Secured by Design (SBD) operates an accreditation scheme on behalf of the UK police for products or services that have met recognised security standards. Such products or services must be capable of deterring or preventing crime and are known as being of a ‘Police Preferred Specification’.

Police Preferred Specification ensures that products have not only been independently tested to a relevant security standard, but also are fully certified by an independent third-party certification body accredited by the United Kingdom Accreditation Service (UKAS). A full list of UKAS bodies can be found within the Testing and Certification sections of this website.

Alternatively, an approved body such as the LPCB, Sold Secure or Thatcham can also provide acceptable levels of testing and certification for the purpose of our scheme. Police Preferred Specification also requires regular re-testing and inspection of the manufacturing facility (again by a UKAS body) to ensure that the quality and performance of production remains at the highest levels. Such inspections usually take place on at least an annual basis.

There are a wide range of security standards throughout the world, from a variety of sources for all manner of products. Listed below are the most commonly used ones here in the UK and those most likely to be requested by specifiers and Designing Out Crime Officers (DOCOs). Please be aware that the list is not exhaustive and that from time to time additional or alternative security standards may be stipulated for specific crime risks.

Please contact SBD or your local DOCO if you can't find what you are looking for and need assistance.



Technical standards

These are an essential part of selecting the correct security. To assist with the comparison of standards where different risk levels apply, we have published the following guides in conjunction with the British Security Industry Association (BSIA) and the Loss Prevention Certification Board (LPCB):

Standards - Computer Security
Standards - Security Screens
Standards - Interpretive Document for BSEN 1627 to 1630

To purchase BSI Standards

Security products without the benefit of a suitable public test standard may be accepted having passed our evaluation based on research by a technical authority acceptable to Secured by Design e.g. Forensic services, Home Office Centre for Applied Science & Technology (HOCAST) or Motor Insurance Repair Research Centre and Thatcham.

Sold Secure
