Customers of QUANTUM ELECTRICAL & SOLAR LTD often describe tidy, well-explained solar and battery installations, with several reviewers saying the team kept them informed and left the site clean. Mason is named by multiple reviewers for his detailed surveys and clear advice, and Steve, Jake and Will are each named in more than one review for their work. One customer says the system had generated 1330kWh in its first month and that they had not used the grid since installation, while another reports relying almost entirely on solar power since installation. One reviewer describes a previous installation by a large energy provider as completely mishandled, which they contrast with their experience of Quantum.
Great service from Quantum installing our solar panels. Especially from Steve the electrician who went over and above I what turned out to be a larger than expected job!

Jake and his team were great He explained everything and made suggestion to make the job look nice Roof team friendly and efficient Very happy
Great service and instillation from start to finish. Highly recommend
With solar panels, clean energy isn't theoretical - its a 'Quantum' leap forward to the future!!!! I had done my research and spoke with several companies and to be honest it was not any easy choice who to go with. However after speaking with Mason and Harry I knew I had made the right decision to go with them. I had lots of questions about what I could and could not do and what my system was capable of. Mason was always on the end of the phone and more than happy to listen and offer his advice a experience. I am more than happy with the service from start to finish, clean, hard working and great installation. It has been exactly 1 month and my system has generated 1330kwh I haven't used the grid from the day of intall being completed. Overall I am 1 very happy customer. This isn't a small change, it's a 'Quantum' shift in the right direction!!!!
Very professional and a clean and tidy workmanship
The experience was slick and very professional. The install was neat and cables have been hidden away, and the installis exactly how it was planned. The results are saving me money from the moment it was switched on as per it was explained to me at the survey visit. I am very pleased with the result. I would recommend this company. I had 5 companies quote for the work and using AI looking on line and in the public domain Quatium came top for professionalism, value for money and top quality craftsmanship. This was another my reason for my choice as well as the good advice about what I do and don't need. They sold me a product that I needed and not to just to sell me products to make money.
Jake made a great install for me with the SigEnergy. He came in, explained the work to be done, and cracked on. Checked in regularly and helped me set up the app and explained the basics well.
I had such a good experience with Quantum Electrics and Solar. After a previous install with a large energy provider that was completely mishandled, honestly, it felt like a breath of fresh air From the very start, everything was done properly. Mason came out for the initial survey and spent well over an hour going through my setup in detail. He looked at our energy usage and then built a system around that. What stood out most was how honest he was. He clearly explained what I needed and, just as importantly, what I didn’t need. He stopped me from spending money on unnecessary extras like the gateway, which I really appreciated. The system he recommended, including the Sigenergy battery with AI capability, has been spot on for me. You can tell it wasn’t a one size fits all approach. The whole process moved quickly too. The DNO application was handled far faster than I’d been told to expect. Other companies had quoted over four weeks, but this was sorted within a day. Communication throughout was excellent. Everything was clear, organised, and exactly as promised. When it came to the install, Harry and team were brilliant. Polite, conscientious, and really hardworking. Nothing felt like too much trouble, and everything was completed aesthetically and functionally to a very high standard. I also asked them to replace my electric consumer unit at the same time, and that work was done just as well. It’s rare to find a company that gets everything right across the board, but they really did. Aftercare has been just as good, which makes a big difference. I’ve already recommended them to several people and wouldn’t hesitate to recommend them to anyone looking for solar.
I couldn’t believe it when I requested a quote and none other than Joey Essex turned up at my door to do the survey. I used to watch The Only Way Is Essex back in the day and it’s so nice to see Joey has now got a trade under his belt. How could I not give five stars! Keep up the good work Joey!
I spoke with at least 5 providers when making the choice. What stood out was Mason and the team’s knowledge, total professionalism, desire to do a first rate and aesthetically neat job whilst not trying to push a sale. The after install is first rate and they help you optimise return through tariff selections. The Q Code pack is an innovative idea so all the key info is readily accessible. I had a slight reservation when selecting as they are a relatively new company (c.5 years)- this is actually a plus point as they want to a do a great job to build their reputation. They also employ a young and keen team which is another plus for me. The products are excellent with long warranties for peace of mind. They weren’t the cheapest, but their customer service and enthusiasm tipped it in their balance for me and I have zero regrets in choosing them.
