The Electric Storage Heater Grant is a UK government-backed scheme (under ECO4) designed to replace old, inefficient electric storage heaters with modern, high‑heat retention units often free of charge for qualifying households. These upgrades utilize cheaper off‑peak tariffs (e.g., Economy 7) to store heat at night and release it during the day offering a smarter, greener way to stay warm.
Most frequent questions and answers
You may qualify if you are a UK homeowner or private tenant (with landlord permission), your property has electric storage heating, and it has an EPC rating of E, F, or G—homes with a D rating may also qualify subject to funding limits. Additionally, you must receive qualifying income-based benefits such as Universal Credit, Pension Credit, or Child Tax Credit; or you may be eligible through your local authority under the ECO Flex pathway.
