It doesn't have to be rated for in wall use - mains cables that carry much more power do (to take account of them heating up).

Amp/receiver most likely will be located on a low hifi rack, about half way along the inner wall (wall about 2.7m). Below a window.
Not ideal location, but it will be what I have to work with.
Ideally, will run speaker cable horizontally and if possible, kept well away from new power cables.
Thanks
