The Energy Company Obligation (ECO4) Grants scheme

ECO4 is the latest version of the UK Government’s Energy Company Obligation scheme, running until 31 March 2026. It provides funding for energy efficiency upgrades in low-income or poorly insulated properties with low EPC ratings. This includes renewable energy solutions such as heat pumps and solar PV.

Ofgem administers ECO4 on behalf of DESNZ (Department for Energy Security and Net Zero). More information can be found on their website.

Once certified, you’ll need to work with an obligated energy supplier to deliver installations under ECO4. You can find contact details for suppliers, alongside a range of guidance documents and materials, on the Ofgem website.
