Secured By Design (SBD) was first established in 1989 and is made of a group of national police projects which focus on the design and security for new and refurbished homes. The body supports the principles of ‘designing out crime’ through physical security and processes.

Working with the industry and test houses, Secured By Design helps create high level security standards – responding to trends in crime. This scheme has proven to be successful in reducing the risk of crime as well as the fear of crime.

Secured By Design Accreditation

The Secured By Design member company status is awarded to double glazing companies that pass standards and tests nominated by the police service. These standards and related tests must demonstrate the product’s effectiveness in preventing or reducing crime ( this is usually by resistance to physical attack.)

Many companies in the window and door industry strive to have their products designed to meet the SBD standard. Only a Secured By Design accredited installer will be granted permission to use the Secured By Design logo on their products.

You can find out more about the Secured By Design Test Standards on their website.

Window and Door Security

The security of your home is incredibly important and the first step to securing your property is through high security windows and doors. Why is window and door security so important? Your windows and doors act as the main point of entry and as a result, are often a target of burglary. As a home owner, it is your responsibility to ensure your windows are well protected against any security risks.

Thinking of improving the security of your home? Here are some Secured By Design tips:

  • It is better to buy a new “door set” which includes the complete assembled frame and door – all certified to British Standard PAS 24-1 ‘Doors of Enhanced Security.
  • Make sure new windows are certified to British Standard BS7950 “Windows of Enhanced Security” or PAS 24:2012.
  • Make sure you replace any weak or rotten windows and doors.
  • Door hinges must be sturdy and secured with strong, long screws. Security fit hinge bolts and security hinges will help reinforce the hinge side of a door against force entry and help protect the hinge.
  • A uPVC or composite door should be fitted with a multi-point lock which meets BS 3621 standards.
  • For extra door protection, consider fitting a cage or restrictor to your letterbox. This prevents thieves from gaining inside access.
  • An external letterbox should be tested to TS009:2012 which covers free standing or surface mounted letterboxes.
  • A door viewer will help you identify people before opening the door.
  • Door chains can prevent people pushing their way in but must be securely fixed.
