20% Window Tint – What You Need to Know
Thinking about a 20% tint? It blocks 80% of sunlight, keeping the cabin cooler and more private. Most drivers choose it for rear windows because it offers strong heat reduction without looking too dark.
Legal limits for 20% tint in the UK
The UK law says front side windows must let at least 70% of light through. That means a 20% tint (which only lets 20% in) isn’t legal on the driver’s side or passenger side front windows. Rear windows and the back windshield can go darker, so a 20% film is fine there.
If you install a 20% tint on the front, you risk a fine and a failed MOT. Always check the VOSA guidelines before you commit.
Choosing the right 20% film
Not all 20% films are created equal. Dyed films are cheap but fade over time. Metallic films reflect heat but can interfere with radio signals. Ceramic films offer the best UV protection and durability without signal loss, though they cost more.
Carbon films sit between dyed and ceramic. They block heat well and keep a matte look that many car owners prefer.
When you compare brands, look for a warranty of at least five years. A good warranty shows the manufacturer trusts the film’s longevity.
Installation matters as much as the film itself. A bubble‑free finish requires a clean glass surface, proper temperature, and a skilled installer.
At Nottingham Car Wraps & Styling we use premium ceramic and carbon films that meet the 20% light transmission rating. Our technicians prep each pane with professional tools, ensuring a smooth, long‑lasting result.
We also offer a colour‑matching service. Want a slightly darker look for the rear windows? We can blend films to hit the exact shade you like while staying within legal limits.
Cost for a full rear‑window 20% tint ranges from £150 to £300, depending on film type and car size. The price includes prep, installation, and a one‑year care kit.
After the job, we give you a simple cleaning guide: use a pH‑balanced glass cleaner and a soft microfiber cloth. Avoid ammonia‑based products, as they can damage the film.
If you notice any bubbles or peeling within the warranty period, call us straight away. We’ll inspect the work and replace the film if needed.
Choosing a reputable local shop means faster service and easier follow‑up. No need to ship the film across the country and hope for a perfect fit.
