Got an external uPVC double glazing unit which has a knackered seal. I'm
going to change it myself but it will be the first time I've done such a
thing. Can anyone offer any tips with regards to releasing the old glazed
unit from the grip of the security tape?

It's double sided foam tape, cut the bond using a sharp but flexible
knife next to the glass.

If you have two people, push a piece of thin strong wire through
(a cheese wire), and then with one person inside and one outside
holding each end, cut through the foam tape with the cheese wire.
Watch for the window falling out. The cheesewire will probably
knacker the double glazing unit seal, but yours is already, so that
doesn't matter. Don't use a rough cutting wire or you might shatter
a toughened glass pane and/or mark the uPVC.

When you lift the unit out, be very careful not to ding the corners
(particularly against masonary/concrete), as that easily shatters
toughened glass, particularly with large windows where you don't
get a second chance if you do.

You'll need to clean the remaining window tape off the uPVC frame.
