JMG Renewables

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..

I was very sceptical about solar panels but found JM Renewables and I have now a 50 kWh system in place this week and I cannot praise the team and the company enough, excellent staff working here and the panels working a dream, extremely pleased from start to finish, let the sun shine, thank you

Extremely Poor Customer Service. I have tried contacting This company on their various platforms over the last two weeks to try to obtain the DNO letter for my Solar Panels supplied by JEM. I can not sign up for a Utility Tarif as ive just bought the property and cannot register it until I obtain this from the company. Due to this issue with the company being unobtainable I am being charged the highest tariff. I am at a total loss as what to do.Can any one on here give me any advice on how to contact them.Many Thanks.

We have spent several weeks speaking with a number of Solar Panel companies as we decided to make the decision to add 18 panels with a 13.1kw battery to our property. This is a big decision for us and scary as we have little knowledge of the market. Have to say from first meeting Dan to discuss our needs to the installation so far this company is excellent. This is only day 3 and the panels are working wonderfully so will update my review several months down the line. Special mention has to go to Simon who kept us informed during the install and Gareth the electrician worked with us to find the best location for the battery to look good on the house. Lots of people helped sorry to miss people out but all were fab, Ewan, Steve and probably more came. The place was left spotless even after the first day and honestly we are so happy. Every query in the early days was answered by Dan promptly and the site visit was re-assuring, absolutely no pressure selling. Have to end with a special mention to the scaffolding company sorry not sure of the name, thankfully they didn’t leave us with ugly scaffolding longer than absolutely necessary band for that we thank them.

From the initial contact and all the way through to completed project the Company and Staff have been first rate. The office has always dealt with matters very promptly and efficiently and the installation of the solar panels and battery storage despite being not straight forward was excellent with quality workmanship. Would definitely recommend.

It was a pleasure dealing with JM Renewables. They dealt with my initial enquiry promptly and professionally, and their staff made me fully aware of the work that had to be done, together with the cost. The supply and commissioning of the new Air Source Heat Pump and hot water tank went very much according to plan, and the technicians who handled the installation were hard working, competent and polite.

From the first contact, good communication,dates agreed,times ext.All costs in writing with a plan of how money's to be paid and when.Then work carried out to a schedule. very professional.

JM fit a charge point for me last week. The electricians were really friendly and talked me through a few options. Sheila kept me updated with when anyone was arriving. Good price too especially for the service received. Thanks againCharlotte

The PV panels came unprotected, scratched, shoved sideways in the back of a small van. • No measurements were used to install the clamp brackets. It was done ‘by eye’. This meant that when they missed the batten with the screw (which happened numerous times), they simply drilled another hole slightly higher/lower. On inspection, one clamp which was loose had 5x holes at random places to try and hit the batten, which would have definitely leaked into my roof.• All screws were put in with an impact drill. In summary, the end result here after final inspection was that 25% of the screws in the clamps were turning (threaded) meaning they had been over-torqued. • The side flashing were installed but they would not fit the top flashing. They did however put something called ‘fast-flash’ over the joint of the plastic panels. Instead of removing the backing plastic fully from the fast-flash, the guys installing thought it was acceptable to scrunch this up and stuff it down between the battens and the membrane. • Regarding the top flashing -I was concerned that they were not planning to install the top flashing. The guy installing, said that they never install the top flashing at JM Renewables. This is how they do every job. I rang the director on numerous occasions, and I have a record of the pictures I’ve sent to him, and he reassures me numerous times with statements like: “trust me, I can guarantee it won’t leak”, “I am a company director..” and “we’ve done over 500 of these systems, we never install the flashing”, over and over again. I ask him to order the correct flashing, but he said they have a 3 month wait (I later found that I could buy them online next day delivery), I even ask if I could get my local fabricator to make them, but he said they are specialist items with “solar-rated coating”, and that the warranty would not be covered if I did this. I sent him a copy of the GSE installation manual, but he just ignored it, and sent me pictures of a completed job with slates cut around the raised section of the GSE panels, this would create a direct leak-path to the membrane without the top flashing! I had to get Building Control involved, as this seemed like the only way to get through to the technical director, and confirm that their method of installation was indeed incorrect. The "Technical Director" tells the Building Control they are “not a mickey mouse company”. Building Control recommend asking the manufacturer of the system (GSE) to confirm if what they’ve done is acceptable. I email the same picture I sent to the Technical Director a couple of days ago – to GSE, and they email back very quickly saying I have 2 options -fit the correct flashing, or use lead flashing. I email back saying I hope this is conclusive. But then the Technical Director replies by saying “it’s the first time he has seen this picture” and that they always fit the flashing on their PV installs (with Building Control copied in). To me, this concludes that he is a prolific liar…• The panels was meant to be positioned centrally on the roof, but it ended up being about 400mm towards one side of the roof. • They did not send me the electrical connection agreement.• I had cross-battened my roof. If I had not done this, they would have screwed all the screws that secured the panel mounting, and clamps through the membrane! (note the penetrated the 1st batten by ~15mm). this is probably what they do on most retrofit jobs.After all this, I noticed some of the clamps coming loose, so got back in touch. Without letting me know about it, someone turned up and went up (on my scaffolding) to inspect when I wasn’t home, I saw it on my CCTV. This is in itself -trespassing! But it turns out they installed the wrong sized panels, so all the panels had to be replaced with a different brand. They left the panels vertical on the scaffolding and went to get something from a local supplier, and wind blew one of the panels over, but luckily it did not break..Overall I think you get the idea of what sort of company this is. Unfortunately, most people will not see how incompetent they really are.

Overall happy with the service. An investment I'm happy to make and now it's all joined up I'm excited to see my bills drop!
