Dwelling Security

Is Secured By Design and PAS 24 the same thing?


When it comes to PAS24, there is a frequent misunderstanding that it is Secured By Design (SBD).



Though they both test and certify that products adhere to their thorough security standards, PAS24 and Secured by Design have different standards.

Concerning Secured By Design (SDB)


This is a police initiative that aims to persuade the construction sector to incorporate crime prevention measures into the planning of developments to help decrease the likelihood of crime and people's fear of it.


The National Police Chiefs' Council (NPCC) owns Secured by Design, which is backed by the Home Office Crime Reduction and Community Safety Group and other government agencies. The Secured by Design programme has the support and endorsement of the National Police Chiefs' Council for England, Wales, and Police Scotland.



How does PAS 24 security work, then?


The enhanced security standard, known as Product Assessment Specification (PAS)24, outlines the performance and test requirements for enhanced security windows and doorsets. The original standard (PAS 011) has undergone numerous revisions since it was first published in 1994, including BS 7950.



What distinguishes Secured by Design from PAS 24?


A) Secured by Design (SBD) is the official police security programme that aims to increase the security of structures and the areas around them so that people can live, work, shop, and visit in peace. The actual security testing for windows and doors is done according to PAS 24.

Why is this important?


Project developers and actual end users can feel confident in the windows and doors in their homes thanks to the compliance tests recommended by these standards and the related guidance.


It will be possible to manufacture and install a product that is reliable, secure, safe, and weathertight with the help of this testing and certification.


Any new residential windows and doors must be tested to PAS 24 or a suitable alternative, according to Approved Document Q, which supports the building regulations, in order to help ensure adequate security.

I must emphasise that SBD is not a procedure for testing products or a test standard.

SBD has authorised a small number of organisations to offer testing and third-party certification in accordance with the demands of the initiative.


SBD was established in 1989 and is credited with significantly lowering burglaries and break-ins.


SBD-compliant windows and doors are one of the first lines of defence against unauthorised entry. They can aid homeowners in enhancing security while also lowering the cost of their home insurance.


Some of these requirements include the PAS 24 and BS 6375-1, 2 and 3 tests of window and door products as well as the fabricator/manufacturer certification, which includes initial and ongoing site audits to evaluate the effectiveness of the factory's product control systems.


What role does Part Q play in this?


Well, to begin with of course, Part Q (Dwellings) only applies to newly constructed homes. However, in fairness, why would you not replace your doors and windows to meet the minimum standards outlined in Part Q1, which states that "Q1 Reasonable provision must be made to resist unauthorised access to –

(a) any dwelling; and

(b) any part of a building from which access can be gained to a flat within the building"?



Well, the approved document does cite PAS 24 for doors and windows as well as other favourable references (see excerpts below):
