Plaster was multi finish from BnQ

There is an insulated water cylinder on the other side of the wall in
a cupboard

Plaster was well within the date stamp

Wall is an internal brick wall - some of the bricks have lost the
smooth oustide finish which came off removing cement there previously

The plaster was put directly onto the brick.

Today there is cracking on thinner layers put on top of the base
plaster coat as well. All carcks are quite pronounced 1-2mm wide.

Damn! you need a base coat on exposed brickwork first ie carling bonding
coat or dot&dab the brickwork.

Not sure how easily rescuable this is going to be now...

If the finish coat (which you've used as a scratch coat) is well
bonded to the brickwork and the surface is flat, you might be
able to get away with just a proper finish coat reskim on top.

If the finish coat isn't well bonded to the brickwork (and finish
coat isn't wonderful at bonding), you'll have to hack all the loose
stuff off.

If the surface isn't flat, then that will need leveling off with
something like bonding coat before skimming. Use a straight edge
(i.e. a piece of unwarped planned timber) to check for flatness.
