Paul,
The '76 Regs only "advised", as to how many socket-outlets should be installed, it reads
something like this:
Kitchen 6
Living Area 2
Bedrooms 2(each)
Laundry 1
Clock 1
Please bear in mind, that when these Regs were written, people didn't own Consumer Electronics, like they do now, at least where I lived they didn't!.
But, even so, it's not many is it?.
Also Paul, over here, there are no real hard and fast rules for socket-outlet placement, excepting(obviously)Bathrooms and other Damp Areas, in general, we tend to mount the sockets at 300-400mm above floor level, the exceptions to this rule, would be a Laundry or Kitchen. [Linked Image]
