The IP should be completely transparent about their fees - and should have given you a figure. It is common to use the explanation that these are funded by creditors indirectly, but you should still have been told the amounts. This is usually detailed in engagement letters which are issued to you right at the beginning of your involvement with the IP.
The dividend of 29p you have been quoted, represents the amount which will eventually be distributed to your creditors, after costs have been taken into consideration.
NatWest are generally a supportive creditor, and Andy's advice re token payments is absolutely correct - I am suprised that your IP has left this up to you to work out however.
