Well done on getting this far. Are you a homeowner and, if so, has equity been addressed already ? Hopefully, it has, or does not apply and you can proceed to formal completion.
IP's do (though shouldn't really) vary slightly as to their closure procedures. But, generally, they should do a final review, concentrating on your income for this final 12 months. So, they will likely require wage slips, P60 and bank statements as per previous reviews. In house they will then re-visit previous reviews to dot i's and cross t's and finalize claims and dividend distribution to creditors.
Once that is all done you will get your certificate of completion ( in reality a nondescript sheet of paper).
My opinions are merely that .. opinions based on experience. Always seek professional advice.

They may want the usual info as per your annual review but they will let you know. Well done on reaching the end.
