Government Intuitive

If you’re a low-income household or claiming benefits, this is your shot to slash bills, reduce emissions, and future-proof your home – at zero cost to you.
About Scheme
Instead of short-term fixes, the ECO4 Scheme delivers full-scale retrofit upgrades – targeting outdated heating systems, poor insulation, and low EPC ratings. With over 810,000 energy-saving measures installed so far, it’s helping thousands of UK homes become warmer, cheaper to run, and future-ready.
And best of all – it’s 100% free for eligible households.
By installing modern, energy-efficient condensing boilers, the ECO4 Scheme significantly improves the EPC rating of your home. Condensing boilers are highly efficient, capturing and reusing heat that would otherwise be wasted. This upgrade reduces energy consumption and carbon emissions, leading to a better EPC rating and lower energy bills.
Eligible Old Heating Systems
Under the government grants, only outdated heating systems are replaced with high-efficiency condensing boilers or heat pumps. The primary purpose is to boost your home EPC rating to above D. Apply for free replacement if you have any of these list of in-efficiently old heating systems:

EPC
Over 19 million UK homes are still stuck at an EPC rating of D or worse. Yours doesn’t have to be one of them.
If your home has an EPC rating of D, E, F, or G, you’re exactly who the ECO4 scheme was designed for. These properties are harder to heat, more expensive to run, and waste more energy – and the UK government wants to fix that.
With a 100% free retrofit, many homes have jumped from an EPC of F or G to C or even B – just by upgrading their boiler, insulation, radiators, TRVs, and heating controls.
Under the ECO4 Scheme, inefficient boilers are replaced with high-efficiency condensing boilers. The types of boilers eligible for replacement include:
The ECO4 Scheme is available from April 2022 until March 31, 2026. Be sure not to pass up this opportunity for a completely FREE upgrade of your home's heating system.
