Quick answer
You may qualify for free or part-funded loft insulation through ECO4 or Warm Homes funding if your home has a low EPC rating and your household meets common low-income or vulnerability criteria. The Great British Insulation Scheme closed to new applications on 31 March 2026.
Around a quarter of heat loss in an uninsulated home is through the roof. Topping up to 270mm of insulation is one of the most cost-effective upgrades.
