Lacey was educated at University College, Oxford, where he was a mature commoner, then Fellow, and subsequently Master of the College from 1398 until around 1401. The College prospered and developed under him, as well as under John Appleton and John Castell who followed him.
Around 1414, Lacey was appointed Dean of the Chapel Royal, accompanying King Henry V to the Battle of Agincourt in 1415. He was elected to the see of Hereford between 21 January and 17 February 1417 and consecrated on 18 April 1417. He was then translated to the see of Exeter on 15 July 1420. While bishop at Exeter, Lacey promoted the cult of the Archangel Raphael, proclaiming the feast in his diocese in 1443, and working throughout England to institute the cult.
Lacey died on 18 September 1455.
