ECO4 Scheme

The Energy Company Obligation (ECO4) is a government provided energy-efficiency scheme that is designed to tackle fuel poverty and also reduce carbon emissions.


ECO is not a grant scheme as it is your energy providers decision which retrofit projects that they choose to fund. ECO4 is aimed towards the least energy-efficient homes and households that are within fuel poverty.

Some of the measures that may be installed are:

  • insulation
  • boilers and central heating
  • solar and renewable energy technologies


To apply you must meet both of the following eligibility criteria:

  • you must be in receipt of means tested benefits
  • you must live in a property with an energy performance certificate rating of D, E, F or G

ECO Flex

ECO Flex is a household referral mechanism that falls within the ECO4 Scheme which allows us to use a wider eligibility criteria for ECO.


To apply you must meet any of the following criteria:

  • income – households with a gross household income of under £31,000
  • proxies – households that meet a combination of two proxies (examples of proxies include homes in areas of high multiple deprivation and households receiving a Council Tax rebate)
  • NHS referral – households identified as low-income and vulnerable, with an occupant whose health conditions may be impacted further by living in a cold home

This is just a brief overview of the eligibility, please see the central and south Lincolnshire councils' statement of intent [pdf / 541 KB] for the full eligibility criteria.
