The number of first aiders required depends on the nature of the work and the number of employees. The Health and Safety (First-Aid) Regulations 1981 require employers to provide adequate and appropriate first-aid equipment, facilities, and personnel.
HSE Guidance
While there's no strict legal formula, the HSE provides guidance:
Low-Risk Workplaces (Offices, Shops, Libraries)
- Fewer than 25 employees — at least one appointed person (someone to take charge of first-aid arrangements and call emergency services)
- 25-50 employees — at least one first aider (holding a valid first-aid at work certificate)
- More than 50 employees — one additional first aider per 100 employees
Higher-Risk Workplaces (Construction, Manufacturing, Warehousing)
- Fewer than 5 employees — at least one appointed person
- 5-50 employees — at least one first aider
- More than 50 employees — one additional first aider per 50 employees
Additional Considerations
- Shift patterns — ensure cover during all working hours
- Remote or lone workers — may need personal first-aid kits and training
- Multi-site locations — each site needs its own provision
- First-aid certificates expire — the standard FAW certificate lasts 3 years
- Annual refresher training is strongly recommended by the HSE
