I need to surface fix some plastic electrical trunking to a fairly irregular surface internal wall. Would a grab adhesive be suitable for this application or would I be better off drilling through the back and attaching using screws?

Screw fixing is always preferable on an irregular surface.
Or double-sided foam tape, if it'll be SEP by the time it needs to be removed ...

Use the self adhesive type, but also drill and fix with screws to the wall where there are gaps between wall and trunking. Fix at regular intervals anyway, the self stick never remains stuck for long.
Drill and screw, and if it's over an escape route you'll also need metal cable restraint clips inside the trunking.

Drill and screw try to aim for the high spots on the wall. If you have to screw at a point where the wall bends inward use packers behind the trunking.

The self adhesive that comes with that trunking is s*it. It falls off even a smooth surface after 3 months. Use your own glue on a smooth surface, or preferably screws. Or a mixture of both. On an irregular surface, no amount of sticky stuff will work.
In my house they seem to have used some kind of spongy double sided tape, not very good. its beginning to wobble. Brian
AKA self adhesive trunking. Very good for installing the trunking, seems to be OK for a few months but really feeds screwing/nailing in place for a permanent job. (spoken from experience!)

The only thing I'd trust the double sided tape for is to hold the trunking still while you drill and screw it.
That's what I use it for. And it fills minor irregularities...
