    not only should you fill the holes, but you should apply a layer of sand and cement skim throughout....

    otherwise you will have no air tightness layer

    I forgot plasterer has that included in price. So Should i just 3/4 fill hole with expanding foam and let plasterer finish it off when he is skimming?

    No. Let the plasterer completely fill with sand and cement.... Or you fill beforehand.

    Expanded foam will deteriorate over time
