Hi skint and welcome to the forum
This sort of post is starting to become too frequent - I simply cannot understand why some members of my profession continue refuse to deal with their own clients. But it is better to confirm things in writing, so that he can see what you are trying to achieve.
If you go onto the insolvency service website - and onto the "Find and IP" page - type in your IP's surname, and lo and behold you will find an e-mail address for him. Use of delivery and read receipts is also a good idea, so you can track if he has read your mail.
Let us know how you get on.
