In reply to Helen ~Taylor:
Consider 2 policies it works out cheaper.
Get one to cover death, sickness, incapacity and unemployment for 1yr only - this policy will pay for 12mths from claim only. Check the clauses for unemployment very carefully.
Get another that will pay for life but only from 12mths after claim. This will take over when the 1st lapses if the circumstances remain. Don't bother with unemployment cover for this policy (if you are well you should be able to find employment within a year).
You can take mortage cover for more than the value of your payments (I think 50% more?) take advantage of this.
The two are normally cheaper than a single policy because of the reduced exposure to the insurer in both cases. If you have the time go and see a mortgage advisor who'll know about such policies, it's worth the time.
