# Oil dearer, pump cheaper — and the other way round



Last updated 22 September 2026.
Figures refresh every night. [How each figure is worked out](/methodology/).




As of 21 September 2026, only **61.5p of the UK's 172.0p litre of petrol is crude oil** — about 36%. 52.95p is fuel duty and 28.7p is VAT, both of which barely move with the oil price, and 28.9p is refining, distribution and the forecourt's margin. That is why a large percentage fall in Brent produces a much smaller percentage fall at the pump. Crude is Brent converted at that week's exchange rate; the pump price is the DESNZ weekly average.

The amber bands are tax. They are close to flat over time for duty, and move with the price for VAT.
The blue bands are cost: crude, and the residual that covers refining, shipping, storage, distribution
and the forecourt.





## Has oil ever been dearer than today while petrol was cheaper?



Yes, and the site checks for it automatically every night. Two versions of the test: one comparing the
barrel price in dollars, which is how the oil market quotes it, and one comparing crude converted into
pence per litre, which takes the exchange rate out and leaves duty, VAT and the margin to explain the rest.



### Measured in dollars a barrel



- 9 June 2008
In June 2008 Brent was $134 against $131 now, yet petrol was 116.9p against 172.0p, 55.1p cheaper: crude adds 18.7p, duty adds 2.6p, VAT adds 11.3p, the refining and retail margin adds 22.6p. Sterling accounts for about 20.4p of the crude difference.




### Measured in pence a litre



- 7 March 2022
In March 2022 Brent was 61.8p a litre against 61.5p a litre now, yet petrol was 152.9p against 172.0p, 19.1p cheaper: duty takes off 5.0p, VAT adds 3.2p, the refining and retail margin adds 21.1p.




The difference between the two lists is the exchange rate. Brent is priced in dollars, so a weaker
pound raises the cost of a litre even when the barrel price has not moved.





## When has the margin run unusually wide?



The margin here is a residual: whatever is left after crude, duty and VAT. 157 weeks in
the series sit more than 1.5 standard deviations above their own 52-week rolling average. A wide margin
has several innocent explanations — refinery outages, the lag between buying a cargo and selling it,
and crack spreads that the crude benchmark does not capture — so this flags and measures, and stops there.

**The numbers behind this chart**




| Episode | Weeks | Peak margin | Standard deviations above average |
| --- | --- | --- | --- |
| 3 Aug 2026 to 31 Aug 2026 | 5 | 38.7p | 1.93 |
| 1 Jun 2026 to 6 Jul 2026 | 6 | 38.5p | 2.56 |
| 17 Nov 2025 to 22 Dec 2025 | 5 | 32.2p | 2.25 |
| 13 Oct 2025 to 20 Oct 2025 | 2 | 30.8p | 2.39 |
| 27 May 2024 to 3 Jun 2024 | 2 | 32.1p | 1.92 |
| 13 Jun 2022 to 15 Aug 2022 | 10 | 45.0p | 3.63 |
| 28 Mar 2022 to 25 Apr 2022 | 4 | 34.6p | 3.05 |
| 25 Oct 2021 to 3 Jan 2022 | 11 | 30.3p | 3.68 |

## Do pump prices rise faster than they fall?



**Half of a rise in crude reaches the pump in about 2.8 weeks; half of a fall in about 3.0 weeks. On this measure rises and falls reach the pump at much the same speed. In the week of the move itself about 10% of a rise shows up at the pump against about 8% of a fall. Over the full 8-week window a 10p move in crude is associated with about 13p at the pump on the way up and about 11p on the way down. Both exceed 10p because refining and retail costs tend to move with crude as well, so this is the response to a crude move, not the crude cost alone.**



Estimated from 1153 weeks of data with an eight-week lag structure, fitting weekly
changes in the pump price to the positive and negative parts of weekly changes in crude. The fit
explains 61% of the week-to-week variation. This is one specification on
national weekly averages, not a finding about any particular retailer.

## Work out the pump price from the barrel price



A barrel is 158.987 litres. Move the sliders to see what a given oil price,
exchange rate and margin would mean at the pump. The starting values are the latest actual figures.



Brent crude, $ a barrel

$131


Pound in dollars

$1.337


Refining and retail margin, p a litre

29p


172.0pEstimated pump price
61.5pCrude oil in each litre
81.6pTax per litre
47%Tax share of price









Duty of 52.95p and VAT at 20% are applied
to whatever you choose. Refiners buy cargoes weeks ahead, so real pump prices lag the oil market.






## How this is worked out



Crude is Brent converted at that week’s exchange rate: dollars per barrel divided by 158.987 litres, divided by the pound in dollars, times 100. VAT is the share of the pump price the rate implies, duty is the rate DESNZ publishes for that week, and the margin is whatever is left: refining, shipping, storage, distribution and the forecourt. It is a residual, so anything the Brent benchmark misses, such as biofuel content or refinery timing, lands in it.

## Common questions


How much of the petrol price is the oil price?
About 61.5p of a 172.0p litre, or 36%, as of 21 September 2026.Why does petrol not get cheaper when oil falls?
Because most of the price is not oil. 52.95p is fixed duty and 28.7p is VAT, so a 10% fall in crude is only about 3.6% off the pump price before anything else changes.Do pump prices rise faster than they fall?
Half of a rise in crude reaches the pump in about 2.8 weeks; half of a fall in about 3.0 weeks. On this measure rises and falls reach the pump at much the same speed. In the week of the move itself about 10% of a rise shows up at the pump against about 8% of a fall. Over the full 8-week window a 10p move in crude is associated with about 13p at the pump on the way up and about 11p on the way down. Both exceed 10p because refining and retail costs tend to move with crude as well, so this is the response to a crude move, not the crude cost alone.
