How to Stop Number Plates Falling Off Your Car (Permanent Fixes That Actually Work)

December 21 2025, by Reece Dennis, 6 min reading time

In this guide, we’ll explain why number plates fall off, how to stop it happening for good, and the best fixing methods for both standard number plates and 4D number plates.

Why Do Number Plates Fall Off?

Most number plates don’t fall off randomly — there’s usually a clear reason. The most common causes include:

• Low-quality adhesive pads losing grip over time

• Incorrect or missing screws

• Old, cracked, or warped number plates

• Poor fitting on curved bumpers

• Pressure from car washes and harsh weather

Heavier plates, such as 4D number plates, can also expose weak fixings that may have worked fine on cheaper or thinner plates.

Is It Illegal to Drive Without a Number Plate?

Yes. In the UK, number plates must be securely fixed and clearly visible at all times. Driving without one can result in:

• A £100 on-the-spot fine

• MOT failure

• Being stopped by the police

That’s why it’s important to fix the issue properly, not temporarily.

Best Ways to Stop Your Number Plate Falling Off

Use Proper Number Plate Screws (Most Secure Method)

Using proper number plate screws is still the most reliable way to secure a plate, especially for long-term use.

Best practice:

• Use stainless steel screws to prevent rust

• Don’t overtighten, as this can crack acrylic plates

• Use screw caps for a clean, professional finish

This method works perfectly for both standard number plates and 4D plates.

Use High-Quality Adhesive Pads (If You Don’t Want to Drill)

If you prefer a no-drill look, adhesive pads can work — but only if they are automotive-grade. Cheap sticky pads are one of the main reasons number plates fall off.

How to make adhesive pads last:

1. Clean the bumper and plate thoroughly with alcohol wipes

2. Use at least 6 to 8 strong adhesive pads

3. Press firmly for at least 60 seconds

4. Leave the car parked for 24 hours before driving

This method works best with premium, rigid plates, including 4D number plates.

Replace Old or Damaged Number Plates

If your plate is cracked, bent, or brittle, no fixing method will last long-term. Old plates simply don’t bond properly or hold screws securely.

Upgrading to:

• Standard UK number plates (lightweight and fully compliant)

• 4D number plates (thicker, stronger, premium finish)

…will dramatically reduce the risk of your number plate coming loose again.

Don’t Mix Fixing Methods Incorrectly

One of the most common mistakes is using one screw and a couple of sticky pads. This creates uneven pressure and almost guarantees failure.

Always choose one method:

• All screws

• Or all adhesive pads

Never mix them poorly.

What’s the Best Way to Secure 4D Number Plates?

Because 4D number plates are heavier than standard acrylic plates, we recommend:

• Screws with rubber washers for maximum security

• Or high-strength automotive adhesive pads fitted correctly

This ensures your 4D plates stay secure at speed and in all weather conditions.

Quick Checklist to Stop Your Number Plate Falling Off

• Use quality fixings, not cheap adhesive pads

• Clean all surfaces before fitting

• Match the fixing method to the plate type

• Avoid overtightening screws

• Check your plates regularly

Final Thoughts

If your number plate keeps falling off, it’s almost always due to poor fitting or low-quality fixings. Using the correct installation method and a high-quality plate will solve the problem permanently.

Whether you’re fitting standard number plates or upgrading to 4D number plates, securing them properly will save you time, money, and potential fines.
