How to Fit Number Plates: UK Step-by-Step Guide (2026)

Fitting new number plates is a straightforward job that most drivers can do at home in under ten minutes. Whether you are using sticky pads or screws, doing it correctly ensures your plates stay secure, look great, and remain compliant with UK law. This guide walks you through the whole process.

What You Need Before You Start

• Your new number plates (both front and rear)
• Sticky pads or number plate screws and caps — your plates from Car Plates Pro include free sticky pads
• A clean, dry cloth
• Isopropyl alcohol or panel wipe (for a better adhesive bond)
• A drill with a 4mm bit (if screw-fitting)

Method 1: Fitting With Sticky Pads (Recommended)

Sticky pads are the most popular fitting method — no drilling required, no visible screws, and a clean finish. All Car Plates Pro orders include sticky pads free of charge.

1. Clean the surface — wipe the bumper area where the plate will sit with isopropyl alcohol. Remove any dirt, wax, or moisture. Allow to dry completely.
2. Peel and position — remove the backing from the sticky pads and apply them evenly around the back of the plate (corners and centre).
3. Press firmly — position the plate carefully, press firmly all over, and hold for 30 seconds.
4. Allow to cure — for maximum adhesion, leave for 24 hours before washing the vehicle. Avoid power washing the plate area for the first 48 hours.

Important: Sticky pads work best on flat, smooth bumper surfaces. On curved, textured, or recessed bumpers, screw fitting is more reliable.

Method 2: Fitting With Screws

1. Position the plate — hold it in place and mark the four corner drill points with a pen.
2. Drill pilot holes — use a 4mm drill bit. Go slowly on plastic bumpers to avoid cracking.
3. Insert screws — use number plate screws (not standard wood or metal screws) and cover with plastic caps for a clean finish.
4. Check alignment — stand back and verify the plate is level before fully tightening.

Legal Requirements for Fitted Plates

Once fitted, your plates must:

• Be fully visible and readable from the required distance (20 metres)
• Not be obscured by tow bars, bike racks, or accessories
• Be illuminated at the rear — the rear plate light must work correctly
• Not be tilted, bent, or partially obscured

A plate that is not clearly visible can result in a police penalty and an MOT failure. If your plates are cracked, bent, or faded, replace them before your next MOT.

When to Replace Your Number Plates

You should replace your plates if they are:

• Cracked or broken — this is an automatic MOT failure
• Faded or yellowed — the retroreflective material has degraded
• Missing characters or damaged lettering
• Showing signs of peeling (common with older 3D plates)

Order replacement plates at Car Plates Pro from £6.99. Same-day dispatch on orders before 2PM — next working day delivery across the UK.

Frequently Asked Questions

Are sticky pads strong enough for number plates?

Yes. High-quality automotive-grade sticky pads (as supplied with all Car Plates Pro orders) are strong enough to hold a standard number plate under normal UK driving conditions, including motorway speeds. Ensure the surface is clean and dry before fitting.

Can I use any screws to fit number plates?

You should use dedicated number plate screws with plastic security caps. Standard wood screws or metal screws can crack the plate and leave visible damage. Number plate screws are inexpensive and available from Car Plates Pro or any motor accessories store.

Do I need to remove the old plate before fitting a new one?

Yes. Never fit a new plate over an old one. Remove the old plate completely, clean the surface, and fit the new plate cleanly. Doubled-up plates will not pass MOT.

Can I fit number plates myself or do I need a professional?

You can fit plates yourself. It requires no specialist skill or tools. Using sticky pads, the whole job takes about five minutes per plate. If your bumper is an unusual shape or material, a body shop can assist.
