There's no budgetary control of this, and yet it all ends up on household bills.
Across Britain, a quiet but consequential argument is unfolding between those who govern and those who supply — one that will determine how much ordinary households pay to keep the lights on. Parliament heard this week that energy bills are set to rise 20% over four years, not because the world's gas markets are misbehaving, but because the infrastructure and policy costs buried inside every bill have grown beyond any meaningful check. It is a story about the gap between long-term vision and immediate consequence, and about who bears the cost of a transition that has not yet arrived.
- Britain's largest energy supplier told MPs that household bills will rise 20% over four years even if wholesale gas prices collapse by half — a warning that strips away the usual political cover.
- The hidden drivers are network upgrade fees and green subsidies, which together account for more than half of the £500 increase households have absorbed since Russia invaded Ukraine in 2022.
- E.On's chief executive went further, telling the committee that even if wholesale prices fell to zero, bills would stay exactly where they are today — a stark illustration of how structural costs have outgrown market forces.
- The government pushed back, calling the suppliers' analysis speculative and pointing to fossil fuel volatility as the real culprit, while Energy Secretary Ed Miliband insists the clean energy transition will cut bills by £300 a year by 2030.
- Suppliers warn that the long-term vision does nothing for households struggling now, and are calling for radical policy reform before rising non-commodity costs make energy unaffordable for millions.
Britain's largest energy supplier walked into Parliament this week with a warning designed to cut through the usual political noise: household electricity bills are heading 20% higher over the next four years, and falling gas prices won't stop it. Octopus Energy's director for regulation and economics, Rachel Fletcher, told MPs that the real culprit is not the volatile global energy market — it is the growing pile of infrastructure and policy costs that get quietly bundled into every bill.
These non-commodity charges — fees for upgrading electricity and gas networks, keeping the system operational, and subsidising renewable energy — have become the hidden engine of rising costs. Network upgrade charges alone have climbed more than £140 annually over four years, now reaching £396 a year. Policy costs have risen £86 to £215. Of the roughly £500 increase households have absorbed since Russia invaded Ukraine in 2022, only about £200 traces back to wholesale energy prices. The typical household now pays £1,755 a year under the government's price cap.
Chris Norbury, chief executive of E.On UK, reinforced the point bluntly: even if wholesale prices fell to zero, bills would remain at today's levels because of non-commodity cost growth. Fletcher called for the kind of budgetary discipline applied to other taxes, warning that without it, these charges would keep compounding unchecked onto household bills.
The government rejected the suppliers' framing, calling it speculation and noting that wholesale gas costs remain 75% above pre-invasion levels. Energy Secretary Ed Miliband has staked his strategy on decarbonisation, arguing that moving Britain off gas-fired power could cut bills by up to £300 a year by 2030. But suppliers say that vision, however sound in principle, does nothing for the immediate crisis. Fletcher told MPs that radical options were needed now, before the trajectory became irreversible. The tension is clear: the government is playing a long game, while millions of households are already losing the short one.
Britain's largest energy supplier walked into Parliament this week with a warning that cuts through the usual political blame game: your electricity bill is going to keep climbing, and cheaper gas won't save you. Octopus Energy told MPs on Wednesday that household bills are tracking toward a 20% increase over the next four years—even in a scenario where wholesale electricity prices fell by half. The culprit, according to Rachel Fletcher, the company's director for regulation and economics, is not the volatile global energy market. It's the growing weight of government policies and infrastructure costs that get bundled into every bill.
These non-commodity costs—the fees households pay to upgrade electricity and gas networks, keep the system running, and subsidize renewable energy projects—have become the hidden engine of rising bills. Fletcher, who has held senior positions at Britain's energy and water regulators, told the committee that "serious and urgent consideration" was needed to rein in this burden. She suggested the government might need to delay investments that weren't immediately necessary, and she called for the kind of budgetary control applied to other taxes. "There's no budgetary control of this," she said, "and yet it all ends up on household bills."
The numbers tell the story starkly. The typical household now pays £1,755 a year for dual-fuel energy this winter under the government's price cap. That's roughly £500 more than before Russia invaded Ukraine in 2022. But here's the disconnect: only about £200 of that £500 increase comes from wholesale energy costs. Network upgrade charges have climbed by more than £140 annually over the past four years alone, now sitting at £396 a year. Policy costs—the green subsidies—have risen by £86 to reach £215. The wholesale price, in other words, accounts for less than half the bill's growth.
Chris Norbury, chief executive of E.On UK, reinforced the point with his own company's modeling: even if wholesale prices hit zero, bills would remain where they are today because of non-commodity cost increases. The government, predictably, rejected the suppliers' framing. A spokesperson said the analysis was "speculation" and pointed out that wholesale gas costs remain 75% higher than before the 2022 invasion. Energy Secretary Ed Miliband has staked his strategy on a clean energy transition, arguing that moving Britain away from gas-fired power plants could reduce bills by up to £300 a year by 2030.
But the suppliers are saying that vision, however sound in principle, doesn't address the immediate crisis. Fletcher and Norbury told MPs that simply removing gas plants from the grid wouldn't be a fix unless the fundamental cost drivers were tackled now. "We need a government that is looking at a range of radical options," Fletcher said, "to much more quickly address the path that we're on before it's too late." The tension is real: the government sees the long game—decarbonization as the path to cheaper, stable energy. The suppliers see the near term—bills climbing faster than policy can bend them down, with no mechanism to control the growth. For millions of households already struggling with energy costs, the question is which timeline matters more.

So the suppliers are saying wholesale prices don't matter much anymore. Is that actually true?
It's more precise to say they matter less than people think. Wholesale costs did spike after 2022, and yes, that's real. But the underlying structure of the bill has shifted. The fixed costs—networks, system operation, green levies—those are growing faster than the variable cost of fuel itself.
Why would the government not just cap those costs the way they cap wholesale prices?
That's exactly what Fletcher is asking. There's no budgetary control mechanism. Each policy gets added to the bill individually, and nobody's looking at the total weight. It's like a tax that nobody votes on.
But the government says clean energy is the answer. Doesn't that eventually solve this?
Theoretically, yes. Renewable power is cheaper to run once built. But that's a five-to-ten-year story. People's bills are rising now. The suppliers are saying the government needs to act on costs today, not just promise lower bills in 2030.
What would "radical action" actually look like?
Delaying some network upgrades that aren't urgent. Restructuring how green subsidies are funded—maybe through general taxation instead of bills. Basically, taking some of this burden off households and putting it elsewhere.
And if nothing changes?
Bills keep climbing. Network costs alone have gone up £140 a year in four years. At that rate, you're looking at unaffordable energy for a lot of people, regardless of what happens to gas prices.
