About Grainger Motor Group

A Family-Run Business Built on Experience

Grainger Motor Group was founded in 2022 by brothers Neal and Harry Grainger, bringing together decades of experience within family-run automotive retailing.

In January 2023, Grainger Motor Group acquired Mantles Group Ltd, continuing the proud legacy of one of Hertfordshire’s longest-established motor businesses. Since then, the group has continued to grow its presence across East Anglia through the expansion of its BYD network, including EMG BYD locations in King’s Lynn, Spalding, and Bury St Edmunds.

Today, Grainger Motor Group continues to invest in the future of electric mobility while maintaining the personal approach, trusted relationships, and high standards that customers expect from a family-owned dealer group.

Our aim is simple:

• Deliver exceptional customer experiences
• Provide honest and knowledgeable advice
• Support customers throughout their ownership journey
• Invest in the future of electric mobility
