Have just been drilling into a dividing wall in a 1936 terraced house in
London, to hang up a cupboard in the bedroom.

What I'm drilling into is almost like soft sand. I guess it must be some
kind of breeze block mortar that has deteriorated? The only thoughts I have
is to pack some polyfilla around the rawlplug to fill in the hole and get
some grip. Is that a good idea? Novice appreciates any advice on what best
to do. thanks.

Interesting questions. As Churchill said, the U.S. and the U.K. are "two
nations divided by a common language."

So help this American understand what you're talking about, please.
What is a breeze block? What is a rawlplug? What is polyfilla?

Breeze block is a sort of low density brick block made of coal power
station slag..sometimes called a cinder block. A rwawlplug is a trade
name for originally a fiber plug inserted into masonry to take a wood
screw. Now universally plastic.

Polyfilla is a trade name for (iriginally) a cellulose based
filler..somewhat like 'spackle' ..its now a tradename for a huge variety
of filling products..
