EN 131 – Ladders & Work Equipment is the single harmonized European standard that replaces all previous national ladder standards (like BS 2037). It ensures that portable ladders—whether for home DIY or heavy industrial use—meet rigorous stability, durability, and safety criteria.
What Is EN 131?
EN 131 defines the design and testing requirements for portable ladders. The most recent major revision (2018/2019) introduced significant changes, most notably the division of ladders into two distinct classes (“Professional” and “Non-Professional”) and the mandatory use of stabilizer bars for leaning ladders over 3 meters.
The Two Classes of Ladders
Under the current EN 131-2 standard, all ladders are tested to a maximum static load of 150 kg, but durability testing differs:
1. Professional Use
Designed for trade and industrial environments. These ladders undergo a 50,000 cycle durability test. Mandatory for workplace compliance.
2. Non-Professional Use
Designed for domestic/DIY use. These undergo a 10,000 cycle durability test. Suitable for home use only.
Key Parts of the EN 131 Series
The standard is split into several parts covering different ladder types:
| Standard | Coverage |
|---|---|
| EN 131-1 | Terms, types, and functional sizes (dimensions). |
| EN 131-2 | Requirements, testing, and marking (Load & Slip tests). |
| EN 131-3 | User Instructions and safety labeling. |
| EN 131-4 | Single or multiple hinge-joint ladders. |
| EN 131-6 | Telescopic Ladders (Critical for safety). |
| EN 131-7 | Mobile ladders with platforms (Warehouse steps). |
Critical Safety Requirements
- ✅ Stabilizer Bar: Any leaning ladder longer than 3 meters must have a stabilizer bar at the base to prevent sideways tipping.
- ✅ Slip Resistance: Feet and rungs are tested on slippery surfaces to ensure grip.
- ✅ Torsion Test: Ensures the ladder does not twist excessively when a user climbs it.
- ✅ Opening Restraints: Stepladders must have durable straps or bars to prevent the legs from splitting apart.
How to Check for Compliance
Before purchasing or using a ladder, check for these indicators:
- The Label: Look for the EN 131 marking and the specific classification (“Professional” or “Non-Professional”).
- Max Load: It must state a maximum load of 150 kg (anything less, e.g., 90 kg, is non-compliant/obsolete).
- Production Date: Ensure the ladder was manufactured to the latest revision (post-2018 is safest).
- User Manual: EN 131-3 requires a manual with safety pictograms to be included.

Frequently Asked Questions
Can I use an old BS 2037 ladder at work?
Technically, standards are not retroactive laws. However, safety inspectors (like HSE in the UK) generally expect equipment to meet current good practice. Using obsolete ladders (Class 1 or Class 3) is a liability risk if an accident occurs. Upgrading to EN 131 Professional is strongly recommended.
Do step stools fall under EN 131?
No. Small step stools (typically under 1 meter) are covered by a different standard: EN 14183.
What about telescopic ladders?
Telescopic ladders must strictly comply with EN 131-6. Due to their mechanism, they have specific requirements for “distance between rungs” (to prevent trapped fingers) and locking indicators.
Do I need to buy the official standard?
Yes. If you are a manufacturer, safety manager, or importer, owning the official standard is required to verify your products’ compliance and maintain your safety audit trail.
