Energy Bills Up 19 Percent in a Year and Households Are Feeling It

New inflation data published Tuesday shows energy costs have surged nearly a fifth in twelve months, piling fresh pressure onto budgets already stretched by three years of elevated prices.

Energy prices rose 19% in the year to July 2026, according to the latest Retail Prices Indices and Household Costs Indices data.
The figures were published Tuesday as part of the UK's routine monthly inflation release.
The jump marks one of the steeper annual energy readings since the post-pandemic price spike cycle began.
Household Costs Indices, which weight spending by how much households actually buy, tend to show sharper energy impacts than headline CPI figures.
The data lands as summer usage is typically low, raising concern about what autumn and winter bills will look like.

It is the middle of summer, when boilers sit idle and the heating debate is months away — and yet Tuesday's inflation release landed with the kind of number that tends to get screenshot and sent to a group chat. Energy prices are up 19 percent over the past year, according to Retail Prices Indices and Household Costs Indices data published this morning.

The figures come from the UK's standard monthly statistical release, and 19 percent is not a typo. It is the kind of annual movement that, a decade ago, would have cleared the front page on its own. After the extraordinary volatility of 2022 and 2023, it lands instead as the latest chapter in a stretch of elevated energy costs that has quietly restructured how a large slice of households think about direct debits.

The Household Costs Indices are worth watching separately from the headline consumer price measures. They weight expenditure by what people actually spend rather than a theoretical basket, which means energy — something households cannot easily cut — tends to punch harder in the final number. For renters and lower-income households especially, the 19 percent figure tracks closer to lived experience than the broader index.

With summer usage at its seasonal floor, suppliers are already signalling that the autumn price cap review will be the one to watch. The next Ofgem determination is due before the season turns — and on current trajectory, the number published today will not be the last one that gets shared around.
