In 1614 he was High Sheriff of Essex. He was elected Member of Parliament for Harwich in 1614.

In 1626 Grimston was elected knight of the shire (MP) for Essex. He was re-elected in 1628 and held the seat to 1629 when King Charles decided to rule without parliament for eleven years. In April 1640 he was re-elected MP for Essex in the Short Parliament. In November 1640 he was elected MP for Harwich in the Long Parliament. He held the seat until his death in 1648.
