Where are Drivers Paying the Most and Least?
Regional prices reveal significant differences in what UK drivers pay at the forecourt. Here are all regions ranked cheapest to most expensive for petrol this week:
| Region | Avg Petrol (E10) |

Drivers in South East pay 7.5p/litre more than those in Northern Ireland. On a 50-litre fill-up, that is £3.75 per tank, and for someone filling up once a week, around £195 extra per year.

Supermarkets vs. The Rest
Supermarket forecourts remain the go-to for value-conscious drivers. This week, the average supermarket petrol price is 155.7p/litre, 3.1p cheaper than the average non-supermarket station at 158.7p.
On a 50-litre fill that translates to a £1.53 saving at the supermarket pump.
For diesel, supermarkets offer an average saving of 3.1p/litre (189.1p vs 192.2p elsewhere).
Petrol (E10) Prices by Brand
Average petrol prices ranked cheapest first, for brands with at least 15 stations reporting:

| CIRCLE K | 152.5p | 18 |

Is That Cheaper Station Actually Worth the Drive?
This is where WorthTheDrive differs from every other fuel price tracker. Knowing the cheapest price nearby is only half the story; you also need to know whether the cost of getting there wipes out your saving before you even reach the pump.
At this week’s national average petrol price of 157.7p/litre, here is the maximum round-trip worth making for a typical driver (50-litre tank, a quarter full, 40 MPG):
| Saving vs. your nearest station | Max distance worth driving |
|---|---|
| 1p/litre cheaper | 2.1 miles |
| 2p/litre cheaper | 4.2 miles |
| 3p/litre cheaper | 6.3 miles |
| 5p/litre cheaper | 10.5 miles |
| 10p/litre cheaper | 20.9 miles |
In other words, if you spot a station at 152.7p/litre (5p below the national average), it is worth driving up to 10.5 miles out of your way to get there. Any further and the fuel you burn on the drive costs more than you save.
Diesel drivers: at 191.1p/litre, a 5p/litre saving is worth driving up to 8.6 miles.
These thresholds shift every time prices move, which is why WorthTheDrive recalculates them live using real-time station prices. Enter your postcode at https://worththedrive.co.uk to see exactly which stations near you are genuinely worth the drive.
