When referring to treble clef parts in the British Brass Band style, the written C below the staff is the fundamental of the horn. So if the part is for BBb tuba the treble clef C below the staff is actually a concert Bb which is open. If playing the part for EEb tuba the treble clef C below the staff is actually a concert Eb which is open for EEb tuba. So if you are playing the BBb tuba part with a BBb tuba the fingerings are the same as the fingerings for EEb tuba playing the EEb part.
If you start swapping parts around then you begin having difficulties. If you are playing the EEb tuba part on BBb it is easy. You pretend it's bass clef and add 3 flats to the key signature.
If you are playing the BBb tuba part on EEb tuba, it doesn't work the same. You actually have to tranpose. What looks like a Eb bass clef (written as C treble clef) is actually a Bb. So you have to take everything down a fourth.
