Secured By Design
What is Secured By Design?
Secured By Design (SBD) is an official police initiative founded in 1989 to “design out crime” through high-quality products and smarter building standards. Backed by the UK Police Service, it works with manufacturers, architects, and developers to ensure homes and commercial buildings are built with security in mind.
The initiative is built on one key goal, which is to reduce opportunities for crime. It achieves this by recognising and promoting products that meet the Police Preferred Specification, a benchmark that ensures exceptional resistance to forced entry and tampering.
Why choose Secured By Design windows and doors?
Choosing SBD-accredited products means investing in long-term quality and peace of mind, offering:
- Proven protection against forced entry and intrusion.
- Recognition from insurers and local authorities.
- Compliance with building and planning specifications.
- Increased property value and buyer appeal.
- Yearly product testing for consistent reliability.
- Enhanced performance without compromising aesthetics.
How Nine Zero meets all SBD standards
We must subject our products to intensive testing, simulating real-world break-in attempts using sophisticated tools and methods. Windows and doors are tested for resistance to impact, levering, and forced entry, alongside long-term performance metrics such as durability, stability, and material strength.
But earning the accreditation once isn’t enough. Maintaining it demands ongoing excellence.
Our products and maintaining SBD accreditation
To continuously achieve the correct standard, we undergo a detailed yearly audit and re-certification process. This involves working closely with independent testing bodies and submitting each product for rigorous examination to verify its performance. This ensures consistent excellence across all materials, fittings, and finishes. It also means our customers may rest assured that all products offer the same levels of security.
Our designs combine traditional craftsmanship with modern security innovation, incorporating multi-point locking systems, reinforced frames, and high-performance glazing. All without compromising the timeless elegance of timber.
