Howard was the son of Charles, 2nd Lord Howard of Effingham. His father, who twice represented Surrey before succeeding to the peerage, was lord admiral from 1585 to 1619, lord lieutenant of Surrey and Sussex and created earl of Nottingham in 1597. Howard himself had already sat for Surrey and Sussex in the late Elizabethan period. In January 1604 his elder brother, Sir William Howard†, was summoned to the Lords. This left Howard as the senior member of the family eligible to sit in the Commons and therefore, presumably, the primary focus of his father’s electoral patronage.
Howard’s marriage in 1597 to the widow of a successful ironmaster had brought him three Sussex manors: he subsequently resided in the county, at the time of his knighthood in 1603 at Sheffield in the parish of Fletching, eight miles north of Lewes.
Howard left no mark on the records of the 1604-10 Parliament, taking no apparent interest even in the controversial bill introduced in May 1604 to provide for his sister, the dowager countess of Kildare.
In 1614 Howard, by now vice-admiral of Sussex, sat for the maritime borough of New Shoreham, where his father had long exercised electoral patronage.
In 1606 Howard received a further pension of £300 on surrendering the keepership of Windsor Great Park.
Perhaps hoping that, like his elder brother, he would be summoned to the Lords in his father’s lifetime, Howard appears not to have sought re-election in the early 1620s. Nevertheless in 1621 and 1624 he petitioned the Commons to reverse Cranfield’s decree.
Summoned to attend the king at York in 1639, Howard pleaded ill health and poverty, claiming an income of less than £400.
