Petrol prices in the UK are slightly lower than similar European countries such as France and Germany, with £1.44 and £1.47 per litre respectively. Diesel in the UK costs, on average, £1.40 per litre as of May 2025. This is similar to the most paid across the EU, with Denmark and Ireland paying 1.43 and 1.42 per litre respectively.

There is no VAT charged on avtur for international flights in accordance with the
Convention on International Civil Aviation, although commercial operators do pay
Air Passenger Duty.
Avgas, used by some smaller planes, was taxed at half the rate of road petrol for all users until October 2008, when the reduced rate was limited to commercial flying. A minority of light planes use standard road petrol and pay tax at the normal rate.
Buses The
Bus Service Operators Grant provides a
fuel duty rebate to local bus service operators (but not for express coach which receives no rebate). As of April 2010 the rebate was £0.43 for diesel, £0.2360 for road fuel gas other than natural gas and 100% for biodiesel and bioethanol. Additional rebates are available for increasing fuel efficiency, low carbon emission vehicles and equipping vehicles with Smartcards and GPS tracking equipment. In 2001 it was proposed that long-distance scheduled coach services should receive the rebate in return for offering half-price fares to older and disabled passengers.
Construction and farm vehicles Certain registered construction and farm vehicles are allowed to use 'red diesel' which includes a
fuel dye and has a significantly reduced tax levy compared to normal road fuel. There are restrictions around the types of vehicle it can be used in and the purposes it can be used for, and there are heavy fines for misuse.
Trains Diesel used for passenger trains is zero-rated for VAT. Trains are allowed to use red diesel and rebated biodiesel, as they are included in the category of "Any vehicle designed to be operated on a railway" and in the list of exempted machines. As a result, fuel for passenger services is just taxed at the marked gas oil (red diesel) rate. To incentivise the use of cleaner fuels in trains, the duty was reduced from 53p to 8p for blends of red diesel and biodiesel used in approved pilot schemes in the
Budget 2007. ==See also==
