Three million households owe their energy supplier an average of £1,800. The price cap rose 4 percent this week to £1,723, a three-year high, and January is forecast to add another 9 percent. The industry has now priced the fix: a £1.9 billion social discount for 7.2 million households, paid for, it suggests, out of general taxation rather than bills.
This is not about whether people need help. The numbers say they do. It is about who pays for the help - and the answer is not the one in the headlines.
The Crisis, Fairly Stated
Household energy debt hit a record £6 billion at the end of June, and the industry body Energy UK projects £7 billion by the end of the year. More than three million customers are in debt or arrears, owing an average of about £1,800, and three-quarters of that total is arrears - unpaid bills with no repayment plan - the money least likely ever to be recovered. The debt charity StepChange sees an average of around £2,600 among the households that come to it for help.
Bills are roughly 70 percent above their pre-2022 level. The electricity VAT cut is buried inside this week’s cap print: the government removed VAT from electricity bills from October to March, lowering the cap by about £45. The visible tax was cut; the cap still rose. January is forecast worse - Cornwall Insight projects £1,872, about 9 percent above October, and some supplier forecasts run higher still.
These are not soft numbers. The industry has an interest in being paid, and its own figures document the failure.
So far the state’s answer has been to collect the cost of the failure from the people who do pay.
The Line on Your Bill You Did Not Choose
The price cap is described as a ceiling on what suppliers can charge. It is also a collection mechanism.
Every cap period includes a bad-debt allowance: a sum, approved by the regulator, that lets suppliers price unpaid bills into everyone else’s bills. Energy UK puts the allowance at roughly £50 a year on a typical dual-fuel direct-debit bill, and about £140 for standard-credit customers, who carry a disproportionate share of the debt.
When a household cannot pay, the debt does not vanish. It is folded into the allowance, recalculated every cap period, and spread across the bills that are paid. At the projected £7 billion total, the allowance grows again - another £10 to £15 on the typical bill.
The state lets suppliers collect the cost of unpaid bills from the people who do pay. That is socialization of loss - not through the Budget, where it would be visible and debated, but through the bill, where it appears as one line among many.
The mechanism is guaranteed whatever happens to the households underneath it. That is what an allowance in a regulated price does: the supplier gets paid for the debt, one way or another, out of the bills of the people who can pay. The risk is socialized. It’s not carried by the private company. The cost is priced into other people’s bills.
The Rebate That Pays for Itself
The Warm Home Discount is the state’s main instrument: £150, flat, once a year, to around six million recipients on means-tested benefits.
The £150 comes from the unit rate. Every billpayer pays it, including the recipients. The industry’s own report states the consequence in plain words: “the costs of the WHD scheme are met by all billpayers, including recipients, so for them the net benefit works out much less than £150.”
The industry’s word for this funding mode is regressive. Recipients pay toward their own rebate. The poor pay for the poor’s discount, collected through the bills of the poor.
And the rebate inflates away. £150 is only £10 more than a decade ago, while bills have doubled. As a share of a typical bill, the discount has fallen from around 15 percent in 2017 to under 9 percent now. The support shrinks in real terms while the crisis grows, and it shrinks because of the funding mode.
The Fix, Costed by the Industry
Last week Energy UK published the industry’s own proposal: a social discount replacing the Warm Home Discount, with tiered rebates averaging £265 and reaching £450 for the households under the most pressure - 7.2 million households at about £1.9 billion a year, roughly double the current scheme. Scaled to 2022-23 prices, the same design would cost about £14 billion: 40 percent of what the government spent on support in that crisis year.
The report also recommends moving the discount off bills and onto general taxation - in its words, funding through government spending would be “most beneficial to energy customers and progressive.”
Give them credit. That is the right direction. General taxation is a broader base than the unit rate, and the cost spreads across shoulders that can bear it. If the choice is between the bill-funded Warm Home Discount and a Treasury-funded social discount, the Treasury door is the fairer one.
Now follow the incidence. A Treasury-funded discount is paid by the taxpayer. The Budget on October 28 is where the decision lands. When a minister says “the government will pay,” the government is a tax collector, and the money comes from the same population - through income tax, through VAT, through whatever the Budget chooses. The check-writer changes. The payers are the same people, through a different door. Taxes - Who Actually Pays walks through exactly this: the person who writes the check is not always the person who bears the cost, and the person the state claims to be helping may be the person paying for the help.
