As breezer has unhelpfully pointed out, it can be either live or neutral. However, it can't be an earth.
It's conventional to connect the live (aka phase) into the thermostat, then the thermostat to one element terminal, then the other element terminal to the neutral, so the best answer to your question is "live, probably".

More specifically, live when the thermostat contact is made.
It will be neutral when the stat contact is open.

Oh yes that's very helpful.More specifically, live when the thermostat contact is made.
It will be neutral when the stat contact is open.
Let's start calling all switched live/phase wires "unswitched neutral" when the switch is open circuit. Perhaps it should go into the 18th Edition.
Hey! We could also rename all neutrals as "earth" when the installation isn't energised.
There's all manner of things that we could be "more specific" about...
