Support for improving your home

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

How ECO works

Under ECO, larger energy suppliers fund the installation of energy efficiency measures in British households.

Each obligated supplier has an overall target based on its share of the market. This consists of a number of obligations some of which direct support at particular groups of people.

Help doesn’t come in the form of payment. Instead, energy suppliers work with installers to introduce certain efficiency measures into your home, such as loft or wall insulation or replacement boilers.

The ECO obligations explained

The Home Heating Cost Reduction Obligation (HHCRO), also known as the Affordable Warmth Obligation, requires suppliers to promote the installation of heating qualifying actions, including insulation and the repair and replacement of boilers and electric storage heaters, to people receiving certain benefits and who live in private domestic premises.

The Carbon Saving Community Obligation (CSCO) requires suppliers to promote the installation of insulation measures and connections to district heating systems for:

  • areas of low income
  • people receiving certain benefits and living in private domestic premises
  • vulnerable households in rural areas.

You can use our online CSCO tool to find out if you live in an eligible area.

Finally, under the Carbon Emissions Reduction Obligation (CERO), obligated suppliers must promote ‘primary measures’, including roof and wall insulation and connections to district heating systems. Other ‘secondary measures’, which improve the insulating properties of a premises can also be installed at the same premises as primary measures.

You can benefit from CERO and CSCO is you live in your own home or live in social housing. You can only benefit from HHCRO if you own your own home or are a tenant in the private rented sector and have the homeowner's permission.

Can I benefit from ECO?

It’s important to note that ECO support is available through any of the obligated suppliers, and not just the one you get energy from.

You can contact any of the obligated suppliers to find out how they may be able to help you.

You can also get free and impartial energy efficiency information though a number of consumer advice services such as The Energy Saving Advice Service in England (0300 123 1234) or Home Energy Scotland (0808 808 2282).
