The Journey from Crude Oil to the Pump
It's a common frustration for UK drivers: the price of crude oil falls, but the price at the pump barely budges. This isn't just your imagination; there are structural reasons for this, and it mostly comes down to tax. The price you pay is built from four main blocks: the cost of crude oil, the refining margin, retail costs, and government taxes (Fuel Duty and VAT).
At Calculator Site, we believe in empowering consumers with clear information. The two biggest components of the UK fuel price, aside from the fuel itself, are Fuel Duty and Value Added Tax (VAT). Fuel Duty is a fixed tax levied by the government on every litre, acting as a huge price floor. VAT is a 20% tax applied to the total price, including the Fuel Duty. When the crude oil portion of the price falls, these large tax elements remain, cushioning the drop.
The Exchange Rate Effect
Crude oil is traded globally in US Dollars. This means a weaker Pound (a lower GBP/USD rate) makes it more expensive for UK refineries to buy oil, leading to higher pump prices even if the dollar oil price is stable. Our calculator's sensitivity matrix is perfect for exploring this exact relationship.
