engineers and support

Booking an engineer was very easy, despite how close it was to Christmas when I contacted them. The engineer arrived early which I appreciated. Work was done quickly and to the original price, they also gave me advice on my system and works that may be needed down the line.

A follow up on my previous review.

A follow up on my previous review.
They have now admitted that there is a problem with my charger!
Instead of charging 6p a KW between 00:30 and 04:30, which is what I set the price cap at, it's still charging me 14p a KW twice as much!
I have asked for a refund, this has been going on since December last year, won't hold my breath BUT I will NOT give up.

Hello Linda,

It looks like this review may have been posted to the wrong company. We are OHM Energy, a UK-based renewable energy installer based in Sussex.

We're not affiliated with Ohme, the electric vehicle charger manufacturers. We'd encourage you to contact Ohme EV directly or repost your review on their Trustpilot page.

Many thanks,
The OHM Energy Team

Look no further :Here`s OHM !

OHM have been supportive of us as customer throughout, keeping us informed about the work they were carrying out, notifying us well in advance, of any disturbance the ongoing work might cause to the community.OHM worked as quickly on our large field of solar panels installation as circumstances permitted.
Excellent value for money.

Exceptional Service

This is the copy of the email I sent to to OHM team after my install was finished, they are a great company.

Hello, Robyn, Emma,Urszula, Agata, Matt, Dylan, Oscar, I wanted to take a moment to express my sincere gratitude and satisfaction with the exceptional service provided by your team during the installation of solar panels and a Tesla Powerwall battery system at my home.

From the very beginning, the experience with Ohm Energy has been nothing short of outstanding. Matt, as the lead installer, and his assistant, Dylan, displayed an impressive level of professionalism and expertise. Matt's initial assessment and guidance helped me make informed decisions during the install process.

Dylan, I must commend you for your hard work and dedication during the installation process. Matt your commitment to excellence and meticulous approach to the wiring and overall installation made a significant impression. The final result not only met but exceeded my expectations. The entire installation is incredibly neat and tidy, demonstrating your commitment to quality workmanship.

The addition of the solar panels and Tesla Powerwall battery has already had a positive impact on my home's energy efficiency, as I write this the solar system is producing 3.0kW and my wife has finished two loads of washing whilst we have imported nothing from the national grid. I am excited to contribute to a more sustainable future, thanks to the top-notch technology provided by Ohm Energy.

Ohm Energy's professionalism, punctuality, and commitment to customer satisfaction are truly commendable. You have made my wife and myself transition to renewable energy a smooth and enjoyable process, and I couldn't be happier with the outcome.

I want to express my thanks to the entire Ohm Energy team, especially Matt and Dylan, for their exceptional work. I am delighted with the installation and your service, and I would not hesitate to recommend Ohm Energy to others seeking similar energy solutions.

Thank you once again for your outstanding service, and please keep up the fantastic work. I wish Ohm Energy continued success in providing sustainable energy solutions to others in Eastbourne and surrounding areas.

Excellent customer service

We received speedy, helpful support when we had an emergency.

The technician helped us to get our water supply going and how to manage the system to help the house work okay. We were able to communicate via video link and he guided us through the checks and found the problem. He phoned us back to check the system was operating okay and came out the next day.

OHM is fantastic

OHM is fantastic. They've done my Heat Pump, my Tesla Powerwall 2, my 22 solar PV panels, and some major electrical reconfigurations to handle everything. In my opinion, I have no hesitation in highly recommending OHM Energy.

Excellent customer support

A smooth sales process is great, but what happens further down the line is what really talks for me. We were really impressed with the support and customer service from OHM when this was needed recently. A particular mention goes to Keith, who was helpful, proactive, and generally very pleasant to deal with on site.

Ohm replaced our gas boiler with an air source heat pump with quite a bit of upgrading being needed to our hot water system. Everyone I have spoken to has been very friendly and helpful, especially the team that did the work. A couple of minor tweaks were implemented very quickly. Well done to everyone at Ohm for providing such a good service, particularly considering how busy they are.

Very pleased with OHM ENERGY from start to finish. Colin came and done the survey with an obvious knowledge, but wasn’t your normal pushy salesman. The quote came quickly and and still no pressure on us to decide. The 2 chaps who done the installation done the job with a smile and were very clean and tidy on site and when it was going to be noisy let us know so we vacate if we wanted. They were happy to answer any questions I had and did a very smooth and professional job. I have nothing negative to say and would be happy to recommend them.
