Three limited companies and one charity; G4S has held ports security for Guernsey airports and harbours since around 2000. —
Four providers — G4S with 50-plus years on-island, two SIA-licensed close-protection firms, and the volunteer Civil Protection corps.
Three AV firms — Joys Events (1984), Centre Stage, and Guernsey Audiovisual — one each in St Peter Port, St Sampson, and St Martin.
