It also appears that $local_part gets set in the MAIL ACL. As an example
with exim -bvs toby-exim@???:
... and I can confirm that this works with testing and that the
local_part and domain are both set at the mail acl even though I am not
doing call outs.
However, I am 99% sure that this won't work when I have to move (as I
may well haev to do) the sender verification into the RCPT ACL so thank
you for bringing that to my attention, I believe I can use
$sender_address in this case anyway.

Absolutely! Here are the -d+all logs for an SMTP session with sender
verification:
14:17:22 4208 SMTP<< MAIL FROM:<toby-exim@???>
14:17:22 4208 using ACL "acl_check_mail"
14:17:22 4208 processing "require"
14:17:22 4208 check verify = sender
