Reddaway was born in Ottawa, Ontario, Canada, where his father, Norman Reddaway, also a British diplomat, was posted at the time. He attended King's College School, Cambridge and Oundle School, then studied History at Fitzwilliam College, Cambridge, where his grandfather, the historian William Fiddian Reddaway, had served as Censor. He then joined the Foreign and Commonwealth Office in 1975. His career has included assignments to Iran (during the Iranian revolution), India, Spain, Argentina and Afghanistan. Married to Roshan, he is the father of three.
In 2002, his appointment as British ambassador to Iran was rejected by the Iranian government, with some Iranian newspapers (incorrectly) accusing him of being "a Jew and a member of MI6". He speaks fluent Persian and his wife is Iranian.
He served as High Commissioner to Canada between 2003 and 2006. In 2006 he was appointed the British ambassador to Ireland and presented his diplomatic credentials to the President of Ireland, Mary McAleese on 12 September 2006, succeeding Stewart Eldon as British ambassador to Ireland.
Reddaway was appointed MBE in the Queen's Birthday Honours of 1980, CMG in 1993, and knighted KCMG in the 2013 Birthday Honours "for services to British diplomacy and furthering UK interests in Turkey".
