  The initial install was great and scored 5 stars originally however the subsequent expansion installation not so as this review is for and have had to chase for rectification and no standard paperwork received to date despite chasing and several promises and 3.5months passing from installation. *update* paperwork has been received and an apology due to some delays with the DNO & some staff absences; having had a discussion with them I’ve accepted the issues but explained some communication would have been better and whilst we are still awaiting the revision from the DNO following the upgrade all the other paperwork has been received and communication ongoing over the delay and a goodwill gesture has been offered and accepted. As I said originally and above they have been great to deal with initially and hopefully the small blip in the road will smooth out for them now and genuinely happy with the installations themselves

  We had an outstanding experience with FEC Renewables Ltd. Although they’re based in Rotherham, they came out to assess and install our system at our home near Newark-on-Trent, and the entire process was seamless from start to finish. Mark Alexander in sales provided clear, comprehensive explanations right from the beginning, taking the time to ensure we fully understood the system and our options. The whole project was then carefully planned and organised by the owner, Oliver French, who was equally personable and generous with his time and advice. Our installation involved a fair amount of paperwork, including obtaining a DNO certificate, but Jackie and Elise were always available to explain each stage and kept us fully informed as everything progressed. Nothing ever felt rushed, and any questions we had were answered promptly and clearly. Overall, this is a very impressive and cohesive team who clearly take pride in both their workmanship and their customer service. We wouldn’t hesitate to recommend FEC Renewables Ltd to anyone considering solar installation. For our system, we chose the EcoFlow Power Ocean setup with two 5 kW batteries, a 6 kW inverter, and 22 × 455 W panels. Oliver managed to fit two additional panels for us, bringing the total system size to approximately 11 kW. We understand the inverter can handle up to 13 kW, and the batteries are stackable, with the option to add two more in the future should we decide to expand. The whole project came in on time and on budget at £11,655. As this was clearly a major investment, the payback period was very important to us. The OpenSolar prediction estimated a 5-year payback. However, after running the system for nearly a year and reviewing our actual performance data, my own calculations suggest it is likely to be closer to 4.5 years — which is even better than expected. A sincere thank you to Oliver and the whole team at FEC Renewables for such a positive experience from start to finish.

  Thank you, Matthew, for the fantastic and detailed review and for recommending FEC Renewables Ltd. I’m delighted Mark, Oliver, Jackie and Elise made the process seamless, kept you fully informed, and delivered the project on time and on budget. It’s great to hear the EcoFlow system is performing even better than predicted and that you have the flexibility to expand the batteries in future — we’re always here to help with monitoring or upgrades. We really appreciate your trust and feedback.

  From initial enquiry to installation and then post sales aftercare FEC have been there with me. The plunge into solar led to wide ranging quotations from a number of suppliers but FEC were the only ones to arrange a call to scope out what I was looking for and arrange an in person visit from Oliver. Oliver came when he said he would and looked at all the options with me; discussing different equipment options and prices; and answered any queries I had. Jackie and the back office team then took care of all the paperwork which given some oversight of a previous EV Installer was more complicated than should have been but the team were great keeping me informed and gained the approvals necessary; and even came back to me when a new variant was released just a week or so before my install to see if I wanted to swap or stick as was. They also allowed me to add an EV charger to the system without any issue. & amended the paperwork after realising a mistake I’d made when ordering which given the volume that’s generated due to the certifications was appreciated Morning of the install and the electrician was here bright and early to verify nothing had changed and then go for the parts needed; then the rest of the team arrived and set to with the works required. All done in one day, rubbish taken away, Oliver visited whilst the team were here and checked everything was going to plan. A great installation and currently discussing an expansion to the battery system and FEC are on my list when the boiler plays up to look at swapping to an Heat Pump & maybe some localised Solar on a separate building. 16 Aiko Panels 10kWh Ecoflow Battery Storage 6kw Ecoflow inverter Ecoflow PowerPulse 2 EV charger Bird netting 2 sides scaffolding G99 & EV charger approvals

