Any problems there?

I wouldn't recommend it. It's OK for other 3kW devices like kettles
which are used intermittently, but not really a good idea for immersions
IMO.

I did wire up the immersion in a previous house with a plug and socket -
good quality (MK) ones - but the plug got too warm for my taste and more
so when the door to the cupboard was closed. I replaced it with a FSU
in the end. That was for a pretty old immersion like yours which does
probably pull the full 3kW. A modern one might be "eco" and draw less
current.

How is less than 3kW eco? It just takes longer to heat the tank.

And wastes a bit more heat in the process, so actually uses more
energy than a rapid heat-up. But that's Euro-logic for you! Goes with
the proposed ban on high-power kettles, toasters, you-name-it.

for fear of giving more fuel to the Brexit campaign, but no doubt if
Brexit fails, it'll be back on the agenda toot-sweet, as they don't
say in France).

The only way a low powered kettle would save electricity is making us so ****ing impatient we don't bother with hot drinks any more.

Anyway, why are we saving electricity? Electricity is a renewable resource, it can be created from anything.

And the amounts used for vacuum cleaners, kettles, etc are miniscule compared with heating.
