Reviewers describe Synergy PV Renewables Ltd as professional and knowledgeable, with several saying they were given clear advice without a hard sell. They report installations of solar panels, batteries and EV chargers that were left clean and tidy and done in the time stated. Post-installation handovers and aftercare support are also praised, and some reviewers say they saw energy savings. One reviewer reported that a plumbing joint was knocked during work, causing a bedroom ceiling leak, which the firm then repaired and repainted the same day.
From 1st meeting to handover everything went smoothly and to plan. Reece and Alex gave great advice and 3 options for us to have a look at. It really felt as if they were trying to get the best system for us and not just pushing the most expensive one. The installation itself was seamless and we kept completely operational during the process. The installers were polite and hardworking and the works were completed within the days allowed. Since it has been operational we have been very impressed with the results. Being able to track savings on an app which is so useful and gives you comfort that Solar was a great idea. Reece and Alex also revisited to hand over and show us the basics and how to navigate the app. All in all 5 star service from start to finish. Craig McMahon Focus Rigging & Scaffolding Ltd
Great, caring and very professional company. They came to my flat to ensure that it was energy efficient and did an amazing job. Alex, Adam and Chris are polite and professional and thorough. Highly recommend this company. 🙌
Highly recommend. Great communication, quick install, the layout changed as the install progressed, our choice, but the company worked with us to make the changes. Very pleased with the finish
From the initial meeting I knew these guys knew their stuff. Their professionalism is second to none. Alex provided me with a system proposal that filled me with great hope right from the start. Every level of detail was considered and no stone un turned. The installation process was swift and successful and all of his team are lovely polite blokes. But most important is the success of the performance of the system. It has gone above and beyond and exceeded my expectations. I can now safely say that I no longer pay for my electricity and my family and I use a lot. We are also fully protected against any future energy hikes. It was a fantastic investment and I could not be happier. You will not find a better, more professional , more reliable team. Thank you synergy !!!
Synergy installed 33 integrated solar panels, a battery system, and inverter on my new-build home. From the initial consultation through to completion, they were fantastic. Everything was explained clearly, they were always on time, and they kept the site clean and tidy throughout the job. As someone who runs a plumbing company, I have high expectations when it comes to tradespeople, and Synergy exceeded them. Their professionalism, quality of work, and communication were first-class. I wouldn’t hesitate to recommend them to anyone looking for a solar installation. Great job from start to finish. ⭐⭐⭐⭐⭐
We had solar fitted at our office. The entire process was smooth and efficient. Highly recommended
We recently had solar panels, a battery system, and an EV charger installed by this company and I couldn’t be happier with the whole experience. From the very start they were professional, helpful, and kept us informed throughout the process. The installation work was brilliant — everything was completed neatly and tidily, and the team clearly took pride in their work. Communication was excellent at every stage, so we always knew what was happening and when. The aftercare has also been fantastic. They took the time to go over everything properly once the install was complete and helped us get set up and working smoothly. Really pleased with the whole experience and would happily recommend them to anyone considering solar, battery storage, or an EV charger installation.
We looked at installing solar panels for both our home and business and carried out extensive research before choosing Synergy. From the initial survey through to installation, the team were professional, knowledgeable, and completely reliable throughout the entire process. They explained everything clearly, including panel performance, battery storage, and projected savings, without any pressure or hard sell. The installation was completed efficiently and to a very high standard, with excellent communication throughout. The pricing was very reasonable and the system has performed brilliantly since installation. A first class company delivering first class service from start to finish.
Contacted Synergy to discuss solar and electric vehicle charging solutions. They were great offering genuine advice and advising to wait until our re-roof is completed before adding solar panels (the roof is very old and has very brittle old tiles). They clearly put their customers first and give advice thats right for them instead of just pressurising to get the sale. They completed the install of the EV charger and were on time and efficient and their pricing was competative. Cant wait to get them back in for our solar syetem when the time is right. Would highly recommend these guys - decent honest company 👌
My journey into solar began in December 2025. I ultimately installed a system with a Tesla Powerwall 3 and expansion battery, 14 Aiko 515W panels, and a car charger—tailored to suit my fully electric home. With annual consumption of around 14,000 kWh, my energy bills were significant—£500–£600 per month in winter and around £130 in summer. Given the scale of my usage, solar felt like the most logical solution to reduce these costs. However, navigating the solar market was overwhelming. There are countless companies offering different systems, often pushing specific products or outsourcing installations to the lowest bidder. This pattern continued until a friend recommended Synergy, having recently used them. From my very first call with Alex, I noticed a clear difference. His approach was professional, consultative, and genuinely customer-focused—unlike my previous experiences. He visited my home in person to carry out a detailed survey, taking the time to understand my property, which has multiple roof orientations, and my specific energy needs. What really stood out was the level of care and attention. Alex visited my property four times before the installation even began. He also carried out an in-depth assessment of my energy usage to identify where I could improve efficiency and maximise the benefits of the solar system. This went far beyond my expectations and gave me confidence that I wasn’t dealing with a “conveyor-belt” company, but one that truly tailors solutions to the customer. I received several quotes from both large and small companies, but many seemed focused on pushing affiliated brands or offering generic solutions. Solar is not a one-size-fits-all investment—it requires careful planning to ensure long-term value. I wasn’t looking for the cheapest option; I wanted the best solution at a competitive price. Synergy delivered exactly that. My system was installed at the end of March over a period of two days, and the entire experience was excellent. Alex, Reece, and the wider team—including scaffolders, roofers, and electricians—were professional, efficient, and hardworking. They kept everything tidy and ensured the installation ran smoothly from start to finish. Another key factor for me was the peace of mind they provide. Synergy includes strong aftercare support, along with fully certified installations and insurance-backed workmanship warranties, which reassured me that the system is protected long-term. If you’re considering solar, I would highly recommend Synergy. They offer a genuinely customer-centric approach and clearly take pride in delivering high-quality, tailored installations.
