What our clients say about us
Ritchie has been looking after my generators for the last 22 years, first with Turner Diesel and a couple of other firms before branching out with his own company GCM. We’ve always had a good relationship and have found him helpful, reliable and very knowledgeable, the go-to guy for all things generator-related. His particular forte is panels, switchgear, fault finding – he excels in these areas!
He currently looks after all my generators and has managed many projects including complete replacement installations within the Parliamentary Estate.
