The research, conducted by Visit Britain, is gathered from interviews with 50,000 overseas tourists as part of the government’s International Passenger Survey.
Visit Britain head of business events Simon Mills said: "It is very encouraging to know that that 92% of the 6.5 million business visitors who came to the UK last year had already visited in the last ten years and chosen to return to Britain. It is an important sign that Britain is ready, willing and able to generate a sustained uplift in tourism after the Olympics.
"Britain is ready for more returning business visitors, we have the infrastructure in place, we have the world-class venues to host them and the fantastic service providers in place to support them."
Elsewhere, the survey revealed that business travellers from Luxembourg are the most loyal to Britain, with 96% of those that visited the UK last year having dropped in at least once during the previous decade. The Republic of Ireland are the second most loyal, with the United Arab Emirates in third place.
Chile and Taiwan's business travellers, meanwhile, were named the least likely to return.