After spending a considerable amount of time with Mason—both in person and through detailed conversations over text—carefully discussing my requirements and exploring various ideas, choosing Quantum became a very natural decision. Mason demonstrated exceptional patience throughout and was entirely aligned with my thinking, ensuring that every aspect of the decision was approached correctly and without pressure. As a tradesman and business owner myself, I’m particularly attuned to professionalism and standards of service. It was immediately evident that Mason has a genuine passion for his business and a strong commitment to delivering outstanding customer service. What stood out most was the absence of any sales-driven nonsense—just clear, honest, and upfront advice, with pricing exactly where I expected it to be. This ethos was consistently reflected not only by Mason, but throughout his entire team, which was genuinely impressive. Once Blake and the roofing team had completed their work, Jake and Will undertook the electrical installation. Their work ethic, pace, and attention to detail were exceptional—qualities that are increasingly rare to see. I hold very high standards, and they exceeded them without question. Helena in the office was also exceptional with her communication and professionalism. Overall, I can confidently say this has been the best experience I’ve had with any company in a long time. From initial consultation through to final execution, the knowledge, communication, and quality of workmanship were faultless. The system itself has performed brilliantly, we’ve luckily had consistently sunny conditions, we’ve relied almost entirely on solar power since installation, only drawing from the grid to charge our EVs. I cannot speak highly enough of Quantum. I would strongly recommend them to anyone considering solar installation. This is a highly professional, well-managed, and exceptionally efficient operation—you will not be disappointed choosing Mason and his team. Thanks once again to Quantum Solar Ltd.
Quantum were from my first contact with them to the point of full install, were very approachable, responded to queries promptly. When the install date was agreed, it was attended to from the point of delivery of the Solar PV, Batteries etc, to the install of the panels as well as batteries. The work does was excellent and they responded well to my requests to what equipment should be installed where. I would not have any hesitation in recommending Quantum Solar to my family and friends. Excellent company to interact with and they have very knowledgeable staff who work for/with them.
We selected Quantum for our Sigenergy solar and battery installation for a few reasons. Mason was very knowledgeable when discussing our requirements and understood exactly how we wanted the system to be installed. We were able to easily make a couple of changes that included adding an EV charger and extra battery to the Sigenergy system. Overall, we are very impressed with the excellent quality of work and with the installation team leaving the site clean and tidy. Good support from Mason throughout the process from initial meeting, installation and post completion to discuss suitable energy tariff options.
Had been thinking about solar for a while when came across Quantum Electrical & Solar. Leading lights in the business are Mason and Harry both of whom are registered National Inspection Council for Electrical Installation Contracting electricians and the company is accredited under the Microgeneration Certification Scheme. Mason designed my system and he was very switched on as to orientation, panel placement, equipment placement etc basically totally across the project. Mason is a delight to deal with enthusiastic almost to anorak degree (although he doesn’t wear one!) and 100% focused on using his expertise to produce the best possible system. The system was installed by Harry and his team including Will and Jake in a day. They were skilled, polite, tidy and hard working. The result is fantastic, Sigen inverter and 20kwh battery, AI managed. Extraordinary how it can pick up so many kW when you can hardly see the sun and it’s cold! The AI management just generates savings and profits constantly including emptying the battery late in the day to export at 0.15p per kWh, using the solar to always serve the house first and export surplus during the day making profit from solar and battery charged at 0.08p per kWh off peak rates and exported at 0.15p per kWh. Solar is a win win, save the world and save money and Quantum Electrical and Solar will get you to the right place.
Amazing service and after care highly recommended
Mason and the Quantum team were excellent throughout the entire process. Mason was very professional during the initial survey, clearly explaining how everything would work and what the next steps would be. The price was very competitive, and the installation was seamless—from the erection of the scaffolding to its removal. The installation crew were highly professional, and the whole system was installed and up and running within a single day. The use of the app and the next steps were also explained very clearly. Overall, it was a great experience, and I would highly recommend them.
