Stephen Mills
I've known Graham at CIS for 10 years now. I've called on his help many times over this period and I've always valued not just the work itself but the practical and pragmatic advice and problem solving that goes with it. He has our complete trust and I have no hesitation in recommending him highly.

Katy Gray
We have used CIS for several years now and have always been happy with all aspects of their service. As a busy Agent managing 350+ tenancies it is imperative that when using a contractor they are professional, trust-worthy and just as importantly value for money. Graham and Paul always respond to our instructions promptly and offer the most cost-efficient solutions. They are professional and friendly with Tenants and we have no concerns with recommending them to our own Landlords but also Friends and Family too.
