Evaluating 36 reviews, reviewers overwhelmingly had a great experience with this company. Consumers consistently praise the staff and technical team for their exceptional helpfulness, professionalism, and positive attitude during every single scheduled visit. Property owners frequently highlight that the assigned engineers are extremely knowledgeable, take ample time to explain technical details thoroughly, and always leave workspaces impeccably clean.

A few reviewers expressed annoyance regarding unreturned inquiries and the extra personal effort needed to resolve post-installation paperwork without timely professional assistance.

Keith came and serviced our Ashp today, made a few adjustments, noted that there needs to be more pipe lagging and loft insulation needs to be put back after installation. Great job.

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.

Keith was the consummate professional as always with our latest service. We’ve been using these guys for four years or so and they’ve always been great.

After an initally great customer…

After an initally great customer experience
we have a functioning system and after 3 years since fitting it produces a good amount of electricity. HOWEVER I have a fault in the indication system, in that our main array shows a double reading for that inverter. We have also never received the MCS certificate for that array from DEEGEE who have now changed their name to Upvolt Kent.
This business appear to be great with the instals but the all important legal paperwork (MCS/DNO) they often have to be chased and tend to seek it after installation (DNO) rather than before.(See other reviews) The director said to me on the phone that they never get turned down for smaller installations with retrospective applications.
I have attempted to contact Upvolt Kent multiple times with no response, as Deegee Victoria was good with recent communication (getting our 3 years late DNO approval, something the salesman said would be done before the instal). This was also an issue when they were Deegee, getting in contact and getting them to respond was very difficult (but not impossible). Really unhappy as we had a great relationship with them when we had a lot of issues with the initial solar edge installation, but I am really sorry to write this but given the distance from Ockenden to us (Cornwall) we are now an inconvenience to be ignored, we have no MCS for our main array, that is not acceptable.

Still waiting MCS and completion documents

The initial conversations were great. Installation booked and sorted. Had a problem on the day with battery not communicating with inverter but I resolved that later and bird netting was forgotten but rectified before scaffolding went.

Received DNO a few weeks ago with installation backend of April. Since then I requested the completion documents and warranties as well as MCS certificate but I keep being told there’s a delay. We’re over 2 months after installation and not received them after sending payment after installation.

Keith came to service our Mitsubishi…

Keith came to service our Mitsubishi heat pump and found a few items that needed to be fixed. He was very knowledgeable and professional. He said he will visit a few times at the start of winter to make sure all is running efficiently in real time. It was good to find a local engineer that will support as and when we need it. Highly recommended Keith.

We had to arrange another visit and Shontel was very helpful and organised the follow up visit with Keith once the parts were in.

Heat pump annual service

Keith arrived today to service my air source heat pump for the first time. He was helpful and efficient, and gave me useful advice on maintaining the pump. It's reassuring to know that Upvolt will be there to help if I ever need it.

Shontel and Keith were brilliant today a credit to the company.
Shontel for arranging our repair at short notice and sourcing the part for our heat pump.
And Keith for carrying out the repair in a thorough and efficiant manner, explaining to me what he was doing in an easy to understand way.

A professional and reliable company

The previous company that we used to service our air source heat pump and boiler ceased trading so I approached Upvolt. What a superb company. They dealt with my request promptly and efficiently. They were transparent about costs and they sent Keith. Keith is an excellent and experienced engineer who was very diligent in ensuring that our aging system was working well. He was courteous and explained everything in a non patronising way. He worked cleanly and efficiently.
I am happy to recommend .

We have used Upvolt for many years

We have used Upvolt for many years, installing our heating system in our self-build. We have always been impressed by the professional nature of the team from the office to the engineers. We now use Upvolt to continue the servicing on the ASHP system. Keith is always polite and efficient, leaving the workspace clean and tidy. Any work that needs done is always well explained.

I very rarely give reviews, so sorry

I very rarely give reviews, so sorry, but their company email address bounced and phone number didn't go through. I was messaging after work at 5.30pm ish, but they didn't allow me to leave a message or send an email for them to receive tomorrow. Just seemed odd, so sorry if they're a nice company.

Also the only company that quoted me solar panels without offering to view my house in person, which made me nervous X

Hi Rebecca, thank you for taking the time to leave a review. We’re sorry to hear you experienced difficulty getting through to us.

We’d like the opportunity to look into this properly. Our usual process involves providing an initial quote, followed by a full site visit and survey before any installation work is carried out, so we’d like to better understand what happened in your case.

Please contact our support team at support@upvolt-energy.com and we’ll be happy to investigate this further and respond directly.
Thank you again for bringing this to our attention.

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!
