On 1 October 1981, British Telecommunications, trading as British Telecom, finally severed its links with the Post Office and became a totally separate public corporation under the provisions of the British Telecommunications Act, 1981.

It was also at this time that the first steps were taken to introduce competition into the United Kingdom telecommunications industry: British Telecom lost its monopoly of the supply of customer premises equipment and the Secretary of State for Trade and Industry was empowered to grant licences to operators other than British Telecom to provide network and value added services.

In 1982, Mercury Communications Ltd was licensed as the main competitor to British Telecom and, on 19 July 1982, the Government formally announced its intention to sell up to 51% of British Telecom to the public: the first example of the privatisation of a public utility. The transfer to British Telecommunications plc from British Telecom as a statutory corporation of its business, its property, its rights and liabilities took place on 6 August 1984.
