Will the step be above the DPC then

yes part of it will be, is this ok to do?

In that case I would be tempted to put a cover flashing in the course above the step.

If you put a plastic membrane against the wall, water can still go down the back of it.

If you mark it our perhaps a sealing mastic painted on the wall would be an idea

Leave a 50mm gap between the concrete step and the brickwork
( l promise nobody will fall down the gap )

could i paint the bricks behind the new step with some kind of damp seal stuff,
i cant leave a gap, her indoors has said no

Then her indoors needs to find out why you have a damp course and why it should not be bridged

Or look forward to posible future problems with the step built against the
brickwork

It would be better than anything else other than a cover flashing
