Question-05. What might I be able to claim

In the first instance you would be seeking to have all “abusive” clauses removed from the mortgage contract, this will have the immediate effect of reducing your mortgage payment and ensure future savings.
Secondly you are entitled to reclaim all overpayments including interest, which could push compensation above €20,000 in many cases.
Thirdly you can apply to recover your set up costs and insurance premiums.
