Planning to have timber doors made for a new extension (2 sets of french doors with a fixed panel between - as well as a set of windows).

what type of locking system should I be looking for to make sure that the doors are secure and that they meet insurance guides?

Expect that the multi-point system thats typically on uPVC doors would work, but just wondering if there is some other system?

most insurance companies require a lock conforming to BS3621 to be fitted to the 1st opening door and key operated lockable bolts top and bottom on the "fixed" leaf,obviously these doors are going to be rebated and this throws up a grey area as rebate kits are not kitemarked because the locks conforming to BS3621 are not tested with these on.
multipoint locks are a good option but do not confirm to a BS standard as of yet but i believe a rating of some sort is being finalised,id check with a few insurance companies if its a worry

normal procedure seems to be to put lever action or spline key bolts top and bottom on the "slave" leaf (1st one to close) and mortice lock on the "master" leaf.

I've just done a pair with lever action bolts (aka finger bolts) on the slave and a 5-point (well 7 if you count the rollers) lock on the master.
I grooved the edge of the master for the multipoint lock with 16 and 12mm router cutters but regret not doing it with this special "eurogroove" cutter


as it was a bit time consuming and the result wasn't perfect. Bought the multipoint lock from a local supplier with shoot bolts top and bottom, about £70 i think.

don't have anything to do with this lot http://www.directlocks.co.uk/ they have a bad reputation

Didn't rebate the door edges but left them 5mm apart (on the inside) and put in a aquamac 21 flipper weatherseal.
