You can ask for a payment break if you need something done urgently but your payment will be added on to the end of your IVA.

The greatness of a man is not in how much wealth he acquires, but in his integrity and his ability to affect those around him positively.

You can have payment breaks at the discretion of your IP --- but, as Kallis says, these will be added back on to the end of the term. Some agreements limit these 'lifelines' so they should be used wisely.
My opinions are merely that .. opinions based on experience. Always seek professional advice.
