Things change, and agreements vary, But this is how it worked for me.
In year 1 my wife got a job which was better paid than her previous job, my more than 100%. We informed Haines Watts (now RSM Tenon), and they said thanks, we will review your position in due course, i also received a decent pay increase. At review they increased our contribution by 50% of the recalculated disposable income, this sent our contribution up from about £400 to £600. I was more than happy, and year on year they did the same, until in year 5 we were contributing £1000 per month. I actually found that because i was lucky and had a well paid job my IVA got easier year on year, because i was allowed to keep half of the increase. On top of that the interest rate fell through the floor, and so did my mortgage payment, so this also benefited me as i got to keep half of the decreased payments, the rest went into the IVA. I didnt have to contact my IP unless i had a problem, which luckily i never had, or i got more than £500 in windfalls, which until i got made redundant i never did. I declared the full amount of redundancy to my IP, and made a full and final offer which equated to 10% of the windfall, plus my remaining payment. This was accepted. To be fair to my creditors, they could probably have pushed me for more, but the way my IVA was conducted was exemplary (not my words) i paid as much back as was possible, i was honest throughout from start to finish, i felt (and still do) duty bound to pay back as much as i possibly could. It is this sort of thing you need to keep in mind, because if you are fair and honest, do as much as you can, and stay true to the deal, then in time to come you may want to settle early, and if you have gone the extra mile it will be looked upon favourably. I know our creditors want as much back as they can get, and lets be fair if you or I are owed money we would also want it back. Our creditors are human just like us, and they have a job to do, but they have no wish to crucify us when we have our problems. So if you play your part and make the effort one day it may well be rewarded just like it was for me.
If i ever find myself in a position where i have enough money, i would search out my former creditors and pay back every penny I ever owed even though it has now been written off. I call it pride.
