Skirlaw was employed on diplomatic missions to Italy in 1381–3,[9] to Calais to negotiate with the French in 1388,[10] and to the Scots. He died on 24 March 1406.[6]: 242
Skirlaw is described as "a munificent prelate. He built bridges at Shincliffe, Bishop Auckland, and Yarm; a refuge tower, a beautiful chapter-house (now in ruins) at Howden; and was a large contributor to the expense of building the central tower of York Cathedral".[11]
