What's in the price per litre?
The price of petrol and diesel also includes duty at 45.47ppl
(2017 rate) and 47.29ppl (super unleaded) as well as GST of 5%.
So for example, if the forecourt price of unleaded petrol is
£1.05 per litre, the GST element is 5p and the duty is 45.47p,
resulting in the retail price of the fuel to be 54.53p per
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.
