NRG SOLAR LTD

⭐⭐⭐⭐⭐ Really pleased we chose NRG Solar for our solar panels and battery installation. From the first enquiry through to the installation, Rob and the team were friendly, knowledgeable and easy to deal with. There was no hard sell – just honest advice and clear explanations, which gave us confidence we were making the right decision. The installation was completed professionally, everything was left clean and tidy, and the team were happy to answer all our questions. What impressed us most was the support afterwards. Rob took the time to help us set up the app, optimise the battery settings and make sure everything was running as efficiently as possible. It’s great to find a company that genuinely cares about its customers even after the installation is complete. Excellent communication, fantastic service and a high-quality job. We wouldn’t hesitate to recommend NRG Solar to anyone thinking about installing solar panels or battery storage.

Very pleased, would definitely recommend. I approached NRG solar because unlike some companies they send someone out to assess the roof etc ( I tried a few others and they want the customer to take lots of photos inside and outside before anyone will even come out - OK for a standard build with standard access). I spoke with Craig, told him everything about the access issues, he came out in person. He quoted for a system solar and battery which was 20% cheaper than any the system I had been quoted through the company recommended by Octopus ( who wouldn't come out to assess!) Next step, confirmation that your solar can connect to the grid ( to sell your excess electricity). Took about 6 weeks. The installation crew arrived on site, it was all fitted up and running in one day. About 7 - 10 days later I received the pack with MSC cert etc, in order to contact Octopus switch tariffs, very straightforward. Very pleased with NRG Solar Ltd, it is a company which is happy for you to contact them with any queries, they will work around any access issues, and get the job done!!!

Contacted NRG Solar through email first, within minutes they had replied. Arranged a visual phone call meeting with Craig together with my wife over the phone for a few days later. They already had a picture of my home roof at my postcode address, which I confirmed was correct. He had already sorted out different Solar options, which he then carefully explained to us both. We agreed the best option for our needs. Couple days later Rob came round to the house for a site visit and confirmed where everything would be put and the stages of instalment. He then looking at our roof ridge tiles (age & condition) suggested about having a Dry ridge replacement done, which I agreed on. Scaffolding put up on day agreed, the NRG fitting crew guys where brilliant they fitted the 16 panels, 1 inverter and 2 batteries on the two hottest days of the year. Not complaining once. Whole installation completed over three days and working. A big thank you to Alan, who talked me through the navigation of the system and also helped me out with other issues as I'm not the best at technical things over the phone. The ladies also in the office where quick and efficient with all documentation & paperwork. From initial contact to finish of work everything went smoothly, Glad we chose NRG Solar to do our full installation.

Great experience and the system is already outperforming predictions! I had our system installed by NRG Solar just over a month ago a 16 panel setup (11 west-facing, 5 south-facing) paired with a Sigenergy 20kW battery storage system. A special mention has to go to Rob, Alan, Sam, and Claire, to name just a few of the brilliant team. From initial contact through to the actual installation, they were professional, polite and kept me updated post install prior to export connection. We are already seeing fantastic results. For May and June, our predicted generation was around 31 kWh per day, but the solar has actually been producing an average of 33 kWh per day. It’s brilliant to see the system beat expectations so early on. Highly recommend NRG Solar to anyone.

If you’re looking for a local honest company to install a solar and battery storage system in Warrington then Rob and the team at NRG are a great choice. We needed a new roof so took the opportunity to put in-roof solar panels at the same time. It’s a much neater job than on-roof systems as the panels are nearly flush with the roof. We made savings combining the two projects into one. NRG have been very professional during the project with great communication throughout. Where there were some minor issues ( as does happen on these projects) Rob was understanding and rectified without any fuss. Throughout the project Rob kept checking in with us to ensure we were happy with how the works were progressing. We installed 15 Aiko panels along with a 20kW Sigenergy battery and inverter. Overall a very professional re-roof project and now I’m transfixed with how much money I’m saving and earning every day feeding back to the grid!

Great expereiance from Rob and his team 2 roofers and 2 electricians arrived, every thing went smooth and all sorted in a day. Would recommend..

