On 26 November 2018, it was announced that Frost would be the next Dean of York, the head of the chapter of York Minster; his installation as Dean occurred on 2 February 2019. In March 2019, he was also licensed an honorary assistant bishop of the diocese, with a place in the diocesan House of Bishops.

It was announced on 30 July 2010 that Frost would become Bishop of Southampton in the Diocese of Winchester, succeeding Paul Butler (following Butler’s translation to Southwell). He was consecrated a bishop at St Paul’s Cathedral on 30 November 2010. He was welcomed to the Diocese of Winchester as Bishop of Southampton and installed as an honorary canon on 4 December 2010 at Winchester Cathedral.

His most recent posts prior to the episcopate, since 2002, were as Anglican chaplain to the University of Surrey and a canon residentiary at Guildford Cathedral. In 2007, he became co-ordinating chaplain at the university and was appointed the Bishop of Guildford’s Advisor for Inter-Faith Relations.

Frost was ordained a deacon on 27 June 1993, by Patrick Harris, Bishop of Southwell, at Southwell Minster — directly before he began his curacy at West Bridgford — and then a priest on 2 July 1994 at St John’s, Beeston, again by Harris. In 1994, alongside his curacy, he became a police chaplain until he moved on from both posts in 1997 when he became Rector of Ash until 2002. Frost also served on the General Synod during the 2005–2010 session.
