He was educated at Westminster School and Christ Church, Oxford, graduating B.A. in 1609. He was a Fellow of All Souls College, Oxford in 1612, and Vice-Chancellor of the University of Oxford in 1632. He became chaplain to Edward Sackville, 4th Earl of Dorset, who as his patron helped him become Dean of Christ Church.
He was chaplain to Charles I from 1634, and tutor to his two sons. He was regarded as a follower of William Laud. He was involved in the approval by Charles I of the manuscript of Eikon Basilike, reading it to the King in Carisbrooke Castle.
Duppa was made Bishop of Chichester (1638). From two years later (marking the start of the Civil War) until death he lived much more quietly at Richmond, (as Bishop of Salisbury from 1641), one the few Anglican bishops to remain in office during the English Interregnum.
A hill and a park bear his name given mostly to sports fields: Bishop Duppas Park in Lower Halliford, Shepperton, Surrey and seemingly Duppas Hill in Waddon, Croydon, London reflecting his influence on the previously ecclesiastical property.
Two sets of Bishop Duppa's almshouses were erected with his funds or endowed with his lands, one with original components, and one a 19th-century successor development:
- Duppa's Almshouses, Pembridge, Herefordshire
- Bishop Duppa's Almshouses, Richmond, now owned by Richmond Charities.
