J and M Renewables Ltd

We have just had Gregg installing a Eddie water diverter for us since the one we had 10 years ago from JM had packed in. His work was meticulous and nothing was too much for him. And he and Matt just got on with it in a corteous manner until we were fully informed and job complete. Both were ver knowledgable and credit to your company.

Fantastic job completed by JM Renewables for Solar and Battery at my property. I'm glad I chose JM, can always get hold of someone on the phone and the aftercare has been second to none. Daniel in the office has been excellent and responsive around quoting and all the Green Homes Wales paperwork and getting everything sorted and booked in. Installers were excellent too, both Glyn and Rowan were ace, just cracked on with what needed to be done and were super friendly in the process, answered all of my (many!) questions. Luke the electrician was excellent, really knowledgeable about the system being installed. He also made sure any energy switch offs were around my meetings working from home and has been super responsive to any aftercare queries. We're so pleased we chose JM Renewables for this piece of work and would not hesitate to recommend them to anyone requiring Solar and Battery installations.

Excellent from the sales process through to pre install and install. More than happy, professionals. Refreshing to pay for high quality work by a great team. No negatives at all. Had 16 panels and a 10kwh battery fitted to semi detached..

Martin and his team came out last week to fix a problem we had with our heat pump. They worked over and beyond expectations and after a challenging few hours found the problem. I would not hesitate to recommend JM Renewable Solutions. Their work was excellent. Sheila the office manager was very professional on the phone and kept us updated of any questions we had. First class.

What a fantastic experience and outcome! We approached JM Renewables back in March 2025 to quote for ASHP, PV and battery storage. Dan the project manager assigned worked with us to get just the system we were looking for. Quotes were comprehensive, detailed and even provided data sheets for the kit being installed. As part of the installation we needed our local transformer upgraded by the DNO. Again Dan handled requesting this. Unfortunately the DNO advised the upgrade would take 3 to 6 months to complete (totally out of JMs control). Fast forward to August 2025, DNO had advised when the upgraded would take place, so the work at our home was scheduled to begin! ASHP then PV post the transformer upgrade. Laura and Adam made the schedulling very very easy. The scheduled Monday arrived and Elliott and Alex were on site to start the ASHP. They both worked tirelessly and to a very high standard, all during what was the few very hot days we had this summer. Elliott faced 45 degrees C in the loft but worked on without complaint. The second week they were joined by Jack who also worked to a very high standard. After 2 weeks we had a new heating system! October came and Matt and Mark arrived to start the work on the roof and PV panels. The weather was appalling, it pretty much rained every day, and to make things worse for them we specified an in roof installation so a lot more work for them. Again they worked tirelessly and completed the work to a very high standard. Then it was Lukes turn to finish off the install of the inverter, gateway and batteries. All nicely installed, tidy and accurately. The whole team was fantastic, they got our humour, we're always polite, tidy, and courteous. I would not hesitate to use or recommend JM Renewables in the future. Thanks to you all.
