Two drivers filling up on the same day in the same country can pay wildly different prices. A litre of petrol in parts of Scotland costs 126p. In central London, it's 160p. That's a 34p gap — or £17 extra on a single tank. Where you live has become one of the biggest factors in what you pay at the pump.
The Price Gap at a Glance
Based on February 2026 data, the UK's regional fuel price spread is stark. Here's how the main regions compare:
That 19p regional spread is bad enough. But add in the type of station — supermarket vs branded vs motorway — and the gap widens to over 40p per litre in extreme cases. On a 55-litre tank, that's the difference between paying £69 and £91.
Region by Region Breakdown
Here's how average petrol and diesel prices compare across the UK's main regions in February 2026:
The pattern is clear: prices rise as you move south and east, with London sitting firmly at the top. But why?
Why Prices Vary So Much
Fuel duty and VAT are identical everywhere in the UK. The wholesale cost of fuel is broadly similar too — refineries supply the whole country. So the regional gap comes down to four factors:
Operating Costs
Rent, rates, and wages are dramatically higher in London and the South East. A forecourt in central London pays many times more in property costs than one in Newcastle. Those costs get passed directly to the pump price.
Competition Density
Areas with more supermarket forecourts see lower prices. Scotland and the North East have strong supermarket coverage, creating intense price competition. Rural areas with fewer stations have less incentive to compete.
Delivery Distance
Fuel is transported from refineries and terminals by tanker. Remote and rural areas — parts of Wales, Scotland, and the South West — face higher delivery costs that add 1–3p per litre to the final price.
Brand Mix
London has a higher concentration of premium branded stations (Shell, BP, Esso) relative to supermarket forecourts. Branded stations typically charge 4–8p more per litre than supermarkets for the same base fuel.
The Rural Penalty
Rural drivers face a double hit: higher prices and longer distances, meaning they burn more fuel just getting to work or the shops. A rural driver in mid-Wales might pay 5p more per litre than someone in Manchester — and use 30% more fuel per week due to longer journeys. The annual cost difference can exceed £400.
Supermarket vs Branded: The Station Type Gap
Where you fill up matters as much as where you live. Across every region, the pattern holds:
- Supermarket forecourts (Asda, Tesco, Sainsbury's, Morrisons) — 128–133p petrol, 137–142p diesel. Typically 4–8p below the national average.
- Branded stations (Shell, BP, Esso) — 132–138p petrol, 141–147p diesel. Higher margins fund loyalty schemes and forecourt amenities.
- Motorway services (Moto, Welcome Break, RoadChef) — 148–170p petrol, 155–178p diesel. Captive audience pricing at its most extreme. See our full analysis of why motorway fuel costs more.
A supermarket in Scotland could be selling petrol at 126p. A motorway service station in the South East could charge 170p. Same fuel, same day — 44p difference. That's £24 on a single 55-litre tank.
The Fuel Finder Effect
The government's Fuel Finder scheme, launched on 2 February 2026, is designed to tackle exactly this problem. All UK forecourts must now report their prices within 30 minutes of any change, making the postcode lottery visible to every driver.
Early data suggests the scheme is already having an impact. When prices are transparent, stations in competitive areas face pressure to match their neighbours. The government estimates the scheme could save the average household £40 a year — but only if drivers actually use the data to compare.

What You Can Do About It
You can't move house to save 10p a litre, but you can make smarter choices within your area:
- Compare before you fill — Use Fuelwise to check prices in your area. Even within a single town, the difference between the cheapest and most expensive station can be 10–15p per litre.
- Prioritise supermarket forecourts — They're consistently the cheapest option in every region. If you have an Asda, Tesco, Sainsbury's or Morrisons nearby, start there.
- Fill up before the motorway — Motorway prices are 17–38p above supermarket rates. Always plan your fuel stops before hitting the M-roads.
- Use loyalty schemes — If you're stuck with a branded station, at least earn something back. Check our loyalty card comparison to find the best value schemes.
- Time it right — Some stations are cheaper on certain days. Read our analysis on the best time to fill up.
The Bottom Line
The UK's fuel price postcode lottery isn't going away. Operating costs, competition levels, and delivery distances will always create regional differences. But the gap between what you could pay and what you do pay is entirely within your control.
With the fuel duty increase coming in September, every penny per litre matters more than ever. Drivers who compare prices consistently save £200+ a year compared to those who fill up wherever is convenient. The data is there — use it.
