The release from the Office for National Statistics (ONS) revealed Consumer Prices Index (CPI) inflation fell from 1.5% in August to 1.2% in September, well below the dip to 1.4% which was expected.
The ONS said a combination of falls in transport costs (notably sea and air fares) and prices for a range of recreational goods helped drive down the headline figure sharply.
This latest drop also bolsters the case for the Bank of England’s Monetary Policy Committee to hold off on raising interest rates, appearing to take a 2014 hike off the table for now.
September’s figure is the lowest rate of inflation since September 2009, when CPI stood at 1.1%.
The ONS said if falling food and motor fuel prices were excluded, inflation would be a third higher thanks to soaring utility bills.
Meanwhile RPI dropped from 2.4% to 2.3%, in line with expectations the ONS said.
