Private number plate rules

Under the private number plate rules, a number cannot make your vehicle seem newer than it is. It cannot be fitted to a car with Q registration, and you must display it exactly as issued. If the display is wrong, you could face up to £1,000 in fines and end up with an MOT failure.

How the age rule works

A private number is not allowed if it makes a vehicle look newer than its real age. GOV.UK's example pairs an 07 number with a car first registered in 2003. A dateless number shows no year, so you can use it on a car of any age. A newer car can carry a number that makes it look older. See the UK plate years page to find which identifier fits each date range.

Q registration explained

DVLA issues Q registration numbers if there is doubt about a vehicle's age or identity. You cannot assign or keep a number beginning with Q or QNI, and no private number may go on a Q registered vehicle.

Only UK vehicles

Only UK vehicles may carry a personalised registration number. Such a vehicle must be taxed, be used in the UK, and be registered or be about to be registered.

Private plates: which vehicles are eligible?

The car receiving the number and the car losing it must both follow these rules for private plates. A vehicle must meet all of these conditions:

be DVLA-registered in the UK
be able to travel using its own power
require an MOT certificate or an HGV test certificate because of its type
be available if DVLA asks for an inspection
have had tax or a SORN in place without a break for the past 5 years

Historic (classic) vehicles are normally exempt from the MOT, so check on GOV.UK how that exemption applies to your own vehicle. These conditions are laid out by GOV.UK on the keep or assign a private number page. The application itself is the subject of our assign a private plate guide.

What private plates must look like

Private plate rules for display are identical to those for any plate. Every number plate must:

use a reflective material
use black characters, with a white background in front and a yellow one at the rear
contain no background pattern
carry the supplier's mark and a British Standard number. For fitting from 1 September 2021, the standard is BS AU 145e.

Neither removable nor reflective characters are allowed, and a single shade of black is required on plates fitted after 1 September 2021. A plate can carry 3D (raised) characters, certain flags, identifiers no wider than 50mm, and a green flash for zero emission vehicles.

A rear-only plate appears on motorbikes registered from 1 September 2001 onwards. Its characters sit on 2 lines. Only a registered number plate supplier can make up plates. See GOV.UK's number plate rules for the full details. Check how a reg will look with the Number Plate Maker.

The £1,000 fine, spacing and the MOT

Rearranging letters or numbers is not allowed, nor is altering them so they end up hard to read. DVLA points to fixing bolts as an example of hardware that changes a letter or number. Driving with the wrong display on your plates can bring a fine of up to £1,000, plus an MOT fail.

DVLA may permanently withdraw a number that has been misrepresented in some cases, and you cannot get back what you paid. Even when a number reads as a word only because of odd spacing, you must still display it using standard spacing. Combinations that DVLA considers offensive or inappropriate are also held back: see DVLA banned number plates.

Common questions

What rules apply to private number plates?

A private number cannot make a car look newer or be used on a car with Q registration. You must display it with standard characters and spacing. The vehicle has to be registered in the UK, and taxed or on SORN.

Can you explain the British Standard BS AU 145e?

Plates fitted from 1 September 2021 must carry this British Standard number. Plates fitted before that date display BS AU 145d.

Are 3D number plates allowed?

Yes, that is legal. According to GOV.UK, plates may use 3D (raised) characters if they meet the other rules.

Can any car take a private plate?

No. A number that makes the car look newer than it really is is not allowed, and neither is one on a Q registered car. The car must be a type requiring an MOT, and it must be registered in the UK and used in the UK.
