Extremely happy with the service I received from the team at CIS. We had a new boiler installed and the job was carried out very professionally and efficiently - more importantly, cleanly! I would not hesitate to recommend Graham and his team.

I have used CIS for the last few years for Gas and Electric services for my own home and a rental property. I have been really pleased on each occasion, competitively priced, friendly, helpful , efficient and tidy! I would happily recommend them to others.

Having worked with Graham and the team at C.I.S. for some time now, I can certainly recommend their efficiency, politeness and very competitive pricing. No job too small, too large or too much trouble, with all ends being met to satisfy the customer. If you want a job well done, C.I.S. are the ones to call for both gas and electrical.

Graham and the team were a delight to deal with - professional, personable and capable. They quoted a fair price, did a terrific job, and were helpful and thoughtful. Happy to recommend,

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.
