Energy arrears emerge as key warning of debt crisis

Energy bill arrears are emerging as an early warning sign of wider financial distress. Households that fall behind on energy costs are far more likely to struggle with other essential payments, according to new analysis from financial support portal Lightning Reach.

The fintech analysed data from 280,000 people who used its platform to access financial assistance. It found that energy debt often coincided with pressure on both priority bills, such as housing and council tax, and non-priority borrowing, such as personal loans.

Households struggling with energy costs were more likely to face problems elsewhere than those not behind on energy bills. Those in energy debt were more than four times as likely to struggle with water bills and 2.5 times as likely to have difficulties paying council tax.

The analysis also found a strong link with housing costs. People behind on energy payments were more than 50% more likely to fall behind on housing payments, and twice as likely to have difficulty keeping up with loan repayments.

The figures add to evidence that energy debt has become a marker of broader financial hardship. Utility bills sit alongside rent or mortgage payments, council tax, and other commitments that households prioritise. Missing energy payments can signal that income is no longer stretching across multiple categories.

Vulnerable groups

The data suggests a disproportionate impact on households with children and disabled people. Lightning Reach found that 57% of those struggling with energy debt had dependent children.

People reporting a disability were also more likely to face energy difficulties. The analysis put the figure at 64% for those reporting a disability, compared with 56% for those who did not.

These groups often face higher and less flexible household costs. Families with children have additional spending on food, clothing, and transport. Many disabled people face extra costs linked to care needs, specialist equipment, or higher energy use at home. Those pressures can leave budgets more exposed when energy prices rise or income falls.

Energy debt levels have also been rising in the wider market. Ofgem data shows energy debt and arrears in England, Wales and Scotland increased by more than £750 million in the third quarter of 2025 compared with 2024. Customers owed energy suppliers £4.4 billion, according to the regulator.

Support access

Lightning Reach runs a platform that directs users to financial support matched to their circumstances. It says it has helped almost 300,000 people since launch and has facilitated more than £25 million in support.

The platform works with councils, housing associations, charities and utility-related trusts. Its network includes The Royal British Legion, Teaching Staff Trust and Lambeth Council, alongside energy providers OVO and E.on Next.

Ren Yi Hooi, CEO and founder of Lightning Reach, said the pattern suggests households can move quickly from one missed bill to a broader financial crisis.

"This signals that, for many, energy debt is just the tip of the iceberg, and the cost-of-living crisis runs far deeper," Hooi said.

Lightning Reach also said awareness of available support remains uneven, even where schemes exist through local authorities, charities and industry-linked trusts. It warned that households may delay seeking help until arrears have built up across multiple bills.

"As bills continue to rise, those already struggling risk running out of financial room altogether. Without better awareness of, and access to, the support that already exists, more households risk tipping from coping into crisis," Hooi said.

Policy backdrop

The analysis comes as the government develops measures aimed at reducing household energy costs over the longer term. Hooi pointed to the Government's Warm Homes Plan, which includes funding for green technology and energy-efficiency measures.

"The Government's Warm Homes Plan, which will offer funding for green tech to cut energy bills, is one of the most significant signals yet that the government is serious about tackling energy bills at the source. However, successful delivery will depend on whether this support can be rolled out without friction," Hooi said.

Lightning Reach expects energy debt to remain a key indicator for identifying households at risk of wider arrears-particularly families with children and disabled people-as regulators, councils, charities and suppliers refine how they target financial support.
