The Department for Business and Trade (DBT) is a UK government department formed in 2023 following the merger of the Department for Business, Energy and Industrial Strategy (BEIS) and the Department for International Trade (DIT). The merger consolidated responsibility for business policy, trade promotion, and export support under a single ministerial roof, reflecting a political judgement that commercial diplomacy and domestic industrial policy are better coordinated than separated.

DBT's core remit spans trade negotiations and agreements, inward investment attraction, export finance facilitation, and the regulatory environment for UK businesses. It houses bodies including the Office for Investment and works alongside UK Export Finance, the government's export credit agency. The department is also the primary interlocutor for businesses engaging with government on regulation, competition policy, and market frameworks.

For senior operators and founders, DBT is the principal government counterpart on anything touching cross-border commerce or significant inward investment. Its trade policy decisions shape tariff schedules, rules of origin, and market access conditions that affect supply chains directly. Watching how DBT prioritises bilateral trade relationships, particularly post-Brexit agreements with non-EU partners, offers a reasonable signal of where government sees future growth corridors for UK business. The department's appetite for regulatory reform, or the absence of it, is equally instructive for operators in regulated sectors.
