Millions of households across Britain are struggling to keep up with their energy bills, with unpaid household energy debt and arrears now estimated at £6 billion, according to industry group EnergyUK. The warning comes as households face the prospect of another increase in energy costs, with regulator Ofgem expected to announce a 4% rise in the domestic energy price cap this week, which would take the cap to its highest level in three years.
The £6 billion figure represents energy debt recorded at the end of June 2026, according to EnergyUK. The organisation presented the updated figure to journalists ahead of Ofgem’s expected price cap announcement, highlighting the growing financial pressure facing households that are already struggling to pay for essential energy.
The scale of the debt is significant because unpaid energy bills do not simply disappear. EnergyUK said unrecovered energy debt is spread across household energy bills, meaning consumers collectively contribute towards the cost. At present, this adds around £50 a year, or roughly 3% of a typical annual household energy bill.
EnergyUK has warned that without further intervention, the amount of unpaid energy debt could rise to £7 billion by the end of 2026. That would place additional pressure on households and suppliers at a time when many families are already dealing with higher living costs.
Energy bills could rise again
The warning comes as Ofgem prepares to announce its latest domestic energy price cap. The regulator is expected to increase the cap by around 4%, taking it to a three-year high.
For households already struggling with arrears, even a relatively modest increase can create another financial headache. Energy bills are unavoidable household expenses, and families cannot simply stop using electricity or heating when their budgets become tight.
The situation is particularly challenging for households that have already fallen behind on payments. A rise in the amount charged for energy can make it harder for customers to clear existing debts while also keeping up with new bills.
EnergyUK said the figures underline the need for action to address the growing number of households struggling with energy debt. The organisation has called attention to the scale of the problem as policymakers consider how best to support indebted consumers.
Why is energy debt increasing?
Energy debt has become a major concern in Britain as households continue to face pressure from energy prices and wider household costs. While wholesale energy prices are not the only factor affecting household bills, they remain a major influence on the domestic price cap.
The wholesale cost of energy has risen sharply this year, with the conflict involving Iran cited as a major factor behind the increase. Ofgem’s price cap is reviewed every three months and is calculated using a formula that takes account of wholesale energy costs as well as suppliers’ network costs and environmental and social obligations.
This means changes in wholesale energy markets can eventually feed through into household bills.
For a family already struggling to pay, the consequences can be significant. Missing one payment can lead to an outstanding balance, and if the problem continues, that debt can grow quickly.
£500 million debt support plan has stalled
Ofgem has been examining ways to support consumers who are struggling with energy debt. One proposal would involve clearing £500 million of debt for the poorest customers.
However, the scheme requires government legislation and has stalled, leaving uncertainty over when and how additional support could reach households experiencing the greatest financial difficulties.
The delay comes as EnergyUK warns that the overall level of unpaid energy debt could continue increasing. If the figure reaches £7 billion by the end of the year, it would represent a substantial increase from the £6 billion recorded at the end of June.
For struggling families, the issue is not simply about the size of the national debt figure. Behind the statistics are households deciding whether they can afford to heat their homes, keep up with payments and manage other essential expenses.
What the £6 billion energy debt means for households
The £6 billion figure provides a picture of the wider pressure facing Britain’s energy market, but its impact can also be felt through individual household bills. EnergyUK said the cost of unrecovered debt currently adds around £50 a year to a typical annual bill.
That means households that are managing to pay their bills are also indirectly affected by the wider level of unpaid debt across the energy system.
At the same time, customers who are already behind on their payments face a more difficult situation. They have to manage their existing arrears while dealing with the cost of future energy consumption.
The prospect of further increases in the price cap therefore comes at a sensitive moment for many families.
What happens next?
The immediate focus will be on Ofgem’s forthcoming announcement on the domestic energy price cap. The expected 4% increase would represent another rise in the cost pressure facing households and take the cap to a three-year high.
The wider question is how the UK can prevent energy debt from continuing to grow. EnergyUK’s warning that unpaid debt could reach £7 billion by the end of 2026 highlights the scale of the challenge facing policymakers, energy suppliers and consumers.
Ofgem’s work on support for indebted customers could become increasingly important, particularly if the proposed £500 million debt-clearing scheme remains delayed.
For households across Britain, the latest figures are another reminder that energy affordability remains a major issue. The cost of keeping a home warm and powered continues to affect household finances, while unpaid bills are creating a growing problem that ultimately has consequences for the wider energy market.
For Nigerian families and other diaspora households living in the UK, the situation can be particularly important to watch. Many households are balancing rent or mortgage payments, food costs, transport, childcare and other expenses, while some also support relatives financially in Nigeria and elsewhere. A relatively small increase in energy costs can therefore have a wider impact on the household budget.
The growing energy debt figure is not just a statistic. It reflects the financial pressure being experienced by households across Britain and raises fresh questions about how the country can make essential energy more affordable for people who are struggling to pay.
For Nigerians living in the UK, rising household costs can have an impact far beyond the monthly energy bill.
