Regional Fuel Price Report – July 2026
Fuel prices across the UK continue to show significant regional variation this month. In July 2026, the national average for petrol (E10) sits at 154.2p per litre, while diesel (B7) averages 178.8p per litre.
Understanding these regional differences is essential for drivers looking to cut monthly fuel costs — a 6p spread between regions translates to over £3 per 55-litre fill-up, and considerably more over a full year of driving.
National Overview
Based on the latest official UK Government Fuel Finder data, petrol has eased slightly compared to June, dropping from 156.1p to 154.2p per litre. Diesel has seen a more notable decline, falling from 187.9p to 178.8p.
For a typical 55-litre family car, a full petrol tank now costs approximately £84.81, while a diesel fill-up costs around £98.34.
These modest reductions offer some relief, but the regional picture remains uneven. For a full analysis of what's driving these trends, see our latest fuel price insights.
Northern Ireland — The Cheapest Region
Northern Ireland remains the most affordable region in the UK for fuel in July 2026, continuing a long-running trend driven by strong supermarket competition and lower distribution costs.
- Average petrol: 149.7p per litre
- Average diesel: 174.3p per litre
- Cheapest city: Belfast — petrol 148.9p, diesel 173.1p
- Most expensive city: Derry/Londonderry — petrol 151.2p, diesel 176.0p
The gap between Northern Ireland's cheapest and most expensive cities is just 2.3p for petrol — the narrowest spread of any UK region, reflecting a consistently competitive local market.
North of England
The North shows petrol prices slightly above the national average, with diesel tracking close to the UK mean.
- Average petrol: 153.1p per litre
- Average diesel: 177.5p per litre
- Cheapest city: Newcastle — petrol 151.4p, diesel 175.8p
- Most expensive city: Carlisle — petrol 155.6p, diesel 179.2p
Newcastle benefits from a dense cluster of supermarket forecourts, which helps keep prices competitive. More rural parts of Cumbria and Northumberland see higher averages due to reduced competition and longer distribution routes.
Midlands
The Midlands sits broadly in line with national averages, with a moderate spread between its cheapest and most expensive cities.
- Average petrol: 154.4p per litre
- Average diesel: 179.1p per litre
- Cheapest city: Nottingham — petrol 152.6p, diesel 177.3p
- Most expensive city: Shrewsbury — petrol 156.2p, diesel 180.8p
Nottingham's competitive pricing reflects strong supermarket presence, while Shrewsbury's more rural hinterland pushes prices upward, particularly for diesel.
South of England — The Most Expensive Region
The South is the UK's most expensive region for fuel, driven by higher operating costs, premium-branded stations, and strong demand across the South East.
- Average petrol: 157.8p per litre
- Average diesel: 182.6p per litre
- Cheapest city: Southampton — petrol 155.1p, diesel 179.8p
- Most expensive city: London — petrol 159.4p, diesel 184.7p
London remains the most expensive major city in the UK for both petrol and diesel. High urban operating costs, limited forecourt competition in central areas, and premium positioning all contribute. Drivers in the capital can save meaningfully by comparing stations — check Tesco forecourt prices for typically lower options.
Wales
Wales shows moderate prices overall, but with one of the widest internal spreads, reflecting the contrast between urban south Wales and rural mid and north Wales.
- Average petrol: 154.9p per litre
- Average diesel: 179.7p per litre
- Cheapest city: Cardiff — petrol 152.8p, diesel 177.9p
- Most expensive city: Aberystwyth — petrol 157.3p, diesel 182.1p
Cardiff's competitive pricing mirrors the pattern seen in other major UK cities with strong supermarket representation. Rural Welsh towns face higher distribution costs and fewer competing forecourts.
Scotland
Scotland prices track close to the national average, with a notable urban–rural divide.
- Average petrol: 154.6p per litre
- Average diesel: 179.3p per litre
- Cheapest city: Edinburgh — petrol 152.9p, diesel 177.6p
- Most expensive city: Inverness — petrol 156.8p, diesel 181.5p
Edinburgh and Glasgow both benefit from robust supermarket competition, keeping prices competitive. The Highlands, including Inverness, face higher prices due to longer supply routes and thinner forecourt density.
Regional Comparison at a Glance
| Region | Avg Petrol (p/L) | Avg Diesel (p/L) | |---|---|---| | Northern Ireland | 149.7 | 174.3 | | North | 153.1 | 177.5 | | Midlands | 154.4 | 179.1 | | Wales | 154.9 | 179.7 | | Scotland | 154.6 | 179.3 | | South | 157.8 | 182.6 |
The 8.1p petrol spread between Northern Ireland (cheapest) and the South (most expensive) means a driver in London paying the regional average spends roughly £4.46 more per 55-litre fill-up than a driver in Belfast.
Over a year of weekly fill-ups, that regional gap compounds to over £230 — a substantial sum for households watching their budgets.
What's Driving Regional Price Differences
Several structural factors explain why prices vary so significantly across the UK:
- Supermarket competition: Regions with dense supermarket forecourt networks — Northern Ireland, the North, and major Midlands cities — consistently see lower prices. Find cheaper options by comparing brand pages like Tesco.
- Distribution costs: Remote and rural areas (Highlands, mid-Wales, Cumbria) incur longer delivery routes, which translates to higher pump prices.
- Urban operating costs: London and the South East face higher rent, rates, and labour costs, passed through to consumers.
- Forecourt density: Fewer competing stations in a local area reduces downward price pressure.
What This Means for Drivers
While national averages provide a useful benchmark, the July 2026 data shows that your location matters more than ever. Drivers in the most expensive regions can still find cheaper stations by comparing local forecourts — a saving of 5p per litre on petrol equates to £2.75 on a 55-litre fill-up.
