Can it be done? If not are there any other options to increase the security of a UPVC door?

You can get door bolts for this purpose, they are surface mounted on the inside fixed with self tappers. Chubb, Era etc do them. Why do you need to make it more secure?

If security is a real concern then I would consider a solid bar across the door - with some fixing into the brickwork of the door recess. I would not trust self tapping screws. At least the usual locks are embedded into a fairly strong channel in the extrusions.

The weakest point is your lock cylinder, a locksmith can advise you on a non pick/snap/bump/drill one.

Yeah - should have mentioned I was looking for an extra lock(s) that can be locked from the outside (i.e. when I'm not there).

When we lived in France we has a security lock fitted to our main, metal-clad door. It consisted of a lock in the centre of the door and four substantial bolts that were linked to this by flat metal bars on the inside. It took several turns of the key to fully withdraw the bolts, if you had shot them all the way out, into the walls and floor as well as the frame fittings, with the key on exit. This design meant the door was secured by the bolts along all four edges and, when fully actuated, didn't rely on the strength of the wooden door-frame. Our insurance company insisted on one after our original fitting succumbed to an attack from someting like those "master keys" used by the Police.
Needless to say a quick Google for a "French door lock" doesn't produce the right results. I think you will need to look at *.fr sites. We got ours from a locksmith on our town.
You could try a more DIY solution using solenoids at vulnerable points with a common electronic key to withdraw them. However, search for "Ring of the Devil" to make sure you aren't installing a compromised design.
