Industrial Energy Transformation Fund

The Industrial Energy Transformation Fund (IETF) supports the development and deployment of technologies that enable businesses with high energy use to transition to a low carbon future.

The Industrial Energy Transformation Fund (IETF) is designed to help businesses with high energy use to cut their energy bills and carbon emissions through investing in energy efficiency and low carbon technologies.

The UK government announced £315 million of funding in the 2018 Budget, available up until 2025.

BEIS manages the IETF for England, Wales and Northern Ireland, with £289 million to invest over consecutive application windows split into 2 phases.

BEIS will review key aspects of the Fund design and delivery ahead of future windows to respond to feedback and to ensure the success of the programme. The guidance may change so please visit the relevant page for the current competition.
