How much will energy bills go up by?
As the conflict in Iran forces oil prices upwards, many households are bracing themselves for an increase in energy bills.
Published: 20 March 2026
And now we have some idea of just how much our bills might go up by.
Cornwall Insight estimates that in July, typical annual household energy bills could go up by £332 in July.
This would mean that a dual-fuel household using a normal amount of gas and electricity would pay £1,973 a year - up from £1,641.
Energy price cap won’t go up in April
If the forecasts are even broadly correct, that would represent a big increase in the cost of living for millions of households.
Last month, energy regulator Ofgem announced that in April, the energy price cap will fall by 7%.
That means the cap will drop by £117 to £1,641 a year for a typical dual fuel household - around £10 a month back in your pocket if you use gas and electricity.
And chancellor Rachel Reeves has insisted that the energy price cap will remain unchanged, despite the conflict in the Middle East.
This, she said, will give families “immediate certainty on their bills until at least the end of June”.
But Cornwall Insight’s predictions are a reminder that the situation remains extremely uncertain, and that there may be no way to prevent higher oil prices hitting consumers later this year.
Could the government offer energy bill support?
So far, the government hasn’t announced details of support for households apart from help for people who use heating oil.
But it hasn’t ruled out providing targeted support to consumers who are hit by rising energy prices either.
“Clearly, what happens at the end of that price cap period is still being worked through,” said energy minister Michael Shank.
“As we get closer to that period, we’ll have more evidence and be able to see what the price cap might do, and we stand ready to provide whatever support is needed to consumers.”
