0% on balance transfers

[neveranycash]

Hi. this might sound stupid but when a company, for example capital one, offer 0% on balance transfers, does this mean i wouldn't pay any interest on the amount i'd transferred from another card?? I have �2000 on a Halifax one card and i want to know if i transferred that to another would i not have any interest to pay on it, as long as i didn't spend any more on the new card??? I'm currently paying around �30 a month in interest, and would like to know if i'd be saving if i transferred. Sorry to sound so thick....
