Many thanks once again.

I understand on this clearly now.

I can take tails from the meter into my 100amp switches fuse which I'll install to the right of the meter at high level in the meter cupboard.

From the sf isolator I'll run tails to the Henley block which supply's the three feeds.

Also I'll use containment to protect and neaten the cables inside the meter cupboard
