showers

[tpk1980]

can a shower be supplied by other feeds i.e. cooker supply as live i first floor flat and struggling to get new supply to CB

 

[smars]

A shower must have its own circuit and cannot be supplied from another circuit.

If you live in a flat and don't want to start chasing out walls, try using mini trunking.

Do you mean use the cooker cable to supply a shower instead of the cooker?

Then subject to jointing it satisfactorily so that it can be extended, and it following a satisfactory route if concealed, and the current carrying capacity of the cable adjusted for any installation factors, and the rating of the MCB all being OK, yes.

If you mean as well as the cooker, then no.

But unless you have a very unusual cooker circuit, it won't let you have anything bigger than a 7.6kW shower, which will be rubbish.

Better clarify what the intended shower is here. If it's one which electrically heats the water, then as above. If we're talking about just a pumped shower which takes hot water from the existing system, then it's quite possible to run it from an existing circuit.
