A Hampshire electrical contractor with the head office in the county

Rossair started in Alton in 1973 and the head office is now at Basing View in Basingstoke, so Hampshire is home ground rather than a coverage area. Electrical work sits alongside the heating, ventilation, air conditioning and water hygiene work we already do across the county, and the longest-running contracts show what that looks like: Chichester College Group has had mechanical, electrical and building services from Rossair across 11 campuses for over 20 years.
