In a landscape where building safety, compliance, and fire protection standards are evolving fast, The Safety Letterbox Company continues to lead with solutions that don’t just meet regulations—they redefine them.

Secure Information Boxes (SIBs): Compliance Has a New Standard
The term Secure Information Box (SIB) has now fully replaced all legacy terminology, including Premises Information Box (PIB) and “big red fire box,” across all major regulations and Codes of Practice.

If your documentation, signage, or products still use outdated terminology, they are no longer compliant.

At The Safety Letterbox Company, we manufacture the only fully Secured by Design certified SIB made entirely in the UK, tested as a complete unit to STS205 BR2.

No exceptions. No compromises.
• Full third party certification covering box and lock
• Compliance with all regulated SIB signage requirements
• Purpose built to secure the critical building information emergency services rely on

“At SLB, compliance is not optional. Precision, certification, and rigorous testing are built into every product we supply. Safety is never negotiable.”
— Alison Orrells, CEO
When lives depend on access to accurate information, compromise is not an option.

2-Hour Fire Rated Mail & Parcel Boxes: The Gold Standard in Compartmentation
Since 2002, we have led the UK market in fire rated mail and parcel systems—and remain the only UK manufacturer offering a fully tested, independently certified 2 hour fire rated solution.
Our commitment is simple:
• Design out risk
• Build in safety
• Deliver solutions that never compromise

In buildings where compartmentation protects residents and assets, mail and parcel boxes are not just an aesthetic choice - they are a critical fire protection measure.
Our 2 hour fire rated range is trusted by developers, housing providers, and fire safety professionals who refuse to settle for “good enough.”
