Household Energy Debt and Arrears Statistics

Household energy debt in Great Britain reached £3.7 billion by June 2024, against £1.8 billion at the end of 2021, according to Ofgem statistics cited by the National Audit Office¹. The same £3.7 billion figure appears in a Scottish Government report published in April 2025². Households in arrears owed an average of £1,600 to their energy supplier as of November 2025³.

The totals matter because they describe two different things. Supplier-reported debt is what is owed on live accounts and being pursued. Wider estimates include arrears that have been passed to collection, written off, or accumulated across a period the regulator defines as the energy crisis. Ofgem's own consultation on a debt relief scheme put the debt and arrears accumulated during that proposed crisis period at £1.29 billion⁴.

Household energy debt has more than doubled in three years

The growth rate is the headline. Ofgem's December 2024 consultation on debt standards recorded a 91% increase, or £1.82 billion, in domestic energy debt and arrears over two years⁵. Speaking in September 2023, Ben Lake MP, chair of the All-Party Parliamentary Group on Fuel Poverty and Energy Efficiency, described energy debt as soaring by 70% over the previous three years⁸. The two figures cover different windows and different measures, so the precise rate depends on the period chosen, but both point the same way.

The composition of the debt has shifted as well as its size. Ofgem's consumer vulnerability progress report shows the average balance at the point a repayment plan is agreed rising from around £698 for electricity and £592 for gas in 2020 to £1,049 and £862 respectively in 2025⁶. That is the debt households carry into a plan, not the debt they clear. A household entering a repayment arrangement in 2025 started roughly £350 further behind on electricity than one entering in 2020.

The £3.7 billion total is not the only figure in circulation. Independent reporting in 2026 has put household energy debt at around £5 billion, and separately at £4.79 billion, and those two figures are unresolved against each other and against the Ofgem-derived total¹. The difference is largely one of scope: whether the number counts only live domestic accounts, or adds debt that has been sold, parked or written off. For a household trying to understand its own position, the average arrears figure of £1,600 is the more useful reference point, because it describes what a supplier is actually pursuing³.

What drives the total is not one thing. Arrears accumulate where a bill rises faster than a household can adjust, where a payment method makes budgeting harder, and where a household absorbs a shock such as a job loss or illness without a buffer. The debt stock is therefore slow to fall even when prices stabilise, because the households inside it have already exhausted the easy adjustments.

How much households owe: the headline figures

The published figures describe debt at several different points in its life, and reading them together gives a clearer picture than any single number.

Ofgem's debt relief consultation adds a distributional detail that the headline totals hide. Initial estimates placed a debt range of £500 to £1,500 and arrears of £1,500 to £3,000 as the most common levels for households in the bottom three income deciles⁴. In other words, the households least able to absorb a shock are carrying the largest balances, and the arrears component is often two to three times the size of the original debt.

The gap between the £1,600 average arrears figure and the £1,049 and £862 average balances at repayment plan is not a contradiction. The first describes households in arrears generally, including those not yet on a plan. The second describes the subset that has reached an arrangement, and it is measured at the moment the plan begins. Households that never reach a plan, or that leave one, are not captured in the second figure at all.

Why arrears build up: bills, the price cap and standing charges

The price cap is widely misunderstood as a ceiling on bills. It is not. It limits the unit rates and standing charges a supplier can apply to a default tariff, so a household that uses more pays more. The National Audit Office records that the cap limited the average annual household bill to £1,717 for October to December 2024, which was higher than pre-energy crisis levels and a 10% rise, an additional £149¹. The cap rose by 54% on 1 April 2022, taking the average annual domestic energy bill to around £2,000⁹.

Standing charges are the part of the bill a household pays before using any energy at all, and they have moved independently of unit rates. Ofgem's February 2025 announcement noted that some households would see a small increase in standing charges of up to £20 per year for a typical dual fuel consumer from 1 April¹⁰. The August 2025 announcement attributed part of the cap change to increases in the costs of transporting energy in Great Britain, that is England, Scotland and Wales, and to costs towards government schemes and essential support¹¹. Electricity balancing costs added around £1.23 a month to the average household bill¹¹.

