The ECO4 Scheme (Energy Company Obligation Phase 4) is a UK government-backed program designed to improve energy efficiency in low-income and vulnerable households. It provides free home upgrades like insulation, boiler replacements, heat pumps, and first-time central heating systems.
You may qualify if:
You receive certain benefits (e.g. Universal Credit, Pension Credit, Income Support)
Your household income is under £31,000
Your home has a low EPC rating (D, E, F, or G)
Your current heating system is old or inefficient
The scheme may cover:
Free boiler replacement
Free loft and cavity wall insulation
Free air source heat pump installation
Free first-time central heating system
No. If you're eligible, the upgrades are 100% free, fully funded by energy suppliers under the government mandate.
Once your eligibility is confirmed, the whole process — from survey to installation — typically takes 1–3 weeks, depending on your location and property type.
