About the ECO4 Scheme
The most recent step of the Energy Company Obligation policy that has been introduced by the UK Government is known as ECO4, and it is a policy that obliges large energy suppliers to finance domestic energy efficiency measures. The aim of the scheme is to ensure homes are warmer, healthier and less expensive to heat especially the low-income earners and those living in properties that are energy inefficient.
ECO4 has served hundreds of thousands of households since its introduction, which has enabled them to save money and mitigate the national carbon emissions. Ofgem regulates the programme and all installations are to be corresponding to the government standards and quality requirements.