For the cap period running 1 July to 30 September 2026, Ofgem's published tables show the Northern region electricity benchmark at a £223.48 standing charge and an £824.03 annual bill at 2,500 kWh single-rate, or a £220.70 standing charge and £986.44 annual bill at 3,400 kWh multi-rate¹². Those are benchmark figures for a defined consumption level, not a cap on what any household pays.

The practical consequence is that a household can do everything the advice suggests, cut usage, switch to a cheaper payment method, and still see the bill rise, because standing charges and the scheme costs inside the cap are outside its control. That is the mechanism by which arrears build even among households that are managing their consumption carefully.

Fuel poverty and who is most exposed

Fuel poverty and energy debt overlap but are not the same measurement. In general, fuel poverty relates to households that must spend a high proportion of their household income to keep their home at a reasonable temperature¹³. England applies a narrower test than the rest of the UK: only households in homes with energy efficiency bands D to G that fall below the poverty line after energy costs are counted as fuel poor¹³.

The latest estimates put around 11% of households in England as fuel poor¹³. The 2025 figures give 2.36 million households, or 9.4% of all households⁷. The two percentages differ because they come from different releases and reference periods.

Exposure is uneven by heating fuel. Among fuel poor households in England in 2025, 16.2% used oil and 16.9% used electricity¹⁴. The fuel poverty gap, the amount by which a household's income falls short of what it needs to heat its home adequately, was above average for those using electricity for heat, at £730¹⁴.

The trend has been volatile. The fuel poverty rate in England rose to a peak of 11.9% in 2009¹⁵, and the statistics covering that period were published by government on 14 July 2011¹⁶. More recently, the Department for Energy Security and Net Zero estimated that even after government support, the increase in energy prices meant around 238,000 more households fell into fuel poverty¹. The Department for Energy Security and Net Zero is the data source behind the England fuel poverty indicator¹⁷.

What suppliers and Ofgem can do when you fall behind

Suppliers have obligations and discretionary tools. Ofgem's consumer guidance sets out what a household can ask a supplier to do when struggling to pay for energy or when difficulty is anticipated: agree a payment plan, agree a payment break or reduction, review payments and debt repayments, and give access to hardship funds¹⁸. Those are things a supplier can do, not things it must do in every case.

The regulator's enforcement route runs through licence conditions. Ofgem's debt relief scheme delivery guidance, published in November 2025, states that where a supplier fails to meet the requirements, Ofgem may take enforcement action and record non-compliance on its Supplier Performance Report¹⁹. That gives the scheme teeth that voluntary arrangements lack.

The Energy Company Obligation is a separate lever, aimed at efficiency rather than debt. Ofgem calculates suppliers' obligations and tracks performance against them, processes notifications, audits suppliers, runs counter fraud work and reports to the Secretary of State at the Department for Energy Security and Net Zero²⁰. Obligated suppliers notify Ofgem of the measures they have delivered²¹. A household can contact any of the obligated energy suppliers to find out how they may be able to help, even if that supplier is not the household's own energy provider²². Eligible residents need to contact a participating energy supplier, and the list is published by Ofgem²³.

There is also a referral route through the Great British Insulation Scheme. Suppliers can use their own energy debt data to identify and refer eligible households through local authority and supplier flex, or work with relevant authorities under the scheme²⁴. That matters because it links the debt record a supplier already holds to an efficiency measure that reduces the bill generating the debt.

For complaints that cannot be resolved, Citizens Advice's free consumer service can help people in England or Wales with problems with their energy bills or supply²⁵. The service may refer a household to the Extra Help Unit where support is needed with a difficult or urgent complaint, where the household cannot deal with the supplier alone because of personal circumstances, where the household is considered vulnerable, or where there is a risk of disconnection²⁶. The Extra Help Unit supports vulnerable consumers by raising complaints with energy suppliers on their behalf, particularly where there is a risk of disconnection or complex personal circumstances²⁷.

