I'm wondering if it would be ok for me to use a supply for an old
electric shower that is no longer used. I was thinking about dropping
this supply down from the attic into the kitchen to a separate CU?

That would be a little odd, but would work. I would be inclined to drop the
separate CU, replace your main consumer unit with something modern and use
the 10mm shower circuit as a kitchen radial socket circuit off an RCBO (or
RCD side of split load).

Then the fridge/freezer could have its own non-RCD circuit (means disruptive
work) or could be taken off the cooker circuit (minor dodginess, but would
be perfectly fine, especially if you have a cooker switch sans socket).

There's oodles of diversity available on the cooker circuit (assuming 32A
MCB with 6mm), especially if the fridge/freezer is FCUed in, rather than
leaving a socket, so muppet can't install fan heater on it.

Hi everyone

I'm re-wiring and installing a new kitchen for my girlfriend and
looking for some advice!..apart from don't do it

Currently there's a supply for the cooker 6mm^2 via the usual cooker
swith onto the CU. There's also 1 double socket from the ring.

The kitchen will have a new electric hob and oven (around 9kW total),
extractor hood, fitted dishwasher, fitted washer/dryer, fridge
freezer, cabinet lighting, plus the usual kettle (3kw?), toaster,
gizmos etc etc.

There's quite alot more load than there is currently and i'm not keen
to extend the ring further for the appliances etc.
I could add another dedicated line back to the CU for just the
kitchen..although this would be tricky.

I can then take a dedicated supply to the fridge/freezer and and then
use another circuit/s for the appliances and sockets (with a spur to
the extractor hood)???

If that sounds ok...whats the best way to physically extend the 10mm^2
from the attic to the kitchen (are there heavy duty junction boxes?)
What sort of arrangement as far as the new CU would you recommend?
MCB's etc?

The main CU is an old fuse type (*6) (with no RCD..i think..only had a
brief look) and will need upgrading so i want to keep that in mind
also.

Any advice appreciated as always...