As a returning customer, I recently had Quantum Electrical come back to add 3 battery slaves to my existing Fox cube setup. The team was professional, efficient, and explained everything clearly along the way. The job was done neatly and on time, and the system is performing brilliantly now with the extra capacity. Really happy with the work and the ongoing support—highly recommend them for solar and battery upgrades!"
Quantum provided us with a large solar panel installation tied to a Sigenergy battery and gateway in Feb 2026. From quotation to installation it was a fantastic experience. Nothing was too much trouble for Mason and his team. Very professional and no hard sell. All installed in two days and then the scaffolding came down pretty much immediately. We’re now seeing great PV production even though it’s still winter. Well done Quantum!
First class service from the team, look no further for electrical and solar needs
Very happy with the advice and install, clean tidy and professional fitted in one day, well done Quantum
We were very impressed with the time Mason spent ensuring we were satisfied with the proposed setup. The installation itself was highly efficient, and the support we have received since then—both with using the app and configuring the export—has been excellent.
Quantum Electrical Solar Ltd professionally installed my solar panels, and I couldn’t be happier with the service. I would confidently recommend them to all my friends, family, and anyone who ever asks me about solar panels. I had my solar panels installed 7 months ago, and even now their customer service is outstanding. They still reply to all my messages within the same day and remain incredibly helpful whenever I have questions. That level of aftercare really sets them apart. Reliable, professional, and genuinely supportive from installation to long after—highly recommended.
Mason and Quantum were absolutely top notch from start to finish. Mason was completely thorough when he came round for the initial consultation and not pushy like some of the other sales people we came across from other companies. The price was extremely competitive and installation was quick and seamless. After the installation, Mason was also really helpful in advising on getting our tariffs set up and switching. Would definitely recommend!!
Quantum installed our electric vehicle charger professionally and with clear attention to detail. They took the time to assess our setup properly, explained the available options clearly, and shared useful information without any sales pressure. The installation was carried out with care for our property, kept clean and tidy throughout, and completed at very good value for money. I would recommend Quantum for their knowledge, fair pricing, friendly approach, and overall professionalism.
I have used Quantum for a number of years now on a variety of fit-out projects and they are an excellent company to work with. Their quality of work, attention to detail and customer service is really impressive. The whole team is very professional and attentive. I would highly recommend to anyone!
Honest and Trustworthy Mason was very knowledgeable and was impressed with the time he took to explain the process and the options available. The drone to view the roof was the attention to detail I had not been given by other quotes. The competition used google street view which does not provide a detailed view. Mason was able to confirm exactly what system would fit and provide the maximum generation. His fitters worked efficiently and cleared up afterwards. The weather was cold, wet and windy but that did not deter them. Jake especially did an excellent job. The system is now up and running and look forward to the benefits of solar. Mason has been particularly understanding and is on hand to sort out any issues. I have no hesitation in recommending him as there are some dubious sales techniques adopted by other organisations but he was honest and took the time to explain how it will work with no hard selling.

🌟 Outstanding Solar Installation and Service by Quantum! I wholeheartedly recommend Quantum for anyone considering solar. From start to finish, the experience was 100% positive. The installation crew, led by Mason, including Jake and Harry, was incredibly clean, professional, and on time. They showed great care for my property throughout the process. The all-black panels look fantastic, and the battery and EV charger are performing perfectly, already making a noticeable difference. A huge shout-out to Helena in the office, who was quick and efficient in answering all my queries. The team also provided a clear explanation of the system and the app. If you are looking for a local company with top-tier installation and customer service, choose Quantum!

Highly Recommend Quantum Electrical and Solar I recently had EcoFlow solar panels and an Ocean battery system installed by Quantum Electrical and Solar, and I couldn't be happier with the entire experience. I'd been searching for solar and battery solutions for a while, and Octopus Energy put forward a few options to choose from. From the very first contact, Quantum stood out. The team were polite, enthusiastic, and genuinely knowledgeable—there was no pushy sales approach, just helpful advice and excellent literature to help me understand my options. As approved installers, they offered very competitive pricing with a clear, straightforward proposal. The payment schedule was easy and fair, and there were no unexpected extras along the way. The whole process ran smoothly. A couple of minor issues arose that were completely outside their control, but these were managed efficiently and promptly. I was particularly impressed by how quickly the power network applications were completed—unbelievably fast. Communication was excellent throughout, with regular updates at every stage. When it came to the installation itself, the work was tidy and professional. The team cleared up after themselves and left everything spotless. I really can't recommend Quantum Electrical and Solar highly enough. If you're considering solar panels or a battery system, look no further.
