Energy Company Obligation (ECO)

The Energy Company Obligation (ECO) is a government energy efficiency scheme for homeowners and tenants in Great Britain to tackle fuel poverty and help reduce carbon emissions.

About ECO / ECO4

The ECO scheme is a government initiative that offers financial assistance for energy-efficient upgrades to households in Great Britain. Homeowners with a low EPC rating can apply for a package of energy-saving measures and heating improvements through the ECO scheme. It's worth noting that the scheme is not restricted to boiler upgrades or replacements.

The scheme has seen 4 iterations, ECO, ECO1, ECO2 and ECO3. The ECO3 scheme closed on 31 March 2022 and the ECO4 Order came into force in July 2022. ECO4 applies to measures installed from 1 April 2022 and will cover a four-year period until 31 March 2026.

How does ECO work?

The ECO scheme works by placing a Home Heating Cost Reduction Obligation (HHCRO) on medium and large energy suppliers. Under HHCRO, obligated suppliers must promote measures that improve the ability of low-income, fuel-poor and vulnerable households to heat their homes. This includes actions that result in reduced energy usage, such as installing insulation or upgrading a heating system. The overall target for these measures is divided between suppliers based on their relative share of the domestic gas and electricity market.

What measures are funded under ECO4?

You may be able to get support to install:

  • new energy efficient boiler
  • smart heating controls
  • first-time central heating
  • solar panels
  • air source heat pump

  • cavity wall insulation
  • under-floor insulation
