Loft insulation grants

Quick answer

You may qualify for free or part-funded loft insulation through ECO4, the Great British Insulation Scheme or Warm Homes funding if your home has a low EPC rating and your household meets common low-income or vulnerability criteria.

Why loft insulation matters

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.

Who may qualify?

Frequently asked questions

How thick should loft insulation be?

Current standards aim for around 270mm of mineral wool or equivalent.

Can I store things in my loft afterwards?

Yes, but you may need a raised loft floor to avoid compressing the insulation.

Will it cause condensation?

Properly installed insulation includes ventilation considerations to prevent condensation.

Do I need to be on benefits to apply?

Not always. Many schemes also accept lower-income households or households with vulnerable occupants under local authority flexible eligibility (LA Flex).

Does this checker guarantee funding?

No. It is a guidance tool. Final eligibility is confirmed by the relevant scheme provider, council or approved installer.
