About Us

Our Heritage

Mike Shannon started the company in 1981 under the trading name of Mamba Signs. This later changed to Shannon Signs in 2002. Finally changing to Shannon Group in 2018 to reflect the broader spectrum of works carried out by the company.

We still produce high quality signage, but the brand encompasses much more and the company name needs to reflect that.



A business with as many different facets as Shannon Group needs a similarly skilled workforce. With a combined 70+ years of experience in the sign industry, and almost as much again in the manufacturing industry, there is no shortage of knowledge within the company.
