No Unauthorised Entry Sign | UK Health & Safety Sign


The No Unauthorised Entry Sign is a critical safety solution used on construction sites, industrial facilities, and secure zones to control access and prevent trespassing. It uses a bold ISO 9001-compliant red prohibition symbol combined with clear “No unauthorised entry” text to immediately inform and deter unapproved access.

These signs are essential for maintaining site safety and ensuring compliance with UK health and safety regulations. Whether mounted on fences, hoardings, or temporary barriers, they provide a strong visual warning to employees, visitors, sub-contractors, and the public.

Available in a variety of sizes and durable substrates including Corriboard, Foamex, and self-adhesive vinyl, this sign is suitable for temporary or permanent use in high-traffic areas and restricted zones.


🔧 Technical Review

This prohibition sign is a standard across construction and infrastructure projects in the UK. Its ISO-style hand symbol and direct wording create a universal and non-negotiable message to halt entry.

The durable build ensures the sign remains legible and effective even when exposed to harsh weather, dust, or handling. It’s designed for mounting on stanchion posts, walls, or site fencing with ease.
