Legionella Risk Assessment and Water Management Services for Lighthouse Facilities

The Northern Lighthouse Board operates 208 lighthouses across Scotland, the Northern Isles, the Western Isles, and the Isle of Man, with 66 stations having water systems requiring legionella compliance management. These remote and infrequently visited sites (with some visited only annually or biennially) use water for washing, showering, and toilet flushing, with bottled water provided for drinking and cooking. The Board seeks a qualified contractor to: conduct legionella risk assessments and remedial works at road-accessible sites; perform desk-based risk assessments for remote locations; provide advice and testing regime recommendations; answer ad hoc legionella-related queries; and deliver technician training approximately every three years. All lighthouse stations have UV and particulate filters, supplemented by silver-stabilised hydrogen peroxide dosing, but the UV systems are switched off between visits. Contractors should note the unique challenges posed by infrequent site access and varying maintenance schedules. Full technical specifications are available in Schedule 2 of the Requirements Specification.
