Small business energy suppliers in the UK serve micro-businesses and SMEs with tailored tariffs and account management. Key suppliers include Octopus Business, E.ON Next Business, EDF Business, British Gas Business and Opus Energy. All must be Ofgem-licensed. The Energy Ombudsman handles unresolved complaints after 8 weeks. Ofgem's Business Energy Code of Practice applies to all suppliers serving micro-businesses (Ofgem, Energy Ombudsman, 2026).
