Hi all,

I have a bad black mould problem and am going to have to redecorate
several rooms.... I have found some Dulux trade antifungal white
emulsion which will do the ceilings but would like to do something about
the walls. Does anyone know of an additive that could be added to
standard emulsions, or a treatment that would use to inhibit the return
of the mould. I've spent a lot of effort with mould cleaner and
scrubbing to remove it and I would like to keep it away as long as possible.

That's the wrong fix. You need to find out why it's forming and
cure the cause. Most likely it's condensation, caused by poor
ventilation and/or excessive moisture production and/or uneven
heating and/or poor insulation.
