The average household energy bill in the UK is set to rise by 9% in October when the latest change to the energy price cap takes effect, according to experts.
Energy consultancy Cornwall Insight said it expects the typical household's energy bill to rise to £1,714 a year, up 9.3% from £1,568 currently, on October 1.
This is less than its previous prediction in June, when it estimated that the cap would rise by 9.9% to £1,723.
But the group said there is also likely to be a further "modest" increase in January 2025, with more rises possible early in the new year due to "recent tensions in the Russia-Ukraine war".
Energy regulator Ofgem will announce the energy price cap for October to December on Friday August 23.
Craig Lowrey, principal consultant at Cornwall Insight, said: "this is not the news households want to hear when moving into the colder months.
"Following two consecutive falls in the cap, I'm sure many hoped we were on a steady path back to pre-crisis prices.
"However, the lingering impact of the energy crisis has left us with a market that's still highly volatile and quick to react to any bad news on the supply front.
"Despite this, while we don't expect a return to the extreme prices of recent years, it's unlikely that bills will return to what was once considered normal.
"Without significant intervention, this may well be the new normal."
