If you’re thinking about darkening your windows, stop and read this first. Getting the right tint isn’t just about style – it’s about staying on the right side of the law. In the UK, each window has a specific VLT (Visible Light Transmission) limit, and breaking it can land you a fine or even a forced removal.
Front windscreen tint is the strictest. You’re only allowed a 5% VLT strip at the top, mainly for glare reduction. Anything darker is an instant no‑go. Front side windows can go up to 70% VLT. That means the tint can block up to 30% of light, but no more. Rear side windows and the back windscreen are more relaxed – you can go down to 35% VLT if you want a darker look.
Before you buy, grab a simple tint meter or visit a local garage that offers testing. The device shines a light through the glass and tells you the exact VLT. It’s cheap, quick, and saves you from a nasty court summons. If you already have tint, get it measured right away. Some installers claim their product is legal, but a meter will give you the hard proof you need.
Another easy check: look at the tint’s certification label. Reputable brands include a CE marking and the VLT percentage. If the label is missing or looks homemade, it’s probably not road‑legal.
Many people think “darker = cooler,” but that’s not how the law works. Going below the legal VLT on the front side windows is the fastest way to get a penalty. Also, don’t assume a tint that looks good on your buddy’s car is automatically legal for yours – VLT limits can vary by vehicle type and even by region.
Some drivers try to cheat by applying a thin film over an already legal tint, hoping the extra layer won’t be noticed. That’s risky – the meter will still read the total light blocked, and you could end up with a double fine.
Finally, remember that police can pull you over for any reason and then check your windows. If the tint is borderline, they may ask you to step out and get a reading on the spot.
Bottom line: stick to the legal VLT numbers, get a professional measurement, and keep the certification handy. That way, you enjoy the sleek look without worrying about tickets.
