The Office for National Statistics (ONS) revealed the increase, from 10.1% in September, as the cost of light and heating for homes rose further despite help from the government’s energy price guarantee that limits wholesale charges for gas and power.
Food was cited as the other major element adding inflationary pressure during October, rising at the fastest annual pace since 1977.
The ONS estimated that the 11.1% reading for the consumer prices index (CPI) measure of inflation was the highest since October 1981.
