Grappling with the transition to electric, vehicle supply shortages and rising prices? Spare a thought for Andrew Miller (pictured).

Chief executive at Motability Operations for the past 20 months, he oversees the biggest fleet in the UK, purchasing, converting and disposing of more than 630,000 vehicles.

Motability Operations accounts for 12% of annual new car registrations and is the country’s highest spender in the conversion and repair markets, as well as being one of its biggest insurers. Fleet issues are multiplied exponentially at this scale.

For more than 40 years, the organisation has managed the Motability Scheme on behalf of charity Motability, which is both customer and regulator. The relationship is founded on fleet dynamics and a customer service proposition, with Miller counting both the charity and the car drivers as his customers.
