Pye was returned for Brecon following the decision of his father, the chief justice of the Brecon circuit, to opt to sit for Herefordshire. He was married a fortnight later, and left no trace of his activities on the records of the third Caroline Parliament. In 1635 he inherited substantial property from his father, but the burden of the purchases already set in train, the expense of his father’s funeral and the cost of providing for his sister’s portions seem to have been to much for the estate to bear and Pye was forced to sell £4,780 worth of land and timber in the late 1630s. Nevertheless he was still one of the wealthiest landowners in Herefordshire at the outbreak of the Civil War.
He sat for Herefordshire in the Short Parliament and was in Rome in March 1642, where he engaged in political discussions with Cardinal Barberini.
