The news will be of concern for those hoping that the Bank of England will stay its hand in raising interest rates again this year.
Some financial commentators had begun to suggest that the three interest rate rises in the five months to January might have been enough to push consumer price index inflation back down to the chancellor's target of two per cent from its current 2.8 per cent.
But others have continued to argue that a further hike from the current base rate of 5.25 per cent will be required. Today's factory gate figures reinforce their position.
More likely to be decisive in deciding the monetary policy committee's new stance will be tomorrow's CPI inflation statistic from the Bank.
An increase would almost seal the widely-expected hike from the MPC in May's decision.
