I've just moved into a lovely house and discovered some excellent
herbs in the garden, however they were almost overgrown with weeds.
I've taken some complete rocket, lemon sage and chive plants and some
fennel cuttings, and replanted them straight in the soil. I've given
them a good watering but after a day they still look very listless.
Would it be best to cut them down so they regrow?

What is done is done - but why didn't you remove the weeds instead of
the plants!? You are right in suggesting to cut them down. I would.
But not sure a cutting from the fennel will work. Herbs are cheap and
easy grown from seeds. Just sow some more seeds around what you have
replanted to satisfy your supply. And be patient ;o)
