JEM installed a GivEnergy battery system and car charger for us. Everyone was very helpful and friendly and the job was done exactly as promised. Very happy to recommend them.

Jim installled a Zappi EV charger into my home and explained everything perfectly, even with the solar panels . Everything worked first time and has continued to do so. Now I charge with Octopus go 7p a unit. (Yippee)
I then got him back to re do all my totally amateurish electrical extension efforts. Much raising of eyebrows quite understandably and my home is now safe and neat.
His charges are more than reasonable, he’s a delight to be with and I can recommend him wholeheartedly. Philip Milln

From start to finish it’s been superb service. From the initial enquiry, to the survey, discussing options, receiving the quote, organising the installation, scaffold going up, last minute curve ball from me, installation and taking the scaffold down, it’s been seamless and run like clockwork. Quick to respond to queries, happy to explain the technology and supply a quality system that meets your needs. The team from JEM Energy give that bit extra that you want from all trades, but sadly miss at times, but these folks don’t disappoint. No hesitation in recommending JEM Energy for solar & battery installs, top service.

Jem did a great job installing Solar PV and battery. Was super easy to get a quotation and Josh clearly knew his products. Price-wise the quote was reasonable and certainly was not massively over inflated like some chancers currently in the market. Originally I opted to wait for an inverter to come into stock but this was delayed by the manufacturer. I changed my mind which was no problem and got an installation date booked. The install was quick and tidy and done in 1 day with Dan leading the roofing team and Olly and his apprentice on the electrics. There were a few minor niggles which were rectified with no quibbles within 48 hours. Scaffolding came down promptly after the install. Bulk of the paperwork including the all important MCS and building regs certificates arrived quickly and then DNO approval and the electrical installation certificate arrived within 4 weeks. All of my post-install questions were quickly answered by James (apologies for probably being annoying!).

The system is working brilliantly, our grid usage has plummeted and we're getting a bit back on export.

Wouldn't hesitate to recommend them to anyone wanting Solar PV and batteries

We are building a new house in Chalfont St. Peter and from the outset knew that renewables were important to us. For each technology, i judged the merits on the following criteria:
1. Capital outlay, return on Investment and payback period
2. Proven technology
3. Aesthetics
4. Supplier knowledge – from sales to installers
5. The guarantee, lifespan and running costs
6. Communication/co-ordination and flexibility with on-site team.

I was really impressed with the collective JEM team, from sales to completing installation. The team were all super knowledgeable. My main contractor and my project manager were also very impressed with the team and my main contractor mentioned “… in all the renewables he has encountered, the efficiency and return of the thermal hot water system was certainly the best he has seen… “.

Thank you again and highly recommended.

Jem were recommended through a friend and my experience pre and post Solar and Battery installation has been amazing.

After spending months and months researching and trying to find an installer I could trust, I would recommend Jem to everyone and looking back now, there is nothing I would change.

James who is the owner is fab and answered all my questions.
- Once we agreed the system, they applied for DNO and once that was approved, we were good for the install.
- The install team on the ground were superb and got it all installed within around 7 hours and as an end user the quality of install was high and the panels were symmetrical on the roof - a must for us, needed to look great.
- Post install the system is working better than expected and loving the generation. The paperwork has come through inside a week also.

In summary:
- Communication, quality of install and price point; all spot on.

This being such a big purchase, if I had to do it all again, would definitely use and recommend Jem again (and I am picky 🙂 )....

We used Jem energy, really pleased with our set up. The electrician who hooked it all up is so friendly, approachable and knowledgeable, just felt complete confidence in him so huge thanks to Ollie.

We’ve had office support from Josh and Tony (there are others but we’ve not dealt with them personally, zero hesitations they’re also excellent!).

Now we’re enjoying checking the app, seeing how the system is doing, and look forward to including a solar diverter soon too.

Thanks everyone at Jem!
