A broken rear window is more than just a nuisance. Unlike a windscreen crack that might still let you drive for a short while, damage to your rear glass usually means your car is unsafe and vulnerable until it's fixed.
Whether it's been smashed in an accident, broken into by thieves, or hit by flying debris, getting your rear window replaced quickly is essential.
At UK Windscreens, we know how frustrating this situation can be. That's why we've put together this guide to answer the most common questions about rear window replacement, including:
It's easy to underestimate the impact of a broken rear window, especially if the damage looks small. But the rear window plays an important role in both safety and comfort. Ignoring it can cause several problems:
A broken rear window is an open invitation for theft. Even if your boot is empty, opportunists may assume valuables are inside.
Rainwater, wind, and condensation can quickly cause damage to upholstery, electrics, and the overall condition of your car.
A cracked or smashed rear window can distort your view and make reversing or checking behind you dangerous.
With broken glass, driving becomes noisy and uncomfortable – and in cold weather, it's even worse.
In short, your rear window isn't something you can "leave for later" – it needs to be replaced as soon as possible.
One of the biggest concerns for drivers is cost.
The average price of rear window replacement in the UK is between £300 and £650, depending on your vehicle make and model.
