How often should you replace safety signs?

"How often do we need to replace these?" is one of the most useful questions a customer can ask before they buy. The honest answer depends on the material and the environment, but here are the realistic numbers from our customer base.

By material

• Self-adhesive vinyl indoor — 5-7 years. Limiting factor: adhesive degradation, surface UV fade.
• Self-adhesive vinyl outdoor — 3-5 years. Limiting factor: UV fade, weathering of overlaminate.
• Rigid PVC (Foamex) indoor — 7-10 years. Stable indoors, limiting factor is graphic fade.
• Rigid PVC outdoor — 5-7 years. UV-degrades the substrate over time.
• Aluminium composite (Dibond) outdoor — 7-10 years for screen-printed, 10-15 years for engraved or pressed-aluminium.
• Powder-coated steel monolith — 15+ years before refurbishment. Internal LED and graphics may need refresh sooner.
• Photoluminescent signs — 10+ years for the photoluminescent pigment, but substrate/laminate may limit total to 7-10 years.
• Engraved aluminium / Traffolyte — 15+ years. Effectively permanent for normal indoor use.

By environment

• Direct UV — south-facing external signage degrades 30-50% faster than north or shaded
• Wash-down / cleaning chemicals — kitchens, food processing, healthcare deep-clean environments degrade laminates over time
• Touch frequency — door push-points, lift call buttons, frequently-handled signs wear faster
• Vandalism and graffiti — even with anti-graffiti laminate, repeated cleaning shortens life
• Salt air — coastal locations corrode standard finishes; aluminium and stainless preferred

Signs that need replacing now

• Faded to the point where the pictogram or wording is unclear
• Cracked, peeling, or delaminating substrate
• Tape repairs (if you've taped it, you're replacing it)
• Outdated regulatory wording (e.g. pre-2013 BS 5499-1 fire exit pictograms — replace with BS EN ISO 7010)
• Wrong language for the site population (multi-language sites with English-only signs)

Practical refresh strategies

For estate-wide signage, plan a phased refresh aligned with refurbishment cycles. Most facilities adopt a 7-year refresh cycle for high-volume safety signage and a 15-year cycle for monoliths and architectural identification.

Our sustainability page covers our take-back recycling scheme — when you order replacement signage from us, we accept the old signs back free of charge for material recycling.
