What KMM customers actually say

"Decided to get solar panels & battery storage after umming and arring for 6 months. If you're unsure about staying in your home long-term, think carefully — it's a large investment with no guaranteed return on house value. Kieren from KMM was great from the start — no pressure selling, gave me time to decide at my own pace, and built a system spec tailored to our current and future usage. Scaffolding: The crew were careful and professional on site, but the lead was reportedly rude to customers over the phone (suspect they use different scaffolders for different areas but worth a note because it wasn't very professional and makes KMM look bad). After they installed roof brackets, I went up myself and found cracked tiles I suspect wouldn't have been flagged — they were replaced once I raised it. Don't be afraid to check. Also, the guardrail poles were overlapping and clanging loudly in the wind at night — I fixed this myself after the installers had left. Scaffolding was up around 3 weeks total (monitoring required before removal) — worth warning neighbours in advance. Commissioning electrician: Friendly and knowledgeable. There was a wiring issue with the gateway on the day, but it was fixed quickly the following morning. He followed up afterwards and even offered a free weatherproofing upgrade — great customer care. Most frustrating part: The DNO approval process for SEG payments. My system was commissioned mid-January and I didn't receive export payments until end of March. I handled the paperwork myself which likely sped things up — I've heard others wait 6 months. Be prepared for this. Overall, happy with KMM — just go in with eyes open on the admin side. Know what you're investing in and how to use it to its maximum. Thanks Kieren, Lewis and Roxanne. Very pleased overall."

"Had an excellent service whilst installing my solar and batteries. The installation was smooth and quick. During the whole process I was kept up to date by the team. Thanks to Steve, Marcus and Roxanne."

"I first enquired 4 months ago and soon got chatting to Kerin and we got on straightaway. He was in no way pushy on the sales and was there to answer any questions I had. He did all the relevant applications for me and the install was straight forward and done very quickly after the paper work cane back from UKPN. Also I am now getting paid for my solar I produce that I dont use on the farm. This was all sorted in less than 12hrs. Thanks Kerin and the team at KMM and also the guys from Peak Solar who carried out the work on the farm installing the panels great job all round. Would highly recommend"

"KMM helped us through the process of installing solar panels on a Listed Building, getting permission with good communication and lots of help. Marek and Roxanne were helpful and the AIM Eco team were very hardworking on site."

"We recently had 21 solar panels installed in our property and cannot fault the service from Jon and the KMM team. We met Jon and Kieran at a local show and they were extremely friendly, professional, knowledgable and not pushy at all. From start to finish we cannot fault them and the continued support of having them there to help us choose the best energy provider and package has been brilliant. Thank you guys. Keep up the good great work."

"We recently had solar panels installed on our period property and couldn’t be happier with the result. Keiran was great from start to finish – knowledgeable, practical, and always prompt. He really understood the character of the house and ensured the installation was sympathetic to the building while still delivering excellent performance. The installation team were fantastic – hardworking, professional, and respectful of our home. They started early each day and stayed until the job was done, even working through terrible weather without complaint. Communication was clear throughout the whole process, and they left everything clean and tidy afterwards. A thoroughly positive experience and we would highly recommend them!"

"Jon Came to see me after I enquired online. He was very knowledgeable, well informed and not pushy at all. I was kept up to date throughout the install of 31 panels, sigenergy 8kw battery, 10kw inverter and gateway, even when there were issues in sourcing the Gateway. Install team from RLW were also great. System has been in for a few months and working well. Would definitely recommend."

"After several years considering panels, Steve came out and designed a bespoke plan for our rather disjointed roof. He explained things simply and kept in touch throughout the process, doing his utmost to answer any queries."

"Great experience working with KMM & especially Kieren on a 63kw system on an agricultural shed roof. Easy to deal with, quick at responding and plenty of enthusiasm!! The installers AIM-ECO where really efficient and the electrician Lewis was particularly good and very helpful. Great team, would highly recommend."

"Great experience from planning to completion, everything explained, the team always on hand to re explain and always approachable. I highly recommend 👍"

"I met KMM and Kieren at cereals event last summer and he was very easy to talk to, knowledgeable and answered any question I could think of! Booked a convenient time for Kieren to come to the house to measure up Kieren came up with a plan, kept in touch throughout and before we knew it, the system was installed 14 panels EV charger and a battery all very well installed with all wires routed well with little disruption . Very pleased would recommend to anyone thinking about it to talk to kieren!"

"Kmm are so easy to do business with. I phoned to ask questions and spoke with Keiren and after our discussion he said he could send his local guy Jon around if I liked. So I could get proper figures. There was no pressure at any time. Jon phoned a day or so later and arranged a time. Everything made sense because Jon explained so well. Once everything had been set in place, everyone turned up and did their thing, it was like clockwork, everyone knew their job, worked in unison and cleaned up afterwards. Jon organised everything perfectly. We had a problem with my old fuse board but Ricky sorted that out and now all seems excellent. I'm just waiting now to see how the next couple months affect my electric bills. I'm really happy with the whole experience. Jon definitely knows his stuff and sticks with you if you have any queries. His dedication to good service is exemplary. Even after completion, Jon still answers my contacts promptly. He's there providing good after sales no matter what. No wonder he's so busy. Kmm have definately got the right man for the job in south wales. Thank you team. You're awesome. Oh, and the cost of the system....its £100 pcm less on finance than my summer bill from the electric company. And that's without what the system produces into the equation."
