The global situation in Iran might feel far removed from the UK car market—but in reality, it’s already having a noticeable impact on used car prices across the country.
From rising fuel costs to shifting buyer behaviour, the knock-on effects are changing what cars people want—and how much they’re willing to pay.
Here’s what’s happening, and what it means if you’re buying or selling a used car in 2026.
Rising fuel prices are reshaping demand
The biggest and most immediate impact of the Iran crisis has been on oil prices.
With disruption in the Strait of Hormuz and reduced global supply, oil prices have surged—pushing UK petrol and diesel costs sharply higher.
That matters because fuel prices directly influence car buying decisions.
When fuel becomes more expensive:
- Demand for SUVs and large petrol/diesel cars drops
- Demand for small, efficient cars rises
- Hybrid and electric vehicles become more attractive
This shift is already visible in the used market, where buyers are actively seeking cheaper-to-run vehicles.
Outcome:
Prices are rising for fuel-efficient cars—but softening for less economical models.
The used car market is splitting in two (or three)
Industry data suggests the Iran crisis hasn’t pushed all prices up equally—it’s actually fragmenting the market.
According to recent analysis, the UK used car market is now dividing into:
- High-demand, low-running-cost vehicles (prices rising)
- Traditional petrol/diesel cars (prices stabilising or falling)
- EVs and hybrids (increasing demand and price resilience)
At the same time, used EV sales have surged following the crisis, reflecting changing consumer priorities.
Outcome:
There’s no single “used car price trend” anymore—your car’s value depends heavily on fuel type and efficiency.
Top tips for buying a new car
If you’re in the market for a new car in the current climate, it pays to be strategic. Start by prioritising running costs over just purchase price—with fuel prices volatile, a more efficient petrol, hybrid or electric vehicle could save you significantly in the long run.
Be flexible on things like brand, colour or spec to widen your options, and compare similar models to spot better value. It’s also worth acting decisively when you find a good deal, as high-demand cars are selling quickly.
Finally, always carry out a Total Car Check before buying to avoid hidden issues and give yourself confidence that you’re getting what you paid for.
Inflation and economic uncertainty are pushing prices up
The Iran crisis isn’t just affecting fuel—it’s feeding into broader UK inflation.
- UK inflation has risen to around 3.3%, driven largely by fuel costs
- Over 25% of UK businesses expect to raise prices in the near term
- Consumer confidence has dropped significantly amid economic uncertainty
For the used car market, that creates a complex dynamic:
- Sellers may raise prices to keep up with inflation
- Buyers may delay purchases or lower budgets
Outcome:
Upward pressure on prices—but weaker demand in some segments.
Supply constraints are still keeping prices elevated
Even before the Iran crisis, used car prices were already high due to limited supply.
That hasn’t changed.
The UK market is still dealing with:
- Fewer new cars sold during previous years
- Reduced availability of quality used stock
- Strong competition among buyers
As a result, used car values remain elevated in 2026 despite economic headwinds.
Outcome:
Prices aren’t falling significantly—just shifting depending on vehicle type.
EVs are gaining momentum faster than expected
One of the biggest long-term effects of the Iran crisis could be the acceleration of EV adoption.
With fuel prices rising:
- Electric cars are becoming more cost-competitive
- Some reports now show EVs cheaper than petrol cars on average in the UK
This is already feeding into the used market:
- Higher demand for second-hand EVs
- Stronger residual values
- Faster turnover for electric stock
Outcome:
Used EV prices are holding firm—and may rise further if fuel costs stay high.
What this means for buyers and sellers
If you’re buying:
- Expect higher prices for economical cars and hybrids
- You may find better deals on larger petrol or diesel vehicles
- EVs could offer better long-term value despite higher upfront cost
If you’re selling:
- Fuel-efficient cars are currently in high demand
- Timing matters—market conditions are volatile
- A vehicle history check can help justify your asking price and build buyer trust
Final thoughts
The Iran crisis hasn’t simply pushed UK used car prices up—it’s changed the structure of the market.
- Fuel costs are driving buyer decisions
- Inflation is adding pressure across the board
- EV adoption is accelerating faster than expected
In short, the market is no longer moving as one.
Outcome:
In 2026, as you would expect, what your car is worth depends less on age and mileage—and more on how much it costs to run.
