Personally, I routed the cables horizontally in the kitchen (it's
basically
the only time I would consider horizontal shallow buried unprotected
runs).
The sockets come thick and fast and are horizontally adjacent. It saves a
lot of cable and means you don't run into total ring length issues which
can
quickly come up if you are using 4m per socket drop plus the distance
between.

Good point, what is the length limit for 2.5 T&E ring circuit?
At the moment, the kitchen is just an extension of the downstairs ring, but
I am considering separating these.
