    Cable from heater element to dual switch colours are blue - brown - black - yellow/green and mains wires are 2 black and 1 red.

    Bath is L1 Sink L2 - L - N . Top right corner Load N.

    Take a picture, you should not need to guess at the colours. The basic operation of a dual element immersion is that you switch the live to a common netural. However some immersions have neutral as brown and some as blue so you cannot go on colour, you need to find your common wire which will be the wire connected to the thermostat.

    If in any doubt call an REC. These are high load devices and you really don't want to wire them wrong (and they will seem to work wired wrong, so if it's heating it's not necessarily wired correctly and safely).

    Brown/black can be sink or bath

    Years since I've seen any new heaters with neutral as a phase colour

    They aren't as rare as you think. You will see quite a lot of immersions in houses with a brown neutral and blue/black sink/bath.

    Sorry, you are referring to new immersions indeed, these won't have these colours but older ones will.
