Understanding the Non-Conductive Nature of Glassfibre Ladders

May 15, 2025

When it comes to working at height in electrical environments, safety is absolutely critical. That’s where glassfibre ladders – often referred to as fibre glass ladders – come into their own. Known for their non-conductive properties, glassfibre ladders have become the trusted choice for electricians, utilities, and facilities maintenance teams across the UK.


However, it's important to recognise that not all glassfibre ladders offer the same level of electrical protection.

Why Glassfibre?

Glassfibre is widely used in ladders because it is an excellent insulator. Unlike aluminium or steel, it doesn’t conduct electricity, significantly reducing the risk of electric shock when working near live sources.


But just because a ladder is made of glassfibre doesn't automatically mean it has been properlydielectric tested or certified for high-voltage environments. Many cheaper glassfibre ladders available in the market are designed for general trade use and are not tested to EN131 Professional standards, sometimes offering only basic non-conductive properties.


What to Watch Out For

While some ladders are simply described as "fibre glass" or "non-conductive," they may not be tested to withstand the voltage exposure required for work near live electricity.


For example:

  • Some imported fibreglass ladders on the market are only tested to low-voltage scenarios.
  • Others may not be formally tested at all, relying purely on the natural insulating properties of the material without independent certification.

For Health & Safety Managers and procurement teams, assuming all fibre glass ladders offer equal protection could expose workers to serious risks.


Always look for dielectric testing certification and EN131 Professional compliance when sourcing ladders for electrical work.

Choosing the right equipment for working at height can significantly impact site safety, task efficiency and long-term value. At Lyte Ladders & Towers, we manufacture a full range of standard access equipment certified to the latest safety standards, as well as bespoke access solutions tailored to solve complex or industry-specific challenges. But how do you know which is right for your needs? In this post, we explore the pros and cons of standard vs bespoke solutions, and how to make the best choice for your business. Standard Access Products: Certified and Ready to Use Our standard ladders, steps, podiums and towers are independently tested and certified to the relevant standards (such as EN131 or EN1004 ), ensuring they meet strict safety and performance requirements for regular trade and industrial use. ✔️ Advantages of Standard Products Fully Certified: Products like our MagnaStep range are EN131 Professional certified, which is reassuring for both Health & Safety teams and users. Faster Lead Times: Manufactured in volume at our UK factory, standard items are available with shorter turnaround times and higher stock availability. Cost-Effective: Ideal for bulk purchase for use across large teams or multi-site operations. Widely Applicable: Suitable for general use across construction, maintenance, utilities, and facilities management. ⚠️ Limitations One-Size-Fits-All Design: May not suit specialist tasks or restricted environments. Workarounds Can Introduce Risk: Using the wrong type of ladder or adapting it on site can lead to unsafe practices. Bespoke Access Solutions: Built Around Your Challenge Not all jobs fit within a standard set of dimensions, and that’s where Lyte’s bespoke design service comes in. From access towers for the transport industry to maintain their vehicles to compact platforms designs to fit in confined portable buildings and telecoms pole ladders for utilities , we work closely with customers across multiple industries to design safe, purpose-built solutions. View some of our recent bespoke projects here: 👉 Bespoke Products Gallery ✔️ Advantages of Bespoke Solutions Tailored for Your Task: Designed specifically to fit the working environment, user needs and operational requirements. Solves Access Challenges Safely: Reduces reliance on unsafe workarounds or modifications. Long-Term Value: Bespoke solutions can reduce downtime, improve productivity, and enhance operator safety over time. Built and Tested In-House: Even though many bespoke products don’t fall under a formal certification like EN131, we apply our rigorous in-house testing protocols to ensure every product is safe, stable, and fit for purpose. Learn more about our testing process: 👉 Bespoke Access Testing & Development ⚠️ Considerations Longer Lead Times: Bespoke items require consultation, design approval and testing. Not Always Certified: As these products don’t always align with a defined European standard, they cannot carry an EN131 badge, however they are still tested to the highest standards by our in-house team.

When the bell rings for the last time in July, it signals more than the start of summer holidays. For facilities managers across schools, colleges, and universities, it marks the start of a critical maintenance window. With corridors clear, classrooms empty, and fewer safeguarding restrictions in place, the summer break is the ideal time to tackle planned maintenance and health & safety improvements. From electrical inspections to ceiling repairs and painting projects, much of the work that keeps educational buildings safe, functional, and compliant happens while pupils and staff are away. At Lyte, we understand the demands of this compressed maintenance period, and our British-made access equipment is trusted by facilities teams across the UK education sector to get the job done safely and efficiently. Common Tasks During the Summer Break Facilities and estates teams often use the holidays to: Carry out electrical testing and lighting upgrades Clean or repair HVAC systems in ceiling voids Paint and redecorate classrooms and corridors Service fire alarms, CCTV, and security systems Install new whiteboards, projectors, and cabling Inspect and repair roof areas, guttering, and external cladding Whether it’s reactive work or part of an annual PPM schedule, reliable access equipment is essential.
