About the sign

A no unauthorised access sign tells visitors, passers-by and delivery drivers that entry to the site is restricted to those with permission. It is typically posted at site gates, hoarding panels, temporary fencing and any entrance where the public might otherwise walk in.

A well-placed sign reduces the risk of accidents involving people who are unfamiliar with the hazards on a working site. It also makes it straightforward for site managers and security staff to challenge anyone who should not be there, because the boundary is clearly marked.

Just a Sign offers construction site signs in several designs, with a choice of sticker, indoor sign or outdoor sign to suit your situation. Pick the size that matches your viewing distance, or open the chat and ask our AI designer to adjust the wording, layout or any other detail before you order.

Questions and answers

Where should I put a no unauthorised access sign on a construction site?

Fix it at every point where someone could enter: main gates, pedestrian gaps in hoarding, temporary fencing panels and any secondary access routes. Position it at eye level so it is easy to read without stopping.

Should I choose an indoor sign or an outdoor sign?

For site hoardings, gates and fencing exposed to rain and sun, choose the outdoor sign, which carries a UV laminate designed to hold up through changing weather. The indoor sign suits site offices, welfare units and covered walkways. Stickers work well on smooth, flat surfaces such as metal gates or site cabins.

Can I change the wording on the sign?

Yes. Open the chat with our AI designer and describe what you need β€” a different instruction, a company name, a site reference or any other adjustment. The designer will update the sign before you place your order.

What size sign do I need for a construction site entrance?

That depends on how far away people will be when they first see it. Choose a larger size for main vehicle gates viewed from a distance, and a smaller size for pedestrian entrances where people walk right up to the hoarding.

Can I order more than one design for the same site?

Yes. Many sites use a combination of designs β€” for example, a larger sign at the main vehicle entrance and smaller signs at pedestrian access points. You can add different designs and sizes to your basket in a single visit.