Fund the discount from the Budget and the state gets the credit for support without a visible tax line. No line on any bill says “social discount levy.” The tax that funds the headline is anonymous, decided at a Budget nobody reads. The VAT cut is the same arithmetic: the government cut the visible tax while the cap still rose 4 percent.
Who Profits?
Follow the money, as always.
Suppliers get a guaranteed recovery line. The bad-debt allowance is recalculated every cap period, so the debt grows into a bigger allowance, collected from the bills of the paying customers. And suppliers would administer the social discount - they already run the Warm Home Discount.
The state gets the credit for the help without a visible cost. Cut the VAT, promise the discount, let the Budget find the money. The announcement is the product; the funding is a future footnote.
The charities get a fundraising story. A record debt total is a campaign engine, and £2,600 is the figure that opens the appeal.
And an ex-PM gets a headline. Gordon Brown, on the cap print, proposed a “machine gaming tax” to fund bill support and a social tariff - then pre-committed the current PM: “I think Andy Burnham, I know him well, will want to do something along the lines I’m suggesting.” An ex-PM announcing what the PM will do, before the PM has said it. The manufactured mandate, running one step ahead of the poll.
Nobody in that chain pays the bill. That is the point of the chain.
The Same Pot, Two Doors
The British Industrial Competitiveness Scheme exempts energy-intensive manufacturers from the indirect costs of the Renewables Obligation, the Feed-in Tariff, and the Capacity Market - up to 100 percent. The exemptions start April 2027, and the funding was settled in advance: the Exchequer pays, so that “domestic and non-domestic electricity consumers do not see an increase in their electricity bills as a result of the scheme.” The delivery consultation closes September 9.
Two doors, one pot. When industry cannot pay its share of the system’s costs, the state reaches for general taxation and promises no bill increases. When households cannot pay their bills, the default has been the bill itself - the Warm Home Discount collected from the billpayers who need it most - and the move to general taxation awaits a decision at the Budget.
The same pot pays both. The difference is which door the money comes out of, and who decided that. The state protects the industrial bill from the Treasury and the Treasury from the household bill, then announces the discount that would move households through the door industry walked through first.
The Elasticity Echo
The state’s model of the household is that price does not matter: people will pay whatever the bill says, so only a transfer can help them. Its model of the generator is the same: the windfall levy, raised to 55 percent in July, changes nothing about investment, so the revenue is free money. Both models deny that people and firms respond to the costs in front of them.
But the discount is itself a bet on responsiveness: money in the pocket changes what a household can afford. If households were truly unresponsive to price, the rebate would be pointless - the bill would be paid or not, regardless. The state believes in responsiveness when it hands out help, and denies it when it taxes. That is the selective model of human nature mapped in The Elasticity Denial: behavior is elastic when elasticity serves the policy, and rigid when rigidity serves the policy.
Same two models, aimed at the same households from both directions. Tax the generator, the response does not exist. Discount the household, the response is the entire premise.
What Happens When It Doesn’t Work
The support has been running for years, and the debt is at a record high. The Warm Home Discount was expanded to six million customers, and the arrears kept climbing. More than a million households have no registered details with their supplier - the support cannot reach them at all.
When the fix does not fix, the cost does not disappear. It is repriced into the allowance, onto the next cap, onto the bills of the people who do pay. The failure is not absorbed. It is redistributed.
That is the layer the announcements skip. A bigger discount, funded by the Budget, still leaves the underlying question: the mechanism that collects the failure is the mechanism that funds the help. Move the funding to the Treasury and the collection point changes, but the payer - the same population, through a different door - does not.
The Question
When the state hands out bill support, ask who pays for the handout. The billpayer whose bill already carries the debt allowance, or the taxpayer at the Budget - and who decided the difference.
The people announcing the help will not be the people paying for it. That is true in both designs. The bill-funded version collects from the poor in the name of the poor. The Treasury-funded version collects from everyone, invisibly, at a Budget nobody reads, and hands the credit to the politicians.
You get to choose which question you ask. Whether the help is real is one. Who pays for it, and who decided, is the one the announcements are built to skip.
