How Far Can You Drive on £30 of Fuel?
The UK government is reviewing emergency fuel rationing plans that could limit purchases to £30 per visit under the Energy Act 1976. At today's prices, that buys you 19.0 litres of unleaded — enough for roughly 167 miles. But it depends where you fill up.

The Price Gap Changes Everything
Not all stations charge the same. The difference between the cheapest and most expensive station in the UK means your £30 could take you twice as far — or half as far — depending on where you fill up.
At the cheapest station (114.1p)
231 miles
26.3 litres for £30
At the most expensive (239.9p)
110 miles
12.5 litres for £30
That's a 121-mile difference on the same £30 budget. Choosing the right station matters more than ever if rationing comes in.

What Is the UK Fuel Rationing Plan?
Under the Energy Act 1976, the UK government has emergency powers to control fuel distribution during a supply crisis. The National Emergency Plan for Fuel (NEP-F) outlines several escalation stages, from voluntary conservation measures to full rationing.
One key tool is the Maximum Purchase Scheme, which would cap how much fuel a driver can buy per visit. Media reports have cited a limit of around £30 per transaction. Priority access would go to emergency services, NHS staff, utility companies, and public transport.
The plans are being reviewed following Middle East tensions and disruption to oil shipping routes. As of 5 June 2026, no rationing is currently in effect, but the government has confirmed it is updating its contingency plans.
How to Get the Most Out of £30 of Fuel
Compare before you fill up
Use the postcode checker above to find the cheapest station nearby. The price gap between stations in the same area can mean 30-50 extra miles on the same £30.
Avoid motorway services
Motorway fuel stations typically charge 10-20p more per litre than supermarket forecourts. On a £30 budget, that's 1-2 fewer litres and 10+ fewer miles.
Fill up at supermarkets
Tesco, Sainsbury's, Asda, and Morrisons consistently rank among the cheapest fuel retailers. Supermarket loyalty cards and fuel vouchers can cut costs further.
Drive efficiently
Gentle acceleration, maintaining tyre pressure, and removing roof boxes can improve fuel economy by 10-20%. At 45mpg instead of 40mpg, £30 of fuel takes you an extra 15-20 miles.
£30 of Petrol vs £30 of Diesel
Diesel is more expensive per litre than petrol, so £30 buys fewer litres. However, diesel engines are typically more fuel-efficient. Here's how the two compare at today's average prices:
| Fuel type | Avg price | Litres for £30 | Range (40mpg) | Range (50mpg diesel) |
|---|---|---|---|---|
| Unleaded (E10) | 158.3p | 19.0L | 167 mi | — |
| Diesel (B7) | 181.4p | 16.5L | 145 mi | 182 mi |
At 50mpg (common for modern diesel cars), a diesel driver gets roughly 182 miles from £30 — more than a petrol driver at 40mpg despite paying more per litre.
Frequently Asked Questions
How many litres does £30 buy?
At today's average unleaded price of 158.3p, £30 buys 19.0 litres. For diesel at 181.4p, it buys 16.5 litres. At the cheapest UK station (114.1p), you'd get 26.3 litres.
How far can I drive on £30 of petrol?
In a typical petrol car averaging 40mpg, £30 of unleaded at the national average price gets you roughly 167 miles. At the cheapest station, you could get up to 231 miles. At the most expensive, as little as 110 miles.
Will fuel rationing actually happen in the UK?
As of 5 June 2026, no fuel rationing is in effect. The government is reviewing contingency plans under the Energy Act 1976 as a precautionary measure. Rationing would only be activated in the event of a severe supply disruption. Fuel is currently available normally at all UK stations.
Who gets priority in UK fuel rationing?
Under the National Emergency Plan for Fuel, priority goes to emergency services (police, fire, ambulance), the NHS, utility companies, public transport, and then commercial vehicles. Private motorists would face the strictest limits, including the potential £30-per-visit cap.
Why do fuel prices vary so much between stations?
Fuel prices depend on wholesale costs, competition, location, and retailer margins. Supermarket forecourts (Tesco, Asda, Sainsbury's, Morrisons) tend to be cheapest due to thin margins, while motorway services and remote rural stations charge more. The gap between the cheapest and most expensive station in the UK is currently 125.8p per litre.
