In theory, you should be able to apply for credit again within a week of receiving your Clearance Certificate. But we have seen that the credit bureaus take longer than that to clear your record. We would suggest waiting three months before applying for new credit.
Pull your credit report about one month after receiving your Clearance Certificate. Check that everything is in order before applying for credit. If you see that the Debt Review listing sill reflects on your credit profile contact the credit bureau immediately to rectify the listing.
Also keep in mind that even though your credit score might be good, credit providers might still have a flag indicating your history on their internal systems. They must also remove those records. It always remains the decision of the credit provider whether or not they want to extend credit to you. If they do decline your credit application, you have a right to know exactly why they declined it.
