I want to fix something to the external "fence" which is in fact stacked
concrete gravel board, painted with external paint.

At the moment I have stick on cable tie fixings on plastic, and drill and
push in fixings in brick.

I am reluctant to drill into the concrete because of the chances of
hitting aggregate, cracking away the surface, or hitting reinforcing steel.

Is there any reliable surface fixing? I suspect that little will stick to
concrete covered with external paint.

Cheers

can you not push in a long cable tie between a pair of concrete boards,
loop round a post and then back through between an adjacent set of
gravel boards and then form a loop?

If you stay away from the edges your chance of hitting rebar are quite
small. I have drilled into both concrete posts and gravel boards without
problems such as surface cracking. If you are just fixing to the gravel
boards then I would drill a test hole, if that hits rebar drill elsewhere.
Once you have established the position of one good hole you should be able
to take a measurement for all the rest as the rebar position will most
likely be the same for all the gravel boards.

Would the gap between two adjacent gravel boards hold the mounting part
of a (stainless steel) P clip?

Or make your own p-type clip from builders band

You could trap a longer length of metal between two of the gravel boards

Then remove the paint with something.
Any polyester/epoxy style glue is pretty good on concrete
I even used car body fuller to reglue weights on a nylon washer drum.
They worked until other reasons caused its scrappage

Id attack the surface with paint stripper and a wire brush, attach using
CBF and then repaint

And in fact for reaosnable stresses hot glue is also possible

Have you tested it, using a metal detector?

I assume that you are fixing to the normal, slotted posts? If so, these
may be overkill, but they are an option.

If you do go down this route just be aware they come in two sizes, 4"x
4" and 4" x 5"

Covering several suggestions - gravel boards are pretty heavy and I need
to be a couple of boards down so lifting (and keeping lifted) the boards
could take a lot of strength and effort.

They were fitted over 10 years ago by a pair of muscular builders.

10 years on I don't fancy my chances of moving them, although wedges and
levers might help.

I had discounted using the gaps for this reason.

The rest of the fence run using wood makes fixing a doddle.

Drill in the crack between the boards, insert a nylon wall/raw plug and
when it expands when screwing into it the weight of the gravel boards
will hold it firmly in place.

What size cable? If small you can get pin plugs that will take the clips
that use a nail for fixing.

I would then look at a previous post that suggested
the postfix fittings

https://postfixbrackets.co.uk/

https://www.amazon.co.uk/s?i=merchant-items&me=A2FP9BRVOKT6XH

just make sure that you get the correct size for your posts

https://www.youtube.com/watch?v=KDaS2XpaDpA

I've used them in the past to hold back plants against a fence using
gantry wire. Using something like the components shown in this link

https://www.screwfix.com/p/greenbrook-catenary-wire-kit-3mm-x-30m/971hv

the wire can be pulled tight and easily span multiple fence panels
