I may have the opportunity to purchase some good condition used
double-glazed PCVu french doors. They are 5 years old. Will I have
problems with the building regs if I use them in a new extension ? What
if I can't prove what they are filled with etc.?

I'd be surprised if the frames weren't date-stamped somewhere
(everywhere?) which would provide evidence for the BCO - although didn't
the regs change about 5 years ago? Which may be worse for your case...!
