Britain’s road tax system is quietly running out of road.
Fuel duty — the tax baked into every litre of petrol and diesel — has been the backbone of UK road funding for decades. But as electric vehicles accelerate and fuel consumption drops, that system is losing billions each year. The Treasury knows it. Policymakers know it. And increasingly, drivers are starting to hear about the proposed replacement: pay per mile tax.
The phrase sounds simple. Almost fair. But the details matter — a lot.
This in-depth guide explains what pay per mile tax really is, how it would work in practice, whether it’s actually coming to the UK, how much it could cost different drivers, and why it’s far more complex than “a few pennies per mile.”
Everything here reflects credible UK policy discussions as of 2026, not speculation or clickbait.
What Is Pay Per Mile Tax?
A pay per mile tax (also called road pricing or mileage-based charging) is a system where drivers are charged based on how far they drive, rather than:
- How much fuel do they buy
- Or a flat annual vehicle tax
Under such a system:
- Driving more = paying more
- Driving less = paying less
The core idea is not new. What is new is the urgency.
Fuel duty currently raises over £24.7 billion per year for the UK government. Electric vehicles contribute almost nothing to that pot. As EV adoption increases, fuel duty revenue declines — even if total road usage stays the same.
Pay per mile tax is designed to replace fuel duty, not punish drivers or raise revenue arbitrarily.
Why the UK Is Even Considering Pay Per Mile Tax
The motivation isn’t environmental virtue-signalling. It’s math.
The Structural Problem
- Fuel duty depends on fuel consumption
- EVs don’t use fuel
- More EVs = less tax revenue
At the same time:
- Road maintenance costs remain
- Traffic congestion increases
- Infrastructure spending rises
This creates a widening funding gap that cannot be closed by simply raising existing taxes without political fallout.
Pay per mile tax is appealing because it:
- Applies equally to petrol, diesel, and electric cars
- Scales with actual road usage
- Creates a stable long-term revenue base
Is Pay Per Mile Tax Coming to the UK?
Not imminently — but it is very likely long-term.
As of 2026:
- No legislation has been passed
- No start date has been announced
- No final system has been approved
However:
- Treasury reports openly acknowledge fuel duty’s decline
- Parliamentary committees have reviewed mileage-based taxation
- Think tanks and transport bodies increasingly describe it as “inevitable.”
Most credible estimates place serious implementation in the late 2020s or early 2030s, with pilots and consultations well before that.
This is not a “next Budget” change. It’s a structural transition.
How Does Pay Per Mile Tax Work? (In Practice, Not Theory)
This is where confusion usually starts.
Step 1: Mileage Measurement
Mileage could be recorded using one or more of the following:
- Annual MOT odometer readings
- Periodic self-reported mileage (with penalties for false reporting)
- In-vehicle telematics (likely optional or regulated)
The UK already records mileage annually for most vehicles. No new technology is strictly required.
Step 2: Rate Calculation
Drivers would be charged a per-mile rate, potentially adjusted by:
- Vehicle type
- Emissions category
- Weight or road wear impact
Early modelling suggests figures between 2p and 6p per mile, though these are not official rates.
Step 3: Billing
Instead of paying fuel duty at the pump, drivers would likely:
- Receive a periodic bill (monthly, quarterly, or annually)
- Pay digitally, similar to utilities or VED
How Much Would Pay Per Mile Tax Cost?
There is no single answer — and that’s the point.
Example Scenarios (Illustrative Only)
| Driver Profile | Annual Miles | 3p per Mile | Likely Outcome |
|---|---|---|---|
| City commuter | 5,000 | £150 | Often cheaper than today |
| Average UK driver | 8,000 | £240 | Roughly neutral |
| Rural resident | 14,000 | £420 | Often higher |
| High-mileage worker | 20,000 | £600 | Higher unless exempted |
Key insight: Pay per mile tax rewards low usage, not vehicle choice.
How Does This Compare to the Current Car Tax?
Pay Per Mile vs VED + Fuel Duty
| Factor | Current System | Pay Per Mile |
|---|---|---|
| Based on | Fuel + emissions | Distance |
| Fair to EVs | ❌ | ✅ |
| Encourages less driving | ❌ | ✅ |
| Simple to understand | ✅ | ⚠️ |
| Rural impact | Neutral | Potentially higher |
Many landlords and property owners drive regularly for property inspections, viewings, or managing multiple rentals. While taxes on property income are a major consideration, vehicle-related taxes also affect overall expenses. For instance, just as pay-per-mile taxes can be controversial because they redistribute who pays, vehicle tax planning is essential.

