Overview
The short answer, then the detail.
A No Unauthorised Entry sign keeps people who have no reason to be there out of the area. It uses the ISO 7010 P004 no thoroughfare symbol. Sizes A3 landscape (420 × 297 mm) to A1 landscape (841 × 594 mm) in 3.5mm Correx, 3mm Foamex and 3mm Dibond aluminium composite. UK mainland delivery £7.95, free over £99; no VAT added.
Use this sign where you need to say "No Unauthorised Entry" clearly. It keeps people who have no reason to be there out of the area, and is commonly fitted in building sites, compounds, plant rooms and private land. The design uses a red prohibition circle with a white text panel, with the ISO 7010 P004 (No thoroughfare) symbol.
Under the Construction (Design and Management) Regulations 2015 the principal contractor must take steps to prevent unauthorised access to the site, and safety signs are part of that. Keep a note of where each sign is fitted as part of your records.
No Unauthorised Entry Sign: sizes and materials
Materials: 3.5mm Correx fluted polypropylene, light and waterproof, ideal for temporary and site signs, 3mm Foamex (rigid PVC foam board), light and easy to fix indoors or for short-term outdoor use and 3mm Dibond aluminium composite, rigid and weatherproof for long-term outdoor use. For signs that stay outdoors for a long time, Dibond is the most durable choice.
Sizes and viewing distance: A3 landscape (420 × 297 mm) (reads at about 12 m); A2 landscape (594 × 420 mm) (reads at about 17 m); A1 landscape (841 × 594 mm) (reads at about 24 m). As a guide we allow about 1 metre of viewing distance for every 25mm of sign height, based on the distance-factor method in ISO 3864-1, so choose a bigger size for long corridors, yards and car parks.
Where to put it: At every gate and entrance and along the boundary.

Which size do I need?
A safety sign must be large enough to read from where people will see it. Our conservative guide, based on the distance-factor method in ISO 3864-1, is about 1 metre of viewing distance for every 25 mm of sign height (the shorter side). Use it with your own risk assessment.
| Size | Readable from up to about |
|---|---|
| A3 landscape (420 × 297 mm) | 12 m |
| A2 landscape (594 × 420 mm) | 17 m |
| A1 landscape (841 × 594 mm) | 24 m |
Well lit or internally lit signs can be read from further away; dim areas need larger signs.

Questions
Buyer questions about this product, answered. Can't see yours? Ask below and our team will reply.
What sizes does the No Unauthorised Entry Sign come in?
The No Unauthorised Entry Sign comes in 3 listed sizes, from A3 landscape (420 × 297 mm) at £28.97 up to A1 landscape (841 × 594 mm) at £57.10. In between: A2 landscape (594 × 420 mm). Prices are the lowest option for each size.
Which material should I choose for the No Unauthorised Entry Sign?
It depends where it goes and for how long: 3mm Dibond aluminium composite is rigid and weatherproof, the one for long-term outdoor use and busy areas. 3mm Foamex is light and smooth, best indoors or in sheltered spots. 3.5mm Correx is light and waterproof, ideal for temporary signs on fences and sites.
What artwork options are there for the No Unauthorised Entry Sign?
The Artwork choice on this page offers: "I will upload print-ready artwork" (free), "Add my text and logo to a clean layout (typesetting)" (£15), "Design it for me from my brief" (£35), "Redraw or vectorise my logo from a low-res file" (£50) and "Design a new logo for me" (£100). Design fees are fixed, show as their own line in the basket and cover the whole quantity of that item. Typesetting includes 1 proof and 2 rounds of changes; design from your brief includes 1 design and 2 rounds of changes. For the No Unauthorised Entry Sign, set your file up at the size you order, for example A3 landscape (420 × 297 mm).
What is the cheapest price for the No Unauthorised Entry Sign?
