De Ufford was the chancellor to Edward III, keeper of both the great seal and the privy seal. He was entrusted with the privy seal in 1342 (thus becoming Lord Privy Seal), and the great seal on 26 October 1345, which was the duty of the Lord Chancellor. He resigned the office of Lord Privy Seal after 29 September 1344, but held the office of Chancellor until his death.
