Spirit Energy

Spirit Energy installed additional solar pv panels to the ones they installed back in 2012 and additionally a Tesla 10kw storage battery. The work was carried out, as expected, in a professionally manner with a minimum of fuss and disturbance. The installation itself is neat and tidy and is working more efficiently than we anticipated. The system is providing cheap energy to drive our heat pump and is now,in the summer months, exporting energy to the grid. A win-win!

Spirit Energy installed my 13.5 kWh Tesla Powerwall 2 battery in November 2021. The team that carried out the installation were thorough and professional and since then I've had trouble free service from the battery. Along with a 4kW solar panel array installed previously by Spirit Energy and the battery, my energy bills have reduced as during the "sunny" months I use no energy from the grid. All my household appliances are electric and I use an immersion heater for hot water. It is only during the colder winter months that I use gas from the grid for the hot water and central heating boiler. As you can tell I have been very pleased with Spirit Energy.

Spirit installed 10 LONGi 490W mono black solar panels with a bird mesh and a Tesla Powerwall 3 and Tesla Backup Gateway 2 battery storage system, on my property in March 2026, which was state of the art at the time of ordering in September 2025. This also included it being wired in such a way to allow the option of expanding the system in the future. I am extremely pleased with the result. In fact, I would say my property looks better with solar panels on it and so far the system has been very good. Spirit went above and beyond to maximise the return from my roof space and give me the best possible value for money, to ensure I received the most beneficial long term financial investment. Spirit is the Rolls-Royce of solar panels and battery storage installers, and Spirit’s name certainly befits Rolls-Royce’s emblem. I was taken aback and astonished at how good Spirit is and I would wholeheartedly recommend them to anyone. If there was such a rating as a Six Star Review, I would give them that instead, which is something I have never said before. A big thank you to the Technical Designer Tok, the Head of Residential Nathan, the Senior Electrician Simon, the Project Manager Dimitrios, the Roofers Jozsef and Rob, the Electricians Dan and Brandon, the Financial Assistant Fig, the Head of Customer Experience Ronnie and the scaffolding subcontractor JCR Scaffolding.

Really helpful people in the middle of a major retro fit and family illness. So flexible and understanding- highly recommended.

My system was installed in January 2023 and has been running perfectly for 2½ years. It comprise three solar panels and 13.5kWHr Tesla Powerwall2. Given that I get electric car charging rates from Octopus Energy, I use overnight electricity to top up the battery (plus solar) and never pay peak time rates. Apart from car charging, I use about 7kWHrs a day to run the house which is perfect for my system design. Lat year my solar panels generated just over 1MWHr of energy which represented about a quarter of my total electricity usage (including car charging). I chose Spirit Energy through a recommendation from Tesla UK and had no previous knowledge of them. I feel I made the right choice as their performance in understanding my requirements and the design of a system that matched this was really excellent. The quality of installation and commissioning work was professional and I have experienced no problems since it was installed. We have lived through a number of electricity feeder issue in our road and each time the Powerwall has isolated itself and then resynchronised so we did not notice the failure. They are a great company to work with and I am very happy to recommend them for their professional engineering and installation skills.

I have been really impressed with Spirit Energy team. I had 18 panels and Powerwall 3 installed two weeks ago. From design to commissioning the process has been smooth, overcoming complex challenges which has resulted in a neat install with minimal issues. - No issues with scaffold - No issues with mounting and installing panels. I was worried about cables under the panels and bird mesh on some of the corners not flush to tiles but have been assured these are not issues - Powerwall 3 install and wiring in the garage is neat and hardwired to my router - Wiring from garage to the utility, on the other side of the house is neat. - Wiring of the gateway in the utility is neat. - Commissioning and handover was thorough with all the documents post install received prior to paying remaining 10% of my invoice So far, no issues with wind, rain and the system is running well. Can't wait to export! BIG THANKS to Tok, Matt, Sam, Ari, Harry, Peace and Justin for being patient with all my questions. Matt especially took care to understand my concerns and step me through every inch of the install. Thank you

I cannot speak too highly about Spirit, who were professional, courteous and responsive throughout the whole process from initial inquiry, design, installation and post-install follow-up. I've been using the system without fault for over a year now, and it has generated in line with Spirit's very realistic predictions that were incorporated within the quote and the estimated payback periods. All their staff seemed to be very expert at what they do, and there were no faults at all throughout the whole process, all of which was taken care of by Spirit, such as arranging scaffolding, etc.

