They are inefficient, especialy Zanusi's. Even new fridges of the same
size can have energy use stats that vary by ~100%. A crapy old Zanusi
will be much worse.

Looking at the argos website, I find an astonishing lack of variability
in the energy use.
More money just buys you a prettier box, and more stuff.
It does not give better insulation.
I approximately halved the energy use of my freezer with several slabs
of 10cm polystyrene.
This paid itself off in the first year.

It may be that better more efficient ones are available, but not in
argos.
