If you are TT earthing the other end, then you don't need an earth
conductor. Just sleeve the black as blue and don't connect the grey
conductor to anythying.

It would be better to connect to grey to the armoured at both ends in this
case rather than just leaving a floating cable. The house end of couse being
connected to the house earth.

The accepted colours for such wiring is grey (sleeved with blue) used as
neutral and black (sleeved with green/yellow) used as earth.
