What was the compensation for? If it was for pain and suffering a lot of companies will let you keep it but you should have informed them.
If it wasn't then they won't be very happy at all and may well insist that you pay it across bit by bit.

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.

Hopefully, as Kallis says, it was for pain and suffering and that your IP is one of those who accepts that you can retain this.
If not, they will expect it to be repaid, either over the rest of the IVA or by extending the IVA to cover the loss. It would, in my opinion, be unreasonable to expect you to be able to find a lump sum to repay in one payment. However, there is a large element of trust in running an IVA, which you have potentially damaged. Your IP might be a little more stringent going forward.
My opinions are merely that .. opinions based on experience. Always seek professional advice.
IVA Completed 23rd July 2013 .... C.C. 10th January 2014
Best to pick the phone up on Monday and let them know.
Worst case will be you have to pay it in over the balance of time.
Let us know how you get on - no problem is not resolvable so always keep your IP informed
