No. The law says your first aid arrangements must be “adequate and appropriate” and based on a first aid needs assessment – it does not force you to use any particular kit standard. BS 8599‑1 is a British Standard that sets out structured contents for small, medium and large workplace first aid kits, which many employers use because it gives a clear, modern benchmark to work from.

We treat BS 8599‑1 as a very useful starting point – especially when you want consistency across several sites – but we still adjust kit size, quantities and any specialist kits around the risks in your actual workplace.
