The IVA UK market is huge and there are a number of companies who will be able to help you arrange an IVA.
What you have to decide is whether an IVA is right for you. An IVA should only be entered into if you have severe debt problems, normally over £15,000 at the very least. If you're being advised to think about an IVA but have debts significantly less than this amount then you might be getting bad advice. Look into the alternatives and see what benefits each agreement holds.
Another thing to consider if you do have massive debts is whether you can afford to keep up the repayments you'll be required to make on an IVA. If you don't know, an IVA UK agreement will slice off a massive amount of your debt but you'll still have to make repayments on the remaining amount. If you have no money coming in at all then you'll probably have to consider a bankruptcy instead.
If you're able to consider an alternative to an IVA, like a debt consolidation loan or debt management plan then you definitely should. An IVA is a serious procedure and can leave a black mark against your name for a longer period of time. So if you're thinking of taking on an IVA, think long and hard before entering into an agreement as it's not always the best course of action, even if you do have severe debt.
