FX.co ★ UK CPIH Inflation Accelerates to 3.3% Year-on-Year, Ending Recent Cooling Trend

The United Kingdom’s CPIH inflation rate has risen to 3.3% year-on-year, according to data updated on 16 September 2026, marking an uptick from the previous reading of 2.8%. The CPIH measure, which includes owner occupiers’ housing costs, indicates that price pressures in the UK economy have strengthened compared with the same month a year earlier.

The latest figure breaks the recent pattern of easing inflation, as the previous month’s 2.8% print had signalled a modest cooling. Both the current and previous indicators are measured on a year-over-year basis, comparing price changes in each month to the corresponding month of the prior year. The move from 2.8% to 3.3% suggests that underlying price growth has picked up, potentially complicating the outlook for monetary policy and real household incomes in the months ahead.
