Diesel and Petrol: Prices

Question

To ask the Secretary of State for Energy Security and Net Zero, what estimate he has made of the contribution of net zero-related costs to the retail price per litre of (a) petrol and (b) diesel.

Answer

There are no dedicated Net Zero levies on petrol or diesel in the UK.

The cost of fuel is influenced by a range of factors. As oil is a globally traded commodity, disruptions or uncertainty in any region can influence prices in the UK until global markets stabilise.

Nonetheless, we have taken several measures to protect drivers. The Chancellor has frozen fuel duty since this Government came to office, extending the 5p fuel duty cut until September. We have also implemented Fuel Finder, which my Department’s analysis suggests could save households that own a car around £40 per year on average.
