Inflation was unchanged at 0.6% last month as rising food and transport prices were offset by a slip in the cost of clothing, wine and hotels.
The Consumer Price Index (CPI) inflation stalled in August after stepping up in June and July by 0.5% and 0.6% respectively, the Office for National Statistics (ONS) said.
Economists had been pencilling in a rise of 0.7%.
The ONS said there was “little sign” of the plunge in the value of the pound to 31-year lows following the Brexit vote being passed through to consumer prices.
However, the Producer Prices Index was impacted by the sterling’s slump, with input prices rising 7.6% in the year to August and imported material prices climbing by 9.3% over the period.
The fall in the value of the pound makes British goods cheaper to export on the global market, but makes imported goods and products more expensive.
The Retail Prices Index (RPI) – a separate measure of inflation, which includes housing costs – fell to 1.8% in August, down from 1.9% in July.
