I'm about to install some PVCU (plastic) French doors from Wickes and
I'm not sure about how to go about installing the frame anchors.

The anchors are 8mm diameter so I need to make an 8mm hole through the
door frame to accommodate them. The problem is that the hole will go
through the steel frame inside the plastic frame as well and I'm not
sure whether I should start with an 8mm HSS bit and just try to make
the hole in one go, or would it be better to use a pilot HSS bit of
smaller diameter first to stop the larger 8mm bit wandering?

Bosch multimaterial bit straight through the lot works quite well IME.
(it may not be long enough to drill the full depth in the masonry - but
it will serve to start the hole off if nothing else.

Anyone have any experience of doing this? What should I do?

Use packers to keep everything square, keep testing as you tighten
things up. Once its all sat square you can foam it in place. You don't
need that many frame anchors in total - say three per side and depending
on width one or two along top and possibly bottom.

Remember the opening bits derive much of their rigidity from the way the
glass is fitted. You want the plastic packers to brace the glass in the
rebate so that it acts like a restraint to the door drooping.