Spirit Energy arrive to fit a Powerwall 2 with non back up gateway in Aug 2019. My first impression on meeting the engineers was how professional they were. They explain the install, ask where I would prefer it fitted, advising on the best location. The chaps took most of the day doing a very neat installation and then downloaded the Tesla App and explained its use. I've been so impressed by the Powerwall and the savings I’ve made that in Aug 2023 Spirit energy installed a second Powerwall 2, this time I had the full backup gateway fitted with it. I now have a heatpump and my word, having the two Powerwall has made a huge difference to my energy bills. Would I recommend Spirit Energy? Absolutely. They may not be the cheapest but as I’ve learnt in the past, buy cheap buy twice. As for the Powerwalls I can’t fault them, they just run in the background charging on cheap rate power and discharging during the day. What’s really clever, if you have solar, the Powerwall will charge fully at night when there’s little solar during the day. In the summer, when lots of solar is available, they partially charge at night to leave space for solar.

Spirit Energy did an excellent job of our solar panels & battery installation, from initial contact, through quote, site visits, and the onsite implementation. At every stage they provided a professional service with good communication and assistance with any queries or problems that arose throughout the process. They are not the cheapest, and stated this from the first contact. However I consider that it was well worth paying more for the peace of mind and high quality of the work. They also provide an insurance policy (HIP – Home Insurance Policy) against loss of deposit and the risk of their no longer trading, so that their warranties are guaranteed (up to 10 years). This is why they cost more. The GivEnergy system has worked reliably, and in conjunction my Hypervolt Home 3 EV charger and Octopus Intelligent Go tariff, has resulted in a huge reduction in my energy bills and motoring costs. I have found ways of using the system to move 93% of my electrical consumption into the very low cost 6 hour overnight rate from 11:30 to 05:30. During the summer months, with good solar output, I affectively have free electricity and motoring. My latest monthly bill (April 2026) estimates my annual costs as £496.77 for electricity and £319.09 for gas (I still have a gas cooker & gas central heating, although this is used far less now that I have installed an overnight storage heater, an infrared heater in an outhouse and an air to air heat pump system for air conditioning and heating).

Spirit Energy installed 16 solar panels, associated equipment and Tesla battery at our home. The service was excellent and the team did a great job. The perfomance of the panels has been very much in line with projections and we now import very little power from the grid. We would certainly recommend Spirit Energy to anyone contemplating the installation of solar panels.

I contacted Spirit Energy with fairly fixed ideas on what I wanted. I got a quote for exactly that with very good data on expected performance and how the roof would look with the panels fitted. The salesmen then suggested a much better optimised system and explained the advantages of this and it's better return on investment. I decided to accept his better proposal. During the survey, I was guided through the installation and we mutually agreed on the position of the components and the cable runs. The engineer doing the survey was very experienced and helpful throughout. A few days after the survey, I was contacted by a lady who introduced herself as my project manager and she kept me well informed about progress and timings. Finally, the installation crew were very efficient in their work and during the commissioning set up my control of the system using the supplier app on my phone. All of the people involved are directly employed by this family-owned company and the only subcontractors used are the scaffolders. Everyone was efficient and helpful throughout the whole process. Now, over two years later, my system generates about 10% better than forecast and exceeds our consumption twice over. Overall, I think I could not have chosen a better company to work with and highly recommend them.

Install of solar panels and battery. The work was carried out as promised and in a neat and tidy way. All the staff I interacted with were friendly and helpful.

Spirit energy installed my Solar Panels in a professional manner. Operators were helpful and I was kept informed at all times. When a problem was identified with the wiring the company took responsibility without any fuss and the problem was put right quickly.

Spirit Energy installed our solar panels 4 years ago. Before installation I had lots of discussion with them about the technical details and they were very knowledgeable and helpful. Before and during installation they kept me informed about what would happen and when and they stuck to the schedule. The work was carried out with minimal disruption to us and the installers were friendly and respectful. The solar panels have and still are performing very well and are reducing my electricity bills considerably. As we have a heat pump, this is a major consideration. The heat pump works well with solar, particularly as the heat pump is managed with a Homely smart hub and can come on when there is good solar generation. So bill reductions come through optimising the use of solar electricity generated as well as payments for excess solar exported.

No problems with my installation - everything continues to run smoothly. 24Mw/ hr generated so far. Average combined elec / gas bill each year is now approx £400 ( including standing charges) - 3 bed detached house - 1 occupant. I do have air to air heatpumps & use the battery to spread the load over the day/night to utilise cheapest electricity rates ( especially in winter!)

This is a relatively low-cost item that did not justify scaffolding to replace. After several discussions and a site survey, three technicians were able to access the affected panel and optimiser from the adjacent loft window. They did this safely and quickly. Very good service from Spirit Energy.

