About us – Specialists in Private Boat Hire on the Thames

Thames Leisure is the only Thames boat and event company that operates from the City of London. Established in 1984, Thames Leisure remained a family run business for the next 25 years as the fleet expanded with the arrival William B in 1998 and Dutch Master in 2001. Thames Leisure’s diverse fleet quickly gained a well-earned reputation on the river for its versatility, professionalism, and quality as well as its competitive value for money. Today Thames Leisure is one of the busiest fleet operators in London, creating imaginative and professionally run events for both corporate and private clients.