We live in a semi-rural location and have an unreliable grid supply. So we decided to install battery backup and came across Synergy PV Renewables. Their reviews are very good so we contacted them, and Alex came to see us. We already have solar panels and a very old wet cell battery backup, so we discussed all the various options, including a replacement battery backup. Alex is very knowledgeable, but not at all pushy. He explained everything in a language we understood, and we decided on a Sigenergy Sigenstor 10kWh battery. Currently one of the best systems on the market. The Sigenergy app is really good too allowing you to watch your usage in real-time. A special thanks to Reece and Zach who completed the installation in one day. All works were completed to our satisfaction with very neat cable runs. We would not hesitate in recommending Alex and his team at Synergy PV Renewables. Thanks guys
Worked with Alex on 3 projects now and he’s always very professional and the workmanship is spot on. Can’t recommend him and his team enough.
We had Synergy Renewables install a 38-panel solar system on our small commercial office unit and the whole process was smooth from start to finish. The install was clean, tidy, and completely seamless in a working office environment. Alex made the return on investment very clear from day one, and after seeing the first and second month’s energy bills, it’s clearly on track — if not better — than predicted. A very solid business investment and a company I’d happily recommend
Loved working with Alex and team, they are so knowledgeable and helpful. Installation of our solar panels was perfect, quick and tidy. Would highly recommend. Thank you.
We recently had Synergy PV Renewables installing 12 panels to our rear-facing roof. When working in the roof, the guys managed to knock a plumbing joint, which unfortunately caused a leak through the bedroom ceiling. Accidents happen, but what really impressed us was how quickly and professionally the team dealt with it. Within hours, a building team arrived, repaired the plumbing, patched and repainted the ceiling, and made everything good again — all in the same day. They even came back the next day to apply a second coat of paint to make it perfect. What could have been a disaster was turned around brilliantly thanks to their honesty, speed, and workmanship. You really see a company’s true quality in how they handle problems, and Synergy PV Renewables proved themselves first-class.
Alex, Reece and the team were excellent in handling the integration of our multiple energy systems changes (battery, solar, old solar integration, ASHP integration, house system and main fuse upgrades). Faultless and fun!
Alex and Reece did a top quality job for us. Installed solar panels and battery after careful and professional consultation taking into account our budget, our requirements and what best suited the site. Thoroughly recommended.
My Off-Grid Garage Setup Alex installed 12 solar panels on my garage roof so that I can mainly supply back to the grid eventually , for now 3 panels keep things running off-grid until network power get my supply connected .honestly, I’m impressed, not only with the system but with Alex’s team and his knowledge and workmanship, the 3 panels run the lights, internet alarm system, security cameras, garage door and let me charge my tools without any issues. Looking forward to Alex and his team coming back to finish the installation once I’m connected to the grid.
From installation to service, they were excellent. They staged the installation of the solar panels to help complete the roof work, and later returned to install the inverter and batteries.
Speaking to a company that actually answers the questions so you understand is so refreshing. The work done to install an EV charger and Sauna power was kept to the quotation was on time and neat. Alex and Reece are polite well spoken presentable and trust worthy in an industry that is often full of cowboys and unqualified workers causing problems. Genuinely can’t recommend enough for an electric one stop shop company.
Reece and his team fitted a solar system to my mum’s house. I am very impressed with the efficiency of the team and the high standard of finish especially given the tricky cable runs. Thanks guys will definitely recommend Bradley
I contacted Alex over the phone and unlike the national providers who I spoke to, he actually offered to come and see me to explain how he would go about implementing solar panels for me. He sent a drone up to survey the roof and discussed in detail how the electrics would be routed through the house. On the day the electricians who did the work confirmed what had been agreed (they had been well briefed) and delivered exactly what had been promised. In my opinion it was a premium service (everything was completed in 1 day) and I have never encountered scaffolders with a more impressive can do attitude, everything came through a single kitchen window and arrived and departed on days when I didn’t have my children (I’m a single parent). I would definitely have paid a premium for this service but whether it was due to doing the survey in person or just being more local than the national providers who quoted they were the lowest quotation as well. I would recommend Alex and his Synergy team, in fact I already have.
The professionalism was 5 stars great team.
