Scientology in the United Kingdom is practised mainly within the Church of Scientology and its related groups which go under names including "Hubbard Academy of Personal Independence" and "Dianetics and Scientology Life Improvement Centre".
 The national headquarters, and former global headquarters, is Saint Hill Manor at East Grinstead, which for seven years was the home of L. Ron Hubbard, the pulp fiction author who created Scientology.
 Church-connected groups promoting aspects of L. Ron Hubbard's teaching, including Narconon and CCHR, have also been active in the UK, in some cases with charitable status.
 There have also been groups practising Scientology independently of the Church.
Brain-Washing: A Synthesis of the Russian Textbook on Psychopolitics, sometimes referred to as The Brainwashing Manual, is a book published by the Church of Scientology in 1955.
 It purports to be a condensation of the work of Lavrentiy Beria, the Soviet secret police chief.
 The book states Kenneth Goff as author.
 Its true authorship is not clear, the three common hypotheses being: Scientology founder L Ron Hubbard, Kenneth Goff (alias Oliver Kenneth Goff), or both L Ron Hubbard and Kenneth Goff based on an acquired US agency report.
 The third hypothesis is questionable as there is not proof that the two men ever knew each other.
 Claims that L Ron Hubbard was the author are also dubious as the only source of this claim is his estranged son, L Ron Hubbard Jr., who made it his life work trying to intentionally discredit his father in every possible way, and in addition to withdrawing all his accusations before his death, has been discredited in courts of law.

Lafayette Ronald Hubbard (March 13, 1911 – January 24, 1986), better known as L. Ron Hubbard ( ) and often referred to by his initials, LRH, was an American author and the founder of the Church of Scientology.
 After establishing a career as a writer, becoming best known for his science fiction and fantasy stories, he developed a system called Dianetics which was first expounded in book form in May 1950.
 He subsequently developed his ideas into a wide-ranging set of doctrines and practices as part of a new religious movement that he called Scientology.
 His writings became the guiding texts for the Church of Scientology and a number of affiliated organizations that address such diverse topics as business administration, literacy and drug rehabilitation.
 The Church's dissemination of these materials led to Hubbard being listed by the "Guinness Book of World Records" as the most translated and published author in the world.
 The Guinness World Record for the most audio books published for one author is also held by Hubbard.
 In 2014, Hubbard was cited by "Smithsonian" magazine as one of the 100 most significant Americans of all time, as one of the eleven religious figures on that list.
