The energy price cap – which limits what can be charged per unit of energy – is due to fall from the month after next.
It means the average annual bill will be £1,568 a year, 7% less than at present.
But while the July figure is a reduction, bills are still more expensive than before.
Before the energy price shock, caused primarily by Russia's invasion of Ukraine in February 2022, a standard 12-monthly bill was £1,084.

So compared with three years ago, energy is costing homes an extra £484.
During the current period from 1 April to 30 June, the energy price cap is set at £1,690 per year for a typical bill.
Energy regulator Ofgem sets the cap four times a year, with the latest announcement applying from July to September.
The overall rate of inflation came down in April – in large part thanks to the current higher cap which came into effect that month and brought prices down for energy users, according to the Office for National Statistics.

"People cannot rely on lower energy prices alone to escape the financial issues they've been experiencing. That's why we need better targeted energy bill support for those really struggling to keep the lights on or cook a hot meal."
More expense to come
