Borrowers are able to waive their right to protection from the FCA in regulated financial transactions (such as Residential Mortgages), if they are able to have a statement completed on their behalf confirming an annual income or NAV higher than stipulated levels. After the Mortgage Market Review, those figures were set at £ 300k income or £ 3m of assets throughout the year. The statement needs to be completed by an appropriate person, such as an Accountant. The provision is there as the FCA recognises that higher earners may have more sophisticated needs and a better understanding of financial contracts.
