Born in Hertford Street in London's district Mayfair, he was the eldest son of John Peter Boileau and his wife Henrietta, the eldest daughter of John Pollen. His family claimed descendancy of Étienne Boileau, one of the first known provosts of Paris. He was educated at Eton College and went then to Merton College, Oxford. In 1813, Boileau joined the British Army and was commissioned as 2nd lieutenant into the Rifle Corps, which his uncle Coote Manningham had established. After four years service, he was put on halfpay in 1817. He bought an estate in Ketteringham in 1836, which he later expanded with a Gothic hall.
In 1838, Boileau was created a baronet, of Tacolnestone Hall, in the County of Norfolk. He was elected a fellow of the Royal Society in 1843 and was appointed High Sheriff of Norfolk in 1844. When one year later the Norfolk and Norwich Archaeological Society was founded, Boileau was nominated one of its vice-presidents until 1849, after which he became the Society's president. He joined the Society of Antiquaries of London in 1852 and by the recommendation of Philip Stanhope, 5th Earl Stanhope, he was chosen a vice-president in 1858, a post he occupied for seven years with only a break in 1863. Boileau was additionally vice-president of the Zoological Society of London and of the Royal Statistical Society. He served in the same capacity for the Institute of Archaeology and for the Royal Society of Arts. Boileau further held a fellowship in the Geological Society of London and was vice-president of the Royal Institution as well as the British Science Association. He represented Norfolk both as a Deputy Lieutenant as well as a Justice of the Peace.
In 1825, he married Catherine Sarah, the third daughter of Gilbert Elliot-Murray-Kynynmound, 1st Earl of Minto. They had four sons and five daughters. His wife died in 1862 and Boileau survived her until 1869, having suffered on chronic bronchitis in his last years. He died at Torquay and was buried in the family's vault in Ketteringham. His oldest son John having predeceased him in 1861, he was succeeded in the baronetcy by his second son Francis.
