How the September 2025 Number Plate Change Can Affect Your Car’s Value

In the UK, March and September are important months in the motoring calendar — they mark the arrival of new number plates. With the **‘75’ plate due out in September 2025, many car owners are wondering: Should I sell my car before the plate changes? And if so, how much difference does it actually make?

Here’s everything you need to know — including how plate changes affect your car’s resale value, what buyers really look for, and how to time your sale to get the best deal.

📅 What Is the ‘75’ Plate?

The UK registration system adds 20 in March and 70 in September to the current year.

• March 2025: ‘25’ plate was released

• September 2025: ‘75’ plate will be introduced

So if you’re driving a ‘25’ plate now, it’ll no longer be the newest on the road by September. And if you’re still on a ‘73’ or earlier, the perceived age gap widens even more — even if your car is mechanically sound or well-specced.

🧠 Why Plate Changes Matter for Resale Value

While buyers should (in theory) care more about mileage, condition, and service history — in reality, many still make snap judgments based on registration year.

Here’s how the September 2025 ‘75’ plate change can affect your car’s appeal:

✅ Newer Plate = Higher Perceived Value
Even a few months' difference can make your car seem “older” if it carries the previous plate.

✅ Buyers Get More Negotiating Power After a Plate Change
If your car suddenly becomes a ‘last plate’ version, buyers may use it as a reason to negotiate down.

✅ Prestige & Performance Cars Are Hit Harder
Premium buyers often want the latest plates — especially for BMW, Audi, Mercedes, Land Rover, and Porsche models.

✅ Trade-in Offers Drop Quietly After September
Dealers and platforms adjust their algorithms. That great offer you saw in August might be gone by mid-September.

⏱️ Best Time to Sell Before the ‘75’ Plate?

If you’re planning to sell your car — especially a prestige or performance model — the best time is before 1st September 2025. Selling in July or August means:

• You’re selling while your car still has the “newest” plate

• More urgency from buyers who want to avoid new car depreciation

• More accurate offers that reflect your vehicle’s real market value

💰 What Buyers Look for in Late 2025

It’s not just about the number on the plate — savvy buyers will also want:

• ✅ Full service history (especially manufacturer)

• ✅ Desirable extras (pan roof, upgraded sound, driver assist tech)

• ✅ Mileage under segment average

• ✅ Warranty or extended cover

• ✅ Clean ownership history (1 owner preferred)