  We are very pleased that we chose FEC Renewables to install our solar panels, battery, heat pump and EV charger. Oliver came all the way from Doncaster to County Durham to explain how everything would proceed and after comparing some other quotes it was a straightforward decision to go with this company. The installation took a week, starting with the plumbing team who replaced several radiators and put in the large water tank and heat pump plus kindly installing some new outside taps at the front of the house. Then the electricians who wired everything up and threw in a second light switch for our garage free of charge. Finally the panel installers including Oliver himself who turned up towards the end and made some improvements to the original design plus kindly helped me install some hooks in the garage wall to hold a barbell. Everyone was helpful and polite throughout. All has been left very neat and tidy and everything has been working very smoothly for six months so far. It did take about nine weeks before we could get paid for the energy we sent to the grid, which was a bit frustrating in such a glorious late Spring. However that was mostly out of FEC's control. After sales care has been excellent and just recently Oliver was very helpful with some advice about how to get the best use from our car charger via the app.We'll see how the heat pump copes with winter demands but up to now we declare ourselves very happy with the whole process and strongly recommend this company. If my parents decide to have panels installed, I will certainly point them in the direction of this company!

  I moved into a new property and needed a boiler replacement urgently. Wanting to make an environmentally friendly choice, I asked about a heat pump installation, possibly with solar later on. The survey engineer who visited was very polite and reassuring. He told me that the Boiler Upgrade Scheme (BUS) grant approval would take 2–3 days and that installation would follow the next week. Based on that assurance, I decided to proceed. Unfortunately, the installation did not happen as expected. For about three weeks, I was told repeatedly that the grant approval was “imminent.” During this time, I had no hot water and was relying on updates that never materialised. I became increasingly frustrated because I had made my moving plans based on their initial timeline. When I expressed my concern, the conversation with the engineer became uncomfortable and upsetting. After that, I spoke with the company owner, who was courteous but again gave assurances that didn’t lead to any progress. At this point, I’ve decided to cancel the BUS application and arrange a standard boiler installation instead. I am delighted to share that I went with Octopus in the end. They did a thorough survey and BUS application got approved in 1 day. It has been 4 months and very happy with the heat pump, installation and aftercare and I paid less than what was quoted. So all in all happy that this happened and had a stress free heat pump installation. I’ve also noticed that my reviews on trustpilot were reported and removed, which has made it difficult to share my genuine experience. Please be careful of the positive reviews on Tustpilot as this business is misuing the report functionality and bullying all the negative reviews to be removed. Internet is an open place and all genuine reviews should be made available to public who relies on these reviews to make decisions. I hope this one remains, as I believe all customer experiences—positive or negative—should be visible to help others make informed choices.

  From the moment I got in touch with FEC Renewable LTD, I knew I was dealing with a company that genuinely cares. It’s a family-run business, and that really comes through in how they treat their customers. Oliver was fantastic—he didn’t just send over a quote based on Google Maps like others did. He actually came out to inspect the property, took the time to understand what I needed, and gave a proper, thoughtful recommendation. He suggested a system with 10 x 450W panels, an inverter, a battery, and a new fuse board—far more comprehensive than what I was offered elsewhere, and at a very competitive price. What really stood out was the lack of any pushy sales tactics. It was all about what was right for me, which made the decision to go with FEC an easy one. The day before installation, I got a call confirming everything and letting me know when the team would arrive. They showed up right on time and just got on with it while I worked from home. They were polite, professional, and efficient. They asked for a quick tour to confirm where everything would go, and then split into teams—roofers on the panels, electricians on the rest. By the end of the day, everything was installed, cleaned up, and explained clearly—including how to use the app to monitor the system. Oliver even followed up with a call to make sure everything was working well and to see if I had any questions. Since the install, I’ve already noticed the benefits: My electricity bills are lower I’m using clean, renewable energy I’ve got backup power thanks to the battery And I feel good knowing I’m doing my bit for the environment If you’re thinking about solar, I can’t recommend FEC Renewable LTD enough. They made the whole process smooth, personal, and stress-free.

  FEC have been a great firm to deal with. We were unhappy with the proposals from first company we approached about a heat pump installation – it seemed that firm had a limited set of options and just couldn’t meet our needs. We’d almost given up but decided to try one more time. FEC were very helpful, had a larger range of options and equipment and their price was competitive. Installation went smoothly over four days. The heat pump is unobtrusive and very quiet. Their workers were all pleasant and efficient; minor niggles were promptly sorted and we’re very happy with the new system. I’d definitely recommend asking them to quote for your plans.

  FEC Renewables did an excellent job! Great workmanship throughout. Oliver is a very pleasant and professional guy, and his team was efficient and hardworking. The father and son plumbing team were also fantastic—quick, tidy, and clearly experienced. Everything ran smoothly from start to finish. Highly recommend!
