J M Renewable Solutions Limited Reviews

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.

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.

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.

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…

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..

Would highly recommend JM Renewables for your solar and battery requirements. Very knowledgeable and professional from start to finish and completed all works to a high standard

I recently had solar panels and a Tesla Powerwall installed by JM Renewables, and I couldn't be happier with the entire experience. From the initial consultation to the final handover, the team was professional, knowledgeable, and incredibly efficient. A special shoutout to Daniel, the Projects & Estimations Manager, whose expertise and clear communication made the planning process seamless. He took the time to explain every detail, answered all my questions with patience, and ensured the system was tailored perfectly to my needs. Equally impressive was Steve, who led the installation team. His crew was punctual, tidy, and respectful throughout the installation. Steve’s leadership and attention to detail were evident in the flawless setup and smooth integration of the Tesla Powerwall. The system is now up and running beautifully—quiet, efficient, and already making a noticeable impact on our energy usage. I highly recommend JM Renewables to anyone considering solar energy. Their professionalism and customer care are second to none!

I was very sceptical about solar panels…

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.

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.

I had a problem with my solar panels, contacted JM Renewable Solutions Ltd. Communications with this company was first class. Within 2 days I had a visit from their engineers who were very professional, knowledgeable and courteous. The problem was corrected within an hour and they fully explained what had been done. This was a fantastic experience from start to finish. A massive thank you to all involved.⭐️⭐️⭐️⭐️⭐️.

JM Renewable did a large PV installation with battery storage on my detached garage and it was linked to my house. They did an excellent job but I must give praise for the way they went above and beyond expectations in helping me sort out a problem with mains electricity supplier. In short the voltage from mains electricity distribution from the national grid was far too high and was causing problems with my PV installation which resulted in my system going into fault mode and not working properly. The electricity company were not interested in sorting out the issue, (apparently this is a national problem of an inadequate distribution network), and it was only with the assistance of JW Renewables that I managed to get Scottish Power to rectify the problem. Many thanks to JM Renewables.👍

After looking around for Solar panel installers and with very little knowledge of the market we found JM Renewables. We met with several other companies. 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.

Early Days Review

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.

Highly Recommend

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.

Professional, efficient, dependable and polite

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.

The installation ran very smoothly, and everyone working on the installation did a professional job. Up and running after a week, and all pipe runs and cables are tidy and unobtrusive as are the pump and cylinder locations. Well done team JM Renewables! Well done team!

Air Source Heat pump

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.

EV Charge Point

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 again Charlotte

Overall a terrible experience.

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.

I recently contacted JM Renewables to assist with a failed air source heat pump unit. I can't thank the engineers and electrician enough...they were very thorough, knowledgeable and were able to clearly describe issues with our system and resolve them. The electrician fitted kit that had been redundant for nearly three years! Excellent company I would highly recommend.

We’ve had our Mitsubishi ecodan 14kw air source heat pump supplied, fitted and maintained by JM for the past 5 years. We had our first problem today with the underfloor heating losing pressure and loads of air bubbles. General error fault on the system. We rung them on the Thursday afternoon and Jeff came out on the Friday and sorted the problem. (The issue wasn’t actually anything to do with their installation either). Just generally a really good company to deal with. Sonia and Martin in the office arranged everything pronto and Jeff, the world’s nicest man, came out and worked his magic. Can’t recommend them enough.

Overall happy with the service

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!

Simply Superb

In terms of workmanship, excellent. Helpful and considerate in ensuring that any inconvenience was minimal, during the upgrading of the loft insulation, installation of the ASHP, central heating and fitting of the solar panels. All of the craftsmen went that "extra mile" to ensure that we were happy, the job done expediently and proactively, using their initiative and resolving any problems that arose.

Excellent work!!!

Dion and Joe came to my parents home to install solar panels. No mess, no fuss and very efficient. Their work was exemplary and they were perfect gentlemen. I couldn’t recommend these guys highly enough. Five stars all round. ⭐️⭐️⭐️⭐️⭐️

Brilliant service by friendly and very skilled workers

Gareth and Kristen turned up on time and ready to get the job done. They were lovely people who worked hard and were very neat and polite. Gareth went above and beyond to site our batteries/inverter and connect them up in a rather tight and difficult to reach position. Kristen made sure that he fixed the solar panels centrally on the roof in a very neat and sensible position. They made an excellent team and I would highly recommend them.

