Britnell was a fast track graduate of the NHS's training scheme and was one of the youngest ever chief executives in the health service. He spent six years as the head of University Hospital Birmingham, helped develop the NHS Plan - a ten year plan for investment and reform, became CEO for the NHS region between Oxford and the Isle of Wight and was director general at the Department of Health, where he also sat on the NHS management board for three years.
In 2009 he began his role with KPMG. The role was approved by ACOBA 'subject to a waiting period of three months from his last day of service and the condition that, for 12 months from the same date, he should not be personally involved in lobbying UK Ministers or Crown servants, including Special Advisers, on behalf of KPMG'.
