Cabling to Shower - Help required

[derekreid123]

Purchased a new 9.5kW electric shower and would like to know if can install using the existing wiring and MCB.

The existing wiring is 6mm approx 12m run with 50A MCB and goes through a 45A DP pullcord switch. The cable runs within loft space for about 3m where wool insulation is located.

Would this be sufficient?
I would rather not run a new 10mm cable if i can get away with.

Would i require to upgrade the cable to 10mm or change MCB to 45A.

Any suggestions would be most appreciated.

Thanks
