In a stadard modern house, what is the maximum current the immersion cable can carry? The cable is already there and the house is about 5 years old. Can I replace the 3kW immersion with a higher rated immersion?
thanks

You'll struggle to find a water heater above 3Kw for a domestic cylinder. Using any more than 15 amps resistive load for the circuit will seriously effect the cabling, so it is not recommended.
The immersion circuit is frequently run in 2.5mm cable. This would be enough to run 2 3kW immersion heaters, or a single one up to 6kW.
Caveats:

Are we now not now talking about a radial circuit with which a maximum of a
20 Amp fuse/MCB supplying 2.5 T&E (not on a ring) cable can be used?-- Adam
