Factory gate prices for UK-manufactured goods increased 3.7% year-on-year in August 2026, accelerating from an upwardly revised 3.3% rise in July, which was the softest increase in four months, and surpassing expectations of 3.3% to mark the fastest increase in three months. Eight of the 10 product groups made upward contributions to the annual rate, led by a jump in prices of coke and refined petroleum products (49.1% vs. 35.4% in July) amid higher energy costs. On a monthly basis, factory gate prices rose 0.7%, after an upwardly revised 0.4% gain in July and above market forecasts of 0.3%.