Had a Tesla system fitted. No issues with installers or scaffolding etc. Had 1 battery not working through no fault of the installer. Rob ordered a new battery and kept me informed by email. Changed the faulty battery quickly. Can't fault the quick progress and regular communication and didnt pay fully until system was commissioned and working. Would definitely recommend

Thank you so much for the donations of the solar panels really appreciate it you went above an be hound to help. Thank you 😊🙏

I recently had NRG install my solar panels, inverter and batteries along with some roof repairs while they were up there, while not everything went to plan and there were a few hiccups along the way , however I would recommend Rob and the team and I would use them again. Rob was excellent — competitive pricing, thoughtful design discussions, and a very good install lead time. I opted for 10 panels 5 SW & 5 NE facing , a 6KW Hanchu inverter and 2 x 9.4KW Hanchu batteries As with most installs, not everything went perfectly. The scaffolders arrived late without enough scaffolding for the 2 rises, but Rob jumped on it sorted for the following day. The roofer was amazing and coped with bad weather and doing some roof work and panels in less-than-ideal conditions. The electricians had some issues with the kit and this resulted in Rob coming down himself and arranging to swap the inverter , there were some other issues around random tripping and Hanchu themselves came out and this was resolved with a combination of some system settings and a different RCBO Im about a month in and the system is doing exactly what I expected and better than the design spec – so I’m really happy Alan has been amazing with helping get the export set up and setting up the app and getting the best from the system I’m saving money on my bills at a higher than expected rate and ill be looking for my third 9kw battery early next year Overall, I’d describe NRG Solar and Rob as a small, competitive company that genuinely cares. Communication with Rob is good, even at weekends, and issues get resolved quickly and the support from Alan is just amazing, based on my experience, I wouldn’t hesitate to use them again.

From the start Rob was expertly professional and took the time to explain the different options and how the system would work for our needs. We’ve had a fantastic experience with the whole NRG Solar team. Dave and Craig on the roof, Charlie and Chez on the electrics, Claire and Sam handling operations and handover have all been brilliant throughout: professional, knowledgeable and genuinely helpful. A special mention also has to go to Alan, whose ongoing expertise and support have been exceptional. He is incredibly responsive to any questions we have about the system and is clearly passionate about ensuring it is optimised to its full potential. Our system includes 5.1kW Aiko panels, a 6.1kW system size, 30kWh Sigenergy battery storage and a 6kW inverter. Since going live we’ve only used 1.21kWh from the grid, and we’re already ahead of predicted savings for April despite export not even being live yet. The whole process has felt well organised and the workmanship has been excellent. Would highly recommend Rob and the NRG Solar team.

I've just had a recent installation with NRG Solar, from the start Robs communication and expertise was brilliant. At the sales stage with Rob was excellent — competitive pricing, thoughtful design discussions, and a in depth explanation of how solar works and how you make it work for you. I really happy with the finished product it is generating and keeping us off grid better than expected. We had Dave and Craig on the roof and Charlie and Chez on the Electrics, Claire and Sam on the operations and handover. We have 12nr 510kw Aiko panels,system size is 6.1kw with 30kw Sigenergy battery storage and a 6kw inverter. We are already ahead of predicted savings for April it’s not been a full month and our export isn’t even live yet. Another point to note with NRG is their aftercare and monitoring. Rob employees Alan who is a battery specialist who will monitor and educate you on how best to use your system. He knows the ins and outs of the app gives you training and guidance on how to set everything up.

Rob and the team at NRG solar did a fantastic Job with my solar experience, from start to finish they were great, I had numerous quotes off other companies and they gave me the best value and price I could find not to mention Robs knowledge of the solar industry put my mind at ease when he came to see me. Highly reccomend the team at NRG solar.

I originally contacted several solar companies, none came back with concrete proposals. Like a lot of people, i am a solar newbie.I was about to give up, then saw NRG on Facebook. I spoke with Rob,( on a Saturday) explained what I wanted, as many solar panels that could be fitted, the correct inverter, and enough storage . Within a few days he came back with a proposal and price. Within a fortnight he delivered exactly what we had discussed. The scaffolders were polite and quick, both to put it up and take it down, the fitters likewise. As a welcome bonus his expert on Solar, Alan turned out to be an absolute oracle, setting the system up remotely and as he said, always available to answer any questions. (5 stars) As a whole a great job, efficient installation highly recommended .Thanks to Rob ,Alan and all the team.

