Enhanced security performance (PAS 24) and Secured by Design

Only certain windows, doorsets and locks which meet high standards for security are accepted by the Police security initiative Secured by Design (SBD). We can help you meet SBD requirements, with certification via a BSI Kitemark.

Secured by Design (SBD) means domestic windows and residential doors meet the high standards for security as accepted by the Police.  They have to be stringently tested  to meet PAS 24, the specification for Enhanced security performance requirements before they are awarded a certificate by an independent UKAS accredited certification body, such as BSI, which is then approved by Secured by Design. 

The SBD document requires that all windows and door assemblies are covered by a BSI Kitemark or equivalent certification to PAS 24 for domestic windows and for residential doors.

Windows and doorsets are tested by replicating the forces that would be applied by an intruder.  All hardware and potential access points on the window are tested.  The test for enhanced security is purely against intruder attack rather than a test of an individual hardware component and includes:

  • Manipulation of hardware
  • Assessment of glazing security
  • Mechanical loading test
  • Manual check test
