Hi Dan, Due to the nature of the walls in old Victorian homes you need to drill in to the bricks not the plaster, if this still isn't possible you will need to inject a 2 part solvent Glue then apply a bolt which you can then fix too. Theses old hose are fragile, even plaster won' hold it , maybe cement but that still need something to stick to and if the surface is dry and dusty then cement will just fall out. Hope this helps.
