Update
I followed a builder friends instructions and dropped the render down another course over the original brickwork and changed the bead from a stop end to a drip bead.
So far no problems and have now redecorated interior.
Thanks, I had previously set up a hose with a spray up onto the window on and off for a couple of days and saw no penetration on the inside of the blocks.
I have taken 18 inches of render and the stop bead off.
I have stuck a 6 inch visqueen damp along the joint with a thin bead of silicon...

Within a couple of weeks we had water penetration again.
I have tapped all round the...
