Used EV prices have come down a lot, which is brilliant. But one running cost that now catches people out is UK road tax (Vehicle Excise Duty, or VED). Since April 2025, electric cars are no longer automatically "£0 tax", and the rules depend on when the car was first registered and, for some cars, its original list price.
If you are buying a used EV in 2026, this checklist will help you avoid the classic surprise, "why is my EV tax suddenly £640 a year?"
1) Check the first registration date (this is the big one)
For EV VED, the first registration date determines which rate bucket the car sits in. GOV.UK's guidance lays out the rates for 1 April 2026 to 31 March 2027:
- Registered on or after 1 April 2025: £10 in the first year, then the standard rate (£200) from year two onwards.
- Registered between 1 April 2017 and 31 March 2025: standard rate (£200).
- Registered between 1 March 2001 and 31 March 2017: £20 (under the older banding).
Used-car takeaway: most used EVs you see on the market will land on £200/year, but older EVs can be £20/year, and very new ones can be in the "first year vs year two" situation.
2) Check whether it crosses the "Expensive Car Supplement" threshold
VED has an extra charge often called the "luxury car tax", officially the Expensive Car Supplement. For electric or zero-emission cars registered on or after 1 April 2025, GOV.UK notes it applies if the vehicle's list price is more than £50,000.
Three details matter when you are buying used:
- It is based on list price, not what you paid. Discounts on the used market do not change the original list price.
- Options count. A car that was "from £49,999" can cross the line with factory options.
- It follows the vehicle. If the supplement applies, it is still due even when the car changes hands (and it applies for a fixed number of years, starting from year two of the car's life).
Used-car takeaway: a "bargain" used EV can still have a premium VED bill for a few years if it was originally specced over the threshold.
3) Turn VED into a cost-per-mile number (it makes budgeting easier)
VED is not mileage-based, but you can make it feel much less fuzzy by converting it into a per-mile cost using your own driving habits.
Example:
- If VED is £200/year and you drive 8,000 miles/year, that is 2.5p per mile.
- If you drive 12,000 miles/year, it is 1.7p per mile.
This is exactly where mileage logging helps, because you do not have to guess your annual mileage. You can base it on your actual rolling 3 to 12 month pattern.
4) If you claim mileage for work, keep the record clean
Plenty of EV drivers buy used cars for a mix of personal and work journeys. Even though VED is an annual cost, good mileage records make it easier to:
- separate work vs personal journeys,
- understand your real running cost per mile,
- spot shifts in driving behaviour (new commute, more client visits, longer trips).
Whether you are doing expense claims, self-employed records, or simply trying to keep a lid on running costs, the habit of logging trips pays for itself.
5) Quick "before you buy" checklist
- ✅ Confirm the first registration date (this drives the base VED band).
- ✅ Ask (or research) the car's original list price and whether options likely push it over £50,000.
- ✅ If it is a newer car, sanity-check whether you are in year one vs year two VED.
- ✅ Add VED to your monthly budget, or convert it to pence per mile using your actual mileage.
- ✅ Start logging mileage from day one so your running-cost picture stays accurate.
