I think a website update might be required on the Met police website: content.met.police.uk/Article/Front-door/1400012029686/1400012029686 UPVC/PVCU front doors are generally unsuitable for retro-fit security devices. Not only is the material not strong enough to support devices fitted with steel screws unless secured into the internal metal framework, but such changes to the original design may invalidate an existing warranty or possibly damage the integral locking assembly. If in doubt, consult the installer/manufacturer. Modern designs will usually incorporate deadlock shoot bolts or a multi-point locking system, both throwing a number of bolts from the door into the frame. Under these circumstances there will not normally be any need for additional devices.
