Who Qualify for ECO4 Boiler Grant​

If you are a resident of the UK and you have a non-condensing boiler installed, then it means you are qualified for a free boiler scheme and replacement grant in the UK.
The scheme encourages home owners to replace existing non-condensing / fossil fuel heating boilers with condensing boilers. In other words, If you have an older boiler or have not updated your boiler from 2005, you qualify for a free boiler replacement grant under the ECO4 scheme.
The new condensing boilers ensure low carbon emissions and higher efficiency and maximize cost savings through lower energy bills.