Had solar, battery, EV and inverter installed. Done very smoothly and always happy to help answer questions. Would recommend
The service we received from Mason and his team was outstanding. They listened to what we required, and gave us the advice as to the system we needed. Installation from start to finish was excellent and any questions we had were answered. Their response to any communications were quick, with full explanation of how these systems work. My recommendation is just give them a call; you will not be disappointed!
From getting a quote to doing a site survey all questions answered without any hesitation completely great people with a passion about thier company very friendly people definitely recommend them and very good installation neat and tidy craftsmanship you can tell they definitely take pride in thier work.
Mason From start to finish perfect. No question unanswered.Great communication when designing the system, installing and aftercare. If your looking to go solar or battery give quantum a call very highly recommended.
Mason has been brilliant, from the 1st call to fully installed. He kept us fully informed at all stages. Any questions we had, was only too happy to answer and advise. No hesitation in recommending Quantom Ltd. Keep up the great work Mason!
I reached out to Quantum for a solar panel installation quote. I was in a hurry due to requirements stipulated by planning and couldn't sell my property without it. Quantum managed to quote me quickly and at a fair price They even managed to do all the works completed within 1 week. I would highly recommend them. All the works were done tidy and the property left as they found it.
We recently invested in a solar and battery system (June 2025 installation) and we couldn't be happier that we made the move to solar energy and specifically that we engaged with Quantum as our chosen provider. We valued the fact that Mason was involved in the entire process, from initial explorative discussions through to the installation and subsequent aftercare. He was readily available to answer all of our questions and took the time to provide us with the information and talk us through options. We didn't feel pressured to go ahead and there wasn't a hard sell at all, just the chance to gather enough knowledge to make an informed decision. We both felt that we built up a rapport with Mason which even extended to a game of golf that he was kind enough to host, further cementing the trust we had in him and the business. When the installation date came everything ran very smoothly and Mason and Jake impressed us with their professionalism and efficiency. We were really pleased with the EcoFlow system and love how easy the app is to use and keep track of things. Would highly recommend the Quantum team!
Mason from Quantum Electrical Services is a diamond of a find. Moved home recently, wanted someone with knowledge of Solar panels as ours didn't work. Within minutes of arriving Mason found a problem. He explained everything so clearly. We now have working Panels and battery, all fitted properly with certificates and monitored in case of future problems. Quick, tidy and very efficient. Highly recommend for any electrical work.
We cannot recommend Quantum Electrical services enough. We had been considering installing Solar on our house for some time and had spoken with other companies before meeting with Mason. Mason from Quantum spent a lot of time with us in order to fully understand our needs before designing a bespoke system and putting together a detailed and comprehensive quote for us. Both he and his team showed an in-depth knowledge of the system they were installing and a genuine interest in their work. They were clean and tidy on site, nothing was too much trouble and they completed the installation on time. Mason has continued to monitor our system and follow up with us since the installation to make sure we are happy, and everything is running as it should be. More companies should be like this.
Mason was extremely patient when explaining everything to me for which reason I chose his firm. The service offered was friendly and efficient and, despite the bad weather, was speedily accomplished. I would recommend his firm wholeheartedly, it was superb.
The whole experience with Quantum has been great all the way through with Mason one of the Directors project managed the whole process, from site survey, quote etc, ensuring that ALL went smoothly even including the scaffolding being erected just before installation and removed on the final day of installation! The whole experience has and is very positive and I recommend them to anyone considering solar panel/battery installation. I am unable to comment on the feed in back to the grid yet but this is ALL down to Octopus Energy dragging their feet, all eight of them I think!! We’ll done to all at Quantum Jeff A
