Phillip was one of several Southwark MPs who were employed by the royal government in this period and is notable for having served both Henry VI and Edward IV as a serjeant-at-arms. It is likely that he was the ironmonger who was living in Southwark by October 1438, when an inn called The Falcon and certain shops and houses were leased to him by the feoffees of John Boteler for 16 years at an annual rent of five marks. That William Phillip, now described as an esquire, was apparently still residing in the neighbourhood in June 1454, when a tenement belonging to him was mentioned in an arbitration award.
Phillip received fees and livery as an esquire in the hall and chamber of the Household for over ten years from Michaelmas 1441,
Of Phillip’s career after this date little is known, and there is nothing to show that he was the man of this name who, a retainer of John Tiptoft, earl of Worcester, was granted the bailiwick of Haw and Tirley in Gloucestershire on 19 Apr. 1462, just five days after Tiptoft’s appointment as treasurer of England.
