Will Petrol Cars Become Unaffordable to Own in Britain?

For more than a century, petrol cars have been the backbone of British transport. From the humble runabout to high-performance sports cars, they’ve shaped commuting, culture, and even identity. But in recent years, a question has started to dominate conversations in dealerships, government policy circles, and family driveways alike: are petrol cars heading toward becoming unaffordable to own in Britain?

The answer isn’t a simple yes or no. Instead, it’s a gradual shift driven by taxation, regulation, fuel costs, insurance trends, and the accelerating rise of electric vehicles. What we are likely seeing is not an overnight ban on affordability but a slow financial squeeze that could make petrol cars increasingly expensive to run, insure, and eventually even resell.

The Policy Pressure: Britain’s Road to Net Zero

One of the biggest forces shaping the future of petrol cars is government policy. The UK Government has committed to a legally binding net zero target, and transport is one of the largest contributors to emissions.

The key milestone is the planned phase-out of new petrol and diesel car sales (currently set for 2035, following a delay from 2030). While this does not ban existing petrol cars, it changes the entire market dynamic:

• Fewer new petrol models available over time
• Reduced manufacturer investment in combustion engines
• Shrinking second-hand demand in the long term
• Increasing incentives for electric vehicle adoption

This policy shift doesn’t immediately make petrol cars unaffordable but it sets the stage for long-term depreciation and rising running costs.

Fuel Costs: The Most Visible Squeeze

Ask any driver what hurts most, and it’s almost always fuel prices. Petrol costs in the UK are influenced by global oil markets, but also heavily shaped by taxation, including fuel duty and VAT.

Even small increases in global oil prices can translate into noticeable jumps at the pump. And while electric vehicle charging costs can also rise, they tend to be more stable and predictable.

For a typical petrol hatchback such as a compact model like the Ford Fiesta, fuel costs already account for a major portion of annual ownership expenses. For commuters covering long distances, the difference between petrol and electric running costs can amount to thousands of pounds per year.

If fuel duty is adjusted upward in the future as governments search for new revenue streams while petrol consumption declines the cost gap could widen further.

Clean Air Zones and Urban Restrictions

Another major pressure point is the expansion of Clean Air Zones and Ultra Low Emission Zones (ULEZ), especially in cities like London.

Drivers of older petrol cars may already face daily charges to enter certain urban areas. These schemes are designed to reduce air pollution, but they also effectively penalise older internal combustion vehicles.

In practice, this means:

• Petrol cars lose practicality in major cities
• Daily commuting costs can rise significantly
• Older vehicles depreciate faster in urban markets

For urban residents, especially in and around London, a petrol car is already becoming less economically attractive. Over time, these zones are expected to expand, not shrink.

Insurance and Maintenance: The Hidden Inflation

While fuel and policy get most of the attention, the quieter pressure is coming from insurance and maintenance.

Insurance costs in the UK have risen sharply in recent years due to:

• More expensive vehicle repairs
• Supply chain issues for parts
• Increasing complexity of modern petrol engines
• Higher labour costs in garages

Modern petrol cars are far more technologically advanced than their predecessors. Turbocharged engines, emission control systems, and onboard electronics have made repairs more specialised and expensive.

Even reliable models such as those from major manufacturers like Volkswagen or Ford Motor Company can now carry higher repair bills than older generations of simpler vehicles.

As cars age, these maintenance costs accumulate and they increasingly influence whether keeping a petrol car is economically sensible.

Depreciation: The Silent Wealth Drain

Perhaps the most overlooked factor is resale value. Car ownership is not just about running costs it’s also about how much value you lose over time.

Historically, petrol cars held strong resale value because demand was universal. But this is changing:

• Electric vehicles are becoming more desirable in urban areas
• Fleet buyers are shifting to EVs
• Government policy signals long-term decline of combustion engines
• Environmental concerns influence buyer preferences

This creates a potential “value cliff” effect. As confidence in long-term petrol demand declines, resale prices could fall faster than expected.

Electric models like the Tesla Model 3 and the Nissan Leaf are already reshaping expectations of what “normal” running costs look like. As more drivers switch, petrol vehicles risk becoming less desirable in the second-hand market.

The EV Price Paradox: Expensive Up Front, Cheaper Over Time

One reason petrol cars haven’t collapsed in value yet is simple: electric vehicles still often cost more upfront.

However, ownership economics are shifting:

• EVs have lower “fuel” costs (electricity vs petrol)
• EV maintenance is typically cheaper (fewer moving parts)
• Road tax incentives still favour low-emission vehicles
• Some workplace and home charging schemes reduce costs further

This creates a paradox: petrol cars feel cheaper at purchase, but may become more expensive to own long-term.

As battery prices fall and EV production scales up, the upfront price gap is expected to shrink. When that happens, petrol cars could become harder to justify financially for everyday drivers.

The Rural vs Urban Divide

It’s important not to assume a uniform experience across Britain. The affordability question looks very different depending on where you live.

In cities:

• Charging infrastructure is improving
• Clean Air Zones are expanding
• Petrol restrictions are more common
• EVs make strong financial sense

In rural areas:

• Charging access can still be limited
• Longer journeys favour flexible refuelling
• Petrol vehicles remain practical and sometimes essential

This means petrol cars are unlikely to disappear entirely but they may become increasingly concentrated in rural and specialist use cases rather than everyday urban transport.

Will Petrol Cars Become “Unaffordable”?

The key distinction is between absolute affordability and relative affordability.

Petrol cars are unlikely to become literally unaffordable in the sense of being financially impossible to own. Instead, the more realistic scenario is:

• They become more expensive to run compared to EVs
• They lose resale value faster
• They face increasing city restrictions
• Insurance and maintenance costs continue rising
• Incentives shift away from them

In other words, petrol cars may not become unaffordable but they may become financially irrational for many drivers.

What This Means for Drivers Today

For current owners, the situation is not urgent panic but it is a signal to think strategically:

• If you already own a petrol car, it is not suddenly obsolete
• Well-maintained vehicles will still function for many years
• However, long-term value retention may decline
• Switching decisions will increasingly depend on usage patterns

For buyers, the decision is becoming more complex. A petrol car might still make sense for certain lifestyles, but the economic balance is shifting faster than many people realise.

The Likely Future: A Gradual Transition, Not a Sudden Collapse

Despite dramatic headlines, Britain is not about to banish petrol cars overnight. What is happening instead is a structured transition:

• Petrol cars remain legal and usable for years
• New sales gradually phase down
• Costs slowly tilt toward electric alternatives
• Market demand shifts over time

This means petrol cars will likely coexist with electric vehicles for decades but in a progressively smaller and more specialised role.

Final Thought

So, will petrol cars become unaffordable in Britain?

Not in the strict sense. But they are very likely to become increasingly expensive relative to electric alternatives, especially in cities and for high-mileage drivers.

The real shift is not just about price it’s about practicality, policy, and perception. And once those three align, affordability becomes less about what you can afford, and more about what still makes financial sense to own.

The petrol era isn’t ending abruptly but it is steadily becoming more expensive to stay in.