A pleasure to have at our home

Excellent communication from the very beginning, everyone from JM Renewables we met or spoke to was friendly, very knowledgeable and really helpful. They went out of their way to make the process easier for occupants with additional needs, explained everything they were doing and were a pleasure to have at our home.

Edit: Since the review below was published, JM have now visited and resolved all the issues and were very apologetic. These were all really very minor snagging issues in the end (the legionella cycle issue was only caused by a blown fuse of the wrong amperage) which just needed a couple of hours of engineer time to resolve and make a happy customer. It is a real shame that it took me to post a negative review to get a reaction, but hopefully a lesson has been learned. In general the system is a really good system, and works well, and the engineers are all good people and know their stuff. Just the processes for customer support obviously needed some improvement. Had a Mitsubishi air source system installed in March 2023. Various simple but still important teething issues reported including a non working Legionella cycle which is a health and safety issue and newly installed pipework not properly attached to the wall. JM Renewables seems to have no interest in responding or dealing with the issues despite several emails and phone calls over several months. Fortunately I have come up with work arounds to some of these myself. On the plus side the battery system they installed at the same time works well and they were the cheapest of 3 quotes for air source and battery. Come on guys, you can do better....don't just take the money and run.

OUTSTANDING

From introduction to completion this company has been outstanding. The two workmen that installed my panels and got the system working were extremely competent, knowledgeable, tidy and basically so efficient, respectful and pleasant. I cannot recommend them enough…. OUTSTANDING! Thank you J M Renewables!

I had a large domestic solar array with battery storage and EV charging port installed by JM Renewables. They were excellent from start to finish. All the jobs were done in a professional and courteous manner and on time. I wish to thank all the members of the team who worked on the project and a special mention to Daniel Miller(Senior Project estimator) who was prompt with email replies and clarified all my questions and doubts. I am very happy with the work done and have no hesitation in recommending them wholeheartedly.

Overall excellent experience with this company for solar and battery storage at a reasonable price. The communication from Daniel was excellent throughout, the workmanship was completed to a high standard by a team who worked really hard and were very approachable. All of the documentation was completed in good time and allowed me to set up export within a week of install. I had an issue with the battery one evening shortly after install (not their fault) and they sent an engineer out by early afternoon the next day and got it working. So far I am delighted with the system overall.

From start to finish the team at JM Renewable Solutions Ltd have been excellent. The information provided and the speed of responses has been second to none. And really can't fault the installation of the solar panels, battery and inverter (no matter how hard I try). A massive thank you to the team. I can't recommend them highly enough.

Excellent service

Excellent service Solar PV and battery Very efficient, polite and helpful. Job done with minimal fuss, in atrocious weather conditions, tidy work. Goods provided as specified and performing better than expected, we are very happy.

Excellent service, award-winning company

After reviewing multiple contractors, we decided to get a solar photovoltaic system from J M Renewables and were extremely pleased with the results. The consultation through Ben Musgrave and Daniel Miller was top notch. Once we agreed to move forward, we found the installation process very straight forward. The electrician gave us multiple choices where the different devices could be placed (i.e. battery, inverter, Eddi, etc). We very much appreciated that they took time to understand all electrical wirings in our house, and that our requests were fully taken into consideration. Through this solution-oriented approach, it allowed us to best use the space. Even after the commissioning was done, they took great care of us, immediately answering further questions and requests we had. As a plus: The equipment which was used all looked very sleek and modern. The battery has a white glass surface. We were pleasantly surprised. We also appreciated how friendly and humble everyone was. This company has won multiple awards. They have also fitted solar panels on Chester Cathedral, yet they did not even mention this until much later. Excellent and friendly service, and well qualified staff. Highly recommend.

JM Renewables recently fitted solar panels and a battery to our property. Good communications throughout, with a great fitting crew. I would highly recommend them. The work was completed in 2 days. Our roof access wasn’t ideal. Having the job done in mid winter means we don’t know how well it’s working as yet, but we look forward to to seeing good returns from early spring when the sun gets a bit higher.

We recently engaged JM Renewable Solutions to install our solar panels, we would like to say a big thank you to all the staff members within the team. We found all staff to be well informed, friendly and helpful. All of our many questions were answered in a timely manner which enabled us to make informed decisions. We didn't experience any pressure selling which helped us to feel comfortable in our purchase.

