What Rachel Reeves proposed for electric vehicles

In autumn 2024, UK Chancellor Rachel Reeves announced plans to introduce a per-mile tax on electric vehicles, beginning in 2025. The proposal would charge drivers based on the distance they travel rather than a flat annual fee, similar to how petrol and diesel vehicles are taxed through fuel duty. The exact rate per mile has not been set, and the plan still requires parliamentary approval before it becomes law.

This marks a significant shift in how the UK taxes vehicle use. Currently, electric vehicle owners pay vehicle tax (road tax) like all drivers, but they pay a lower rate or nothing at all depending on when they bought the car — a policy designed to encourage the switch away from fossil fuels. Reeves' proposal would eventually bring electric vehicles into a system that taxes actual road use rather than vehicle ownership alone.

Key Takeaways

  • Rachel Reeves proposed a per-mile tax on electric vehicles starting in 2025, charged based on distance travelled rather than as a flat annual fee.
  • The exact rate per mile has not been announced, and the plan requires parliamentary approval before it can take effect.
  • Current electric vehicle owners may face different tax rates depending on when they purchased their car and how the transition rules are written.
  • The proposal aims to replace or supplement existing vehicle tax as more drivers switch to electric cars and fuel duty revenue falls.
  • How the tax is collected — through odometer readings, insurance data, or another method — remains unclear and will affect how drivers experience the change.

Why the government is considering this change

The UK government collects significant revenue from fuel duty — a tax added to every litre of petrol and diesel sold. As more drivers switch to electric vehicles, which use no petrol or diesel, that revenue stream shrinks. The Office for Budget Responsibility has warned that fuel duty income will fall sharply over the next decade as electric vehicle ownership rises.

A per-mile tax is one way to replace that lost revenue while keeping the principle that drivers who use the roads more should pay more. It also avoids a situation where electric vehicle owners pay nothing toward road maintenance and upkeep, while petrol and diesel drivers continue to pay through fuel duty.

Reeves framed the proposal as a fairness issue: as the vehicle fleet becomes cleaner, the tax system needs to adapt so that all drivers contribute to the cost of roads, regardless of what powers their car.

How a per-mile tax would work in practice

The mechanics of collecting a per-mile tax are not yet finalised, but several methods are possible. One approach would use odometer readings — the distance counter on your dashboard — checked at MOT tests or insurance renewals. Another could use GPS or telematics data, where a device in the car records mileage automatically. A third option would tie the tax to insurance companies, which already know how far many drivers travel.

The rate per mile has not been announced. To understand the scale, consider that fuel duty currently raises roughly £28 billion per year in the UK. If that revenue were spread across all miles driven by all vehicles, the per-mile rate would need to be substantial — but the actual rate will depend on how many electric vehicles are on the road when the tax starts, and whether it applies to all vehicles or only electric ones.

The government has not said whether the tax would replace vehicle tax entirely, sit alongside it, or replace fuel duty for electric vehicles while petrol and diesel drivers continue paying fuel duty. These details will shape how much drivers actually pay and when.

Who would be affected and when

The proposal would affect anyone who owns or drives an electric vehicle in the UK once the tax takes effect. Reeves mentioned 2025 as the starting point, though that timeline could shift depending on parliamentary debate and the practical work needed to set up the collection system.

Current electric vehicle owners may face a transition period. Some bought their cars specifically because they offered tax advantages; the government may phase in the new tax gradually, explore it only to new purchases, or grandfather in existing owners for a set period. None of these details have been confirmed.

Drivers of petrol and diesel vehicles would not be directly affected by this tax, though they would continue paying fuel duty as usual. However, if the per-mile tax eventually expands to all vehicles — which some policy experts have suggested as a longer-term possibility — that would change.

What this means for electric vehicle costs

For many electric vehicle owners, the per-mile tax would represent a new cost that did not exist before, or would replace the current vehicle tax advantage. The actual impact on your wallet depends on how far you drive each year and what the per-mile rate turns out to be.

A driver who covers 10,000 miles per year — roughly the UK average — would pay a different amount than someone who drives 20,000 miles annually. The per-mile model means high-mileage drivers pay more, which mirrors how fuel duty works: drivers who use more fuel pay more tax.

For some owners, the new tax might make electric vehicle ownership less attractive financially compared to petrol or diesel cars, depending on the rate and how it compares to current fuel costs. For others, especially those who drive less, it could be cheaper than paying fuel duty on a conventional car.

What remains uncertain about the plan

Several key details have not been settled. The government has not announced the per-mile rate, the exact start date, how the tax would be collected, or whether it would explore only to new electric vehicles or to all of them. It has also not confirmed whether vehicle tax would be abolished for electric vehicles or whether drivers would pay both.

Parliament must debate and vote on the proposal before it becomes law. That process could result in changes to the plan, delays to the timeline, or even rejection. Public and industry response may also influence how the government refines the proposal before it is finalised.

The logistics of collection are also unresolved. If the tax relies on odometer readings at MOT or insurance renewal, the system already exists but would need to be adapted. If it uses GPS or telematics, new infrastructure would be required, and privacy questions would arise about how that data is stored and used.

How this compares to other countries

Several countries have experimented with or implemented per-mile or distance-based vehicle taxes. Norway, which has the highest electric vehicle ownership rate in the world, has discussed similar ideas as its fuel tax revenue declines. Some US states have piloted per-mile systems, and the European Union has explored distance-based road pricing.

Most of these systems are still in early stages or explore only to certain vehicle types or regions. The UK would not be the first to attempt this, but the scale and timing of Reeves' proposal — explore it as electric vehicles become mainstream — is relatively ambitious.

Frequently Asked Questions

When will the per-mile tax start?

Rachel Reeves mentioned 2025 as the target year, but that timeline has not been confirmed by parliament or the Department for Transport. The exact start date will depend on how quickly the government can set up the collection system and pass the necessary legislation.

Will current electric vehicle owners have to pay the tax?

That has not been decided. The government may phase in the tax gradually, explore it only to new purchases, or grandfather in existing owners for a period. These transition rules will be crucial for owners who bought electric vehicles partly because of tax benefits.

How much will the per-mile tax cost?

The rate per mile has not been announced. The cost will depend on how far you drive each year and what rate parliament approves. The government will likely publish estimates before the tax takes effect.

Will petrol and diesel cars also pay a per-mile tax?

The current proposal focuses on electric vehicles. Petrol and diesel drivers would continue paying fuel duty. However, some policy experts have suggested that a per-mile system could eventually expand to all vehicles as a longer-term replacement for fuel duty.

How would the government collect a per-mile tax?

The collection method has not been finalised. Possible approaches include odometer readings at MOT or insurance renewal, GPS or telematics devices in the car, or data from insurance companies. Each method has different privacy and practical implications.
