What's in the price per litre?
The price of petrol and diesel also includes duty at
56.55ppl (2020 rate) and
58.42ppl (super unleaded) as well as GST
So for example, if the forecourt price of unleaded petrol is
£1.05 per litre the GST element is 5p, the duty is 56.55p and the
retail price is 45.45p.
For heating oil, if the price is 50p per litre, GST is 2.4p and
therefore the price of the product is 47.6p per litre.
