James and team installed solar panels, an EV charger, a domestic hot water heating system, and a solar battery system for me last year. They were totally professional and extremely helpful… and really nice guys to boot! 😊 James did all the design and calculations to specify a system for me which has proved to be ideal - it operates at pretty much optimum for my particular circumstances and property. My property has 3-phase electrics and I didn't want the battery inside the house, so James spent time with me assessing both my needs and concerns and didn't just try to install a 'standard' or 'simple' system for me as some other firms wanted to do simply because it was easier for them. I thought the price James quoted was really competitive and I am very happy with the results. I'd recommend them to anyone, although I try not to in case they're too busy with other work if I need them to do some more work for me 😉 After all, if you all used them too I might have to wait a long time for them to have any availability for me! Obviously I'm just kidding - if you want an excellent, extremely knowledgeable, helpful, and professional team then you can't do any better than Derbyshire Electrical Services Ltd.

Like others I was connected to James through Hypervolt. Can honestly say James was quick to respond, dealt with a small issue with the case really well (Hypervolt supplied a unit with a label that couldn’t be removed and a small scratch). I’d have no hesitation recommending James.

I am extremely happy with the quality of work done by James/Derbyshire Electrical for my solar panel installation. James was really professional and his customer service is second to none. I highly recommend James/Derbyshire Electricals for all your Electrical works.

I went through HyperVolt's website to look for approved installers and was connected to James who did a remote survey and explained everything involved with fitting an EV charger on a video call. James was attentive and listened to my concerns of making sure the installation was neat as I'll be looking at it every single day. Unfortunately, one of James' staff had an emergency on the day of the installation so we had to postpone. James made me aware as soon as he could and offered to come and complete the job at the weekend. I was in no rush as my EV was still on order so I suggested we do the following week instead as I don't like working weekends either! Jason did an excellent job at making the install look neat and answered any stupid questions I had along the way. Jason showed me how to use the HyperVolt app and made sure all the settings were configured correctly. Thanks James & Jason for doing a superb job at a reasonable price.

James is an exceptional electrician who went above and beyond whilst installing our solar panel and battery system. His deep knowledge of solar systems was evident from the initial consultation, where he took the time to explain every component in clear, understandable terms. The installation itself was executed with remarkable precision, and his attention to detail was impressive—from the perfectly aligned panels to the meticulously organised wiring. His professionalism and customer service were outstanding throughout the entire process. James was consistently punctual, responsive to all enquiries, and kept me updated on the project's progress at every stage. The final installation passed inspection without any issues, and the system has been performing faultlessly since day one. I'm already seeing significant savings on my energy bills through optimised solar generation and battery storage. James is, without doubt, the gold standard for solar installation professionals, and I wholly recommend his services to anyone considering a solar system for their home.
