What is the ECO4 Scheme?

According to GOV.UK, the Energy Company Obligation (ECO4) is a government scheme that requires larger energy suppliers to help households improve their energy efficiency.

The scheme runs from April 2022 to March 2026 and provides free energy efficiency measures to eligible households across Great Britain (England, Scotland, and Wales).

What Happens After ECO4 Closes?

The Warm Homes Plan Takes Over

According to GOV.UK, the Warm Homes Plan is designed to succeed and expand upon ECO4. It aims to provide up to £30,000 per household for comprehensive energy upgrades including insulation, heat pumps, solar panels, and battery storage.

The Great British Insulation Scheme (GBIS) also continues alongside, providing insulation specifically based on Council Tax band eligibility — a broader route than ECO4's income-based criteria.

Don't qualify for ECO4? You may still get £7,500

The Boiler Upgrade Scheme has no income restrictions and runs until 2028. If you're a homeowner in England or Wales looking to replace your gas or oil boiler with a heat pump, you could receive a £7,500 government grant — regardless of your income.

  • No income requirements — available to all homeowners
  • Runs until 2028 — no rush, but funding is first-come first-served
  • £7,500 deducted directly from your installation cost
