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 - Battery Installation
Customer Service

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.

High quality installation from Spirit Energy

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.

Thank you so much for such a detailed and thoughtful review — it really means a lot to the team. It's great to hear the system is working exactly as designed around your Octopus tariff and EV charging, and that the Powerwall has handled those grid outages without you even noticing. That's the system doing exactly what it should. We're really glad the Tesla UK recommendation led you to us and that you feel it was the right choice. We hope it keeps performing just as well for years to come!

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.

Tesla Powerwall 2
Customer Service

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.

Thank you so much for taking the time to leave such a detailed review, and for your loyalty over the years. It's brilliant to hear that our team made a strong first impression back in 2019, and that the quality of the installation held up well enough for you to come back to us in 2023. Two Powerwall 2s, a heat pump, and a backup gateway is a serious setup, and it sounds like it's doing exactly what it should. Your point about the intelligent charging behaviour in summer versus winter is spot on, and it's great to see a customer getting the full benefit of that. "Buy cheap, buy twice" sums it up better than we ever could. We'll be sharing that one with the team.
A Professional Job and Great Customer Service

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).

Thank you for such a thorough and considered review. It's great to hear the whole process, from first contact through to installation, hit the mark, and that you felt the value was there even knowing we are not the cheapest option. Those energy figures speak for themselves. Moving 93% of your consumption to off-peak and seeing bills like that in April is exactly the kind of outcome a well-integrated system should deliver. Thanks again for taking the time, and please do get in touch if there is anything we can help with down the line.

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.

Installation of solar panels - experience 4 years on
Customer Service

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.

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 . .

So Impressed First Time I Didn't Hesitate To Make A Repeat Purchase

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.

Smooth expansion of existing system

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 very first contact with Spirit's sales team, through to the system finally being handed over, the company has been a pleasure to work with. Within days of making first contact with the company, Archie, from Spirit's Technical Sales team came to our house to carry out an initial survey and suggest what kind of system would work best for us. The sales process was highly professional and included a detailed quote, including estimated cost savings we could expect to make and how long the system would take to pay for itself. The initial visit by Archie was followed up by a more detailed technical survey by Justin, Spirit's Head of Installations. Throughout the sales process, we always felt entirely confident that Spirit were experts in their field and were making the best possible recommendations. We ended up agreeing to buy a 40 panel system with two Tesla Powerwall 3s and a myenergi Zappi EV charger. The entire installation was overseen by Peace, Spirit's Project Manager. Without exception, everyone in the team who carried out the installation did a great job in quite difficult weather conditions and were a pleasure to have at our house. Now the system is live, it's very satisfying to see that even though we’re in the depths of autumn, the system is already producing and offsetting enough energy to make us almost fully independent of the grid.

Thank you so much for your wonderful review - we’re delighted to hear how pleased you are with your new 40-panel solar system, two Powerwall 3s, and Zappi. It was a pleasure working with you from the very first contact with Archie, through Justin’s detailed survey, to Peace overseeing the installation in challenging weather. We’re especially happy to know the system is already producing so well and making you almost fully grid-independent, even in autumn. Thank you for choosing Spirit Energy.

We had solar panels for several years before we added the Tesla PowerWall 2 battery fitted by Spirit Energy. What a difference that has made to our bills. We chose Spirit after interviewing several suppliers, because their thoroughness and depth of expertise really impressed us. The installation involved wiring through an outside wall into a very cramped understairs cupboard, which they managed perfectly. I'm writing this review five years later because we're in the process of selling our house and have been asked for copies of guarantees and electrical installation safety certificates. A quick chat with a friendly and helpful person at Spirit, and they were in my Inbox in minutes. What a reilef. Brilliant service!

I was drawn to Spirit Energy for our downsizing project in Cardiff by their excellent YouTube series on renewable energy. From our initial contact with Tok Charles, the whole project proceeded smoothly at the pace dictated by our builders (it took over 10 months); Spirit never pushed us for sales completion in any way. Our project manager, Natasha and both sets of installers (30 PV panels and later a Tesla Powerwall 3) were highly professional, helpful, and friendly. Spirit Energy is a joy to deal with, fair value for a top-flight service, and I recommend them to anyone seeking to install or upgrade their renewable energy system.

Excellent, very happy with the installation of Aiko panels with associated Enphase microinverters and a Tesla Powerwall 3. From the initial review and discussions with Nathan through to the survey by Justin and the installation by Ben, Jozef, Klem and Dan, managed by Peace, the work undertaken was of the expected high standard. Late customer changes were competently managed by Peace without affecting overall schedule. Some issues identified during commissioning were equally competently managed and resolved in a timely manner by Peace and Ryan. Another mention must go to the scaffolders. Blue Scaffolding, based in Reading, were efficient and courteous during the installation, paying attention to the restrictions defined during the survey. The subsequent removal of the scaffolding was completed on schedule. Such a difference to some other scaffolding companies we have experienced. Overall, we highly recommend Spirit Solar in terms of competitive pricing, attention to detail and work of a high quality.

