Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what recent estimate he has made of the number of households in fuel poverty who live in properties that do not have loft insulation.

The latest annual fuel poverty statistics estimate that around 873,000 households in England were in fuel poverty in 2025 and lived in properties with under 125 mm of loft insulation, equivalent to a fuel poverty rate of 13.3% for this group. This compares with a rate of fuel poverty of around 7.8% (1.17 million households) among households with 125 mm or more of loft insulation, and 9% (316,000 households) among households where loft insulation is not applicable.

These estimates are produced under the Low Income Low Energy Efficiency (LILEE) metric and are published in Table 17 of the Fuel poverty detailed tables 2026 (2025 data).
