Deter unauthorised access with this high‑visibility No Unauthorised Persons sign, part of our Access & No Entry collection. Manufactured in the UK from weatherproof materials, it's built to endure outdoor conditions on gates, fences, doors or hoardings. Featuring a bold ISO 7010 prohibition pictogram and clear message, it supports compliance with the Health & Safety (Safety Signs & Signals) Regulations 1996 and HSE site safety guidelines. Ideal for construction sites, warehouses, private estates, plant rooms, and restricted zones, this sign helps prevent accidents and unauthorised entry. Available in a range of durable substrates—rigid plastic, recyclable plastic or aluminium composite—with UV resistance and low maintenance. Supplied ready-to-fix with self-adhesive backing or pre-drilled holes, it’s a reliable solution for visible safety signage, access control and legal compliance across UK premises.
