Colet was trading in woollen cloth at Wallingford from 1394 until at least 1402. There is no actual record of his residing there, but it is clear that he was a burgess of that town, for he held the minor office of bridge warden in 1397-8 and, in the following year, sat as a juror in the borough court. He first appears in the Oxford records as standing surety for John Spicer I’s attendance in the 1399 Parliament, and five years later he became one of the borough’s chamberlains. The last record connecting Colet with Wallingford occurs in 1407, when he went surety for the attendance of William Clowd in Parliament.
Colet’s property in Oxford included two houses in All Saints’ parish. He witnessed deeds there in 1407 and 1408, and served as bailiff in 1409-10.