Where to get free help: Citizens Advice and National Energy Action

Free, independent advice exists in every part of the UK, though the organisations differ.

Citizens Advice offers information and support on struggling to pay bills, problems with an energy supplier or supply, saving energy at home and getting a better energy deal²⁸. Its consumer service is free and its opening hours are Monday to Friday, 9am to 5pm²⁹. National Energy Action provides free advice about energy bills and keeping warm and safe in the home, and can also help with benefits advice and income maximisation³¹. A British Sign Language interpreter can be requested³¹.

In Northern Ireland the picture is different, because the supplier and regulatory landscape is different. The Consumer Council NI and Northern Ireland Energy Advice give free, independent and impartial energy advice to all domestic householders in Northern Ireland³³. Northern Ireland Energy Advice covers saving energy in the home, energy efficiency grants and oil buying clubs³². Energy suppliers in Northern Ireland refer customers who are struggling to pay bills to organisations such as Advice NI, which offers free, independent debt advice³⁴.

Is there a debt relief scheme for energy arrears?

Ofgem consulted in December 2024 on a debt relief scheme, and the consultation document sets out the shape it might take. It estimated that a scheme could write off £0.5 to £1 billion, against £1.29 billion of debt and arrears accumulated during the proposed definition of the energy crisis period⁴. The average consumer contribution toward the socialised cost of debt was put at around £70 per year, with the amount varying by payment method⁴.

Delivery guidance followed in November 2025, which indicates the scheme is being taken forward rather than merely considered¹⁹. The guidance sets out the enforcement consequence for suppliers that fail to meet the requirements¹⁹. What the documents do not provide is a confirmed opening date, a confirmed eligibility test for households, or a confirmed final write-off figure. Those remain to be settled.

The design question the consultation confronts is who pays. Writing off debt removes it from the household's account but does not remove the cost, which is spread across other billpayers through the socialised levy. At around £70 per household per year, the cost is modest in absolute terms but falls on the same population that is already carrying arrears⁴.

For a household currently in arrears, the practical position is that no scheme is open to apply to on the evidence published so far. The routes available now are the supplier's own payment plan, payment break or reduction, hardship funds, and the referral routes through Citizens Advice and the Extra Help Unit¹⁸.

What this means for energy independence at home

Energy debt is the clearest measure of the opposite of independence. A household in arrears is dependent on a supplier's forbearance, on a repayment schedule it did not set, and on the continuation of a supply it cannot afford to lose. The £3.7 billion of domestic energy debt at GB level is the aggregate of that dependence².

The dependence runs in several directions at once. A household on a default tariff is exposed to the price cap, which moves with wholesale costs, network charges and scheme costs rather than with anything the household controls¹¹. A household using electricity for heat carries a fuel poverty gap of £730, above average, because the fuel it depends on is the more expensive one¹⁴. A household using oil is exposed to a different market entirely, and 16.2% of fuel poor households in England use oil¹⁴.

What reduces the dependence is not a single measure. Efficiency reduces the units needed, which reduces exposure to unit rates. Insulation reduces the standing demand that standing charges are levied against. On-site generation and storage reduce the volume bought from a supplier, though they do not remove the standing charge or the scheme costs inside the cap. The Great British Insulation Scheme referral route is one of the few mechanisms that connects a household's existing debt record to a measure that lowers the bill creating it²⁴.

The limits are worth stating plainly. None of these measures clears arrears. None removes the standing charge. None removes the household from the supplier relationship, and none removes the exposure to wholesale prices for whatever energy is still bought. For a household already in debt, the immediate levers are the supplier's payment arrangements and the free advice services; the structural levers, efficiency and on-site generation, act on the size of the bill rather than on the debt already accrued.
