Loft insulation has been widely supported through schemes like ECO4 and GBIS for eligible households, and remains a strong candidate measure as the Warm Homes Plan develops. We'll help you understand what may currently apply to you.
Eligibility and availability depend on current scheme rules, property circumstances and household details. Emerald Green Energy does not guarantee funding.

Frequently asked questions

Common options include blanket roll, blown fibre, rigid board (often used for loft conversions), and natural-fibre options such as sheep's wool or wood fibre.
For most accessible lofts, installation is quick and minimally disruptive.