Rob and the team perfect to deal with, from first meeting at my house install and up and running within 2 weeks, 3 days on site including scaffold up and down, first couple of days up and running completely off grid and selling back. Thanks

I've just had a recent installation with NRG Solar, from the start Robs communication and expertise were excellent. We've had 22 panels fitted front, back and on a detached garage. I've had a 20kwh solax battery and 6kw solax IES inverter. All the guys who came where very respectful and professional. I really happy with the finished product it is generating and keeping me off grid better than expected. Another point to note with NRG is their aftercare and monitoring. Rob employees Alan who is a battery specialist who will monitor and educate you on how best to use your system. He knows the ins and outs of the app gives you training and guidance on how to set everything up. My brother has had solar fitted with a well known energy firm and his experience has been much worse than mine.

We’d been thinking about solar for a couple of years. After looking at rough costs online to see if it made financial sense, I was immediately bombarded with calls from different companies. Either the timing wasn’t right or I just didn’t get the right feel from who I spoke to. Then social media did what it does and started filling my feed with solar ads. I ignored most of them, but one caught my eye: “Guess how much these solar panels are going to save this customer in its first year alone.” I messaged NRG Solar and Rob called to see if he could pop round. I’ll be honest — I was hesitant. I’ve previously had a bad experience with a salesman (for something else) who wouldn’t leave without a signature. Rob reassured me that wasn’t their approach. He came round, had a quick look outside, spent maybe half an hour inside reviewing our usage, answered all my questions (there were plenty), gave us a price and left. No pressure, no awkward hovering, no “what do we need to do to get this signed today?” Just straight facts and solid advice. I already had a rough idea of ballpark costs from my own research, but Rob’s zero-pressure, honest approach made the decision easy. We didn’t even bother contacting anyone else. There was a bit of a gap before we went ahead — new baby, Christmas, general life chaos — but the communication stayed open (mainly me messaging Rob, not the other way round). Install day came and Dave (panels) and Chris (electrics) were both spot on. Polite, tidy and just got on with it. We had a couple of tweaks mid-install, particularly around cable routing, but Rob was available straight away to talk it through and make sure it was sorted. Everything was cleaned up and the scaffolding was gone the next day. What’s really stood out though is the aftercare. Rob mentioned they had a dedicated support guy — Alan (definitely their secret weapon). Since going live (3rd Feb), I’ve spoken to Rob or Alan pretty much every day. That might sound over the top, but getting the system optimised properly has been reassuring. If something looked slightly off, Alan was straight on it — even tweaking settings at 3am to make sure we’re running efficiently. Genuinely the best aftercare I’ve had after making a purchase. Even in February with poor weather, we’re already on track to be at around half our normal electricity spend, which is impressive this time of year, and we don’t have our export account set up yet……

I used NRG as they were local to me, Rob came out and explained everything in detail, we walked through the quote, options, mounting etc. DNO approval was submitted and chased in good time, install day was smooth and asked them to fix ridge tiles while scaffolding up. Sigenergy app was setup and working with ease. Rob then sorted export approval with DNO. Guys cleaned up after themselves and took all rubbish. Excellent service A1+

I wanted to share an honest account of my experience as a customer of NRG Solar, because my installation wasn’t straightforward and the way the team handled it really mattered. The sales stage with Rob was excellent — competitive pricing, thoughtful design discussions, and a very quick install lead time. My setup wasn’t simple either: I already had a 4 kW system from 2012 with a 3.68 kW inverter and FiT payments attached. The new project involved replacing and expanding the array to 8.37 kW, upgrading to a 6 kW inverter, adding three 9.4 kWh batteries, and keeping everything FiT‑compliant. As with most installs, not everything went perfectly. The scaffolders arrived on the wrong day when I wasn’t home, but Rob jumped on it immediately and had it rearranged within two days. The roofers often arrived later than planned, which made my own scheduling tricky, but again Rob stayed on top of it throughout. Craig, the electrician, was outstanding. His workmanship is extremely high quality, and he even redesigned the setup around my Zappi EV charger so the new batteries wouldn’t discharge into it. Around 2.5 months later, we’re still working through some FiT complexities because the generation meter was counting battery charge and discharge. Rob and his team have been fully engaged with multiple suppliers (Infinity Innovations, Hanchu, etc.) to get this resolved. The back-office team is clearly learning the nuances of more complex systems, and although there were a few MCS certificate errors along the way, Rob consistently stepped in and got everything corrected. As of today, everything has been sorted — including adding another 9.4 kWh battery so I’m ready for a future inverter upgrade to 10 or 12 kW when they’re released. Overall, I’d describe NRG Solar and Rob as a small but highly competitive company that genuinely cares. Communication with Rob is seamless at any time of day, including weekends, and issues get resolved quickly. It’s clear he’s investing in training his team so they can handle more advanced designs without mistakes. They don’t shy away from complex challenges, and based on my experience, I wouldn’t hesitate to use them again.

