Just a few things to think about. Firstly Death in Service benefit is not guaranteed. It is up to the trustee's to determine whether there is enough money in the pot at the time of claim as to whether they pay out. If you or your husband changes the company you work for you will no longer get the benefit and your premiums may be much higher if you decide to set up a policy then.
Also think about not only repaying the mortgage in full but your monthly outgoings until your youngest is 18.
For example.
I have Life Cover for £100,500 Level Term. Covers my mortgage
I have Life Cover for £16000 per year until my youngest is 18 (Family Income Benefit) which covers our outgoings
I have Critical Illness cover which pays 3 years of my salary to give me time to recover or die.
I am 35 with two children. This cover costs me £41 cpm.
Most brokers will charge nothing for writing your life cover. Please please please consider your circumstances.
What happens if you are off sick? Do you get full pay for a while, half pay for a while and then SSP? If so you should also be considering income protection if you are reliant on both incomes, or at least covering the wage earner whose income would be more missed.
You may think spending the money is abhorrent but I have clients who have called me and told me if I hadn't nagged them about it they wouldn't have taken it, and now they would have lost their home.
Please don't be one of those people.
