List of largest private companies in the United Kingdom

This is a list of largest private companies in the United Kingdom according to sales. Under UK company law, a private company (with the suffix "Ltd" usually) may not offer its shares for sale to the public (as can a "plc"). While lists of public companies usually rank businesses according to their market capitalisation (the traded share price multiplied by the number of shares), lists of private companies must use another measure, such as the value and volume of sales during a year.

Largest private companies

The following list is taken from the Sunday Times "Top Track 100", published on 24 June 2012.

Former private companies

Former members of the largest 100 private companies in the UK could have ceased to remain on the list for three main reasons. They may have (1) converted into a public company (like those on the FTSE 100, listed with the London Stock Exchange), or (2) have seen a decline in sales, or at worst (3) gone into an insolvency procedure, been sold, broken up, or liquidated.