We started our renewable energy journey with Spirit Energy in early 2021 when we engaged them to plan a solar and battery system for us. We were impressed with the thoroughness of the assessment of our needs and the resulting options offered. We started with a combined solar PV and battery system; the solar was installed in June 2021 and the battery in February 2022 (due to availability issues with the battery system). We were so pleased with the performance of the system that after more calculations and discussions with Spirit, we added a second battery which was installed in February 2023. The system has been running since then with no significant issues and reduces our electricity cost by around 80% every year. As of the date of this review our total savings have been over £7,500 (we are a high usage household). We have been very pleased with Spirit Energy from initial consultation through to installation and subsequent support and we'd certainly recommend them to anyone considering a solar and/or battery system.

In 2020 I approached Spirit Energy about solar panels and a battery - from the very start the service has been excellent - never too busy to answer, some very stupid, questions. The team explained everything clearly and all elements of the project were communicated clearly. I went ahead with Panels and a single Tesla battery - installed neatly, on time with no fuss and the team made an excellent job of tidying up . Since the original installation, they continue to respond to my questions and I have subsequently had a second battery and EV charge point installed by Spirit Energy. Whilst there have been a few issues they have always worked through these with me and sent engineers back to change the sensor to ensure that the energy all goes to the desired locations. I am really pleased with my installation and the service I have received and would recommend (and have) Spirit Energy to anyone considering Solar power or related works. I am now in the envious position of having my energy provider paying me each year . .

I chose Spirit Energy for a solar installation at my son’s house in February, marking my third solar project after working with both national and local companies. Their service so impressed me that I immediately hired them again for a rental property. What sets Spirit Energy apart is their passion, attention to detail, and ability to exceed customer expectations. Archie, my main contact, maximised the roof space by using Jumbo Panels, ensuring greater solar coverage and a better return on investment. Rachel expertly managed the project, communicating clearly with tenants, agents, and myself to minimise any disruption. The install was efficient—thanks to doubling the roofing team, the job finished in under five hours. Electricians Klem and Will, who I had met during my son’s installation, handled the battery system with outstanding professionalism. Though I’m not local—Spirit Energy is Reading-based, while the installs were in Worcester—they delivered top-quality work that’s worth every penny. With Spirit Energy, it’s not just about cost; it’s about peace of mind and maximising value through expert installation.

Spirit Energy installed my solar power and Tesla Powerwall system in 2023 leaving a cable tail ready for an EV charger that might be required at some later date. I was impressed then by the exceptional standards of planning and communication together with the quality and professionalism of every aspect of the workmanship on site. Give this earlier experience I had no hesitation in asking Spirit to instal the Hypervolt charger now needed for a newly acquired EV. It is notable that even this relatively simple, straightforward task attracted the same high standards and attention to detail as the original main installation. To my mind Spirit Energy is a standout company, to be highly recommended.

After my Powerwall 2 failed due to a known issue, the Spirit team was supportive in arranging a warranty replacement as quickly as possible. The replacement (a PW3, which has an integrated inverter) opened the door to expanding our PV system so naturally it was a good opportunity to investigate possible options. The Spirit team were attentive and helpful in determining the best balance of cost vs return and quickly came up with a suitable design. I expected a reasonable wait for installation and was pleasantly surprised when they found a slot not long after agreeing the project - even then, the installation was performed much more quickly than anticipated, despite the terrible weather. Just like my experience with Spirit four years ago, the team did a great job, leaving a tidy site. They were great to chat with, answering any questions along the way and ensuring we fully understood the updates and changes made to our existing system. Its great to work with them, they uphold the same standards that won my business the first time around - highly recommended.

From the first contact to the completion of our installation, Spirit Energy have been thoroughly professional at every stage. Taking into account our personal preferences and our East/West facing property, they designed a bespoke solution tailored to maximise our system's performance. No plan can account for the type of weather we experienced during late December and early January, but throughout, Spirit Energy kept me updated with the revisions to the schedule and the installation team went above and beyond to get the system fitted. We would like to thank the whole team for their dedication, in particular: Nathan, Natasha, Ryan, Will, Simon and Chayce.

This is a company that really knows its business, applying technical knowledge and its organisational and installation experience to make my project successful. The whole process, from my initial enquiry through quotation and surveys, to obtaining approvals and to the very neat and tidy installation, was handled very efficiently with good communications maintained throughout. The comprehensive final handover and the instructive website impressed as well. It was a pleasure to work with such a thoroughly professional company.

Very useful advice over the phone when original installer not available. Excellent service much appreciated.

We were very impressed with the installation of our solar panels & batteries by Spirit Energy. From start to finish communication has been excellent. The scaffolding was put up just before the installation started and taken down again as soon as the roof work was completed. All the personnel from both the scaffolding firm and from Spirit Energy themselves were polite and friendly and the work was carried out with care. All packaging was removed at the end of each day and the site was left tidy. All in all one of the best experiences we have had with regard to work being carried out here.
