British inflation climbed to 2.9% in July, up from 2.6% in June, hitting its highest level since March. The culprit is familiar: energy bills, which spiked after Ofgem raised its price cap by 13% at the start of the month.

The data, published by the Office for National Statistics on August 19, landed exactly where markets expected it. That doesn’t make it any more comfortable for households watching their gas bills climb by 14.7%, the steepest increase since October 2022.

What’s driving the numbers

Core CPI, which strips out volatile items like energy and food, held steady at 2.6%. The broader measure of inflation, CPIH, which includes owner-occupiers’ housing costs, rose to 3.1% from 2.8% the prior month.

Global energy markets have been rattled by geopolitical tensions, particularly the US-Israel conflict with Iran, which has kept oil and gas prices elevated.
