Noisy worcester 240 Combi Boiler high pitched whine?

The boiler emits a very loud constant high pitched whine which sometimes reduces after an hour or so. The boiler is fixed to the wall in a very small kitchen & the baby's room directly above. Can anything be done?

Not sure, but mine whines too, I think it is the Flue fan and they can be replaced.
