Ellis was educated at City Grammar School, Sheffield;^{[citation needed]} trained for the ministry at King's College London and^[8] at St Augustine's College, Canterbury; and took his Doctor of Philosophy (DPhil) at York University.^{[citation needed][when?]}

Ordained in 1977 he began his career with a curacy in Manchester^[9] at St John's Church, Old Trafford and was then successively Vicar at Pendleton; Vicar of St Leonard, Norwood, Sheffield; Rural Dean of Ecclesfield, also Canon of Sheffield Cathedral, and finally (before his ordination to the episcopate) Archdeacon of Stow and Lindsey in the Diocese of Lincoln.

A keen Sheffield Wednesday fan^[10] and occasional blogger,^[11] he is also believed to be the first bishop to sport an earring.^{[citation needed]}

Ellis is now honorary assistant bishop in the Sheffield and Derby dioceses.

On 11 February 2017, Ellis was one of fourteen retired bishops to sign an open letter to the then-serving bishops of the Church of England. In an unprecedented move, they expressed their opposition to the House of Bishops' report to General Synod on sexuality, which recommended no change to the church's canons or practises around sexuality.^[15] By 13 February, a serving bishop (Alan Wilson, Bishop of Buckingham) and nine further retired bishops had added their signatures;^[16] on 15 February, the report was rejected by synod.^[17]
