is it a smokers house? ive had this happen with nicotine before.
it has to be washed down with sugar soap first ,rinsed then painted.
if it is caused by nicotine another coat can reactivate the problem,the best way round it would be a coat of oil based eggshell as a finish or a thinned coat of undercoat followed by emulsion if you want a matt finish.
depending on the size of bubbles you may need to sand and apply fine filler first.

Cheers for reply , its a bedroom so has not been smoked in , the bubbles were only in a small area to make things awkward cheers

most likely a greasy hand mark or contaminated with something else similar.
if it is just one small area id still try the above cure but just undercoat the bubbly patch and re-emulsion that one wall
