After leaving university in 1973, he joined Barclays Bank and served in a number of managerial and senior managerial posts in London and in other countries. After succeeding his second cousin as 7th Earl Howe in 1984, he left banking to concentrate on his Parliamentary activities and on running the family farm (Seagraves Farm Co Ltd) and estate at Penn in south Buckinghamshire. In 1991, Howe became a Lord in Waiting (Government whip in the House of Lords) with responsibilities, successively, for transport, employment, defence and environment. Following the 1992 general election he was appointed Parliamentary Secretary at the Ministry of Agriculture, Fisheries and Food and in 1995 Parliamentary Under-Secretary of State at the Ministry of Defence, a post he relinquished at the 1997 general election.