The lowest price is £28.97, which is what the calculator opens on: size A3 landscape (420 × 297 mm) and material 3.5mm Correx. Every other combination is priced as you choose it, including faster turnaround, and that price is final because we do not add VAT. UK mainland delivery is £7.95 per order and free when your goods total is £99 or more after any discount code (artwork and design fees do not count towards it).
How much is delivery for the No Unauthorised Entry Sign?
UK mainland delivery is £7.95 per order and free when your goods total is £99 or more after any discount code (artwork and design fees do not count towards it), so one sign at £28.97 on its own pays £7.95, and the charge disappears once your basket reaches £99. Mainland Scottish Highlands postcodes add £10 once per order. Northern Ireland, the Scottish islands, the Isle of Man, the Channel Islands, the Isles of Scilly and the Isle of Wight are quoted before you order.
How quickly can I get the No Unauthorised Entry Sign?
Saver is ready to dispatch in 5 working days, Standard in 3 and Express in 2, counted in working days (Monday to Friday, not bank holidays) from when your order and artwork are confirmed. The exact figure for your chosen size and options shows beside each turnaround in the calculator. Courier delivery usually takes 1 to 3 working days after dispatch, and we email the tracking details when the parcel leaves us. On the opening option, the No Unauthorised Entry Sign is ready to dispatch in 5 working days on Saver or 2 on Express.
What does the No Unauthorised Entry Sign mean?
"No Unauthorised Entry" is a prohibition sign: a red circle with a diagonal bar, meaning something must not be done. It carries the ISO 7010 P004 symbol (no thoroughfare), so people understand it even if they do not read English. The colours and shapes follow the scheme set out in the Health and Safety (Safety Signs and Signals) Regulations 1996.
How thick is the No Unauthorised Entry Sign?
The board options are 3.5mm Correx, 3mm Foamex and 3mm Dibond aluminium composite, so the board version is as thick as the figure in its name. Dibond is two thin aluminium skins with a plastic core, so it is rigid but still easy to fix. Foamex is a light foamed PVC board.
Will the No Unauthorised Entry Sign show up at night?
Only where there is light on it. We print on 3.5mm Correx, 3mm Foamex and 3mm Dibond aluminium composite, which are not reflective or glow in the dark. For car parks, yards and routes used after dark, position signs under existing lighting, or light them. Where your risk assessment calls for reflective or photoluminescent signs, you will need a specialist supplier.
Can the No Unauthorised Entry Sign be used outside?
Yes, in the right material. Dibond is the best choice for signs that stay outside long term. Correx is weatherproof and fine outside for temporary use. Foamex copes with sheltered outdoor spots but is happiest indoors. All printed signs fade slowly in strong sun over time; check them as part of your routine and replace any that are hard to read. The No Unauthorised Entry Sign is printed on 3.5mm Correx, 3mm Foamex and 3mm Dibond aluminium composite.
How do I fix the No Unauthorised Entry Sign to a wall or fence?
Foamex and Dibond boards can be screwed to a wall through holes drilled near the corners; use washers and do not overtighten, especially on Foamex. On smooth indoor walls and doors, double-sided foam tape or adhesive pads avoid drilling. Correx is best cable tied to fencing or fixed to posts. The No Unauthorised Entry Sign is printed on 3.5mm Correx, 3mm Foamex and 3mm Dibond aluminium composite.
What resolution does my artwork need for this sign?
For items read close up, aim for 300 dpi at the finished size. At 300 dpi an A1 landscape (841 × 594 mm) design needs about 9,933 × 7,016 pixels. Logos and text are best as vector artwork, which stays sharp at any size. Photos taken from websites or social media are usually far too small; our file check flags images that may print soft.
Which file types do you accept for the No Unauthorised Entry Sign?
A PDF at the finished size is best, with fonts embedded or converted to outlines. We also take AI, EPS and SVG, and high resolution JPG, PNG or TIFF files. Word, PowerPoint and Canva files are fine as a starting point, but export a full-quality PDF if you can. You can upload up to 3 files of 25 MB each on the product page, or upload later: we email you after you order. For the No Unauthorised Entry Sign, set your file up at the size you order, for example A3 landscape (420 × 297 mm).
