Yes. No matter when the policy expired, provided the PPI was mis-sold, you are entitled to make a claim.
Can I still make a claim even if my PPI policy has expired?
Your PPI Claim starts with a Free PPI Check service. Our PPI Claim fee of 20% + VAT (so 24%° of the total redress offered by your lender) is payable if your claim is successful. That means if we don’t recover you anything, you don’t pay us a penny
