Whether you have cracked a plate reversing into a bollard, failed your MOT over a faded registration, or you are a dealer prepping a vehicle for the forecourt, you need standard number plates that are road legal, built to the correct British Standard, and will not cost a fortune.
At CarPlatesPro, we supply fully DVLA-compliant standard number plates across the UK from just £9.99, the lowest price of any registered supplier in the country. This guide tells you everything you need to know: what is legal, what is not, what sizes you need, and how to order in under two minutes.
Standard number plates are the legally required identification plates displayed on the front and rear of every motor vehicle on UK roads. They show your unique DVLA-assigned vehicle registration in a format tightly controlled by law, including the font used, character size, reflective material, and background colour.
They differ from private or personalised plates in one key way: standard plates display your vehicle’s original factory-assigned registration, not a custom mark. They are, by far, the most commonly purchased replacement plate type in the UK, ordered every day by drivers, bodyshops, fleet managers, and car dealers alike.
Getting your number plate wrong in the UK is not a trivial matter. Under the Road Vehicles (Display of Registration Marks) Regulations 2001, displaying a non-compliant plate can result in a fine of up to £1,000, an automatic MOT failure, and in some cases, police action.
💡 CarPlatesPro Compliance Promise: Every plate we manufacture is individually checked against current DVLA regulations and comes with a printed Declaration of Legality, included free with every order.
The current seven-character number plate format has been in use since September 2001 and is broken into three parts: Area Code + Age Identifier + Random Letters (Example: SW26 ABC)
| Part | Example | Meaning |
|---|---|---|
| Area Code | SW | DVLA local office where vehicle was registered |
| Age Identifier | 26 | Year of registration (March to Aug 2026) |
| Random Letters | ABC | Unique vehicle identifier |
New plates are issued twice a year in March and September. The latest 26 plate launched on 1 March 2026 and covers all new vehicles registered until 31 August 2026.
| Plate Type | Dimensions | Suitable For |
|---|---|---|
| Standard Oblong | 520mm x 111mm | Most UK cars, vans, SUVs |
| Motorcycle Square | 228mm x 178mm | All UK motorcycles |
| Short / Small | 279mm x 203mm | Small or classic vehicles |
| Oversize Oblong | 533mm x 152mm | Some larger vehicles |
For the vast majority of UK cars registered after September 2001, the 520 x 111mm oblong is the correct size. If you are unsure, check your existing plate or contact our team and we will confirm the right size for your vehicle.

What is the cheapest legal standard number plate price in the UK?
As of March 2026, CarPlatesPro offers standard number plates from £9.99 per plate, the lowest price available from any DVLA-registered, BS AU 145e certified supplier in the UK. Competitors including Number1Plates (£12.49), Number Plates Next Day (£15.00), and Halfords (£18.00) all charge significantly more for the same road-legal product.
Are online number plates road legal?
Yes, provided the supplier is DVLA registered, the plates are manufactured to BS AU 145e standard, and they include the supplier’s business name and postcode. All CarPlatesPro plates meet these requirements and come with a Declaration of Legality.
What font is used on UK standard number plates?
The Charles Wright font is the only legally permitted typeface for UK number plates. Italic, condensed, or custom fonts are illegal and can result in a fine or MOT failure.
Can I have 3D or 4D characters on a standard number plate?
Yes. Both 3D gel and 4D laser-cut characters are fully legal, as long as they are a single solid shade of black with no gradient or two-tone effect, which has been banned since September 2021.
What is BS AU 145e?
BS AU 145e is the British Standard for vehicle number plates, introduced on 1 September 2021. It requires plates to be manufactured from durable, approved materials and to pass quality and safety benchmarks before use on UK roads. Any plate made after this date must carry the BS AU 145e marking or it is not road legal.
Will a non-compliant number plate fail my MOT?
Yes. MOT testers are required under DVSA guidelines to inspect number plates for compliance. Plates with incorrect fonts, faded characters, wrong background colours, or missing BS AU 145e markings will result in a fail or advisory, depending on severity.
Do I need to provide any documents to buy standard number plates?
Yes. Under UK law, all DVLA-registered number plate suppliers must verify that the purchaser has the right to display the registration. Accepted documents include your V5C logbook, V778 retention certificate, or new keeper supplement. This is a legal requirement. Any supplier selling without this check is not operating legally.
How quickly will I receive my plates?
CarPlatesPro dispatches most orders same or next working day with fully tracked delivery across mainland UK. Express options are available at checkout.
