Wooden doors can have multi-point locks. However, the Police
recommendation
is two BS thief resistant mortise locks, one at 1/3 and one at 2/3 of the
door height. All external doors should also be hung on three metal
hinges,
not less than 100mm long.

So the police don't recommend multipoint locking wooden doors? (by
multipoint, I mean operated from one handle & key)

BS 3621 thief-resistant locks will have protection against drilling, bolts
that are resistant to hacksaws and will be resistant to being picked. While
there may be multi-point locks that offer equivalent protection, there is no
provision in BS 3621 for them, so there is no easy way to tell which they
are. That is why the Police do not recommend them. However, your insurers
may accept a multi-point lock as being a suitable alternative to a BS 3621
lock.
