The Free Boiler Grant is part of the ECO4 scheme, where the government provides boiler replacement grants to replace back boilers for free. Homeowners and private tenants on qualifying benefits can upgrade their heating system having a gas boiler or heat pump. The grant covers the full cost of installation with no upfront payment required.
To be eligible for a free boiler under these grants, you must receive qualifying benefits like Universal Credit, Pension Credit, or have a low household income. Your existing boiler should be inefficient or over 7 years old, and your property must have an EPC rating of D or below.
The ECO4 scheme covers modern A-rated condensing boilers, combi boilers, system boilers, and in some cases, air source heat pumps. All installations are carried out by Gas Safe registered engineers to ensure safety and compliance.
Once approved, the survey and installation typically takes 4-6 weeks. The actual installation usually takes 1-2 days, depending on your property type and the complexity of the work required.
For eligible households, the boiler replacement is completely free through the ECO4 scheme. There are no upfront costs, hidden fees, or monthly payments. However, some households may need to contribute a small amount depending on their specific circumstances.
