ECO grants in Wales

About the ECO grant Scheme
Although ECO is a government-led scheme to promote energy efficiency, ECO 4 grants in Wales are not funded by the Welsh or UK governments. The “Big Six” main energy providers are responsible for covering the expense. British Gas, Scottish Power, EDF, SSE, E.ON, and NPower are the main six.
UK energy providers are required to offer incentives under the grant programme for energy-saving measures in the following three categories: heating, insulation, and low-carbon technologies like solar panels and air source heat pumps.
These companies are required by the government to contribute funds for grants in order to raise the energy efficiency of millions of homes nationwide.
The government’s plan to meet carbon emission targets and lessen the effects of the current cost of living crisis includes ECO4. This can be done by increasing Wales’s thousands of properties’ energy efficiency.
The best way to assist vulnerable and low-income households in overcoming fuel poverty is to upgrade domestic central heating systems and insulation
