What is the ECO4 Scheme?

UK Government ECO4 Scheme Explained

The UK government introduced The Energy Company Obligation (ECO) scheme to tackle fuel poverty, rising energy and heating costs, and climate change. This government ECO scheme is administered through Ofgem and has been through 4 different iterations, and the latest version called ECO4 has £4 billion of funding for eligible applicants. The great news is you could be eligible for an ECO4 grant today, just use our free grant checker to see if you qualify.

What is the ECO4 Scheme?

The UK government has committed to Net Zero by 2050, and to support this target a number of energy efficiency grant schemes have been legislated.

The good news is that if you are eligible for an ECO4 grant it is likely any heating upgrades you receive will be fully paid for by the energy companies. The list of main heating measures covered under the ECO4 scheme include:

  • Boiler Upgrades
  • Air Source Heat Pumps with Solar Panels
  • Electric Storage Heater Upgrades with Solar Panels
  • Insulation Measures (roof insulation, loft insulation, cavity wall insulation, internal wall insulation and more)

How much funding can I access via the ECO4 Scheme?

The total funding pool available for the ECO4 scheme is £4 billion, and the amount of funding for individuals will vary depending on a number of factors (see further details below). The good news is that Energy Saving Genie has designed a simple quiz to determine your eligibility for an ECO4 grant (it only takes as little as 23 seconds!). In most cases, applicants can access from £7,000 up to £20,000 or more of funding to install energy saving heating and insulation upgrades.

Who is eligible for the ECO4 Scheme?

The eligibility rules for the ECO4 scheme can seem quite confusing, which is why Energy Saving Genie can do the checking for you. Our free grant checker will ask you for information to help best determine your eligibility to grants. The Energy Performance Certificate (known as EPC) rating of your property determines if you are eligible for an ECO4 grant and a minimum improvement needs to be made to your property (sometimes referred to as the minimum uplift). The bigger the improvement on your EPC rating, the more ECO4 grant funding your property will receive.
