UK agricultural input price index: motor fuels

Understanding UK agricultural input price index: motor fuels

This index measures purchase prices paid by farm businesses across the United Kingdom for liquid petroleum products consumed by mobile agricultural machinery, specifically tractors, harvesters, self-propelled sprayers, and on-farm transport vehicles. The scope covers bulk deliveries of red diesel and standard transport fuels utilised directly in field operations, while excluding lubricants, household heating oils, and private vehicles. Unlike stationary energy inputs such as grid electricity, this series reflects highly volatile global petroleum commodity markets and localised distribution charges absorbed immediately by producers.

Seasonality in this series typically mirrors intense periods of field activity, notably spring cultivation and autumn harvesting windows when fuel burn peaks across holdings. Early figures often undergo administrative revision as fuel supplier returns and rebate adjustments are fully incorporated into the rolling index calculations. Analysts comparing this series with broad transport fuel inflation benchmarks must account for the specific duty reliefs and agricultural tax structures applicable to specialised red diesel supplies.
