🛡️ New British Windscreen Repair Standards: BS AU 242b:2022
What is BS AU 242b:2022?
The British Standards Institution (BSI) released updated guidance for windscreen repair and replacement under the new BS AU 242b:2022 standard. This came into effect in March 2022, fully replacing the previous version by March 2023.
This revised standard aims to modernise how windscreen damage is assessed and repaired—improving safety, enabling more repairs (rather than full replacements), and reducing waste.
Why This Matters for You
Under the new regulations:
- More types of windscreen damage may now be safely repaired, saving time, money, and reducing environmental impact.
- Repairs are more carefully evaluated based on location and severity.
- Camera zones and ADAS sensors are now strictly non-repairable areas to protect vehicle safety systems.
Key Updates in BS AU 242b:2022
✅ What’s Changed:
- Repairable damage is now clearly defined by size and location.
- Windscreens are divided into two repair zones:
- Zone A: Directly in front of the driver (stricter rules)
- Zone B: The rest of the windscreen
- New inspection and finish quality requirements ensure repairs don’t affect driver vision.
- Technicians must now meet updated training, assessment, and record-keeping standards.
❌ Areas That Cannot Be Repaired:
- Any ADAS sensor zones
- Camera zones
- Damage that interferes with driver visibility or exceeds allowed limits
📏 Repair Zone Criteria
| Zone | Max Damage Size | Repairable? |
|---|---|---|
| Zone A (Driver’s View) | Up to 20mm | ✅ if not in camera/ADAS zones |
| Zone B (Rest of Windscreen) | Up to 40mm, or cracks up to 150mm | ✅ |
| Camera/ADAS Zones | Any size | ❌ Replacement required |
🔍 Post-repair, the damaged area must be:
- Flush with surrounding glass
- Invisible or barely visible
- Less than 10mm in diameter
