You can chase out a party wall for electric cables so what you need to

Unfortunately the party wall is only one brick thick, so really I'm limited to screwing something into the wall such as a bracket


Are you going to mount your speakers on this wall ? :-)

If this wall is back-to-brick, then before you mess about with
handrails, consider overlaying it with Green sound-block
plasterboard, possibly with some acoustic insulation behind it,
or is this rental property ?.
