I think what you are saying is the same as what I suggested. I never
suggested wiring them as spurs, but did suggest using a sunken junction
box, whereas you suggested chocolate block. Is there any reason to use
chocolate block over a junction box apart from the hassle of chiselling
brick to sink it in?

Is a chocolate block in a dry-lined wall regs-compliant? Seems crazt
if so as the metal terminals are "on show".
