The inflation rate, which measures price changes, hit 2.3% in the year to October 2024, a bigger-than-expected increase from 1.7% in September 2024.
The increase was in part due to an increase in the regulator-set energy price cap that took effect in October 2024, which is expected to increase energy price inflation through the winter.
The Office for National Statistics (ONS), said while higher energy costs had contributed, this increase was offset by falls in live music and theatre ticket prices.
