As of March 2026, the United Kingdom is preparing to activate its National Emergency Plan for Fuel (NEP-F) following major disruptions in the Middle East that have led to the closure of the Strait of Hormuz. This critical route accounts for around 20% of the UK’s oil supply, prompting urgent contingency planning.
The Department for Energy Security and Net Zero (DESNZ) has confirmed that fuel supplies remain stable for now. However, the government is actively preparing for potential shortages, including fuel rationing and reduced speed limits across the country.
How Fuel Rationing Could Work
If the supply disruption worsens, the UK may introduce a digital rationing system under the Maximum Purchase Scheme. This would limit how much fuel individuals can buy and prevent panic purchasing.
A Priority User List will be implemented to ensure essential services such as ambulances, fire engines, and logistics providers have uninterrupted fuel access. Selected fuel stations may become Designated Filling Stations, reserved exclusively for these critical users.
50mph Speed Limit Proposal
One of the most significant proposed measures is a temporary nationwide speed limit of 50mph on motorways and major roads. This policy aims to reduce fuel consumption, as vehicles are more efficient at lower speeds due to reduced air resistance.
While this could lead to longer travel times and supply chain delays, the government views it as a necessary step to preserve diesel reserves and maintain essential services.
Fuel Prices and Economic Impact
Fuel prices have already risen sharply, with petrol averaging 141.74p per litre and diesel at 161.20p per litre as of mid-March 2026. Prices are expected to climb further in the short term.

The government has maintained a 5p fuel duty cut and is working with regulators to prevent price gouging. Additionally, a £53 million support package has been introduced to help rural households cope with rising heating oil costs.
Shift Toward Energy Independence
Beyond immediate crisis management, the UK government is accelerating its Clean Power Mission to reduce reliance on fossil fuels. This includes expanding renewable energy projects, supporting plug-in solar for homes, and increasing investment in nuclear and wind power.
Rising fuel costs have also led to a surge in electric vehicle adoption, as consumers seek alternatives to volatile oil markets.
FAQs
Q1 Is petrol rationing currently in effect?
No, petrol rationing has not yet been implemented. It remains a contingency plan under the NEP-F.
Q2 Will the 50mph limit apply to electric vehicles?
Yes, the proposed speed limit would apply to all vehicles to ensure consistency and improve traffic flow.
Q3 What should I do if my local station runs out of fuel?
The government advises against panic buying. Motorists should use official fuel finder tools and refuel responsibly to help stabilize supply.
