Wiper blades are one of those car parts that are easy to overlook — until they stop working properly. In the UK, where rain is a near-constant companion, worn wiper blades aren't just an inconvenience; they're a safety hazard. Here's how to know when it's time for a replacement.
How Long Do Wiper Blades Last?
Most wiper blades last between 6 to 12 months, depending on usage, climate, and blade quality. UK drivers tend to use their wipers more frequently than those in drier climates, which can shorten blade life. As a general rule, inspect your blades every six months — a good habit to pair with your MOT or seasonal service.
Signs Your Wiper Blades Need Replacing
Don't wait until you can't see through your windscreen. Watch out for these warning signs:
- Streaking – If your blades leave streaks of water rather than clearing the screen cleanly, the rubber edge is worn or damaged.
- Smearing – A smeared, greasy film across the windscreen often means the blade is no longer making proper contact.
- Skipping or chattering – A juddering motion across the glass indicates the blade has lost its flexibility, often due to cold weather or UV degradation.
- Squeaking – Persistent squeaking, even on a wet screen, suggests the rubber has hardened or the blade is misaligned.
- Visible damage – Cracks, tears, or bent frames are a clear sign the blade needs to go.
- Poor wet-weather visibility – If you're struggling to see clearly in rain, your blades may simply be past their best.
What Causes Wiper Blades to Wear Out?
Several factors accelerate blade wear:
- UV exposure – Sunlight degrades rubber over time, even in the UK.
- Frost and ice – Running wipers on a frozen screen, or using them to clear ice, causes rapid deterioration.
- Dry use – Using wipers on a dry screen creates friction that wears the rubber edge quickly.
- Debris – Grit, leaves, and road debris can nick or tear the blade edge.
The MOT and Wiper Blades
Wiper blades are checked as part of the UK MOT test. A blade that smears, streaks, or fails to clear the windscreen adequately can result in a failure. Replacing your blades before your MOT is a simple, low-cost way to avoid an unnecessary fail.
How to Check Your Wiper Blades
A quick check takes less than a minute:
- Lift the wiper arm away from the windscreen.
- Run your finger along the rubber edge — it should feel smooth and flexible, not cracked or stiff.
- Look for any visible splits, tears, or bent sections in the frame.
- Run your wipers on a wet screen and observe the result — any streaking or skipping means it's time to replace.
