What is fuel duty?
Understanding the biggest single component of the price you pay at the pump.
Fuel duty is a tax included in the price you pay for petrol, diesel, and other fuels. It is currently set at 52.95p per litre for both petrol and diesel. The rate is set by the Chancellor of the Exchequer and applies uniformly across the UK.
In addition to fuel duty, VAT at 20% is charged on the total price at the pump (including the duty itself). This means the government effectively taxes the tax, a practice often referred to as “tax on tax”.
Fuel duty has been a significant source of government revenue for decades. Changes to the rate are usually announced in the Budget and can have an immediate impact on pump prices across the country.

Why do fuel prices vary by area?
Understanding the factors that drive local price differences across the UK.
Fuel prices can vary by as much as 20-30p per litre between the cheapest and most expensive stations in the same area. Several key factors determine the price you pay at any given forecourt.
Local Competition
Areas with more stations compete more aggressively on price, driving costs down for drivers.
Terminal Proximity
Stations closer to fuel distribution terminals have lower delivery costs, often reflected in cheaper prices.
Rural vs Urban
Rural stations face higher delivery costs and lower volumes, leading to higher prices per litre.
Brand vs Independent
Independent retailers often undercut major brands, while supermarkets use fuel as a loss-leader.
