The external pipe should be 32mm to prevent freezing. And external
insulation where necessary. All in regs. It should also be in the makers
instructions.

A number of Worcester Bosch models require 21mm* plastic pipe for the
condenser drain, there is nothing in the installations instructions
about terminating it to 32mm (are such adaptors even available?)

Yes 21mm, bloody funny size but available from the sheds, but not from
BES.
