First Active Mortgage payment protection insurance - what does it cost when compared to a stand alone policy?

First Active web site suggests getting mortgage payment protection insurance from Direct Line. So how does it compare on cost to the Paymentshield administered policy ?
Well Direct Line state that they charge £5.45 for each £100 of mortgage payment you want to insure.
The Paymentshield insurance policy offers it at a cost of £3.95 per £100 for accident, sickness or/and unemployment and for just unemployment on its own it costs £2.45 per £100 of mortgage payment.
So on a mortgage costing £750 a month there is over £11 a month to be saved. With the current credit crunch, that could go a long way !
