Frequently Asked Questions
What are construction site warning signs used for?
These signs are used to alert staff, contractors and site visitors of potential hazards on site. They help demonstrate regulatory compliance and minimise unnecessary accidents.
Are construction warning signs a legal requirement in the UK?
Absolutely. The Health and Safety (Safety Signs and Signals) Regulations 1996 require UK construction businesses to display construction safety warning signs wherever there are site hazards present. Failure to do so opens your business up to serious legal risks.
Where should I place these signs on site?
Ideally, these signs should be displayed near high-risk hazards such as scaffolded structures, excavation zones, heavy machinery and other hazards that pose a serious risk to life.
Do your signs comply with UK safety standards?
100%. All our construction safety warning signs adhere to BS EN ISO 7010 standards, ensuring the appropriate use of recognised symbols, colours, and layouts for maximum clarity.
Can I get custom construction safety warning signs?
Of course you can. Any of our custom safety warning construction signs can be custom printed with your site name, logo or whatever other design elements you require.
What materials are your construction warning signs made from?
We offer a wide variety of signage materials, including Self-Adhesive Vinyl, Viprint (Rigid Plastic), PVC Foamex and Aluminium Composite (Dibond). This variety of materials caters for all budgets and application requirements.
Are these signs suitable for outdoor building sites?
If you need a durable sign that can withstand the tough British weather, we recommend opting for our PVC Foamex or Aluminium Dibond boards. Both these options offer long-term resistance against wind, rain and UV.
Do you offer bulk discounts for site-wide signage?
For sure. We operate a quantity-based pricing structure for our safety warning construction signs, which allows you to benefit from better pricing the more you order. We won’t be beaten on price and offer a price match guarantee to back up this claim!
