The Consumer Prices Index (CPI) was unchanged in the year to August 2015, that is, a 12-month rate of 0%, down from 0.1% in the year to July 2015.
Smaller increases to clothing prices on the month compared with a year ago was the main driver behind the slowdown to price level growth.
Lower prices at the pumps together with cheaper ferry fares also helped to suppress price growth.
Bucking the lower price trend were soft drinks and furniture prices which helped prevent the UK from entering negative inflation again.
The UK entered negative inflation in April for the first time in 55 years.
