What is the best way to kick start some composting action? Just add
water. use Garotta or similar, wee in it?

I favour Garotta cut with ammonium sulphate to restart a smaller heap.
(or some compost from a working hot heap)

Does it need some fresh vegetation added?

Mainly I expect it needs some air and water introduced to get things
going again. This drought has seen my compost heap stall for a while.

Grass cuttings can pack too densely to be easily wetted from above - and
too much water with no air will turn it into smelly anaerobic slime.

I'm reluctant to empty it all out then put it all back in again at the
moment due to far too many things to do.

Poke some hole in it with a stick or a garden fork and then add some
water and/or Garotta would be my suggestion for a lazy quick fix.
