The profit taken from diesel per litre at the pumps increased by 14.5% to 11.06p per litre over the last two months, according to new analysis from FairFuelUK.
Data on profits per litre was taken from the FairFuelUK Supporter Forum, RAC Foundation, Portland Fuel and PetrolPrices.com.
FairFuelUK is a public affairs campaign that fights for lower fuel duty and more transparent pricing at the pumps.
It argues that despite falling wholesale and oil prices, UK drivers aren’t seeing those reductions reflecting at the price at the pump.
The profit margin on unleaded has risen at a much sharper rate, 156%, since August.
Although diesel and petrol are taxed the same by the Treasury, historically diesel has been more expensive than petrol, as domestic refineries have struggled to meet demand.
This has forced the UK to import diesel from other countries at a greater rate than petrol.
Howard Cox, founder of the FairFuelUK Campaign, said the Government is continuing to ignore the problem of lack of transparency at the pumps.
He said: “It must be halted with the immediate creation of an independent price supervisory body, we call PumpWatch.”