I highly recommend NRG Solar LTD. From the very start, Rob (the owner) was friendly, knowledgeable, and completely transparent. He provided a very competitive price and clearly broke down the costs for panels, inverter, and installation — something no other quote I received did. There was no pushy sales at any stage, just honest advice, and Rob was always at the end of the phone if I needed him. The installation was excellent. Scaffolding was only up for the minimum time, and both the roofer and electrician were very professional, respectful of my property, and clearly knew what they were doing. I was kept fully informed throughout the process, and the quality of workmanship is top-notch. The solar panel system is performing exactly as detailed in the quote. The aftercare service really sets NRG Solar apart — you get a dedicated expert to monitor your system, help fine-tune the setup, and ensure you’re using the correct solar tariffs at the right times of day. This support lasts for two years, which is invaluable as you learn how your system performs across different seasons. Another big plus is that there are no upfront costs at all — you only pay on completion, once you’re fully satisfied. Overall, an excellent experience from start to finish. Highly recommend NRG Solar LTD.

I had my solar system installed by NRG SOLAR Ltd and I’m very happy with the work. The team was professional and polite — two electricians and two roofers did an excellent job. Everything was installed neatly and works perfectly. Rob Cook, their manager, was very helpful and kept me informed during the whole process. I definitely recommend NRG SOLAR for anyone looking for a reliable and professional solar installation.

Rob and his team were all fantastic lovely lads, very polite, they did a fantastic job, no fuss, no mess and looks great, After sales service is also fantastic Rob is always on the end of the phone and can answer all of my questions, It was a pleasure to use this company, I would highly recommend them and I would definitely use them again

Neat install. Very competitive price. Quick turnaround from visit to completion in 1week, including scaffolding going up and down. Electricians were great and even fixed a few issues with my consumer unit, as they installed the kit. They broke a couple of tiles, but no issue, as these were replaced. Cleaned up all packaging and rubbish at end of job. Rob kept me regularly updated on plans and progress. See pics attached.

⭐️⭐️⭐️⭐️⭐️ We’ve partnered with NRG Solar on projects and found their team to be reliable, professional, and great to work alongside. Their solar installations are carried out to a high standard, and the communication on-site makes coordination smooth and efficient. A solid company that we’re more than happy to recommend.

Recently had NRG Solar in to fit 20 panels, inverter and 3x 5.8kWh batteries.Oh and a Zappi car charger. Rob did a great job of the proposal, quote and all the comms and the follow up paperwork. The guys did a good job fitting everything professionally and neatly. The long warranties and full customer satisfaction guarantees before payment gave me extra confidence in the installation. Great system up and running - I’ve only used pennies worth of electric since the fitted last week and I run a plug-in hybrid too. Looking forward to making more savings once I can sell back to the grid when the grid application is through (DNO) - when I should be able to make £1-2 per day in surplus electric ! I would happily recommend Rob and the team at NRG. System should pay back in less than 5 yrs.

We recently had solar panels and battery storage installed by NRG Solar. The whole experience has been very smooth and stress free, largely due to the excellent communications from Rob. From placing the order, the works were complete a week later, with the actual installation being completed in a single day, and only the erection and removal of the scaffolding sitting outside of this. The system is working perfectly, and we've gone from spending £200/mo on electricity to currently making a nett income (or at least we will be once Scottish Power do their bit and allow us to export to the grid). Highly recommended.
