Plevin refers to the ruling of a Supreme Court decision from 2014 in relation to an undisclosed commission. Susan Plevin was sold a Payment Protection Insurance policy and the lender failed to disclose the level of commission on the policy which was 71.8%. The Supreme Court ruled the relationship unfair on the basis, the commission and the percentage of commission were not disclosed to the claimant.

Based on this decision, the Financial Conduct Authority (FCA) formed a new approach which stated, a 50% commission or above would constitute the ‘tipping point’. It is widely recognised anything over this threshold would make the relationship between the lender and borrower unfair. A Plevin claim can be made even if the previous complaint was rejected by the lender or the complainant missed the August 2019 deadline.
