As the younger son of a leading Somerset family, Berkeley accompanied his elder brother Maurice to Oxford at an early age, and afterwards took up a military career in Ireland with his younger brother, Francis, who settled there. On his father’s death in 1601 he received £40 p.a. until the latter’s debts had been paid, whereupon he inherited the manor of Yarlington, ‘adorned ... with a handsome house’.
At the next general election, in 1628, Phelips hoped not only to regain his seat but to bring in Berkeley as ‘an honest, faithful countryman’; but they were unsuccessful.
An active royalist, he was briefly imprisoned in 1646 for hiring someone to impersonate him in taking the National Covenant, and he compounded at a fine of £1,187.
