London is home to the world’s leading classification societies, including the headquarters of Lloyd’s Register and the regional offices of nine other societies. Between them these societies ensure that 90% of the world’s cargo carrying tonnage is safely designed and constructed. The International Association of Classification Societies (IACS) is based in London.
Independent surveying firms based around the UK provide support to P&I Clubs, underwriters, shipowners, law firms and average adjusters in claims handling and loss prevention. The Salvage Association, now incorporated within BMT Marine & Offshore Surveys, is an international surveying organisation closely connected with the London Market, which investigates casualties and can determine the extent and cause of loss.
