If you can recall the firm or IP, they may still have a copy. Maybe also try the Insolvency Service, who would have been given a copy also. A lot will depend on the exact time lapse involved as many institutions will destroy old records after 6 or 7 years.
My opinions are merely that .. opinions based on experience. Always seek professional advice.
