Energy Company Obligation

The Energy Company Obligation (ECO) is a government scheme requiring large energy suppliers to provide energy efficiency measures.

The current scheme targets low-income households living in hard-to-heat properties.

A range of measures are available through ECO, this includes:

  • insulation (external, internal, cavity, loft, flat roof, floor)
  • first-time central heating
  • heating controls
  • electric heating
  • micro-generation.

If you are a tenant or leaseholder, you will need permission from your landlord before having the work done. Landlords can also apply for ECO-funded measures but will need agreement from the tenant or leaseholder.

We are working with energy companies through ECO to carry out improvements, such as loft and cavity wall insulation, for households that meet certain eligibility criteria.

For further information about the scheme, including eligibility, please see support for improving your home on the Ofgem website.

If you do not meet the criteria, you may still be eligible under the Energy Company Obligation: Flexible Eligibility, or the upcoming ECO+ scheme for council tax bands A to D.

ECO: Flexible Eligibility

We have published a wider range of criteria, expanding ECO funding to more households and allowing non-eligible residents to get solid wall insulation through the in-fill scheme.

Only private renters and owner occupiers can apply under ECO Flexible Eligibility.

To check if you may be eligible, please see our latest ECO Flexible Eligibility Statement of Intent.
