In November 1937 he joined the Home Office as an Assistant Principal. In World War II he served in the Rifle Brigade from 1942 to 1945, rising to the rank of Major.
Hayman was director general of the British Information Services in New York (1961–64) and then deputy commandant of the British military government in West Berlin from 1964 to 1966. He returned to the Foreign and Commonwealth Office, becoming Deputy Under Secretary of State with responsibility for the United Nations and Eastern Europe from 1969 to 1970. Then, from 1970 to 1974, he served as High Commissioner of the United Kingdom to Canada.
The Independent stated in his obituary that he started a commercial career in 1974, upon retirement at age 60. However The Guardian reported in 2014 that he later served in the intelligence services, and was "long-time deputy director of MI6". The Daily Telegraph characterized him as an "MI6 operative".
In October 1978, Hayman left a package of paedophilia-related materials on a London bus. The police traced the package and discovered that under the pseudonym "Peter Henderson", Hayman had used an apartment in Bayswater, London, to conduct obscene correspondence. In the apartment, police found 45 diaries describing six years of "sexual fantasies" concerning children and activities with prostitutes, articles of female clothing and obscene literature. He was investigated by police but released without charge after being given a warning not to send obscene material through the mail. In 1981, Private Eye magazine revealed this event. Then, using parliamentary privilege, MP Geoffrey Dickens asked why Hayman had not been prosecuted. The Attorney General's reply indicated that while Hayman had been found to have received pornographic material through the post, it was not of an extreme nature, was non-commercial and in a sealed envelope, so did not warrant prosecution.
In April 1981 Sir Michael Havers, the Attorney General, said in parliament that while Hayman was a member of the Paedophile Information Exchange, he was never a member of the executive committee, so was not prosecuted as others were for publishing contact advertisements.
In 1984, Hayman was convicted for an act of gross indecency in a public lavatory.
Later, on 29 November 1985, Dickens complained in the House of Commons that he had suffered harassment following his naming of Hayman. "The noose around my neck grew tighter after I named a former high-flying British diplomat on the Floor of the House. Honourable Members will understand that where big money is involved and as important names came into my possession so the threats began. First, I received threatening telephone calls followed by two burglaries at my London home. Then, more seriously, my name appeared on a multi-killer's hit list." The Independent newspaper in February 2013 could find no corroboration for Dickens' claims in 1985.

A teenage boy working at Buckingham Palace revealed he was groomed and sexually abused by a VIP paedophile ring there. The lad was also assaulted at the Royal Family’s Scottish retreat Balmoral, according to shocking Home Office files, reports the Sunday People. The boy who was 16 at the time, told how he was the victim of “exploitation of the highest order” – the claims could now be the subject of a police investigation.
The boy who was 16 at the time, told how he was the victim of “exploitation of the highest order” – the claims could now be the subject of a police investigation. In a heartbreaking note, the boy – then just 16 – told how he was the victim of “exploitation of the highest order”. The chilling claims could now be the subject of a police investigation into historic allegations of child sex abuse in the 1970s and 80s – linked to MPs and powerful figures. The disturbing account was passed directly to the then Home Secretary Leon Brittan but he ruled it was “not practical” to investigate. Campaigning Labour MP Tom Watson said: “I’m sure the Palace will want to co-operate with any inquiry.” A Palace spokesman said: “The Royal Household takes any allegation of this nature seriously and would act to address any specific allegations or investigate specific information.” The Sunday People and the investigations website Exaro have established that the Home Office file contains evidence of a letter written by the boy’s mother.