Spirits website is jam packed full of detailed information, very useful as this was my first foray into Solar/Battery. After several phone calls to Tok it was time to get serious, he visited my home and produced a few proposals. At no time did i feel in the least bit pressurised, however I needed to be sure how the system was to be installed so an on-site survey was carried out by Justin for us both to agree the cabling to the Gateway & Battery. Competitors were only offering desktop surveys with actual locations of equipment and cable to be agreed on installation day which I did not feel happy about. The roofing team had the 18 panels installed on my roof in half a day and the electrics installed a couple of days later with the system commissioned on the same day. The guys were all very courteous and friendly with the standard of workmanship, as i had hoped - first rate. After commissioning a cosmetic issue became apparent with a few of the panels, Vishal worked with the manufacturer to resolve my concern and organised replacement of the panels in question before the scaffolding came down. I’m now really pleased with my system, half way into the month of March and am now generating more than 95% of my power needs from my Solar PV system despite my roof facing NE. I wanted to get this right first time so like me do your homework. For that you are going to need a company with a proven track record. Spirit Energy went above and beyond in helping me future proof my home.

Solar PV Panels + Home Battery Installation by Spirit Energy
Just had a PV and Home Battery installation made at my mother’s property in Hartley Wintney using Spirit Energy. Extremely impressed with the handling of this mini project from start to finish. First called Spirit Energy after watching a few of their YouTube videos online then realised they are located fairly locally. Mark popped round to evaluate the property and was very professional and knowledgeable in his field, which in turn gave us the confidence to go ahead with the project with Spirit. The comms were great throughout the install from the setup of the scaffolding, installation of PV panels and finally install + commissioning of the home battery. Install was finished last week and we are already seeing the cost saving benefits! Would recommend Spirit Energy to anyone looking to get a PV and/or Home Battery installed. Thanks again all.

We had Spirit Energy install a 5kW SolarEdge PV system in January 2024 and I have to say what a totally outstanding job they did for us. We chose them because they were a local Reading company and were recommended. All of the staff have been polite, friendly & professional, right from our first contact with Vishal who helped in getting permission from SSE and dealing with them, to Megan for processing the order and then Natasha who was our project manager who kept us updated about all that was going on and finally hats off to Matt, Sam, Ari & Yozsef who installed the system in absolutely bitter conditions. Their work was neat, tidy & they kept us informed about everything they were doing and asked about our preferences and made suggestions giving us total confidence. We cannot wait to see the savings from this system and we will soon add to this with a battery. We cannot recommend Spirit Energy enough so if you are thinking of getting renewables then you won't go far wrong choosing them. Total 5⭐ service from start to finish.

I am very happy with the solar panels and battery installation, and how impressed I was by the hard work that was put in by the 4 engineers. They did a brilliant job in some very difficult weather. There were some unforecast heavy showers, but they worked through them. They pulled out all the stops, and went the extra mile to get the work completed in a single day. I shall not hesitate to recommend Spirit Energy to my friends and neighbours that are looking to install in the near future.

Earlier this year Spirit Energy installed a (supplementary) battery in my house to enhance my utilisation of solar energy. The process was quick and easy, the price competitive, and the new battery was installed quickly, once the grid permission had come through. It took less than a day to fit. The fitter, who was courteous, helpful and efficient, left things neat and tidy and also took time to describe operation of the battery, once it had been installed. He really knew his job. With the battery, power cuts are barely noticeable (eg. just a flicker from the lights). Past experience with this company has been equally good. 5 years previously they installed my PV solar generation system, then a couple of years later, my first battery. They do a good job using good quality equipment and my whole system has worked faultlessly since installation. As predicted, my power consumption reduced substantially following PV and battery installation, particularly during the summer. I have no hesitation in recommending this company; I have found it one to be relied upon.

Spirit Energy have just finished fitting 24 PV solar panels & Tesla Powerwall 2 battery at my property. The whole process from the beginning to the completion was great! Starting with wise sales engineer Sam, superb project manager, Natasha, effective surveyor Justin, fast & careful scaffolders, hard working diligent roofers & finally The great, neat & precise electrical installers who tied up all ends & made the system work perfectly well ! And also customer support Ryan & Charles from accountancy - everyone had their part in successful delivery of this project. In time, without substitutes & in budget ! My PV panels are facing East (12) & West (12) covering the whole roof, and now in summer BOTH sides manage to produce equal amount of electricity even from ambient sky at 5.30am, thus before East side gets lit directly with sun! And this output at 5.30 am is sufficient to power my whole house needs at that time! So, East & West orientations work well too! Thank you everyone.

I had a solar panel and electrical installation done by Spirit to fit alongside an existing battery installation. The experience was excellent. Spirit conducted careful pre-install checks and surveys, which eliminated any surprises. They completed the installation as promised. However, there was a minor issue with pipework in the roof that wasn't identified in the survey. But, they presented a simple alternative solution that didn't hinder the installation process.

My installation consists of 28 PV Solar panels. divided equally between E and W facing roofs together with a Tesla Powerwall-2 battery and an EV point in the garage. Having researched a number of possibilities I opted for Spirit because they seemed to have a genuine interest in providing the most appropriate system at a sensible price. Once the contract was signed a project manager was appointed and thereafter everything appeared on date and on time. On-site workmanship was exemplary with all installation and wiring extremely neat and professional. The various teams involved were all very courteous, polite and helpful - and clearly highly competent. A wealth of technical detail and general information and advice is available on the website, and the staff are willing to help and advise on individual situations.

Spirit Energy installed solar panels, battery and inverter for our property. The whole process was seamless. We explained what we required and, after an initial estimate, we had a preliminary visit to discuss in detail, a survey followed by a full quotation. The installation, from scaffold erection to completion was stress-free and very professional. Spirit Energy kept us fully informed throughout and the handover couldn't have been easier. Although not the cheapest quoted we received, we consider the extra paid to have been well worth it in both term of quality and peace of mind.
