Window tint
Rear sides
No tint
The law
Front windscreens must let through at least 75% of light, front side windows at least 70%. Rear glass has no limit. Road Vehicles (Construction and Use) Regulations 1986, reg. 32.
The test measures glass and film together. Most cars leave the factory with slightly tinted glass, so a film rated at the limit can still fail on the car — we measure before fitting.
Darker is not better
Heat and UV rejection come from the film’s construction, not from how dark it is — 3M Crystalline Series rejects 99.9% of UV at every level in the range, and its lightest shade still rejects 46% of solar energy. A dark cheap film will not out-perform a light good one.
Not sure which is right?
Tell us the car and how you use it and we will recommend a film.
The car above is an illustration, not a photograph of your vehicle, and on-screen darkness is a guide only — tint reads differently by glass type, lighting and angle. Figures are the manufacturers’ own: 3M (6mm, 73% VLT automotive green glass (ANSI/NFRC 200)) · XPEL (3mm clear glass (EN 410)) · SunTek (6mm clear glass (NFRC)). Brands test to different standards on different glass, so their numbers are not directly comparable with each other.
Tell us the car and the finish you want — photos help — and we’ll come back with a fixed price and the next available slot.