Who Benefits — and Who Loses?
Likely Winners
- Urban drivers
- People who work from home
- Households with multiple low-use cars
- Occasional drivers
Likely Losers
- Rural households
- Tradespeople
- Delivery and taxi drivers
- Long-distance commuters
This is why most serious proposals include:
- Lower rural rates
- Occupational exemptions
- Annual mileage allowances
Without these, the system would struggle politically.
How Will Mileage Be Tracked? (Privacy, Explained Calmly)
This is the biggest fear — and the most exaggerated.
Despite headlines, no credible UK proposal requires constant GPS tracking.
Most discussions focus on:
- Odometer-based reporting
- Minimal data collection
- No journey-level tracking
Any system that involved live tracking of movements would:
- Face legal challenges
- Breach data protection norms
- Likely fail politically
In short, distance matters; location probably won’t.
What About Electric Vehicles?
EVs are central to this debate.
Right now:
- EV drivers pay little or no fuel duty
- Many also pay reduced or zero VED
This advantage was intentional — to encourage adoption.
But once EVs become mainstream, maintaining that exemption becomes financially unsustainable. Pay per mile tax would:
- Bring EVs into road funding
- Remove the “free road use” perception
- Still reward efficient, low-usage driving
For most EV owners, mileage will matter more than powertrain.
Common Myths About Pay Per Mile Tax
“It’s Just Another Tax”
No. The intent is to replace fuel duty, not stack taxes.
“Everyone Will Pay More”
Some will. Many won’t. Low-mileage drivers often pay less.
“They’ll Track Everywhere You Go”
There is no requirement — or appetite — for full journey tracking.
“It’s Happening Next Year”
It isn’t. This is a long-term transition.
What Would a Fair Pay Per Mile System Need?
Any workable system would need:
- Clear rural protections
- Occupational allowances
- Transparent pricing
- Strong privacy safeguards
- Gradual rollout
Without these, public resistance would be intense.

What Happens Next? (2026–2028 Outlook)
Expect:
- Policy papers, not laws
- Pilot schemes
- EV-specific trials
- Public consultations
This will be debated for years before implementation.
FAQs
Q. Is pay per mile tax coming to the UK?
Pay per mile tax is not currently in force in the UK. As of 2026, it remains a proposal under government and parliamentary review, with no confirmed start date. The idea is being explored as a long-term replacement for fuel duty as electric vehicle use increases, but any rollout would likely happen in the late 2020s at the earliest.
Q. How would pay per mile tax work in the UK?
Pay per mile tax would charge drivers based on the number of miles they drive each year. Instead of paying tax through fuel purchases, drivers would be billed according to recorded mileage, potentially collected through MOT odometer readings or periodic reporting. The goal is to link road tax more closely to actual road usage.
Q. How much would pay per mile tax cost per mile?
Early estimates suggest a rate of around 2p to 6p per mile. These figures are based on Treasury modelling and think-tank analysis, not confirmed policy. The final cost per mile could vary depending on vehicle type, emissions, or usage, and no official rate has been set.
Q. Will pay per mile tax replace fuel duty?
Yes, replacing fuel duty is the most likely long-term purpose of pay per mile tax. Fuel duty revenues are falling as electric vehicles replace petrol and diesel cars. A mileage-based system is widely viewed as the most practical alternative to fund road maintenance once fuel duty becomes unsustainable.
Q. How will mileage be tracked for pay per mile tax?
Most proposals favour simple mileage reporting rather than GPS tracking. Likely methods include annual MOT odometer readings or scheduled mileage declarations. Current discussions do not require real-time location tracking, and privacy safeguards are expected to be a core part of any system.
Q. Is pay per mile tax bad for rural drivers?
Pay per mile tax could affect rural drivers more unless protections are introduced. People in rural areas often drive longer distances due to limited public transport. For this reason, many proposals include lower rural rates, mileage allowances, or exemptions to reduce unfair impacts.
Conclusion: Should Drivers Be Worried?
Pay per mile tax isn’t about punishing motorists. It’s about replacing a funding model that no longer matches how Britain drives.
For some drivers, it could mean higher costs. For others, it may actually reduce what they pay. The real risk isn’t the concept — it’s poor design.
Understanding how it works now puts you ahead of the headlines when the debate inevitably heats up.
