I have two ring mains, (downstairs and upstairs) both fed from 32A MCBs

so I assume there's a spur somewhere ?

I wish to add a small ring of 13A sockets (6 x 13A double sockets) in a
new conservatory. As the downstairs ring is rather busy with kitchen
appliances etc, I am planning to add this new ring to the 'upstairs' MCB.

A: Can I do this ?

B: Can I take a 6.0mm T&E from the consumer unit to the conservatory,
and connect the other end to the new 2.5mm ring closer to the
conservatory ?

To deal with the Upstairs ring aspect. I wouldn't. If you, or one of
yours, or a future owner were to have a fault, trip the breaker for
downstairs and then fry, you would feel responsible?

In a conservatory, I would be especially keen to have an RCD on the circuit.
