Annual inflation had stood at a year-low of 2.2 percent in October, the Office for National Statistics (ONS) said in a statement.
"The Consumer Prices Index (CPI) grew by 2.1 percent in the year to November 2013, down from 2.2 percent in October," the ONS said.
"The largest contributions to the fall in the rate came from food and the utilities -- gas and electricity. These were partially offset by upward contributions from the transport sector and from some aspects of recreation and culture," it added.
At 2.1 percent, the rate was the lowest level since November 2009.
The Bank of England's main task is to use monetary policy as a tool to keep annual inflation close to a government-set target of 2.0 percent, in order to preserve the value of money.
The annual CPI rate has held above this target level since November 2009 but has dropped from a level of more than five percent in the space of two years.
