It doesn't pay them off in full, but it does go a long way towards paying off more of your debts. I don't think the IP gets any more though as their fees have already been sorted.
However, I do know of at least one poster on here who will be looking to pay back 100p in the pound, or as close as, purely by working a lot of overtime, so it is possible to pay back in full.
I never get the opportunity to work any overtime, so it never affects me, and so far have not had to pay anything across from any payrises. I do have the 10% plus 50/50 clause though.
As regards regular overtime, I know Melanie does not include overtime as, even though it may be regular, there is no guarantee, particularly at the moment, that it will continue.
I'm sure the creditors will be more than happy to take any extra that can be paid across to them.
