MANUFACTURERS struggled to pass on higher fuel prices last month.
Although raw material prices rose by more than expected in November after a pick-up in fuel costs, the amount charged by manufacturers for their goods fell by 0.2%.
The Office for National Statistics said it contributed to annual output prices rising 2.3% in the year to November.
This was the lowest annual rate of increase since April last year.
Experts said the data showed manufacturers' margins appeared to be under "significant" pressure.
Thushani Gajasinghe, economist at the Centre of Economics and Business Research, said the news highlighted that high oil prices were putting a strain on manufacturers.
She said: "With input prices continuing to rise, we may see the effects feeding through into output prices in the coming months. We expect that the Bank of England will continue to hold interest rates at their current rate, but they will need to keep a close eye on inflation."
