Dear Sir/Madam,
Ref: xxxxxxxxxxxxxx (Your mortgage account number)
I took out a mortgage with you on (date) and the exit fee was deemed to be (fee stated on your original contract). When I change my mortgage, I was charged a fee of (fee you paid).
***[if the above paragraph is not the same as your circumstances, use the paragraph below in it's place]***
When I took out my mortgage with yourselves, it was not stated that I would have to pay an exit fee if I switched my mortgage provider once the initial offer had ended. However, I was charged (state fee you paid) ]
Following guidance from the Financial Services Authority, I am writing to request that you reduce my fee so that it matches the fee that was originally stated when I began my mortgage.
Should you not be willing to accept my request, I will be taking the matter up with the Financial Ombudsman Service.
Yours sincerely,
