In reply to Albie:
I disagree. Don't just fill it in but instead shop around.
Financial services companies make their money because people don't spend even 30 minutes hunting for the best deal. This is because they're either a) scared of numbers and firms blind them with science, or b) feel it's a lot of work.
But - particularly with your mortgage - shopping around and re-mortgaging regularly could save you THOUSANDS of pounds PER YEAR.
And if someone offered you thousands of pounds for 30 minutes work, you'd doubtless take it.
The point above about smokers makes my point. Of course smokers, on average and all else being equal, have shorter life expectancies. But even this disadvantage when hunting for a policy can be offset by the huge saving of hunting for a good deal. The same doubtless applies to climbers.
See if www.moneysupermarket.com allows you to search for the best life insurance policy ( i think it does). Remember it doesn't get quotes from every life insurance company, but it should definitely get you a competitve deal. And the difference between the very best deal and a very good one is peanuts compared to the rip-offs provided by some big-name financial services companies.
