Construction Site Signs: Temporary & Permanent Requirements

8 min readIncludes checklist
Read Guide

Enforce site safety protocols and ensure full compliance with our comprehensive range of Mandatory Signs. These blue-and-white circular signs deliver a direct instruction: they tell occupants what they must do. They are a cornerstone of UK health and safety legislation, essential for communicating non-negotiable rules such as PPE requirements and hygiene protocols.

Our mandatory signage complies with BS EN ISO 7010. By using universally recognized white pictograms, these signs provide an authoritative command understood at a glance. In accordance with the Health and Safety at Work Act 1974, employers have a legal duty to provide clear instructions. Placing these at every entry point to a hazardous zone ensures your safety protocols are always visible, legible, and fully compliant.
