Quick fag packet calculation on the extra government income from the recent increases in diesel price to non business private customers (Putting the 53p per litre of duty aside - as that number is a flat rate and they always get that and quantities of diesel used remain relatively stable.)
So let's just concentrate on the VAT tax take.
The average price of diesel in 2026 (post Trump deciding to give Iran a spanking) was £1.40 per litre. So the government were making an income of around 0.28p per litre of that in VAT.
Skip forward to yesterday and average price of diesel was £1.82 per litre. So the government were making an income of 0.38p per litre in VAT yesterday. Prices are set to rise a lot further too.
Thats a 36% increase in VAT income from private diesel car drivers !!
The average car tank hold 60 litres of fuel. So prior to the Iran conflict every time a tank was filled the government took around £16.80 in VAT.
Yesterday that VAT income on filling a tank rose to £22.80 !
If you add the 0.53p of duty also taken - the total tax given to the government per tank (excluding road tax) has reached an absolutely staggering £54.30 from every private diesel car driver.
In comparison - I charge my electric car at night at the cheap rate. To fill the battery and get a range of 350 miles costs me a total of £4.55. Of that the government takes a VAT rate of 5%. So they get a grand total of about 0.23p.
God bless Elon Musk.
