Start with the free guidance on GOV.UK and Citizens Advice, which explain current support schemes, benefits and help with energy debt. You can also ask your supplier about affordable repayment plans, hardship funds and joining its Priority Services Register if you need extra support. Check your eligibility for help such as the Warm Home Discount or council-run cost-of-living schemes, as availability and rules can vary. A free benefits calculator or local advice service may help identify support, but check final eligibility with the relevant government department or provider.
