Check to see if concrete is at least 150mm below your dpc or floor level if not then cut a channel along wall.
Render shouldnt go down to meet concrete, as water will wick up, you should cut render away, about 150mm up from concrete and fit a bell cast bead.
Sort this out first and get plenty of air circulation to dry out.

Hi,best thing to do would be to cut away concrete at least 6 inches from bay,dig down 6 inches and fill with gravel to make a soak away.

Yes the outside level should be around 3 bricks below the damp course, and the render should not meet the concrete. I note that you do not say if the damp is at the bottom of the bay or higher up. you should get a local damp proof expert to have a look as things are not always as they seem. I have been in the trade for over 30 years.
