Are External Wall Insulation Grants Available in 2026?
Yes — in 2026, external wall insulation grants are still available in the UK, although eligibility is more targeted.
These grants are designed to help households reduce energy bills, improve comfort and cut carbon emissions,
particularly in homes with solid walls.
Main Grant Schemes Covering External Wall Insulation
- Great British Insulation Scheme – Subsidised insulation for eligible homes
- ECO4 Scheme – Energy supplier funding for low-income or vulnerable households
- Local Authority Funding – Area-specific support via councils
External wall insulation is classed as a high-impact measure, meaning funding is prioritised for properties
with poor EPC ratings or high heat loss.
