If you are using bonding on an external wall, make sure there are no damp issues,

Do you know why plaster blew in first place so it won't happen again?

It has lifted above the window where the concrete lintel was, I am presuming it hasn't keyed well to it or they didn't use a pva strong enough? doesn't look damp in that area.

I expect they used browning as its not really suitable over concrete, bonding will stick without pva ,just needs to be lightly dampened

There is a white chalky substance about 10mm thick behind the plaster around the whole room. House was built in the 60's Ceiling hasn't been plastered they just painted the plasterboard!

Sounds like a lime plaster of some sort,