What happens if my file is not good enough to print?
Our file check catches the usual problems: the wrong size, no bleed, low resolution images and text too close to the edge. We tell you what needs fixing before anything is printed, and you can send a new file. If you would rather we sort it, the typesetting option (£15, 1 proof and 2 rounds of changes) sets your text and logo on a clean layout. The No Unauthorised Entry Sign is printed on 3.5mm Correx, 3mm Foamex and 3mm Dibond aluminium composite.
Can my designer send the file straight to you?
Yes. You can upload your file on the product page, or place the order and upload later: we email you after you order. Your designer can send the file to us by email or WhatsApp with your order number, so it does not have to come through you. The turnaround clock starts once your order and artwork are confirmed, so send the file early if you have a deadline. For the No Unauthorised Entry Sign, set your file up at the size you order, for example A3 landscape (420 × 297 mm).
Do you check my file before printing?
Yes. A person from our team checks every uploaded file for size, bleed and resolution, and tells you if something needs fixing before anything is made. We print what you supply, so check spelling, phone numbers and dates yourself too. Production starts once your order and artwork are confirmed. The No Unauthorised Entry Sign comes in 3 listed sizes, from A3 landscape (420 × 297 mm) to A1 landscape (841 × 594 mm).
Will the price change at checkout?
Only delivery is added. The goods price you see in the calculator is final, with no VAT added. UK mainland delivery is £7.95 per order and free when your goods total is £99 or more after any discount code (artwork and design fees do not count towards it). Any artwork or design fee you choose shows as its own line in the basket, so you can see exactly what you are paying for. The No Unauthorised Entry Sign is printed in our Manchester workshop or by our UK production partner, depending on the size and material.
How much is an A2 landscape (594 × 420 mm) sign?
A A2 landscape (594 × 420 mm) sign starts at £38.33 on the lowest priced options and Saver turnaround. Pick that size in the calculator to see the price with your own material, finishing and turnaround. By material: 3.5mm Correx £38.33, 3mm Foamex £45.17 and 3mm Dibond aluminium composite £64.39. UK mainland delivery is £7.95, free once your basket reaches £99.
How do I order several of this sign?
The price shown is for one sign in the size and material you pick. Set the quantity box next to Add to basket and the basket multiplies it. If you need several different sizes or materials, add each one to the basket separately. One artwork fee covers the whole quantity of a line, and "Same artwork as another item in my basket" adds no second fee. For large runs, ask for a quote. The No Unauthorised Entry Sign comes in 3 listed sizes, from A3 landscape (420 × 297 mm) to A1 landscape (841 × 594 mm).
Can you deliver to Northern Ireland, the Highlands or the islands?
Yes, with a difference in price. Mainland Scottish Highlands postcodes, for example around Inverness, Fort William, Oban and Thurso, pay the mainland rate plus £10 once per order, even when the order qualifies for free delivery. Northern Ireland, the Scottish islands, the Isle of Man, the Channel Islands, the Isles of Scilly and the Isle of Wight are quoted before you order: use Get a quote or call 0161 315 1151. We do not deliver outside the UK. The No Unauthorised Entry Sign starts at £28.97 before delivery.
I have a deadline. Is there a faster option for this sign?
Yes. Express makes this sign ready to dispatch in 2 working days on the opening option, priced at £38.64 against £28.97 on Saver (5 days). To plan back from a date, add 1 to 3 working days for the courier after dispatch and allow for artwork: production starts once your order and artwork are confirmed. If the date is very tight, call 0161 315 1151 before you order.
How do the material prices compare on the No Unauthorised Entry Sign?
