Yes Alan, I claimed and am glad I did. Just write to your lender and they will send you the forms to fill in- as LFF says, don't bother with claim handlers, it isn't necessary.

I didn't have proof of what was advised at the time of taking out the endowment, but all lenders assumed at the time that the debt would be paid off and even provide an extra lump sum for cruises and so on... All I needed to fill in on the form was details as I remembered them. Lenders are aware of errors that were made at the time and are generally keen to settle up.
