Established in 1985, G & A Barnie Group has built a strong reputation for quality workmanship and client service. Initially focusing on electrical installations, the company has expanded significantly, opening its group headquarters in Inverness in 1991. This growth led to the formation of Bartec Fire and Security in 2003, specializing in alarms, CCTV, and security systems, and later expanding into mechanical installations and maintenance.
The group now operates numerous branches across Scotland and beyond, undertaking multi-million-pound projects. Their commitment to quality is underscored by ISO 9001 and ISO 14001 accreditations. The formation of Barres in 2011 introduced renewable energy solutions, including heat pumps and solar PV, while the water treatment division, established in 2012, offers Legionella prevention and water management services.
