UK Household Energy Debt Hits Record £4.79 Billion as Prices Set to Rise
Regulator Ofgem reports that total debt and arrears owed to energy suppliers reached a record high in the first quarter of 2026, ahead of a significant price cap increase scheduled for July.
Total household energy debt in Great Britain has climbed to a record £4.79 billion, according to the latest figures released by the energy regulator, Ofgem. The data, which covers the first quarter of 2026, represents a 5% increase from the previous quarter and a 15% rise over the past year.
This new peak in arrears comes as households face further financial pressure, with Ofgem set to increase its energy price cap by 13% from 1 July 2026. For a typical dual-fuel household paying by direct debit, this will raise the annual bill to an estimated £1,862.
The number of households in debt to their energy supplier has also grown. Ofgem's data shows 852,000 electricity accounts and 710,000 gas accounts were repaying debt at the end of March 2026. The average debt for those with a repayment plan is £828 for electricity and £679 for gas. For customers in arrears without a repayment plan, the average amounts are significantly higher, at £1,876 for electricity and £1,623 for gas.
Support and Grants for Households
For those struggling with energy costs, several government and supplier-supported schemes are available. The Warm Home Discount scheme, for instance, is expected to provide a £150 rebate on electricity bills for eligible low-income households during the winter of 2026-2027. Eligibility typically depends on receiving certain benefits like Pension Credit or having a low income.
Longer-term support for improving home energy efficiency is available through schemes like ECO4 (Energy Company Obligation), which targets low-income households for upgrades such as insulation and more efficient heating systems. The Boiler Upgrade Scheme also offers grants of up to £7,500 towards the cost of installing eligible heat pumps in England and Wales. Additionally, a 0% VAT rate on energy-saving installations like solar panels and insulation is in place until March 2027.
Charities and advice organisations like Citizens Advice and National Energy Action urge anyone worried about their bills to contact their energy supplier directly. Suppliers are required to offer support, which can include setting up affordable repayment plans.
Practical Steps to Reduce Energy Consumption
Experts advise that simple changes in daily habits can lead to significant savings. Lowering the thermostat by just one degree can reduce heating bills by up to 10%. Similarly, washing clothes at 30°C instead of higher temperatures and only boiling the amount of water needed can save a household over £100 annually.
Other effective measures include improving home insulation and draught-proofing to prevent heat loss around windows and doors. Switching to energy-efficient LED light bulbs, unplugging devices from standby, and using appliances' 'eco' modes can also cut down on electricity usage. Keeping shower times short and ensuring heating systems are regularly serviced further contribute to efficiency.
