Brill, thanks for clarifying that.
OMG, did anyone ever do that (rhetorical :-).
I've see the different eras of power provision as I've tidied up my place:
Tiny round 2 pin surface mounted sockets mounted on the dado rail by the fireplace (thankfully not operational).
Single 13A sockets in the skirting with beefy recessed thermoplastic back boxes, a bit current PB back boxes but chunkier.
Twin 13A sockets in skirting with recessed metal backboxes heavy enough to have been shipyard built.
No evidence of the intermediate 5 & 15A stuff though.
