Your bank should keep cheques for at least six years. Remember, some banks charge a fee for reproducing statements, so if you need to provide a copy for a lender or the taxman it can prove an unwelcome cost. If you bank through the internet, you might want to print off and keep a hard copy of your statements. It is also a good idea to check with your bank how long statements are available on-line and whether hard copy statements are available.
