Warburtons overcame soaring energy and ingredients costs last year, to achieve a 20% rise in turnover for its full year to 27 September 2008, with distribution stated as the key driver of growth.

Its accounts, newly-filed at Companies House, revealed turnover stood at £498m, compared to £414m for the comparable period in 2007. This is despite a 41% hike in raw material and consumable costs. Profit before tax stood at £31.8m - up £5.5m on the previous period.

The firm said its results for 2008 were in line with expec-tations and that the board views the outcome as "satisfactory", in light of the economic climate.

Chairman Jonathan Warburton said the firm "will continue to grow share in the bread market by investing in the brand and business to ensure future success".
