Welcome to Dennis Johns Service Group
Much has changed since we began providing security and electrical solutions to our public sector and corporate clients nearly 40 years ago. We have expanded and innovated. The technology we use is increasingly sophisticated. We ensure we exceed our clients’ requirements so that we can deliver the one-stop solutions which they have come to expect from us. But, at the heart of Dennis Johns Service Group, is a philosophy based on quality work, customer service and competitive pricing. We have evolved and our traditional values keep us ahead.
