The Department of Trade and Industry (DTI) was a UK government department responsible for trade, business, and industrial policies. In 2007, it was replaced by the Department for Business, Enterprise, and Regulatory Reform (BERR) and the Department for Innovation, Universities, and Skills (DIUS). Those then merged to form the Department for Business, Energy, and Industrial Strategy (BEIS). In 2023, the BEIS was split into the Department for Business and Trade (DBT), the Department for Energy Security and Net Zero (DESNZ), and the Department for Science, Innovation, and Technology (DSIT).
