Fuel Watcher Report:UK drivers see cheapest prices in Northern Ireland
The cost to fill a typical family car has fallen by £0.33 over the last 7 days.
What This Means For You
UK average petrol prices currently stand at 155.1p per litre, while diesel averages 176.0p per litre. Over the latest 24-hour comparison, petrol is broadly unchanged over the last 24 hours, while diesel has fallen by 0.1p per litre over the last 24 hours.
Northern Ireland is currently the cheapest region for petrol at 148.7p per litre, while Scotland is the most expensive at 157.1p per litre, a gap of 8.4p per litre. For diesel, Northern Ireland is cheapest at 166.6p per litre and Scotland is most expensive at 176.8p per litre, a gap of 10.2p per litre.
A typical family car with a 55-litre petrol tank currently costs around £85.30 to fill using the UK average petrol price. That is down £0.33 compared with the oldest available point in the 7-day reporting window. Driving 100 miles in a typical family car is estimated at about £17.63 in petrol or about £16.00 in diesel, based on the report assumptions.
Petrol and diesel are moving in different directions against the 24-hour comparison point, so the short-term picture is mixed rather than clearly rising or falling. Brent crude is currently $87.33, which provides useful context but may not feed through to forecourt prices immediately.

Brent crude oil context
Brent crude helps indicate the direction of future fuel costs. While changes do not affect pump prices immediately, sustained movements in oil markets can influence petrol and diesel prices over the following days and weeks.

Where your fuel money goes
Fuel prices include product cost, Fuel Duty and VAT.
Petrol
At the current average price, around 51% (£0.79) of each litre of petrol is tax.
Diesel
At the current average price, around 47% (£0.82) of each litre of diesel is tax.
This breakdown uses the latest UK average prices and updates automatically as pump prices change. Fuel Duty is currently fixed at 52.95p per litre. VAT is charged at 20% on the pre-VAT total, so the VAT element rises and falls with the pump price.
