By visiting http://www.mbnappiclaims.co.uk/ you will know about all the needed points before you go for the PPI claim. It is a worth noting fact that PPI claim can be sold only to those individuals who are between 18-65 years of age. So, if you had applied for the PPI when you were less than 18 years of age then you can claim for the missold PPI. If you are self-employed, unemployed, or retired then you really have good grounds for PPI claims. But there will be no meaning of PPI if you had grabbed it when you are self-employed, unemployed, or retired already.
