text: 1989 "Beer Orders" During the prime ministership of Margaret Thatcher, beer production, distribution and retailing were vertically integrated, with the "Big Six" brewers (Bass among them) accounting for a large portion of UK beer production and sales. Most pubs were "tied houses", owned by one of the brewers, and mostly selling its products.
  On the advice of the Director-General of Fair Trading, the Monopolies and Mergers Commission (later the Competition Commission) released a report entitled "The Supply of Beer: A Report on the Supply of Beer for Retail Sale in the United Kingdom", investigating the nature of the beer industry. The report made recommendations to break up a "complex monopoly" among beer brewing and sales between the UK's "Big Six" (Allied, Bass, Courage, Grand Metropolitan, Scottish & Newcastle, and Whitbread), which at that time accounted for "75% of beer production, 74% of the brewer-owned retail estate, and 86% of loan ties." Recommendations to limit the number of pubs a brewing company could own were enacted in legislation in 1989, commonly called "the Beer Orders", with three years for brewers to dispose of excess pubs. Bass went from owning approximately 7,190 pubs in 1989 to about 2,077 in 2014 (by its successor company Mitchells & Butlers).
