I had the pleasure of working with GMI Electrical on a recent SolShare installation project in South Wales. Their team's in-depth knowledge really shone through when discussing the technical elements. They were incredibly professional and efficient, and their focus on client satisfaction was evident throughout the entire process. The end client is absolutely delighted with the final system. I highly recommend them for any electrical work, especially involving renewables. They're a great team, and I look forward to working with them again
Very grateful to GMI for a complex job today in an old house. Gareth was wonderful and easy to chat with all day. Would absolutely come back when needed.
Wonderful service. The boss is extremely professional and reliable. The boys who arrived to do the job arrived when they said they would and completed the work to an extremely high standard. They were the loveliest, most polite young men who did the job with no fuss and you couldn’t even tell they’d been once they’d finished. They were so clean and tidy. Would highly recommend this company.
