Leveson matriculated at Queen's College, Oxford, on 10 January 1576, and studied for a time at Gray's Inn. According to Wisker, Leveson was an efficient estate manager and 'an excellent public servant'. He was a close associate in Kent of William Brooke, 10th Baron Cobham, and eventually one of the executors of his will. He was also a captain in Peregrine Bertie, 13th Baron Willoughby de Eresby's 1589 expedition to France. He was knighted in 1589, and helped raise volunteers for three of Sir John Norris's expeditions in 1589, 1596 and 1601. He was a cousin of Sir Richard Leveson, and with him was involved in the shipment of 2000 soldiers sent to Ireland in 1601. While riding to his house at the Blackfriars, London, on 8 February 1601 Leveson inadvertently became instrumental in suppressing the rebellion of Robert Devereux, 2nd Earl of Essex, taking command of a force on Ludgate Hill and placing a barrier across the street. Within half an hour Essex's men tried to force their way through, and in the resulting skirmish Essex's stepfather, Sir Christopher Blount was injured, whereupon Essex withdrew with his men to Essex House. Leveson was a Member of Parliament for Bossiney in 1586, Maidstone in 1597 and 1601, and for Kent in 1604. He died at Whornes Place on 14 November 1615, and was buried in the parish church at Cuxton on 22 November.

After Sir John Leveson's death, Frances married, as his first wife, Thomas Savile, later Earl of Sussex. There were no issue of the marriage. After Frances' death, Savile married secondly, shortly after November 1640, Anne Villiers, only daughter of Christopher Villiers, 1st Earl of Anglesey, by Elizabeth Sheldon, the daughter of Thomas Sheldon.
Richard Leveson. Richard was made heir to the large but heavily indebted Shropshire and Staffordshire estates of his relative and namesake, Vice-Admiral Richard Leveson, who died in 1605. Sir John was much concerned in his later years, as head of a family trust, with the struggle to rectify the financial position of the Leveson estates. He died with the issue unresolved but his wife, Christian, was able to pay off the debts and secure the inheritance of their second son in 1623.
