Trump's Strait of Hormuz Blockade: What It Means for UK Petrol and Diesel Prices Right Now

As of today, Monday 13 April 2026, President Donald Trump has announced that the United States is imposing a naval blockade on the Strait of Hormuz. In a Truth Social post, he confirmed that the US Navy will begin blockading ships entering or leaving Iranian ports in the strait, starting at 10 a.m. Eastern Time. The move follows the collapse of weekend peace talks in Pakistan and is designed to stop Iran from restricting traffic through this vital waterway.

This is not so good news for anyone who drives in the UK. At GetCheapFuel.co.uk, we track fuel prices from 8,200+ UK petrol stations every single day, and developments like this can push petrol and diesel costs higher very quickly. Let's break down exactly what's happening, why it matters to British drivers, and most importantly – how you can protect your pocket at the pumps.

Why the Strait of Hormuz Matters to UK Fuel Prices

The Strait of Hormuz is one of the world's most important oil chokepoints. Around 20% of global crude oil passes through this narrow stretch of water every day, carrying supplies from major producers including Saudi Arabia, Iraq, the UAE and Kuwait. When shipping is disrupted here – whether by mines, threats or now a formal blockade – the effects ripple straight through to international oil markets.

Brent crude, the benchmark price that UK refineries use, has already climbed sharply on the news. Reports from this morning show oil pushing back above $100 a barrel as traders price in the risk of reduced supply. For UK motorists, that translates directly into higher wholesale costs for petrol and diesel. Even a modest sustained rise in oil can add several pence per litre at the forecourt within days.

We've seen similar spikes before. Supply worries in the Middle East have pushed UK average petrol prices up by 10p to 20p a litre in the past, and those increases tend to stick around until the situation calms. With the blockade now active, analysts are watching closely to see how quickly (or if) shipping companies reroute tankers and how long the disruption lasts.

How This Could Affect Your Fuel Bill in the Coming Weeks

Here in the UK we import most of our refined fuel, so global oil shocks hit us fast. The RAC and AA have already warned that pump prices could rise in the short term as retailers pass on higher wholesale costs. Diesel, which powers many vans, lorries and family cars, is often hit first because of its closer tie to crude prices.

If the blockade drags on or tensions escalate, we could see:

• Petrol prices climbing toward or past 150p per litre in some areas
• Diesel following suit, potentially adding £10–£15 to a typical family car fill-up
• Regional variations, with motorway and rural stations feeling the pressure sooner

The good news is these things rarely happen overnight. You still have time to act smartly and lock in today's better prices before any full impact feeds through.

How GetCheapFuel Helps You Beat Rising Fuel Costs

That's exactly why we built GetCheapFuel.co.uk – to give UK drivers a clear, real-time advantage when prices move. Our interactive map shows the cheapest petrol and diesel near you, updated daily from 8,200+ stations across the country, including supermarkets, independents and major forecourts.

Whether you're searching for cheap fuel in London, Manchester, Birmingham, Edinburghor rural Scotland, our tool pulls the latest prices so you can plan your next fill-up and save straight away. Many drivers save 5p–10p per litre just by checking before they head to the pumps.

Practical Tips to Keep Your Fuel Costs Down During This Uncertainty

While the situation develops, here are straightforward steps every driver can take:

1. 1
   Check prices before every trip – Use our live fuel price map rather than filling up at the first station you see. Enter your postcode or tap "My Location" to see the cheapest options nearby.
2. 2
   Fill up sooner rather than later – If your tank is below half, now is a good time to top up at today's prices before potential increases feed through to forecourts.
3. 3
   Compare supermarkets vs branded stations – Supermarkets like Tesco, Asda, Sainsbury's and Morrisons are typically 3p–5p cheaper per litre than branded forecourts. Our fuel price index shows the brand league table updated daily.
4. 4
   Avoid motorway services – Motorway stations consistently charge 15p–25p more per litre. Plan ahead and fill up before joining the motorway.
5. 5
   Drive efficiently – Keep your tyres properly inflated, remove unnecessary weight, and smooth out your acceleration to stretch every litre further.
6. 6
   Don't panic buy – Stations rarely run dry in these situations. Topping up sensibly is better than queueing and wasting fuel in the process.
