Lower electricity and gas bills help drive down the overall rate of inflation to a 15-month low with the consumer prices index (CPI) rate dipping to 3.4 per cent.
The drop comes as some economists warn that the overall rate of inflation may not pull back as quickly as previously thought amid resurgent oil prices, although the Office for National Statistics said there was no evidence of this in February.
Alternative measures of inflation also declined, with the retail prices index (RPI) dipping to 3.7 per cent in February, from 3.9 per cent in January.
The easing rate of inflation will be welcomed by households that were squeezed by high prices and sluggish wage growth throughout 2011 and will add further weight to the Bank’s decision to pump an extra £50bn into its quantitative easing programme last month.
Bank governor Sir Mervyn King and his colleagues have forecast the rate of inflation to dip below the government’s 2 per cent target at some point early next year.
The greatest downward pressure on the CPI rate came from domestic electricity and gas bills, which fell 1.3 per cent and 0.9 per cent respectively.

Elsewhere, alcohol prices rose 2.6 per cent, a record rise for a January-to-February period, but the ONS said this is a particularly volatile category and offered no specific reason for the rise.
