The Full Story

A plain summary built from the channels that reported this story.

Diesel prices and fuel duty have become a central pressure point before the Budget on 28 October. The focus is on what the Chancellor can do to ease costs for drivers and businesses, because so much of the pump price is tax rather than the underlying fuel.

Fuel duty is charged at a flat rate per litre and stands at about 53p. VAT at 20% is then paid on both the fuel and the duty, so tax is charged on tax. At a diesel price of £2 a litre, about 33p is VAT and 53p is fuel duty. Together, around 86p of every £2 goes in tax.

Fuel duty was due to rise by a few pence in January and March next year. The expectation is that the Chancellor will at least pause those increases. The Liberal Democrats, through Ed Davey, want a 10% cut in fuel duty, from 53p to 43p. That would cost around £2bn, which makes it expensive even though the duty remains high.

The politics are difficult because the VAT treatment of fuel duty is not a Labour policy, but it is now a Labour problem. Conservative chancellors previously paused planned fuel duty rises. Drivers are feeling the cost of living and business costs. Farmers, hauliers and coach operators are affected. Some coach operators say they may have to give back school transport contracts because those deals were agreed at fixed rates before prices surged.

There is also a supply-side weakness. The UK has only four refineries, and one large refinery is undergoing maintenance at the moment. That leaves the country reliant on imports, with the US a key source of diesel. Global shocks, including the Ukraine-Russian war and the Iran-US-Israel conflict, make the UK more exposed than countries with more refining capacity.

The wider political backdrop includes the Prime Minister naming Iran as the chief suspect in an operation on UK soil, after vans were detained near RAF Fairford. The discussion linked that security situation to diesel prices, saying it is one way British voters feel the effects of the Iran war. For the Chancellor, the 28 October Budget is where those cost pressures and tax decisions meet.

Claim
Only on one channel
Ed Davey and the Liberal Democrats propose cutting fuel duty by 10%, from 53p to 43p per litre, at a cost of around a couple of billion pounds.
Fuel duty is about 53p per litre and VAT at 20% is charged on both fuel and fuel duty, meaning at £2 per litre around 86p is tax.

Channel Perspectives

What each channel focused on, with key quotes.

The segment treated diesel prices mainly as a Budget and tax story. It broke down fuel duty and VAT, set out the pressure on the Chancellor before 28 October, and highlighted hauliers, farmers and coach operators. It also tied the issue to UK refinery capacity and to the wider Iran security story, while mixing in lighter banter about the Fiesta.

Key Quotes:
  • “For every two pounds I put in, 33 pence of VAT is part of that two pounds. And what 53p is on fuel duty. Together you're talking about 86p of every two pounds is paid in tax.”
  • “What Ed Davey of the Lib Dems wants to happen is for fuel duty to drop by 10%. So from 53 to 43 that would cost I think a couple of billion pounds.”
  • “There's a lot wider issue which is that the UK is very exposed to shortages in diesel because we have only four refineries now and refining is obviously a key part of the process turning crude oil into diesel and one of those big refineries is undergoing maintenance at the moment.”
