Hi,
Just to point out that the cover is for the first 5 years of the loan only NOT the life of the loan, once the 5 years is up and you have claimed your cashback it is perhaps advisable to use the money to buy a policy with a different insurance company to cover your payments if you so wish.
Another point, Insurance Premuim Tax is only included in loans taken out a couple of years ago where your insurer is Cassidy Davis, newer loans in last year or two will not have to pay this due to the insurance being with Barclays Insurance in Dublin, (as the insurance is not UK then no IPT to pay!)
One of the main things to note is that you will NOT get any cashback if you are 3 months in arrears, if struggling to make a full payment then always make a partial one as this can protect the cashback element of the loan!
One other thing, if you buy joint cover the second named customer will only be covered if they die, it only covers the first named person for life, accident, sickness and involuntary unemployment - read the small print before you buy.
You also have 30 days from start of loan to cancel the PPI if you are not happy but this needs to be in writing signed by all parties to insurance and I would advise sending the letter recorded delivery as I would also do when you write to claim the cashback.
