Before you can fit a replacement number plate, you will need to remove the existing one. Simply unscrew the holding screws and remove the old plate. As can be seen in the image above, the area under the number plate will be dirty. So now is a perfect time for a real clean.

Note: Keep your old number plate handy, you’ll need it later.

Number Plate Drilling Guide

Fitting your number plates using screws is an easy process with a few simple steps. First you’ll need to a template to ensure the holes are in the right place. And you’ll want to avoid damaging your new plates when you drill them. Simply follow the steps below and you’ll soon be screwing the plate to your car.

Ordinarily this guide is suitable for both our Standard 2-Part & Hybrid 3-Part number plates.

Make Drilling Template

Mark your drilling points on your new number plate
Before you starting drilling, your first step should be to mark where the holes need to be. This is where your old number plate comes in handy.

When drilling you’ll start at the back to avoid damaging the plate. So place your new number plate flat on your worktop, with the rear facing upwards. Now position the old one on top and line them up so that their centres match. Next, using a black marker and using the old screw holes, make a mark or cross on the new plate.

Mask Drilling Points

Mask the number plate drilling points
When drilling a hole, you only get one chance to get it right. So we’re going to use a common technique of using masking tape to help stop the drill slipping. Apply a small piece of masking tape on top of your drilling marks. Masking tape is thin enough, so you should still be able to see your mark through it.

Note: If your marks aren’t visible, re-use your old plate and mark the drilling points on top of the masking tape.

Drill Holes Carefully

Drill from the rear of the number plate
Use a 6mm diameter acrylic bit for drilling your holes. Carefully position the drill at one of your drilling points. Start the drill and gently begin to make a hole. Allow the bit to do the work, avoid applying to much pressure.

Remember: Drill from the rear of number plate to the front. Placing wood underneath the number plate might help avoid damage.

Deburr & Smooth Holes

Remove tape and deburr the holes in the number plate
Once you have drilled your holes remove the masking tape from the plate. If there’s any burrs or lumps, take them off. This will help your screws fit flush with the plates surface. Now you’re ready to fit the plate to your vehicle.

Screw Number Plate to Vehicle

Screw your number plate to the vehicle
Position the plate in the correct location on the vehicle by partially attaching screws to both holes. Now carefully tighten up your fixings, ensure you don’t over tighten them. Finally polish the plate using circular motions with a soft cloth to remove finger prints or dirt.

Remember: Select coloured screw caps that correspond with the holes location on the number plate. Don’t use cap colours which alter the appearance of the registration mark.
