Guide: How do I Fit a Number Plate on My Car

Wondering how do I fit a number plate to my car? The process might look tricky, but it’s actually a straightforward DIY task you can complete at home with just a few basic tools. While you can pay a garage or specialist to do it, fitting your number plate yourself saves money and gives you peace of mind—just be sure to follow the correct method to stay compliant with UK road laws.

Tools Required

Before starting, gather the following tools and equipment:

• Phillips head screwdriver
• Electric drill with 4mm and 6mm drill bits
• Scrap wood (to protect the plate when drilling)
• Cleaning cloth and suitable cleaner
• Double-sided automotive tape (for the no-drill option)

Step-by-Step Guide: Fitting a Number Plate

Step 1: Remove the Old Plate

If your car already has number plates fitted, you’ll need to take them off first. Use a Phillips screwdriver to undo the screws. If adhesive pads were used, gently peel the plate away—be careful not to damage the car’s paintwork. Once removed, clean the surface thoroughly so the new plate sticks or screws on securely.

Step 2: Position the New Plate

Hold the new number plate in position on your car. If the old plate had screw holes, try to align with these for a neater fit. You can use masking tape or a marker to mark the drilling spots. A correctly positioned plate ensures your car looks professional and meets legal display standards.

Step 3: Drill the Holes

Place scrap wood behind the number plate to protect it from cracking. Carefully drill holes from the back to the front using a 4mm or 6mm bit. Take your time—rushing could damage the acrylic. Important: if your number plate has 3D gel or 4D letters, never drill through or near the raised characters.

Step 4: Attach the New Plate

Once drilled, align the plate with your vehicle’s mounting points. Insert the screws by hand first to avoid cross-threading, then tighten them gently with a screwdriver. Do not overtighten as this can crack the plate.

Alternative Method: Fitting Without Drilling

If you prefer not to use screws, you can fit your number plate using double-sided automotive tape. Clean the surface thoroughly, apply strips of tape evenly across the back of the plate, then press it firmly onto the vehicle. Hold pressure for around a minute to ensure adhesion. Avoid washing the car for 24 hours afterwards.

Final Checks

After fitting your number plate, check that:

• The plate is level and securely fixed.
• All characters are clearly visible and unobstructed.
• The plate meets UK legal standards (correct font, spacing, and BS AU 145e mark).

By following this guide, you’ll know exactly how to fit a number plate to your car—whether you use screws or adhesive tape. Done correctly, your new plate will be secure, road-legal, and looking great.
