Luke and Daniel installed our solar panels this week in Maesteg. They did a fantastic job, very efficient, clean, pleasant and polite. The panels look really good, they are quite unobtrusive. The battery and electrics have all been put very neatly on the wall in the garage and looks really good. The scaffolding men and the roofers installing the panels were excellent also. They explain everything to you and you are helped to set up the app. They are available if you’re not sure of anything and ongoing, will monitor the system for any faults or issues that may occur. I would highly recommend Quantum Renewables Ltd for your solar panel installation. From a very satisfied customer

It was a pleasure doing business with John, Luke and Dan. John gave us a no nonsense explanation of the benefits of solar, accurate pricing and what to expect on installation. Within 4 days of signing the contract the scaffolding was up and 3 days later the installation began. Luke and Dan together with their roofers installed the panels and EV charger, and did a fantastic job. It was obvious they took great pride in making sure that everything was completed correctly and looked neat and tidy. All the necessary paperwork and contact with energy suppliers was done by the team, so the whole process was effortless for us and very professionally done by the team at Quantum Renewables Ltd. I would highly recommend them to anyone thinking about installing solar panels.

Installed my panels, battery and now a car charger. Quality workmanship and knowledgeable team. Great support as well, willing to help with questions even 3 months after the installation.

From start to finish I have found Quantum Renewable a first class company to deal with, with John doing the initial survey, the job was coordinated within 2 weeks it was completed, I experienced only honesty with all involved in the company, Luke and Dan were beyond excellent in their manner and workmanship with no corners cut. John is with you every step of the way even helping you to get the most cost effective tariff from Octopus to ensure maximum savings. I can recommend Quantum renewables 100 percent, so glad we chose them.

1st Class Service, would highly recommend Quantum Renewables. Had 24 solar panels, 10KW inverter and 13.5KW battery storage installed a couple of months ago, we couldn’t be happier with the savings seen in our electricity bills since install. Massive Thank You to Electricians Luke and Dan for the install and John for providing the initial quote.

They provisded great advice throughout. Would recommend to anyone thinking of istalling a solar system

John, Luke and the rest of the lads (even the scaffolders that were needed) were absolutely fantastic from start to finish and the battery system that was fitted is brilliant. The sales process and workmanship were both first class. I've made significant savings on my bill too! They even fixed the solar panels that I already had when a squirrel had chewed through the wires! So I would highly recommend Quantum Renewables for any of your solar needs

Excellent service from start to finish. Great advice from John on product selection, clearly explaining the benefits in easily understandable fashion. First class installation and we were very well looked after by Luke & Dan the electricians and even the roofers and scaffolders who were efficient and polite. Highly recommend!

We recently had a solar panel system installed by Quantum Renewables Ltd and couldn’t be happier with the experience. From the initial consultation with John Collett, who was knowledgeable and straightforward, to the installation carried out by Daniel Lewis and Luke Wines, everything was handled professionally and efficiently. Special thanks to Jon Cox for the excellent roofing work, ensuring everything was secure and tidy. The team was punctual, courteous, and answered all our questions throughout the process. We’re already seeing great performance from our new system and would highly recommend Quantum Renewables to anyone considering solar.

First class service from start to finish - from sales staff, scaffolders, roofers and electricians. The whole process from initial consultation to panel & battery install took less than a month, and the technical support received post-install has been great. Thanks very much to John & team!

I’ve seen the plastering work done by Cayden, Ryan, and Adam, and I was seriously impressed by the quality of their finish. Their professionalism, punctuality, and attention to detail are clearly top-notch. The walls they worked on were flawlessly smooth and ready for painting with almost no need for touch-ups. They carried out the job efficiently, kept the area clean, and were respectful of the space throughout. From what I’ve observed, they’re friendly, easy to communicate with, and clearly take great pride in their craft. The quality of their work really speaks for itself. Based on what I’ve seen, I’d have no hesitation in recommending Cayden, Ryan, and Adam to anyone in need of high-quality plastering. Excellent work!

After having a few solar companies out to discuss my requirements, John at Quantum Renewables was the best by far, rather than try and sell me stuff I didn't need, he took the time to understand my needs, talked through all the options and didn't pressure me. He was a lot more knowledgeable than the other people I had out and I can highly recommend.
