    Its been there 1 years.

    I havnt noticed the noise during the day, I think its a night thing.

    Anyone any ideas about this? Should I run from the premises now?

    Start to knock the breakers off one-by-one to try to assertain the problem. You need to get it looked at though. It could be a bad connection. Is it only at night?

    Do you have storage heating?

    If you have storage heating then you have a contactor that switches on during the night.
    A very noisey contactor is probably broken or has a loose connection.
    If it is more of a humming noise then either it is vibrating against the cover of the consumer unit or it is a poor quality contactor and should be replaced with a type that has an AC/DC coil.
