What would cause the metal casing of both a microwave and a kettle to

The voltage is not high enough to be uncomfortable, but you certainly
can feel it. Tis a bit like a weak electric fence when touched.

However, the appliances do not do it when plugged in to another socket.

You have a socket without an earth. Fix that, *priority*.

In this case the metal case will be roughly at 110v AC with a fairly
high impedance, via the RFI filtering.

but since both appliances play with water and electricity, that could
change to 240 and low impedance.

Which is why I said "Fix that, *priority*."
