The tenth annual Sunday Times Grant Thornton Top Track 250 league table supplement was published on 12 October 2014, with title sponsor Grant Thornton.

The Sunday Times Grant Thornton Top Track 250 is the sister publication of The Sunday Times Top Track 100, which identifies Britain's 100 private companies with the biggest sales. The league table ranks the 250 next biggest private companies, provided either sales or operating profits have increased by at least 10% in their latest available accounts. Sales range from £140m to £650m.

Despite the tough economy, two thirds of the companies on the league table improved their operating profit margin in their latest year, and 95% increased their sales to a combined £70bn, equivalent to 4% of GDP. Staff numbers are up 36,000 from the previous year to 412,000, representing 1.3% of the UK workforce.

Domestic & General is the top company with sales of £633m. The warranty provider protects 22m household appliances in 12 countries. Private equity firm CVC Capital Partners bought the London-based company from Advent for a reported £750m in 2013. Other well-known names include Aston Martin, Barbour, Dr Martens, Jeyes, Nando’s, Pret A Manger, Warburtons, and Yeo Valley. See the press releases.

The 2015 Sunday Times Grant Thornton Top Track 250 league table will be published on 11 October.
