The Fat Duck restaurant group doubled its pre-tax profits to £2.3m for the 12 months to 2 June 2013, up from £1.15m the previous year.
SL6, which owns Heston Blumenthal's three Michelin-starred Bray restaurant the Fat Duck, saw sales increase from £11.2m to £12.8m in the same period, according to accounts filed at Companies House.
The Fat Duck group workforce dropped from 152 to 137 staff while the annual wage bill rose to £3.57m (2012: £3.45m). Blumenthal's Hind's Head pub, in Bray, is also in SL6's portfolio, as well as a number of other corporate entities.
The celebrity chef founded the Fat Duck in 1995 but he sold his stake in the group in 2008 to businessman Ronnie Lowenthal. He remains with the business as head chef.
