Have you got a leak? Looks like water damage to me.

Directly behind this wall is a bath though and it only seems to be 1/3 of teh wall which is like that where the bath starts and finish so not sure if its related?

dont have any water leak though


but picture 2 is on the other side of a kitchen and there is no water stuff nearby!

thanks

looks like thistle bonding undercoat and condensation or damp has caused this, bonding in the kitchen and bathroom dont fare to well unless protected once exposed to moisture it will suck it all up "remedy" take the lot off replace with render and also check for a damp problem "thats if im right and it is bonding"

The white powdery stuff is efflorescence (salts) and is most commonly caused by moisture within the substrate drying out. Excessive amounts can cause the plaster to crumble, which is seemingly what has happened in your case.
As the other guys have suggested, this seems to point to some sort of moisture issue. Whether it be a leak, damp or whatever that is causing it, you will need to address it at source, otherwise, as I'm sure the others will agree, any plaster repair will only be cosmetic and the problem is likely to re-occur.
You say there is a bath on the other side of the wall, so there is a possibility that even the slightest leak (through pipes, sealant, waste) could be working it's way to this point and causing the problem. You need to thoroughly check for signs, but, if can't find anything, it could be a damp issue which is common around the lower parts of walls.

Not that it makes a great deal of difference in your case, but what I can determine from those pics is not either a hard or soft form of efflorescence, but a degradation of a paint system caused by the ingress of moisture.

Well, if you can't see efflorescence in those pictures then you'd better give up the decorating.

Well if you can see it perhaps you should become one.

Thanks!

Im a newbie so im gonna attempt this myself hopefully to get some practise!

Any suggestions or places to get decent type of plaster? homebase? B&Q i guess?

Yes but the trouble is you have to buy big bags. You need an undercoat plaster and skim coat.
