EV road tax powers explained
Electric car owners could face more than an additional tax bill under the Government's planned pay-per-mile scheme. Draft legislation also proposes giving authorised police officers and vehicle examiners powers to enter premises where a vehicle is kept if they suspect certain mileage-related offences.
The proposed powers would allow them to inspect and test a vehicle, detain it for the time needed to carry out checks and, where necessary, drive it to a suitable inspection location. Drivers could also be required to move their vehicle or remain with it during an inspection.
The plans have prompted criticism from politicians and civil liberties campaigners, who argue that innocent motorists could face intrusive checks following a simple mileage reporting error.
However, there's an important distinction between the powers being proposed and claims that police will routinely raid people's homes. The draft legislation sets out powers linked to suspected offences. It does not mean every driver who submits an incorrect reading will automatically face a visit.
The Government has said the powers would rarely be used, with routine mileage checks intended to help identify discrepancies before further enforcement becomes necessary.
When does electric car pay-per-mile tax start?
Electric Vehicle Excise Duty, known as eVED, is scheduled to come into force on 1 April 2028. It will apply to battery electric cars, plug-in hybrid cars and hydrogen-powered cars that fall within the scheme.
Under the announced rates, fully electric and hydrogen-powered cars will incur a charge of 3p per mile, while plug-in hybrids will pay 1.5p per mile. The charge will sit alongside Vehicle Excise Duty (VED), the standard road tax motorists already pay.
The Government says the new levy is intended to address the long-term decline in Fuel Duty receipts as more drivers switch away from petrol and diesel vehicles.
For drivers, the extra cost will depend on annual mileage. Covering 10,000 miles in a fully electric car would generate £300 in eVED at the initial rate. The same distance in a plug-in hybrid would cost £150.
These figures assume the announced rates remain unchanged and exclude VED and other running costs. The Government plans to adjust the rates in line with inflation in future years.
The scheme will be administered by the Driver and Vehicle Licensing Agency (DVLA). Drivers will provide an odometer reading and estimate their mileage for the coming tax period, with payments reconciled against actual mileage later.
How will police check electric car mileage?
The proposed enforcement system relies on recorded mileage, with annual MOT readings providing an important cross-check for most cars.
Drivers will be expected to provide mileage information when renewing their vehicle tax. Authorities can compare the figures with available MOT records to help identify possible attempts to under-report mileage.
A discrepancy could have several explanations. Deliberate tampering is one possibility, but a reporting mistake or an incorrect MOT entry could also create a mismatch that needs investigating.
Under the draft provisions, an authorised constable or vehicle examiner who suspects a relevant offence could exercise inspection powers at premises where they have reason to believe the vehicle is kept. Those powers include testing the car and detaining or moving it for inspection.
The proposed legislation also provides for offences connected with odometer tampering and certain mileage-record requirements. The precise circumstances in which the powers may be exercised, including any conditions set through regulations, matter here. A mileage discrepancy alone should not be treated as proof of fraud.
For cars that are less than three years old and have not yet had their first MOT, mileage verification will need to follow a different process because there is no routine MOT reading to compare against.
Could innocent drivers face a police visit?
This is the part of the proposals most likely to concern ordinary motorists.
Mileage figures are usually straightforward, but errors can happen when information is entered or recorded. A driver could therefore be worried about being investigated after an innocent mistake, particularly if the system initially flags a discrepancy as suspicious.
The Government's stated position is that enforcement powers will rarely be needed because routine checks should identify mileage issues. That is a useful safeguard in principle, although the practical details of how suspected errors will be handled will be important.
Civil liberties campaigners have criticised the prospect of officials entering premises and inspecting private vehicles. Conservative transport spokesperson Greg Smith has also attacked the proposed powers, arguing that they give the authorities excessive reach over motorists.
Howard Cox, founder of FairFuelUK, has similarly condemned the prospect of police involvement in mileage enforcement. These are political and campaign-group objections, not evidence that routine home visits are planned for every driver.
The central issue is how the system distinguishes deliberate fraud from an honest mistake. Clear guidance, a fair opportunity to correct errors and proportionate enforcement would help prevent an administrative problem from escalating unnecessarily.
Will electric car drivers pay tax on miles abroad?
Yes. Under the Government's announced plans, eVED will apply to mileage covered by UK-registered cars, including journeys made overseas.
That means a driver taking an electric car on holiday in Europe could still incur the mileage charge while driving abroad.
Ministers have argued that excluding overseas journeys would require a way to establish where a vehicle had been driven. The Government has said it does not intend to collect journey location or timing data or require tracking devices for the scheme.
This creates a clear trade-off. Charging for all mileage avoids the need for journey-by-journey location monitoring, but it also means motorists could pay the levy on miles driven outside the UK.
For drivers who regularly take their cars abroad, that is another detail worth factoring into the cost of ownership.
What the new EV tax means for motorists
The Government has a clear reason for introducing eVED. As more drivers move to electric cars, the Treasury receives less Fuel Duty from petrol and diesel sales. A mileage-based charge is intended to help address that gap.
However, the new levy will add to the cost of running an electric car, and the proposed enforcement powers raise legitimate questions about privacy, mistakes and proportionality.
The best approach would be to make the reporting process simple, give drivers a straightforward way to correct inaccurate readings and ensure intrusive inspections are reserved for cases where there is a proper basis for suspicion.
The scheme is still being developed through legislation and associated regulations, so the final enforcement arrangements deserve close scrutiny.
Our verdict on the new EV road tax
A mileage-based charge may be a reasonable way to address the tax revenue lost as drivers switch to electric cars, but the Government needs to get the enforcement right. Drivers should not have to worry that an innocent error will automatically lead to an intrusive inspection.
The proposed powers are significant, and the public deserves a clear explanation of the safeguards that will govern their use. Until those details are settled, the strongest criticism is not that every EV owner will face a home raid, but that the Government must demonstrate how it will prevent legitimate mileage checks from becoming disproportionate enforcement.
For anyone considering an electric car, eVED is another future running cost to include in the budget. April 2028 is the planned start date, so there is time for the rules to be scrutinised before drivers begin paying.
