Surviving letters from the precentor of Chichester Cathedral beg the bishop to come to Chichester over Easter to celebrate the Easter Mass and to deal with pressing issues in the diocese. Neville's duties as chancellor kept him from attending to much of the business of his diocese, but he employed clerics to administer the ecclesiastical offices of his diocese and in general his relationship with his cathedral chapter appears to have been good. He employed a teacher of theology for his cathedral, and supported students at schools in Lincoln, Oxford, and Douai. He worked to protect the rights, lands, and privileges of his diocese and cathedral chapter from encroachment by others, both secular and clerical. On one occasion he threatened to excommunicate the Earl of Arundel or the earl's men for hunting on land the bishop considered to be his own.