At A3 landscape (420 × 297 mm): 3.5mm Correx £28.97, 3mm Foamex £34.56 and 3mm Dibond aluminium composite £50.09. The gap stays similar on bigger sizes, which the Prices by size table on this page shows in full. Choose on where the sign goes rather than price alone: the cheapest material is not always the one that lasts in that spot.
What other signs go with the No Unauthorised Entry Sign?
Signs that are often needed alongside it include No Unauthorised Access Sign, Keep Out Sign, Caution Dangerous Site Keep Out Sign and Warning Fragile Roof Crawling Boards Must Be Used Sign. Each has its own page with sizes, materials and live prices, and ordering them in the same material keeps a set looking consistent. Add them to one basket: delivery is charged once, and it is free once the goods total reaches £99. The No Unauthorised Entry Sign is part of our Builders & Construction range.
I am one of the builders and contractors. Would I use this sign?
Use this sign where you need to say "No Unauthorised Entry" clearly. It is part of our Builders & Construction range, which gathers what builders and contractors order for building sites. Other items in the same range include Scaffold Banners, Correx Boards, Printed Hoarding Boards and Caution Fragile Roof Sign. You can mix items in one basket, and delivery is free once the goods total reaches £99. The No Unauthorised Entry Sign is part of our Builders & Construction range.
Is the No Unauthorised Entry Sign portrait or landscape?
This design is landscape, in A3 landscape (420 × 297 mm), A2 landscape (594 × 420 mm) and A1 landscape (841 × 594 mm). Landscape suits wide spaces such as fences, above doors and along corridors. If you need the other way round, choose a design option and we will lay it out for you.
Will this sign bend or bow in the sun?
Foamex is a foamed plastic, so in strong sun and heat a large, thin board can bow, especially if it is only fixed at the corners. Dibond has aluminium skins and stays flat, which is why it is the choice for long-term outdoor signs. Fixing Foamex flat against a wall, or choosing a thicker board, keeps it straighter. The No Unauthorised Entry Sign is printed on 3.5mm Correx, 3mm Foamex and 3mm Dibond aluminium composite.
Can I trim or drill this sign myself?
Foamex and Correx cut with a sharp craft knife and a straight edge: score a few times, then snap or cut through. Dibond has aluminium skins, so it needs a fine-toothed saw and a steady hand. Drill fixing holes with an ordinary drill bit, going slowly, and keep holes at least 10 mm from the edge. Cutting into the print loses the bleed, so allow for it in the design. The No Unauthorised Entry Sign is printed on 3.5mm Correx, 3mm Foamex and 3mm Dibond aluminium composite.
Can I put the No Unauthorised Entry Sign on a door?
Yes, fixed with double-sided foam tape or screws. A 3mm Foamex board with double-sided foam tape also works well on a flat door. Place it at eye level on the push side or beside the door, where it is not hidden when the door is open. If the door is a fire door, check with whoever manages it before screwing anything into it.
Should my artwork be CMYK or RGB?
Supply CMYK where you can. RGB files are converted to CMYK for print, which can make very bright greens, blues and oranges look slightly duller. If you need a brand colour matched, give us the Pantone reference and we match it as closely as the material allows. Small differences between a screen and the printed item are normal, because screens give off light and print reflects it. For the No Unauthorised Entry Sign, set your file up at the size you order, for example A3 landscape (420 × 297 mm).
Can I have the No Unauthorised Entry Sign in another language, or in two languages?
Yes. Choose "Add my text and logo to a clean layout (typesetting)" (£15) and send the wording in each language; you get 1 proof and 2 rounds of changes. Keep the symbol and the sign colours the same so the meaning stays clear to everyone. Please send the translation yourself: we lay out the text you give us, we do not translate. The No Unauthorised Entry Sign is printed on 3.5mm Correx, 3mm Foamex and 3mm Dibond aluminium composite.
Can I return this sign if I change my mind?
