We found the Carbon Trust’s interest free loan scheme very beneficial to our LED replacement scheme. The process was extremely easy to follow, very efficiently ran, and we were aided each step of the way by the team. Without the support of the Energy Efficiency Loan Fund we would not have been able to implement our project. We would be delighted to recommend this scheme to any business looking to invest in reducing their carbon footprint.

Without support from the Carbon Trust, this project would not have gone ahead.
