Number Plate Maker: Hull Anlaby Road Supplier Reveals Legality Check System

Key Takeaways

Every registered number plate supplier in the UK is legally required to verify a customer’s entitlement to a registration before producing any plates.
Driving with non-compliant plates can result in a fine of up to £1,000 and an automatic MOT failure.
All plates manufactured after September 2021 must meet the BS AU 145e British Standard – covering everything from character font to background colour and ANPR readability.
Platepress Ltd., based on Anlaby Road in Hull, has built an end-to-end online system that handles the legality check at checkout, so plates are verified before they are ever pressed.
The documents required for proof of entitlement are straightforward – but skipping or faking them carries serious consequences, covered further below.

Getting a new set of number plates sounds simple enough. Pick a size, place an order, wait for delivery. But there is a step sitting quietly in the middle of that process that many drivers do not realise is a legal requirement – and skipping it, whether intentionally or not, can have real consequences on the road.

Registered Suppliers Legally Mandated to Verify Plate Legality and Keep Records

In the UK, number plates cannot simply be printed and sold. Every supplier must be registered with the DVLA under the Register of Number Plate Suppliers (RNPS) – a scheme introduced specifically to control number plate distribution and reduce vehicle crime by tying each set of plates to a verified owner.

That registration comes with obligations. Suppliers are required to check that a customer is actually entitled to the registration they are ordering, and to keep detailed records of every sale. Those records – covering the registration number, the customer’s name and address, and the proof of entitlement provided – can be requested at any time by the police or the DVLA.

A registered supplier that presses plates without seeing the right documents is not just cutting corners; they are breaking the law. Platepress Ltd., the Hull-based number plate maker on Anlaby Road, has built its online ordering system around this requirement, making the document upload part of the standard checkout process rather than an afterthought.

Why Illegal Plates Are a Costly Mistake

Number plate rules are not bureaucratic box-ticking. The consequences of fitting non-compliant plates are both financial and practical.

Up to £1,000 Fine and Automatic MOT Failure

Non-compliant number plates can result in a fine of up to £1,000. Beyond the financial hit, a vehicle fitted with illegal plates will automatically fail its MOT – meaning the car is off the road until compliant plates are fitted and the test is passed again. Both outcomes are avoidable.

What Makes a Plate Non-Compliant

The rules are more specific than most drivers realise. A plate becomes non-compliant if any of the following apply:

Wrong font: The DVLA mandates the Charles Wright font for all number plate characters. No stylised alternatives are permitted.
Altered spacing or rearranged characters: Adjusting spacing to make letters spell a word or phrase is illegal, regardless of how subtle the change appears.
Incorrect background colours: Front plates must have a white background; rear plates must have a yellow background. Note that classic vehicles registered on or before 1 January 1980 may be permitted to display black and silver plates under separate rules.
Non-compliant 3D or 4D characters: Raised gel or laser-cut acrylic characters are legal – but only if they are a single, solid shade of black and conform to all other rules on font and spacing.
Missing supplier details or British Standard mark: Every road-legal plate must display the manufacturer’s details and the BS AU 145e compliance mark.

Each of these rules exists for a reason, and collectively they form the BS AU 145e standard – the benchmark every plate sold in the UK must now meet.

What the Online Legality Check Actually Involves

The verification step is mandatory. Before any registered supplier can produce a plate, they must confirm that the person ordering it has a legal right to that specific registration number.

Documents Accepted as Proof of Entitlement

There are two categories of document a customer needs to provide: proof of identity and proof of entitlement to the registration.

Proof of identity can be satisfied with documents such as a driving licence, passport, or a utility bill. Proof of entitlement means showing one of the following:

A V5C (the vehicle registration certificate, commonly called the logbook)
A V750 (certificate of entitlement, issued when a personalised registration is purchased but not yet assigned to a vehicle)
A Certificate of Entitlement issued by the DVLA for retention of a cherished number

At Platepress, this step happens digitally at checkout – customers upload their documents before the order is confirmed, rather than having to present originals in person.

Why No Registered Supplier Can Skip This Step

The RNPS scheme exists to prevent fraudulent plates being created for vehicles involved in crime – cloned plates being a particular concern. A supplier that processes an order without verified documentation is directly undermining that safeguard, and faces removal from the register as well as potential legal liability. This check is a condition of registration, not a discretionary one.

BS AU 145e: The Standard Every Plate Must Meet

BS AU 145e is the British Standard that governs the physical construction of number plates. It replaced the previous BS AU 145d standard and became mandatory for all plates fitted on or after 1 September 2021.

Key Changes Introduced with BS AU 145e (Mandatory from September 2021)

The updated standard introduced stricter requirements across several areas:

ANPR compatibility: Plates must be reliably readable by Automatic Number Plate Recognition cameras – a requirement for enforcement and traffic monitoring systems.
Durability and reflectivity: Tighter specifications on the reflective materials used, ensuring plates remain legible in varying light conditions over time.
Supplier identification: The supplier’s name, postcode, and the BS AU 145e mark must be permanently displayed on every plate.
Background colour rules confirmed: White front, yellow rear – with no permitted deviations for standard road use.

Any plate made before September 2021 to the older BS AU 145d standard remains legal if it was fitted before the cutoff date. Plates made or fitted after that date must comply with BS AU 145e without exception.

How the Full Process Works End to End

Understanding the compliance requirements is useful context, but what does ordering road-legal plates actually look like in practice?

Build, Upload, Receive

Platepress describes their process in three stages:

Build your plates: Use the online plate builder to enter your registration and preview the full set – front and rear – at true scale. Options include identifier badge style and whether to add a border. Size choices cover standard car plates (520 x 111mm), short and square formats for classic or compact vehicles, and larger oversize plates suited to vans and larger vehicles. Style upgrades – including 3D gel and laser-cut 4D characters – can be added on top of any size, provided the characters remain a solid black in compliance with BS AU 145e.
Upload your documents: At checkout, customers upload their V5C, driving licence, or Certificate of Entitlement. No documents, no plates – Platepress is explicit that they are not permitted to press a plate without verified proof of entitlement.
Printed and posted: Once documentation is approved, both plates are pressed on the same working day using BS AU 145e compliant materials and dispatched together via tracked delivery. Most sets arrive within one to two working days.

The process removes the need to visit a physical showroom while still meeting every legal obligation – the compliance step is built into the checkout rather than added on at the end.

Road-Legal Plates, Posted to Your Door

A mandatory document check, BS AU 145e compliant materials, and same-day production mean there is no trade-off between convenience and compliance. The plates that arrive are road-legal by construction.

For drivers who need a replacement set and want certainty that what lands on the doormat will not fail an MOT or attract a roadside fine, the practical value is clear: the legal check happens before the plate is ever pressed, not after a problem arises.
