He played the recurring character Mr. (Sidney) Bluett in Dad's Army from 1969 to 1977, but it was as Young Mr. Grace, the ancient, amiably callous owner of Grace Brothers department store in British sitcom Are You Being Served? that he achieved his greatest fame. His last appearance in Are You Being Served aired some three months after his death, having been filmed earlier in the year.
Bennett also played the role of the aged Archdeacon Pulteney in The Stalls of Barchester, the 1971 BBC A Ghost Story for Christmas broadcast 24 December 1971 and adapted from the M.R. James story of the same name. Bennett appeared in several films, including an old man in Vote, Vote, Vote for Nigel Barton (1965), a Photographer in Games That Lovers Play (1970) and as Lord Tryke in The Ups and Downs of a Handyman (1975).
Harold Bennett died of a heart attack on 15 September 1981, two days before his 83rd birthday. His wife predeceased him in the Thirties; he was survived by their three children. One of his children, John, was also an actor.
