NASC Unveils 2025 Safety Report
16th June 2025
At SIMIAN, safety isn’t just something we endorse; it drives everything we do. The NASC Safety Report 2025, built on 2024 data, highlights some outstanding progress for our sector, milestones we share with pride. And while there’s a record of achievement, our commitment to continuous improvement remains stronger than ever.
Findings in Numbers
Key statistics from the NASC Safety Report 2025:
- Accident Frequency Rate (AFR): 0.20
The lowest AFR ever recorded in NASC’s 50-year reporting history - Accident Incident Rate (AIR): 3.75
Also a record low, reinforcing a strong trend in safer operations - 16% reduction in accidents, even with a 17% increase in operatives year-on-year
- 22% growth in NASC membership, with 54 new contractor companies and 2,775 additional operatives included in the safety data pool
- 100% RIDDOR reporting by full contractor members, proving full transparency and high accountability
- One fatal accident reported—involving an experienced inspector—currently under investigation, emphasising that vigilance remains crucial


A Safer Industry for All
- Lowest accident rates ever recorded
The report reveals an Accident Frequency Rate (AFR) of 0.20 and an Accident Incident Rate (AIR) of 3.75, both the lowest in NASC’s 50 years of reporting - Risk remains high but falling
Safety figures improved despite a 22% increase in membership during the year, including 54 new contractors and 2,775 additional operatives - Consistent RIDDOR reporting by all members
Full partnering contractor members maintained crystal‑clear transparency—a reflection of a mature, responsible safety culture - New focus areas: mental health & technology
Uptake of digital tools like TG20/TG30 and new mental health resources (e.g. pocket-install user guides, technical advice lines) are being credited as contributing to safety improvements
At SIMIAN, we are passionate about the safety and professionalism of our industry, and we have been working tirelessly to improve safety standards for those working as scaffolders and working at height. Our training courses and apprenticeships both contribute to helping scaffolders to work safely and manage the risks associated with their work.
We are proud of the work we do with NASC and the contribution that we have made to improving safety. The findings are the culmination of many years of hard work across the scaffolding and access industry to improve standards through the right training and adhering to health and safety guidelines to make our sector as safe as it can be.
Where safety is concerned there is always more that can be done and we will continue to work with NASC, our clients, and students to capitalise on the excellent work which has already had a positive impact, and to continue to improve standards.
