10 Excellent service – professional, reliable, and friendly
Posted 10 January
Job location: GU22I’m very happy with the service from GM Electrical Service. Garry was professional, punctual, and carried out the electrical work to a very high standard. Communication was excellent throughout, and the job was completed promptly. Katy was also great on the customer service side – friendly, helpful, and efficient. A reliable and trustworthy company that clearly takes pride in their work. I wouldn’t hesitate to recommend them and will definitely use their services again.10 Expert Electrician

Garry Markham was recommended to us as unusually expert in his field and indeed he has carried out work for us which was very effective, undertaken very quickly and with the minimum of disruption. On this occasion he installed an up-to-date (fuse board) consumer unit to bring us into compliance with today's standards. He was flexible when we wanted to adjust the timing of the work and charming as ever.Verified reviewerJob location: GU5- MMichael D