No. This sign is printed to your order, and the 14-day right to cancel does not apply to goods made to your specification (Consumer Contracts Regulations 2013, regulation 28(1)(b)). You can cancel for a full refund before production starts. If an item is faulty, damaged or not what you ordered, your Consumer Rights Act 2015 rights apply and we reprint or refund. The No Unauthorised Entry Sign is printed in our Manchester workshop or by our UK production partner, depending on the size and material.
Can I reorder the same sign later?
Yes. Order the same product and options again and upload the same file. Keep your print-ready file safe so a repeat order is quick. If anything like a phone number or price has changed, update the artwork before you reorder. The No Unauthorised Entry Sign is printed in our Manchester workshop or by our UK production partner, depending on the size and material.
Can I order several different designs in one order?
Yes. Add each design to the basket as its own line with its own file or online design, then check out once. Delivery is charged once per order, and becomes free when the goods total reaches £99. If several lines use the same artwork, choose "Same artwork as another item in my basket" so you only pay one design fee. The No Unauthorised Entry Sign comes in 3 listed sizes, from A3 landscape (420 × 297 mm) to A1 landscape (841 × 594 mm).
Can I get a VAT invoice?
No. We are not VAT registered, so we do not charge VAT and cannot issue a VAT invoice. You get an order confirmation email with the items, options and total paid, which works as your receipt. Because no VAT is added, the price you see in the calculator is the price you pay for the goods, with delivery shown at checkout. The No Unauthorised Entry Sign comes in 3 listed sizes, from A3 landscape (420 × 297 mm) to A1 landscape (841 × 594 mm).
Do I need an account to order?
No. You can check out as a guest and pay by debit or credit card, processed securely by Stripe. Creating an account at checkout lets you see past orders in My Account. Either way you get an order confirmation email and a tracking email when your order is dispatched. The No Unauthorised Entry Sign is printed in our Manchester workshop or by our UK production partner, depending on the size and material.
What if I spot a mistake after I order?
Contact us straight away on 0161 315 1151 or WhatsApp with your order number. If production has not started we can take a corrected file, or cancel the order and refund you in full. Once production starts the order cannot be changed. Printing that matches the design you approved or the file you supplied is not a fault, so check spelling, phone numbers and dates carefully before you order. The No Unauthorised Entry Sign is printed in our Manchester workshop or by our UK production partner, depending on the size and material.
Can someone help me choose the right options for this sign?
Yes. Call us on 0161 315 1151 or message us on WhatsApp and tell us where the sign will go, how long it needs to last and your deadline. You can also ask a question on this page; our team answers and the question may be published to help other buyers. For a price on something the calculator does not cover, use Get a quote. The No Unauthorised Entry Sign is printed in our Manchester workshop or by our UK production partner, depending on the size and material.
How many No Unauthorised Entry signs do I need?
Walk the route people take and put a sign wherever someone needs the message and would otherwise miss it: each entrance, each approach to the hazard and each change of direction. Larger areas usually need the same sign more than once, in the size that suits each viewing distance. Add them all as one line with a quantity, or as separate lines if you need different sizes or materials. The No Unauthorised Entry Sign comes in 3 listed sizes, from A3 landscape (420 × 297 mm) to A1 landscape (841 × 594 mm).
What if my order arrives damaged?
Check it when it arrives. If anything is damaged or missing, tell us within 48 hours with photos of the item and the packaging, through the contact form or on WhatsApp, with your order number. Do not send anything back until we reply; we then arrange a reprint or a refund. This does not affect your legal rights, which the returns page explains. On the opening option, the No Unauthorised Entry Sign is ready to dispatch in 5 working days on Saver or 2 on Express.
How do I clean this sign?
Wipe with a soft cloth and warm, soapy water, then rinse and dry. Do not use solvents, scouring pads or strong cleaners, which can dull or lift the print. Store spare boards flat so they do not bow. The No Unauthorised Entry Sign is printed on 3.5mm Correx, 3mm Foamex and 3mm Dibond aluminium composite.
