Question to the Cabinet Office:

To ask Her Majesty’s Government, when purchasing vehicles for use by government departments, what criteria they apply regarding whether to purchase petrol- or diesel- fuelled cars.

Public sector procurers are required to seek value for money through fair and open competition and Government will always award contracts on the basis of the best value for money for the taxpayer.

Crown Commercial Service manages a framework agreement for the supply of diesel, petrol and electric powered vehicles which Government departments use to meet their vehicle requirements.

Departments decide which fuel is most appropriate based on their individual requirements including whole life costs and may access advice and guidance from Crown Commercial Service as appropriate.
