Many small and medium enterprises (SMEs) are managed by owners, founders, or small leadership teams. The UK government’s Help to Grow Management Programme (HtGM) aims to improve SME growth through leadership and management skills training to increase firm level productivity. The government’s independent evaluation reports for the HtGM programme show that its aims were broadly met, but there is no empirical research that has reviewed the programme. To address this gap, 46 HtGM programme completers were interviewed on their perception of the HtGM outcomes. Data were analysed using thematic analysis and compared to the government’s evaluation reports. This study’s findings show that a variety of programme activities developed skills, knowledge, and management practices, resulting in improved confidence to lead and drive growth. The analysis adds depth to our understanding how this was achieved from the programme, highlighting the benefits of mentoring, networking and cross-collaboration. Follow-up support is recommended for the growth action plan (GAP).
