Shaftesbury said that, with its variety and quality of attractions, coupled with a large and important local working population, London's West End continues to attract large numbers of visitors, both domestic and from overseas.
"Trading across our shops, restaurants, cafes and bars has been good throughout the summer months and, with sustained tenant demand across all uses and in each of our locations, available-to-let vacancy remains low," the company said in a statement.
"London's global status and its importance as the largest city in Western Europe underpin its long-term prospects.
"The West End, with its exceptional choice of world-class attractions, shopping and innovative, accessible dining and leisure options, is a major draw for visitors and an important location for domestic and international businesses.
"Although the referendum vote to leave the European Union may create a period of uncertainty for businesses until new trading and other arrangements are negotiated, to date we have seen no adverse impact on occupier demand, footfall or trading."
