How Long Do Number Plates Last and When Should You Replace Them?

Number plates are designed to withstand years of daily driving, but like any part of your vehicle, they won’t last forever. Exposure to sunlight, weather, road salt and regular wear can eventually affect their appearance and legality.

If you’re wondering whether your plates need replacing, here’s everything you need to know.

How Long Do Number Plates Last?

A high-quality number plate can typically last anywhere from 5 to 10 years or more, depending on:

  • Material quality
  • Manufacturing standards
  • Weather exposure
  • Vehicle usage
  • Cleaning methods
  • Storage conditions

Vehicles that spend most of their time outdoors are likely to experience faster plate deterioration than those kept in a garage.

What Causes Number Plates to Wear Out?

Over time, number plates are exposed to:

UV Sunlight

Constant exposure to sunlight can cause:

  • Fading
  • Yellowing
  • Reduced reflectivity

Rain and Weather

The UK’s climate can gradually break down the materials used in older plates.

Road Salt

Winter road salt can accelerate deterioration and affect the reflective backing.

Stone Chips and Impact Damage

Everyday driving can cause chips, cracks and damage to the plate surface.

Car Wash Chemicals

Frequent use of strong cleaning products can contribute to peeling and delamination over time.

Signs Your Number Plates Need Replacing

Cracks and Damage

Small cracks can quickly worsen and may eventually affect the readability of the registration.

If a crack runs through any of the characters, replacement is strongly recommended.

Delamination

Delamination occurs when the reflective backing begins to separate from the acrylic face.

This can make the registration difficult to read and may result in MOT issues.

Fading Characters

If the characters are becoming difficult to read due to fading or discolouration, the plate should be replaced.

Yellowing or Discolouration

Older plates often develop a yellow or cloudy appearance, particularly on the front plate.

Peeling Reflective Backing

The reflective material should remain smooth and intact.

Peeling or bubbling can reduce visibility and affect compliance.

Can Old Number Plates Fail an MOT?

Yes.

Number plates are checked during an MOT inspection and must be:

  • Clearly readable
  • Securely attached
  • In good condition
  • Free from excessive damage
  • Compliant with legal requirements

Damaged, faded or deteriorated plates may result in an MOT failure.

Is It Illegal to Drive With Worn Number Plates?

If the plate becomes difficult to read or no longer complies with UK regulations, it may be considered illegal.

Potential consequences include:

  • MOT failures
  • Vehicle defect notices
  • Requests to replace the plate
  • Fines of up to £1,000

This is why replacing worn plates promptly is important.

Should You Replace Both Plates Together?

In most cases, yes.

Even if only one plate is damaged, the other plate is often of a similar age and condition.

Replacing both plates provides:

  • A consistent appearance
  • Improved visibility
  • Better long-term value
  • Enhanced vehicle presentation

How Often Should You Inspect Your Number Plates?

It’s a good idea to inspect your number plates every few months.

Look for:

  • Cracks
  • Fading
  • Peeling
  • Discolouration
  • Loose fixings
  • Damage to characters

Early replacement can help prevent MOT failures and keep your vehicle looking its best.
