For your PPI claims to be made simple it is a good idea to make a checklist of all the steps that you need to take in order to have a good chance of receiving compensation. The main counter attack that you will likely be claiming is that the initial policy was not made clear to you. This includes the assumption that the PPI was not optional, but rather it was required in order to receive the initial loan. This is usually due to misrepresented information conveyed to you by the lender.
To ensure your PPI claims are made simple you might want to consult with a financial advisor or advising company who have knowledge in the PPI claims process. This way you can ensure that your PPI claims are completed to a high standard and you have someone with expert knowledge to guide you through the process.
