Professor Mark Hart of the Enterprise Research Centre speaks with Liz Barclay to explain why micro-businesses are far more important to the UK economy than policymakers recognise. Drawing on decades of research, he reveals how these smallest firms quietly drive job creation, sustain local economies and contribute billions in long-term growth, despite often being overlooked in favour of “scale-ups” and high-growth firms.The conversation challenges current policy thinking, arguing that an overemphasis on a narrow group of businesses risks ignoring the real engine of the economy. Mark highlights evidence showing that many micro-enterprises grow steadily over time, becoming significant employers without relying on government intervention.He also addresses the barriers these businesses face, including access to finance, skills and consistent policy support.This episode simplifies complex research into practical insights, making clear why recognising and supporting micro-businesses is essential for a more balanced, resilient and inclusive UK economy.
