Ditto. Courgettes are very sensitive to cold and wet. Normally by the end of May we should be safe to plant out in a well drained sheltered bed but as everyone here says, this year, it's still too risky. A couple of inches down in the soil and you'll find it pretty cold and damp.
I grow some in containers and aim to repot mine into these this weekend but house them in a corner of the GH for a couple of weeks.