Looking at ways to reduce your energy bills? Then look elsewhere

## TLDNR 16 months later... the Centre for Effective Dispute Resolution (CEDR) forced them to pay "compensation for their breaches of the Renewable Energy Consumer Code (RECC) and for the inconvenience suffered by the Consumer as a result". Case now closed. Do your research - it's easy to find bad companies but sometimes bad companies don't come to the surface until you ask them for help and it's only then do you realise the mistake you made. Our mistake was choosing JM Renewable Solutions... ## Introduction This is our personal experience of paying JM Renewable Solutions to design, install and attempt to support a Mitsubishi Ecodan Air Source Heat Pump (ASHP) at our new build. ### Initial contact 5/5 Contact was friendly, polite and eager to obtain our business. ### Design 4/5 The design process was quick and went through several iterations due to changing circumstances. ### Installation & Commissioning 2/5 1. Despite designing the system themselves with a clear architectural plan of the property in front of them, they still managed to bore two 2" holes through the wrong wall. These holes had to be filled in at a later date and the exterior wall re-rendered but the damage can still be seen. 2. Both the ASHP and the boiler had drain pipes fitted leading to an outside drain. However, the copper pipe from the boiler runs upwards, not downwards, so water will collect and freeze during the winter months leading to failure. 3. This is a two zone system, downstairs and upstairs, yet they only fitted one thermostat, which was fitted directly above a radiator!!! 4. Waste material left on site. ### Support 1/5 This is the main area of concern as their response time is glacial, bordering on non-existent and when they do reply it is far from satisfactory. 1. Reported a fault with the main panel rendering the system inoperable - many emails and phone calls later, simply to get their attention, they finally turned up to address the problem FIVE WEEKS LATER!!! 2. Reported issue where only one floor was being heated - the director of plumbing attended and suggested that an upstairs thermostat should be fitted and would get it arranged - why wasn't it fitted in the first place? He gave me his mobile number and said to call him anytime. After leaving many voice messages, sending countless text messages and even emailing JM Renewable Solutions, I have never heard back from him. 3. Considering that one of the main requirements of the system was that it could be controlled remotely, they eventually turned up one day to fit a non-compatible thermostat for the upstairs. It took the incompetent engineer a long time to install and did not inspire us with much confidence. The following day I contacted them with a detailed list of fault finding steps to help explain to them when the system works and when it does not....... 12 WEEKS LATER and the conclusion was "it was working when I left it" and "we're waiting for some new thermostats to be in stock" - we're still waiting. # Renewable Heat Incentive (RHI) We were eligible for the Renewable Heat Incentive (RHI) where we would receive payments over a period of 7 years. JM Renewable Solutions applied on our behalf, which they're not supposed to do, and did so with incorrect information - this nullified our application and thus we have lost approximately £7k. ## Conclusion JM Renewable Solutions are more than happy to take your money; install an incomplete system causing property damage in the process; treat post-installation customer support queries as an annoyance and, for all intents and purposes, simply ignore. While waiting for their long overdue reply, we signed up directly with Mitsubishi for their "3 Diamond Maintenance Cover" plan. The following day, Mitsubishi serviced the system; diagnosed why the Mickey Mouse thermostat that JM Renewable Solutions fitted did not work (wasn't installed correctly); replaced the thermostat with the real thing. It was as simple as pick-up-the-phone, join the plan then open the door to them the following day - job done. At the end of the day, you get what you pay for and in JM Renewable Solutions case, all we saw was tumbleweed and would highly recommend that you look elsewhere. Do your research - it's easy to find bad companies but sometimes bad companies don't come to the surface until you ask them for help and it's only then do you realise the mistake you made. Don't make the same mistake as us.

JM Renewable Solutions Ltd are fabulous! Great communication from start to finish from Dan in the office and splendid over the phone and on site consultation with Ben and his 'can do' attitude. The electrician Joe and engineer Luke really knew what they were doing and were incredibly accomodating and professional. The team of guys doing the work on the roof were all absolutely lovely, so professional, friendly and courteous. Not only that, they were so hardworking, they really put a shift in and worked incredibly hard to get the job done in difficult weather conditions at times. Would highly recommend this company!
