The law says that every business must have a policy for managing health and safety.
A health and safety policy sets out your general approach to health and safety. It explains how you, as an employer, will manage health and safety in your business. It should clearly say who does what, when and how.
If you have five or more employees, you must write your policy down. If you have fewer than five employees you do not have to write anything down, but it is useful to do so.
You must share the policy, and any changes to it, with your employees.
