The number of business trips to the country also rose 12 per cent to an all-time February high of 750,000.
It follows a record 35.8m visits made to the UK in 2015, six million more than in 2010.
Tourism Minister David Evennett said: "This record-breaking start to the year shows that our fantastic array of attractions remain hugely popular with visitors from all over the world.
"There is so much to see and do across the whole of the UK and we are absolutely committed to encouraging tourists to see all the hidden gems we have to offer."
Britain could be set for another boost with The Queen’s 90th birthday, the arrival of US President Barack Obama, and the 400th anniversary of Shakespeare’s death all falling this month.
Interest from the East is continuing to buoy the sector, with the number of Chinese visitors rising 40 per cent in the first nine months of 2015 alone.
London has been named the most popular tourist destination in the world for the past two years running, with 18.8m visitors spending £13bn in the city in 2015.
