Energy Efficiency Loan Fund (Wales)

Interest-free loans for energy efficiency and renewable energy projects in Wales.

Closure notice

The Carbon Trust is proud of the significant support provided to Welsh businesses since 2003, with over 700 loans provided and notable investment in energy efficiency and energy cost savings.

Over the last few years, we have seen a slow but consistent decline in loan applications. In response to this, we have taken the difficult decision to close down the Energy Efficiency Loan Fund in Wales. As of Wednesday 31 March 2021, we are no longer taking new applications for loans, and the Energy Efficiency Loan Fund has closed.

While no new loan applications are being accepted, we will continue to manage any outstanding loans until they are fully repaid.

The Carbon Trust is committed to supporting businesses in Wales with the transition to a low carbon economy. You can find a range of free tools, guides and resources at
