If you've ever filled up on a motorway and then spotted cheaper fuel in town, you'll know that location matters when it comes to fuel prices. But the differences go far beyond individual stations - there are significant regional variations across the UK.
The Cheapest Regions
Based on average prices in early 2026:
1. Northern Ireland
Average petrol: 129-130p per litre
Northern Ireland consistently offers the cheapest fuel in the UK, thanks to: - Proximity to the Republic of Ireland (competitive cross-border pricing) - Lower average land costs for forecourts - Strong supermarket competition
2. North East England
Average petrol: 130-131p per litre
The North East benefits from: - Major refineries at Teesside - High concentration of supermarket forecourts - Lower operating costs than southern regions
3. Scotland (Urban Areas)
Average petrol: 131-132p per litre
Scottish cities like Glasgow and Edinburgh see competitive pricing, though rural areas can be significantly more expensive.
The Most Expensive Regions
1. London
Average petrol: 134-137p per litre
The capital's high prices reflect: - Premium real estate costs for forecourts - Congestion zone proximity - Lower competition in some areas
2. South East England
Average petrol: 133-135p per litre
Higher costs of living and land values push prices up.
3. Rural Scotland and Wales
Average petrol: 138-145p per litre
Remote areas face: - Higher delivery costs - Less competition - Longer distances from refineries
Motorway vs High Street
The difference between motorway services and local forecourts can be stark:
| Location | Typical Petrol Price |
|---|---|
| Supermarket | 130-133p |
| Urban forecourt | 133-137p |
| Motorway services | 145-160p |
The premium for motorway fuel can be 15-25p per litre - that's £7.50 to £12.50 extra on a 50-litre fill.
Tips for Finding Cheap Fuel
1. Use Price Comparison Tools
Our fuel price map shows real-time prices near any UK location. You can filter by fuel type and sort by price.
2. Fill Up at Supermarkets
Asda, Tesco, Sainsbury's, and Morrisons consistently offer the lowest prices. Costco is even cheaper if you're a member.
3. Plan Ahead on Long Journeys
Check prices along your route and fill up where it's cheapest - even if that means stopping earlier or later than planned.
4. Avoid Motorway Services
Unless you're running on fumes, exit the motorway and find a local station. Even a 5-minute detour can save you £10+.
5. Use Loyalty Cards
Most supermarkets offer points on fuel purchases. While the savings are modest (0.5-1p per litre equivalent), they add up over time.
Price Checking Made Easy
The new UK Government Fuel Finder scheme requires all forecourts to report prices within 30 minutes of changes. This means price comparison tools like ours are more accurate than ever.
Don't pay more than you need to - a few minutes of research can save you hundreds of pounds per year.
