Walsh was established in 1984 when Ian Walsh left his employment to work as a sole trader providing Electrical Services as a sub-contractor to small businesses and domestic customers. The company became incorporated in 1990 and in October 2003 the company changed its name to Walsh Integrated Building Services Limited to reflect the emphasis and direction of the company.

The company now solely provides Electrical and Mechanical Services to Commercial and Industrial institutions. Walsh Integrated Building Services have enjoyed planned growth over the past 20 years and has gained over this period an outstanding reputation across the industry. Walsh Integrated Building Services are proud to provide their engineering services to numerous Blue Chip clients.