We are very satisfied with the installation of our EV charger. The service was very prompt from the survey to the completion of the installation. We would certainly recommend anyone to use them.
Fast response and a timely cost effective fix. Many thanks
I can't recommend Alex and Synergy Renewables enough!! I filled out a form online and got bombarded with calls from 5 other companies. Some came round to look at the job, others claimed they could give me a quote without coming to look at the job. I was definitely not going to trust a company who wouldn't even check if my roof was suitable. Alex personally came to see me 3 times (we had a lot of questions!!) He was great in explaining it all to us, he even installed temporary monitoring to analyse our energy use. They weren't the cheapest option but were well priced. My house now feels like a micro power plant generating energy for years to come. A huge thank you to Alex and the team at Synergy!!!
Synergy installed a stand-alone battery system and Zappi smart EV charger to work alongside my existing solar setup on an old Feed-in tariff Now, I never waste electricity back to the grid any excess solar power goes into my battery, heats my water, or charges my car. Very happy with their service and costs for the work, Thank you Synergy!
Synergy Renewables installed a 4kW Solar System and Battery for me last month and I can’t recommend it or them highly enough! I won’t lie this is definitely not my area of expertise but the team were so knowledgable and really went above and beyond to guide me through the whole process - they even helped me review my energy provider tariff so I’m now on a smart tariff that means charging my battery overnight is done at the absolute lowest rate. I also love the Fox app that comes as part of the system because it makes tracking my electricity usage so simple and has been another great way for me to keep costs down. If you’ve been toying with the idea of switching to solar give these guys a shout, you won’t regret it.
Excellent People & Truly know what they are doing. 100% Recommended. Luke Denham - Owner of Commercial Workspace Consultants Ltd
"Synergy PV Renewables installed 562 solar panels at our factory in February last year. Over the past 10 months, we’ve saved more than £30,000 on our energy costs. The team was highly professional, managing the project seamlessly from start to finish. Their bi-annual cleaning and maintenance service has ensured the system operates at peak performance, giving us complete peace of mind. We couldn’t be happier with the results and would highly recommend Synergy PV Renewables to any business considering solar energy." Wenzel's The Bakers
Would highly recommend Synergy. On a personal quest to reduce and monitor our electrical usage we contacted Synergy who designed and built a small PV system to capitalise on our limited space/budget and north facing roof complexity. Were others said it was not viable synergy worked a solution. With little PV space available we were able to install a 4 panel system with 4kw battery capacity to capitalise on off peak energy rates to offset higher day dates. We currently use on average 12-16kw of electric a day and our system albeit smaller than normal installs you see popping up and installed in the autumn has lowered our current electrical bills from circa £110 a month to just under £70, this saving has been mainly formed from off peak purchases of electricity which the battery feeds back into the house during normal times. With our PV north facing our “good months” are unfortunately the height of spring/summer/autumn but with 1800w of generating capacity our system should generate an additional 3/5kw a day lowering our electrical costs below £45/50 a month, not bad for a 3 bed!! Due to some good solar days for winter (around a kw generated) and balancing negative energy prices via charging and discharging we’ve manage to have 2 days were our cost for electricity for the day was negative which was happy occurrence! Once again, I would highly recommend Alex/Grant and the team on your renewable quest!!
Excellent service from start to finish. The team were very helpful and knowledgable. We are really pleased with our solar PV system and noticed straight away our energy bills getting cheaper. Highly recommend Synergy PV Renewables.
What a great bunch of guys, so impressed with their workmanship and professionalism. Going forward would always recommend to family and friends
The solar panel installation and maintenance industry is riddled with companies who just are not up to the job. Synergy PV Renewables Ltd restored our faith that there are good guys out there who know their industry, provide an excellent service and value customer care. I cannot speak highly enough of the job they did for us - erecting scaffolding, lifting 15 panels evicting pigeons, cleaning the roof and panels putting back the panels, making the whole area bird proof, and checking all in working order as there were some issues with our inverter, oh and they threw in a free gutter clean too! Would highly recommend this company.
Alex did a great job installing our home battery storage and EV charger. All cables neatly boxed away, everything working perfectly. Highly recommended!
Cant rate them highly enough! Alex obviously knows what he's talking about, his years of experience were apparent from our first conversations. His team of electricians and roofers were great- friendly, hard-working and thorough. They all did a fantastic job on our PV system, it looks like a work of art too! A proper job with all the certificates and documentations contained in a comprehensive handover pack. Highly recommended!
Fabulous work from the Synergy team. They were quick to quote, gave a good price and booked us in swiftly. Very impressed from start to finish. Would have no problem recommending them to family and friends or using them for future projects.
Theses guys were really good, Alex surveyed the site, gave some sound advice and a really competitive price. The install was clean and quick and the guys were very accommodating to my wants and needs, they explained everything well and we are currently 6 months in and saving more than expected, happy days. Would recommend for sure, Andy.
Synergy Renewables have done a superb job for us. They have gone above and beyond to make sure all our energy sources are working as we would like and have helped us fully understand all the complexities. We would highly recommend them and are very grateful for all their work, their helpfulness and their high attention to detail and thoroughness.
