Derriman was also president of the Institute of Public Relations from 1973 until 1974, and was awarded the President's Medallist of the IPR in 1978. He retired in 1982. His first book, "Pageantry of the Law" (1955), explained the origins and history of the ceremonial customs of English law and the traditional costumes of various law officers. His 1969 work, "Company–Investor Relations", detailed the correct procedures on dealing with the announcement of profit figures, takeover bids and shareholders' meetings. It was described as an excellent guide to the subject by Oliver Marriott in "The Times". He lived in Morden, Surrey.
