Once issued an Administration Order is registered at the Registry Trust and entered on the Register of Judgments, Orders and Fines. This means it will appear on your credit file and as a result will affect your credit rating which will almost certainly make it more difficult for you to get credit.
The Order will remains on the Register of Judgments, Orders and Fines for six years. When your administration order is finished the court will change the record on the Register to say that you have paid the debts. This may make it a bit easier to get credit though you may still be affected.
After six years, the administration order will be removed from the Register and your credit file. This means it will no longer affect your credit rating when you apply for credit.
Note: If you pay your debts in full under the Administration Order you can ask the court for a certificate of satisfaction. This proves your debts have been repaid. However the record will remain on your Credit File for the full 6 years. It costs £15 for a certificate.
