The 25 plate

The age identifier says nothing about where the car came from. That is the memory tag, the two letters in front of it, and all 19 regions were issuing marks in this period.

The 25 identifier was released for 1 March to 31 August 2025. Within that single mark, 1 April was a major vehicle tax boundary. A March registration entered the older first-year schedule and a car registered from April entered the new one. For an electric car, a March date also means exemption from the expensive car supplement, while April onwards means the later price-based test. The digits 25 cannot answer which side the vehicle occupies. Ask for its actual first registration day.

SMMT reported 357,103 new car registrations in March 2025. Battery electric registrations reached 69,313, representing 19.4% of that month's market. Those figures describe the launch surge, including cars registered before April's tax change. They do not imply that every 25 plate EV is taxed alike. A vehicle ordered in March but first registered in April falls under the later rules, whatever deposit date appears on the sales contract.

First-year car rates are charged when the vehicle is initially registered, based on its certified CO2. For a petrol car in the 131 to 150 g/km band, the rate was £270 during March and £540 from April. A zero emission car moved from a £0 first licence to £10. A diesel without RDE2 may have faced the higher first-year band under the published rules. These were one-off first licences, so a used buyer should not treat the historical receipt as their renewal charge.

The current standard annual car rate is £200 from a later licence, including for both March and April 25 plate electric cars. A petrol, diesel or hybrid car whose list price exceeded £40,000 can incur the current £440 expensive car supplement in the second to sixth years after first registration, which for a 25 plate began between March and August 2026. For a zero emission car, the key is its original registration date. One first registered in March 2025 remains exempt from the supplement. A car registered from April 2025 can incur it if the original list price exceeded £50,000 under the threshold applying to licences from April 2026.

The electric £50,000 threshold is retrospective for qualifying zero emission cars first registered from 1 April 2025. A 25 plate EV listed above £40,000 but no more than £50,000 is therefore not charged the supplement on a later licence taking effect from April 2026. HMRC notes one exception: a car whose second licence took effect before 1 April 2026 pays one year of the charge. It is the published list price before discount that counts. Do not rely on an invoice discounted below the threshold, and do not apply this electric threshold to a petrol or hybrid car.

For an ordinary car in Great Britain, the first MOT falls on the third anniversary of its first registration. A genuine 25 plate car first registered from March through August 2025 therefore reaches that date from March through August 2028. The April tax divide does not change the test rule. A March car and an August car have different individual deadlines, even though both display 25. Use the government's MOT status check and the exact registration day to book ahead.

A private car kept under the Northern Ireland scheme normally first tests after four years, putting this cohort in March to August 2029. A Northern Ireland light goods vehicle is due earlier than a private car, so do not take the four-year figure across to a van. Car buyers moving between Great Britain and Northern Ireland should check the current testing record and booking arrangement rather than rely on a seller's informal estimate.

Find the first registration date on the V5C rather than guessing from 25. Then identify the tax class and fuel, inspect the certified CO2 entry for a historical first-year comparison, and ask for the new list price if an expensive car supplement is possible. For a later annual figure, DVLA's vehicle enquiry service shows the car's current tax rates once given the reference number from its V5C. The buyer's own tax starts afresh: the seller's remaining licence does not transfer with the vehicle.

For an April to August zero emission car, the published list price matters even when the asking price has fallen sharply. A £50,000 price does not cross the published 'more than £50,000' threshold; a price above it can. Options fitted when the car was first registered count towards that price in law, so obtain the specification or ask the supplying dealer if the tax record is surprising. For March EVs, the pre-change registration date gives the exemption instead. This is the most useful distinction a 25 plate page can make.

At collection, take the green new keeper slip and tax the car before driving it. If it is being kept off the road, make a SORN instead. Arrange insurance against the registration DVLA currently assigns; a seller keeping a private mark has to take it off, and hold the new log book, before selling. Check the VIN against the document before paying and preserve copies of the advert where a dealer has quoted a particular tax cost.

It should not. DVLA refuses an assignment that would make a vehicle appear newer than its true age. A car first registered before March 2025 cannot legally take a 25 age identifier, even if the owner bought the mark separately. A newer car may carry an older eligible mark, so seeing 25 still does not prove that the underlying vehicle was first registered within this particular window. The V5C gives the date you need.

A seller keeping a personalised 25 mark should transfer or retain it before sale and explain which registration the car will wear when handed over. Ask for the V750 or V778 where the transaction includes an entitlement rather than an already assigned mark. Update insurance and registration-based payment accounts after DVLA processes any change. Fit the physical plates only once the vehicle record shows that the mark is assigned.
