Fleetwood began his career in Ireland, possibly under the command of his brother-in-law, Sir Oliver Lambart†, and was knighted there by lord deputy Mountjoy in 1602. He was granted the reversion to the receiver-generalship of the Court of Wards in 1604 and entered into office six years later after his father, the former incumbent, was sequestered.
Fleetwood was returned to the Addled Parliament for Huntingdon on the interest of his wife’s uncle, the 3rd Lord St. John of Bletso, the county’s lord lieutenant.
In 1619, at the trial of the former lord treasurer, the earl of Suffolk, Fleetwood gave evidence that he had once paid £500 to Suffolk, ‘fearing his greatness and desirous to procure his favour’.
By March 1622 Fleetwood had attached himself to the royal favourite, George Villiers, marquess (and later duke) of Buckingham.
Fleetwood was returned to the first two Caroline Parliaments for Newton in Lancashire, a proprietary borough then in the hands of his Catholic cousin, Sir Richard Fleetwood of Colwich, Staffordshire and Penwortham in Lancashire.
In the Parliament of 1626 Fleetwood again demonstrated that while he zealously advocated the maintenance of religion at home and abroad, he was more open minded about the question of how to raise sufficient revenue. His numerous committee appointments included those for religion (10 Feb.), simony (14 Feb.) and unworthy clergymen (15 February). He was also among those ordered to present the names of dangerous recusants (23 Feb.) and to examine the procedure for naming committees (3 March).
Following the dissolution Fleetwood was summoned to appear before the newly appointed Crown revenue commissioners to provide information about pensions and annuities paid out of the Court of Wards. Like his father he was suspected of making irregular use of the sums passing through his office; however, no charges were brought against him.
Returned to the third Caroline Parliament for Woodstock, where his brother Sir Gerrard was keeper of the royal park, Fleetwood continued to attract numerous committee appointments, many of them concerned with measures against recusancy.
The breach of this Parliament will be the greatest misery that ever befell us. The eyes of Christendom are upon this Parliament. The fate of all our Protestant friends are ready to be swallowed up by the emperor’s forces, and our own kingdom is in a miserable strait. The defence of our religion, that is invaded by Romish Catholics by the colour of a commission which is intolerable; the defence of our realm by shipping is decayed; the king’s revenues are sold and gone.

He therefore favoured a bill to ‘establish the fundamental laws’. He was later named to attend a joint conference on the Petition of Right (20 June).
In the second session Fleetwood was among those appointed to consider bills against corruption in judicial and ecclesiastical appointments (23 Jan. 1629) and an explanatory recusancy bill (28 January).
Fleetwood was returned for Hindon to the Short Parliament in 1640, leaving the seat at Woodstock for his eldest son Sir William†. Walter Steward* reportedly said of Fleetwood that ‘he went to two sermons on a Sunday, and that on Monday morning he would sell his friend for two shillings’, but despite charges of corruption he retained the receivership of the Wards until his death.
