As a baron of Hastings, Carpenter could claim exemption from parliamentary taxation on his moveable goods outside the liberty, doing so from Henry IV’s reign through to 1449. These claims indicate that he held land at a number of places near Hastings, including Bexley, Wilting, Ore, Guestling and Crowhurst.
Carpenter had probably taken some part in the government of Hastings before his elections to the consecutive Parliaments of 1429 and 1431, although the evidence is wanting. In between those two returns, in May 1430, he was associated with William Prestwick, the clerk of the Parliaments, and John Faukes (later to be a successor to Prestwick) when John Parker I* of Hastings conveyed to them and others all his goods and chattels.
Carpenter was elected bailiff of Hastings in or before the spring of 1432, and as an MP for the third time five years later. He was one of three men of Hastings put forward at the Brodhull of July 1439 to be bailiff at the Yarmouth herring fair that autumn, but which of the three actually served does not appear in the records.
