UK producer prices, or the cost of goods at the factory gate, increased by 0.2% in July from June, the latest data shows. On a 12-month basis output prices rose by 2.8%, the Office for National Statistics said.
The data undershot analysts' consensus forecast for a 0.4% month-on-month rise and a yearly increase of 2.9%.
Producer prices were pushed higher by soaring crude oil prices in July, but manufacturers struggled to pass on the increased costs.
Input costs, or the cost of raw materials to industry, rose by 1.1% in July from June. Input prices climbed by 9.6% on a year-on-year basis, the ONS added.
