ECO4 and the Great British Insulation Scheme: eligibility explained

How the two main government-backed home insulation schemes work, who they are aimed at, and where to check eligibility. Information only.

Two government-backed schemes help fund home insulation and, in some cases, heating. The Energy Company Obligation (currently ECO4) is targeted at lower income and vulnerable households and less efficient homes.

The Great British Insulation Scheme is broader and focuses on single insulation measures such as cavity wall or loft insulation, with eligibility based partly on council tax band and the home's EPC rating.

Typical UK cost

Cost ranges are indicative and attributed to gov.uk: Energy Company Obligation (ECO). Prices vary by property, region and installer – always get quotes and check the official source.

Typical saving

Eligible households may have measures fully or partly funded, so the out-of-pocket cost can be much lower than paying privately.

Saving figures are indicative and attributed to gov.uk: Great British Insulation Scheme. Check the official source.

Payback

Eligibility and the exact measures depend on your circumstances and the home; check the official eligibility pages rather than relying on a general figure.

What affects the price

• Household income and whether anyone receives certain benefits (ECO4).
• Council tax band and the home's current EPC rating (Great British Insulation Scheme).
• The property's existing insulation and heating.
