Interesting info. I wasn't aware that PVC-u doors aren't fitted with BS3621 locks. Personally, I hate PVC doors, especially white. I had hardwood doors fitted instead, with BS3621 locks and deadbolts.
I repeat more or less what I said in an earlier posting - whatever precautions you take, a professional thief can be in and out of your property within 5 minutes, together with your most valuable possessions, so make sure that you conform to your insurance company requirements for the resulting claim. And remember that you're not allowed to shoot the thieves, but I think they're allowed to shoot you if you offer resistance, and then probably sue you for stress!
