Energy debt in British households has hit £3.7bn, double the figure from two years ago. That is not an abstract number on a regulator’s spreadsheet. It is the arrears sitting on the bills of 6.3 million homes, many of which are now cutting back on food or heating to keep the lights on.
A cross-party group of MPs has now proposed a radical fix: force Ofgem to redirect £4bn of excess profits from electricity and gas network companies into a targeted debt relief scheme. As reported by the UK Parliament, the proposal would target the £4bn windfall that network companies have accumulated through higher-than-expected returns on their regulated assets, money that was meant to be spent on infrastructure but instead boosted shareholder dividends.
Who qualifies, and who doesn’t
The MPs’ plan is not a universal handout. It would focus on households in fuel poverty, roughly 13% of UK homes, according to the latest official data. Eligibility would be based on income, energy tariff type, and whether the household has already exhausted existing support schemes such as the Warm Home Discount or the Energy Company Obligation (ECO).
For a typical low-income household with arrears of £1,200, the scheme could write off the full amount. That matters because energy debt is now the single biggest driver of county court judgments in England and Wales. Ofgem data shows that 1.2 million households are repaying debt through prepayment meters, often at higher rates than direct debit customers, and the average repayment period has stretched to five years.
The catch is that the £4bn figure is not guaranteed. Network companies are already challenging the regulator’s calculations, arguing that their returns are within the allowances set by Ofgem in 2021. The MPs acknowledge this: their report calls on Ofgem to “revisit the methodology” and, if necessary, use its statutory powers to claw back excess profits.
What it means for your EPC and retrofit plans
Debt relief sounds like a consumer protection measure, not a retrofit policy. But the two are linked. Households that are behind on bills cannot afford the upfront cost of insulation, double glazing, or a heat pump. The Energy Saving Trust estimates that a typical 3-bed semi could save £300 a year on heating bills with cavity wall insulation and loft top-up, but the installation cost of £1,500 is out of reach for families already paying off £2,000 in energy arrears.
If the debt relief scheme clears those arrears, it frees up household cash flow. The MPs propose that the scheme should be administered through local authorities or energy suppliers, with a “conditionality” clause: households that receive debt write-off must agree to an energy efficiency assessment and, where feasible, install cost-effective measures under ECO or the Great British Insulation Scheme. That would directly improve EPC ratings, typically from band E or F to D or C, and reduce future bills.
Ofgem has not yet responded to the report. But the timing matters: the next price cap review is due in February 2025, and the regulator has already signalled it will consult on network company profits in the spring. Homeowners should watch this space, if the scheme goes ahead, it could be the single biggest intervention in domestic energy debt since the winter fuel payment expansion.
What this misses, and what comes next
The MPs’ proposal is ambitious, but it has a blind spot. The £4bn windfall is a one-off. Energy debt, by contrast, is structural. The UK’s leaky housing stock, the oldest and most inefficient in western Europe, means that even with debt relief, households will rack up new arrears if they cannot afford to heat their homes.
The government’s own Net Zero Strategy estimates that 19 million homes need to reach EPC band C by 2035. At current installation rates, that target will be missed by a decade. Debt relief without retrofit is a sticking plaster. The MPs know this, their report explicitly calls for the scheme to be “part of a broader strategy” that includes mandatory minimum energy efficiency standards for private rented homes and expanded funding for the Social Housing Decarbonisation Fund.
For homeowners reading this, the immediate action is clear: if you are behind on bills, contact your supplier about the Warm Home Discount or ask for a payment plan under the Energy Company Obligation. Do not wait for a parliamentary scheme that may take months to design. And if you are not in debt, check your EPC rating, a home at band D or below is costing you roughly £400 a year more than a band C equivalent. The cheapest insulation is the kind you install before the next price cap rise.
Frequently Asked Questions
No, the scheme is not automatic. It targets households in fuel poverty, around 13% of UK homes, based on income, tariff type, and whether you've already used support like the Warm Home Discount. If eligible, a typical low-income household with £1,200 arrears could have the full amount written off, but you'd need to agree to an energy efficiency assessment first.
Energy debt makes it hard to afford upfront costs for insulation or heat pumps. For example, cavity wall and loft insulation costs £1,500 but can save £300 a year on bills. If the debt relief scheme clears your arrears, it frees up cash flow, and you may be required to install cost-effective measures under ECO or the Great British Insulation Scheme, improving your EPC from band E or F to D or C.
Eligibility focuses on households in fuel poverty, which is roughly 13% of UK homes. You'd need to be on a low income, have a specific energy tariff, and have exhausted existing support like the Warm Home Discount or Energy Company Obligation (ECO). The scheme would target those with arrears, such as £1,200, and could write off the full amount.
