Typical Energy Bill to Rise by £221 from July Amid Iran War Fears

Ofgem’s energy price cap continues to affect millions of households in England, Wales and Scotland, while energy regulation and bills work differently in Northern Ireland. The cap sets the maximum amount suppliers can charge for each unit of gas and electricity on variable tariffs, meaning it limits the rate paid rather than the total bill. Around 40% of bill payers are on fixed tariffs and are not affected by the cap until their current contract ends, because their prices remain locked in for the duration of the fixed term.

The cap is presented by Ofgem using a “typical household” example, based on annual energy use of 11,500 kWh of gas and 2,700 kWh of electricity, with gas and electricity combined into a single bill paid by direct debit. This benchmark is designed to show what an average household might pay, although actual bills vary depending on usage, tariff type and payment method.

Ofgem has now decided to lower what it considers a “typical” level of household energy use. The regulator says many homes have reduced consumption because of the sustained rise in energy prices over recent years, while energy efficiency improvements have also lowered demand. The change in the benchmark is intended to reflect these shifts in household behaviour and energy use patterns.

However, the adjustment could make the headline figures appear less severe than the underlying increase in energy costs. Even if the typical usage assumptions are revised downward, households will still pay significantly more for each unit of gas and electricity. In other words, a smaller “typical bill” does not mean prices are falling. It mainly reflects lower assumed consumption, not cheaper energy.

From July, Ofgem’s current estimate for a typical annual bill is £1,862, which would be £221 higher over the year. Under the proposed new usage assumptions, the typical bill would fall to £1,663. But that would not represent a real reduction in the cap’s impact, because the current cap calculated using the new assumptions would be around £1,490, implying a similar overall rise. The key change is the level of energy usage used in the calculation, not the direction of the price movement itself.

Ofgem has updated its typical domestic consumption values before, including in 2019 and 2023. These revisions show that the regulator periodically adjusts its assumptions to match how people actually use energy. The latest change is part of that same process, but it comes at a time when energy affordability remains a major concern for households facing persistent cost pressures.

Overall, the cap still plays a central role in limiting the cost of variable energy tariffs across most of Great Britain. Yet the headline figure for a “typical household” may soon look lower simply because Ofgem is assuming reduced usage, not because the market is becoming cheaper. Households will still need to pay close attention to actual unit rates, standing charges and the type of tariff they are on, since those factors determine the real impact on bills.
