Spicer entered the freedom of Lynn on 4 Nov. 1384 on completion of his apprenticeship to the enterprising merchant, John Brandon, and six years later he was living in St. James’s Street. From 1410 he leased from the Holy Trinity guild six cellars (three of them rent-free), and shortly after, for £1 annually, he was granted ‘le Feryryght’ by the authorities.
By 1390 Spicer had established a friendship with another of the potentiores, Thomas Brigge, and in 1392 he joined him on the body of jurats responsible for governing the town. In July 1402 he was included among a number of burgesses each of whom was required to provide securities in £100 before the sheriff of Norfolk to keep the peace towards their overlord, Bishop Despenser of Norwich. Although he was appointed in December 1411 as one of the 18 arbitrators assigned to settle the current disputes about Lynn’s constitution, Spicer did not find the opposition party’s control of the town acceptable, and in the following year he was removed from the bench. Then, on the night of 20 Aug. 1414, immediately after his reinstatement, he and other potentiores were assaulted by William Halyate and his followers when on their way home from a local tavern.
