The Office for National Statistics figures show that overseas visitors to the UK spent £2.5bn in July, a 4% rise on the same month last year.
The figures also show that it was a record July for inbound visits from EU countries, the UK’s largest visit-generating region, with 2.3 million visits, up 3% on last year.
There was also strong growth from North America, which includes the US – the UK’s most valuable visitor market – with visits up 5% to 580,000.
Visits from the ‘rest of the world’, which includes Australia, China, the Gulf markets and India, were up 6% to 790,000.
Tourism minister Tracey Crouch said: "Britain is a world-class visitor destination with our stunning countryside, historic buildings and vibrant culture scene attracting a record number of visits from around the globe.
“Tourism makes an enormous contribution to our economy and we will continue to support the industry to ensure it thrives and that growth in the sector benefits the whole country."
VisitBritain/VisitEngland chief executive Sally Balcombe said that the best-ever July figures underpinned a record-breaking first half year for inbound tourism, one of the UK’s fastest growing export industries.
“We want Britain to be top of people’s list as a ‘must-go now’ destination and we have an immediate and real opportunity to promote Britain as a great value destination, particularly in our long-haul high spending markets such as China and the US.
“We are refreshing our successful global #OMGB ‘Britain, Home of Amazing Moments’ campaign with stunning content from across our nations and regions to inspire visitors to put Britain at the top of their ‘wish list’, and working with commercial partners across the travel industry to ensure that inspiration to visit is converted into bookings, boosting the economy and jobs across our nations and regions.”
