Most Muslim communities appoint one person to make funeral arrangements. It will be up to them to advise of the rules and to select a suitable funeral director.
Hindus are always cremated. There are many possible variations of rites, depending on the form of Hinduism. The Asian Funeral Service can give advice on and arrange Hindu funerals. It can be contacted on 020 8909 3737 or firstname.lastname@example.org
Jewish funerals are usually arranged by a dedicated Jewish Funeral Agency or the local community may have a contract with a Gentile funeral service which will be carried out under strict Rabbinical control. The Jewish Bereavement Counselling Service offers support and can be contacted on 020 8349 0839.
