I'm not sure what metal exactly, but a magnet sticks to it.

Although the door structure is metal the complete side edge section,
where the lock protudes, is a wooden insert. Presumably there is also
some insulation inside the door.

The lock is stamped ERA, and looks identical to the 5 lever deadlock
shown on their website he http://www.era-security.com/Mortice.html

There are door handles on both sides, as shown. For slightly better
security, there are also top & bottom rack bolts and a door chain.

There are no hinge bolts, or London/Birmingham bars fitted, and it
opens inwards.

The one advantage with this arrangement is that it is impossible for
me to accidentally lock myself out. The main disadvantage is that
during the day, when the front door is unlocked, anybody can simply
open the front door and walk in!

Is there a simple method for me to solve this disadvantage and
possibly improve the security of the door?

David,

Is this the sort of door that you have?

Yes, that's very similar to the one I have. Possibly the same. The
developer would have bought scores of them in 1996/7.

I'm not too sure how I would go about fitting an additional lock into
a metal door. Is it still a chippies job?

I thought about removing the external handle, and fitting some sort of
blank end, but I'm not sure that they exist.
