He was appointed by the Long Parliament to be one of the commissioners to carry the propositions for peace to Charles at Oxford in 1643 and was also a commissioner for the Treaty of Uxbridge in 1645 and the Treaty of Newport in 1648. In 1645 he was granted £4 a week by Parliament for damages caused by the King's forces at his Oxfordshire estate.

Lord Wenman married Margaret, daughter of Edmund Hampden. He died without surviving male issue in January 1665 and was succeeded by his younger brother, Philip.
