When shopping for a new front door, you will often see the “Secured by Design” (SBD) logo. This isn’t just marketing jargon; it’s a mark of high security that gives you genuine peace of mind. This guide explains what it means and why it’s important for protecting your home.
What is “Secured by Design”?
Secured by Design is an official security initiative created and run by the UK Police. Its goal is to “design out crime” by promoting building products that are proven to be highly resistant to attack.
When a door is SBD accredited, it has achieved the “Police Preferred Specification.” This means it has been independently tested to a rigorous standard and is recognised by the police for its ability to deter and prevent break-ins.
How Does a Door Earn SBD Accreditation?
A door can’t simply be given SBD status. It must first pass a tough, independent physical security test known as PAS 24.
The PAS 24 test simulates a real-world attack on the door by a burglar. Independent testers use common tools like crowbars, screwdrivers, and chisels to try and force entry. They attack the locks, hinges, and panels to ensure the entire doorset can withstand a sustained assault.
Only after a door has passed PAS 24 testing can it be considered for the Secured by Design accreditation. SBD may also require additional specifications, such as the use of laminated security glass, to achieve its standard.
What’s the Difference Between SBD and PAS 24?
It’s easy to confuse the two, but the difference is simple:
- PAS 24 is the physical security test. It proves a door can physically resist forced entry.
- Secured by Design is the police accreditation scheme. It uses the PAS 24 test as a minimum requirement.
Think of it this way: passing the PAS 24 test is a crucial step, but achieving the SBD accreditation is the official police seal of approval.
Why SBD Certification Matters to You
Choosing a Secured by Design door gives you confidence that you are buying a genuinely secure product. However, it’s important to know that the certification applies to the exact specification of the door that was tested.
If you change the configuration – for example, by adding a letterplate or choosing a different type of glass, it may no longer meet the SBD standard.
Always ask your installer to confirm that the specific door you are ordering is fully SBD compliant.
